Lytron’s broad range of heat exchanger technologies combined with five decades of thermal transfer experienceenables us to offer tailored solutions for a wide range of applications. Our four types of heat exchangers can all be customized and integrated into subassemblies.
Tube-Fin Heat Exchangers 6000 Series, OEM Coils, Aspen, and 4000 Series
Our tube-fin heat exchangers consist of copper or stainless steel tubes expanded into copper or aluminum fin. Tube-fin heat exchangers are cost effective and offer good heat removalfor a wide range of applications including lasers, electronics,compressor cooling, semiconductor processing equipment, andsolder reflow ovens. Our copper tubed 6000 Series and OEMcoils, and stainless steel tubed Aspen and 4000 Series offer compatibility with a wide range of common coolants.
Flat Tube Oil Coolers ES Series
ES series oil coolers are designed for optimum cooling with poor heat transfer fluids such as oil and ethylene gly-col/water mixture (EGW). The aluminum flat tube fluid channels are vacuum-brazed with aluminum fin and a frame for a rugged and lightweight construction. They are ideal forcooling x-ray tubes, aircraft engines, hydraulic fluid, and highspeed spindles.
Plate-Fin Heat Exchangers
Vacuum-brazed aluminum plate-fin heat exchangers are our highest performing heat exchanger. They can be used for air-to-air, air-to-liquid, and liquid-to-liquid cooling. All plate-finheat exchangers are custom designed to match your precise performance and size requirements. Applications include condensers, evaporators, environmental cooling systems, andradar cooling. Their high performance/weight ratio also makesthem popular for airborne applications such as cooling gearboxoil and transmission oil with ram air or jet fuel.
Liquid-to-Liquid Brazed Plate Heat Exchangers
Liquid-to-liquid brazed plate heat exchangers utilize stainlesssteel plates brazed together in a counterflow configuration. This offers high liquid-to-liquid cooling capacity in a compactpackage. We offer both copper-brazed and nickel-brazed versionsfor compatibility with a wide range of coolants. Applicationsinclude district heating/cooling, heat recovery, and laser cooling.

Performance c omparisonThis chart compares the performance of different heat exchanger technologies. Performance is shown as Q/ITD, the heat load divided by the difference in incoming temperature of the liquid and air. Units are not shown so thattechnologies can be compared regardless of size.
As many heat exchangers are customized, a range of typical values is shown for each technology. All performancesare compared using water as the cooling fluid.
Fluid compatibilityCoolant compatibility with wetted surfaces must be considered when selecting a heat exchanger technology. A copper fluid path is compatible with water and most common coolants. A stainless steel fluid path is necessary when using deionized water and other corrosive fluids. Aluminum offers excellent performance with ethylene gly-col/water mixture (EGW), oils and other fluids, but is not compatible with untreated water. The table below shows fluid/heat exchanger compatibility.

The 6000 Series is a high performance heat exchanger with copper tubes and fin. It delivers efficient heat transfer andmaximum reliability in a compact package.
High cooling capacity in a small envelope: The 6000 Series is engineered for performance. Its high tube densityresults in maximum heat transfer. The seamless copper tubes are expanded into copper fin (aluminum for the 6340)with an extruded full collar which ensures excellent metal-to-metal contact and improves the thermal performance.
Integrated fan plate for improved performance and convenience: The 6000 Series’ integral fan plate acts as a plenum to distribute the air flow uniformly through the core, thus maximizing performance. It also enables easy fan installation.
Reliable, leak-free, and robust: Lytron heat exchangers are designed for reliability. Our thick-walled (0.028˝/0.7 mm)seamless copper tubing and fluxless silver-brazed joints ensure the integrity of the fluid path. The unit is painted forlong life, even in corrosive environments. All 6000 Series heat exchangers are pressure tested to 150 psi (10.3 bar) to guarantee reliability.
Compatible with water, ethylene glycol/water mixture (EGW), and other common coolants.

OEM coils are the ideal solution for large volume, price sensitive users who need a high quality, cost-effective part butdo not require the additional features of the 6000 Series.
Great value: We carefully selected the materials, tube layout, and fin for low manufacturing cost, and eliminatedsome of the cosmetic features found in the 6000 Series. All these cost savings have been passed on to you!
Leak-free, reliable, and robust: Our OEM coils use the same thick (0.028˝/0.7 mm) walled copper tubing and fluxless silver-brazed joints as our 6000 Series to ensure the integrity of the fluid circuit. Galvanized side plates provide superior strength and are corrosion-resistant. All of our OEM coils are 100% leak tested to 150 psi (10.3 bar).
Compatible with water, ethylene glycol/water mixture (EGW), and other common coolants.
Both the 6000 Series and OEM coils offer high performance and reliability. The 6000 Series uses copper fins, is painted black for corrosion resistance, and includes a fan-plate. The OEM coil has a different tube configuration, uses aluminum fins, and is unpainted with galvanized side plates. OEM coils are best suited for the price-sensitive,high volume customer where the appearance is not critical, for example where the heat exchanger is hidden in the equipment.

Wider tube spacingreduces cost, weight, andliquid pressure drop.
Wavy fin edgeimproves fin strength
Liquid return loopseliminate fluid contamination and reduce liquidpressure drop
Welded, argon-purgedjoints maximize internalcleanliness
316L stainless steel tubingcompatible with deionizedwater and corrosive fluids
The Aspen stainless steel tubed heat exchanger combines low price and low pressure drop with excellent heat transferand superior fluid integrity.
• Our best value stainless steel tubed heat exchanger: The Aspen offers excellent value—80-90% the performance of competitive products at approximately half the price. We achieved this by using fewer tubes and increasing thefin density to balance the air and liquid sides. Our single piece formed aluminum frame/fan plate further reducescost and weight.
• Highly reliable: Like all Lytron heat exchangers, the Aspen is designed for reliability. 316L stainless steel fluid pathwith 0.02˝ (0.5 mm) wall thickness maintains deionized water and will not react with corrosive liquids. Aspen heatexchangers are 100% leak tested to 150 psi (10.3 bar).
• Extremely clean: Our proprietary manufacturing process expands the tubes into the copper fin without the use ofoils and our liquid return design eliminates potential particle trapping sites, which can contaminate cooling fluid.Argon-purged welded joints further ensure cleanliness.
• Low air and liquid side pressure drop: The short fluid path minimizes the liquid side pressure drop, and our tubespacing and high performance fin reduce air side pressure drop.

Stainless steel heat exchanger with custom inlet/outlet fittings
Customization Options
Custom 4000 Series style heat exchangers can be manufactured in any sizeand circuiting to match your demanding thermal requirements. Variations ininlet/outlet position and/or fittings can be accommodated and a selection ofpaints and other coatings is available. Assemblies including fans and othercomponents can also be manufactured.
See page 92 for more custom heat exchangers.
Superior construction—316L stainless steeltubing expanded into copper cooling fins
Pre-cleaned internal surfaceeliminates fluid contamination
All-welded, argon-purgedjoints maximize internalcleanliness
0.028˝ (0.7 mm) walltubing ensures fluidcircuit durability
Available with straight, beaded,or 37°AN flare fittings
The 4000 Series is our highest performing stainless steel tubed heat exchanger. It is ideal for applications where deionized water or corrosive fluids are used, and a high efficiency, compact unit is required.
• High cooling capacity in a small envelope: The 4000 series is engineered for performance. It has a high tube density for maximum heat transfer. Heavy-walled (0.028˝/0.7 mm), seamless stainless steel tubes are expanded intocopper fin with an extruded full collar. The copper fin and the excellent metal-to-metal contact between the tubeand the fin collar further increase performance.
• Compatible with deionized water and corrosive liquids: All the wetted surfaces in the 4000 Series are 316Lstainless steel, so it is ideal for use with high purity and/or corrosive coolants such as deionized water.
• Integrated fan plate for improved performance and convenience: The 4000 Series’ integral fan plate acts as a plenum to ensure uniform air-flow distribution through the core, thus maximizing performance. It also enableseasy fan installation.
• Rugged and reliable: The argon-purged welded stainless steel frame and fan plate offer durability and strength.4000 Series heat exchangers are 100% leak tested to 150 psi (10.3 bar).
Aspen or 4000 Series? The Aspen offers 80% the performance of the 4000 Series at approximately 50% the cost.Where high performance in a small envelope is required, the 4000 Series is the best option. However, when a slightlylower performance/size ratio is acceptable, the Aspen offers better value. The Aspen also has lower air and liquid sidepressure drops.

Custom oil cooler with curved tubes
Customization Options
Oil coolers can be manufactured in different sizes and tube widths, and with custom inlet/outlet configurations. Curved heat exchangers can bemanufactured as the flat tube can be bent without buckling or damagingthe internal channels. Assemblies including fans and other components canalso be supplied.
See page 92 for more custom heat exchangers.
ES Series oil coolers are engineered for high performance with poor heat transfer fluids such as oils and EGW. Theyprovide up to 2.5 times greater thermal performance per unit volume than competitive models.
• High performance: The ES Series uses Lytron’s unique aluminum flat tube technology, which has multiple extendedsurface channels in each tube. These tubes provide maximum cooling by having a large surface area in contact withthe fluid (approximately 12 in2 (77 cm2)/linear inch of tube). Lytron’s air-side fin geometry efficiently channels airacross the fin surface to further boost heat transfer capability.
• Clean and reliable: The fluxless vacuum-brazed construction results in a clean, rugged, and highly reliable part withexcellent thermal contact and mechanical strength.
• Low pressure drop: Our flat tube fluid channels and efficient header manifold result in a very low pressure drop sosmaller, less expensive pumps can be used.
• Lightweight: The all-aluminum, vacuum-brazed construction is lightweight.

Lytron’s brazed-plate heat exchangers are unsurpassed for liquid-to-liquid heat transfer. Their innovative design packsmaximum performance into a compact and reliable package.
• High performance in a small package: Lytron’s liquid-to-liquid heat exchangers are up to 80-90% smaller in volume and weight than a conventional shell-and-tube design. The counterflow design utilizes stainless steel sheetsstamped with a herringbone pattern of grooves, stacked in alternating directions to form separate flow channels for the two liquid streams. This allows 90% of the material to be used for heat transfer, making it extremely efficient.
• High reliability: The plates are brazed together at the edges and at a matrix of contact points between sheets,ensuring that the heat exchangers are highly reliable and rugged.
• Copper- and nickel-brazed versions for compatibility with a wide range of fluids: We offer copper-brazed units for use with water, EGW, and other common coolants. Our nickel-brazed units are appropriate for use with deionized water, high purity, and corrosive fluids.
• High operating temperatures and pressures: Copper-brazed units can be operated at temperatures of up to 383°F (195°C) and pressures up to 450 psig (31 bar). Nickel-brazed units can be operated at temperatures of up to 662°F (350°C) and pressures up to 232 psig (16 bar).

1. Cooling LiquidIn order to select the correct Lytron heat exchanger or oil cooler, you must first determine the required thermal performance for your application. Use the example shown below:
Step 1: Application DataLiquid type: WaterRequired heat load (Q): 3,300 W (11,263 BTU/Hr)Temp. of incoming liquid (Tliquid in): 80°C (176°F)Temp. of incoming air (Tair in): 21°C (70°F)Rate of liquid flow: 2 gpm (7.6 lpm)
Step 2: Select the heat exchanger product seriesChoose an aluminum, copper, or stainless steel heat exchanger based on the fluid compatibility. Aluminum tubing isusually used with light oils, or ethylene glycol and water solutions. Copper is normally used with water. Stainless steelis used with deionized water or corrosive fluids.
Step 3: Calculate the initial temperature differenceSubtract the temperature of the incoming air from the temperature of the incoming liquid as it enters the heatexchanger.
ITD = Tliquid in - Tair in
= 80°C – 21°C = 59°C (or 176°F – 70°F = 106°F)
Step 4: Calculate the required performance capability (Q/ITD)Divide the required heat load (Q) by the ITD found above in step 3.
Performance capability = Q = 3,300 W = 56 W/°C or 11,263 BTU/HR = 106 BTU/Hr°FITD 59°C 106°F
Step 5: Select the appropriate heat exchanger modelRefer to the thermal performance graphs for the heat exchangers selected(Performance graphs for copper heat exchangers, stainless steel heat exchangers, andoil coolers can be found on pages 64, 74, and 82 respectively.) Any heat exchangerthat exceeds 56 W/°C at 2 gpm (using a standard fan) would be acceptable. As shownin the following graph, Lytron’s 6210 exceeds the required performance.
Step 6: Determine the liquid pressure dropFrom the data given, we know our pump needs to supply water at 2 gpm. Using theliquid side pressure drop chart for the 6210 curve, the point where a vertical line atthe 2 gpm point on the x-axis intersects with the 6210 curve reveals that the liquidpressure drop through the 6210 is 8 psi (0.55 bars). The pump selected must overcome this pressure drop to ensure a 2 gpm flow.
Step 7: Determine the air pressure dropThe vertical line on the thermal performance chart indicates the air flow rate (190 CFM for the Patriot fan) as provided by our standard fans at 60 Hz. The intersection point of this air flow rate and the 6210 graph on the air side pressure drop reveals that the air side pressure drop through the 6210 is 0.24 inches of water (55 pascals).

2. Cooling AirIn cabinet cooling applications, the air is hotter than the liquid. In this case, the ITD is the difference between the hot air entering the heat exchanger and the cold liquid entering the heat exchanger. You may need to calculatethe temperature rise using the heat load and the temperature of the cool air entering the cabinet.
Example: Cabinet Cooling applicationYou are cooling a cabinet containing electronic components that generate 2400 W of heat. The air in the cabinetmust not exceed 55°C. What heat exchanger should be selected, and what is the temperature of the cool air enteringthe electronics cabinet?
Step 1: Application DataLiquid type: WaterRequired heat load (Q): 2,400 W (8,189 BTU/Hr)Temp. of incoming liquid (Tliquid in): 20°CMax. temp of air in cabinet (Tair in): 55°C (131°F) —— This is the temperature of the hot air entering the heat exchanger
Rate of liquid flow: 2 gpm (7.6 lpm)
Step 2: Calculate the initial temperature differenceSubtract the temperature of the incoming liquid from the temperature of the incoming air as it enters the heatexchanger.
ITD = Tair in - Tliquid in = 55°C – 20°C = 35°C (or 131°F – 68°F = 63°F)
Step 3: Calculate the required performance capability (Q/ITD)Divide the required heat load (Q) by the ITD found above in step 2.
Performance capability = Q = 2,400 W = 68.6 W/°C or 8,189 BTU/HR = 130 BTU/HR°FITD 35°C 63°F
Step 4: Select the appropriate heat exchanger modelRefer to the thermal performance graphs for the heat exchangers selected(Performance graphs for copper heat exchangers, stainless steel heat exchangers andoil coolers can be found on pages 64, 74, and 82 respectively.) Any heat exchangerthat exceeds 68.6 W/°C at 2 gpm (using a standard fan) would be acceptable. Usingwater as the coolant, a copper heat exchanger is recommended. As shown in the fol-lowing graph, Lytron’s 6310 exceeds the required performance, offering a Q/ITD ofapprox. 96 W/°C using our Caravel fan.
Liquid and air pressure drop can be determined the same way as in the previous example.
Step 5: Calculating the temperature of the cool air entering the cabinetNow, to calculate the temperature of the cool air entering the cabinet, use the temperature change graph for air (page 96). With a heat load of 2,400 W, and a flow rate of 250 CFM (the flow rate of the standard Caravel fan recommended for use with the 6310) we can see that thetemperature change is 17°C.This means that the cool airentering the cabinet will be:
55°C – 17°C = 38°C

1 These graphs offer a simple graphical way of estimating fluid temperature change if youknow your heat load and flow, without havingto do calculations. The graphs for water, air,50/50 ethylene glycol/water and oil allow youto calculate temperature changes for air andliquid for all types of heat exchangers.

Step 6: Calculating the outgoing water temperatureTo determine the outgoing temperature of the water we use the ‘Water Flow’ chart to find that the change in tem-perature is approximately 5°C. Therefore the outgoing water temperature is 20°C + 5°C = 25°C.
Alternative Sizing EquationThe general heat transfer equation can be used to calculate the heat load and the fluid temperature change given thefluid flow rate and the specific heat.
Q = m• x Cp x �T
Where: Q = heat load m• = mass flow rate of the fluid
Cp = specific heat of the fluid �T = temperature difference between the liquid in and the liquid out
m• can be calculated for water and air using the following equations:
Water: m• ( lbs ) = v• ( gal ) x ( 60 min ) x � ( lbs ) x ( ft3) where v• = volumetric flow ratehr min hr ft3 7.5 gal
or
Water: m• ( kg ) = v• ( liters ) x ( 60 min ) x � ( kg ) x ( m3) where v• = volumetric flow ratehr min hr m3 1,000 liters
Air: m• ( lbs ) = v• ( ft3) x ( 60 min ) x � ( lbs )hr min hr ft3
or
Air: m• ( kg ) = v• ( m3) x ( 60 min ) x � ( kg )hr min hr m3
The temperature change graphs on pages 96 and 97 plot the above equation for common heat transfer media (air, water, oil, and a 50% EGW mixture) providing a simple way to look up �T if you know your heat load and fluid flow rate.

Custom tube-fin heat exchangersThe building blocks of a tube-fin heat exchanger are tubes, fin, and frame.We have a variety of fin patterns to choose from, and can customize thetube configuration and frame. We frequently work with specialty materials,such as cupronickel, nickel, Hastelloy®, and Inconel®. To meet the stringentshock and vibration requirements of some military applications, we can provide ruggedized frames and fluid connections, and insert additional tube sheets as supporting elements within the core. Paints and coatings,including Milspec paints, are available. Fluid inlets and outlets can be customized with bends, fittings, hoses, etc., and additional sensors andinstrumentation can also be added.
Custom oil coolersLytron’s vacuum-brazed, flat tube oil coolers offer many customization possibilities. Three different flat tube widths are available, and the length and the number of tubes can be varied. The flat tube can be bent into a 3⁄8˝ (3 mm) inside radius without buckling, so heat exchangerscan be manufactured in a curved shape if needed. Custom fittings andmanifolds can be added, and oil coolers can be painted or anodized forextra protection.
