General Installation Notes General Installation Notes General Installation Note

Mounting:Small units may be

mounted by the base of

the unit or steel clamps.

Larger units should use a

mounting bracket (See

illustration); if there is a

risk of vibration,

use an anti-vibration device.

Do not over tighten mounting nuts. Do not braze or

weld mounting bracket to heat exchanger.

Safety:Each side of the heat exchanger should be properly

protected from over pressurization through the use of

an appropriate safety relief device.

Piping Installation: Heat exchanger should be piped in counter-flow.

Thread Connections- Use Teflon tape or other sealant

on male threaded part of connection to prevent

leakage. Always use two wrenches when installingpiping to heat exchanger connections to prevent

over-torque stress and damage when tightening.

Solder / Sweat Connections Use 45% silver solder

(minimum), AWS grade BAg-24 or equivalent. Brazing

flux should be AWS specification FB3C, AMS no. 3411 or

equivalent. Use wet rag around base of connector,

DO NOT OVERHEAT, purge unit with nitrogen. Do not

braze unit in the horizontal, sitting flat, position; braze

material may fall into the heat exchanger.

Welding Should only be done to a supplied butt weld

or socket weld connector. Prepare the edge of the

piping with an appropriate bevel. DO NOT OVERHEAT,

purge unit with nitrogen.

Water Strainer A water strainer should be installed

in the water inlet circuit to protect the heat exchanger

from partial or complete blockage with a 16 20 mesh

minimum, 20 40 mesh is a better choice.

Water Quality:The water media pH value should be maintained at 7.4

(not less than 7.0 and no higher than 8.0) for proper

heat exchanger life expectancy. For pH values outside

this range, the GEA FlatPlate MPN seriescan tolerate a

pH value as low as 2.0.

Highly chlorinated water (pools and spas), ground wat

with high sulfur content or sulfuric acid, and low pH,

should use the GEA FlatPlate MPN series. The standar

series of heat exchangers, copper braze, will experienc

gradual copper erosion and premature failure of the

heat exchanger.

Glycols:Ethylene or Propylene based glycols- may be used

with brazed plate heat exchangers. The glycol should

be tested annually, or more often if required, to be

sure the fluid still retains the desired properties and

protection. No permanent connection should be mad

between a system containing ethylene glycol and a

drinking water supply.

Automotive Glycols Not recommended; usage

may result in reduced thermal performance of the

heat exchanger.

Freeze Protection:It is not recommended to cool water below 33F (0.6C

due to the tolerances of the measuring equipment.

For freeze protection it is recommended to use

thermostats and / or temperature controls in the piping

Low Pressure Cut-Out- In water chiller applications,

in addition to the flow switch, the low pressure cut-ou

on the refrigerant side is the most important freeze

protection control. To prevent freeze damage and to

protect the heat exchanger and compressor,

the low pressure cut-out should be set no lower than

28F (-2C), based on evaporator refrigerant pressure

at this temperature. If part-load or transient loads cau

the chiller to cycle off, use a resetting low pressure

control with anti-cycling timer or install a hot gas bypa

control to maintain the appropriate suction pressure a

low loads.

NOTE: Use of a leaving chilled water sensor will not

provide adequate freeze protection.

With extensive experience in hydronic and refrigeration

heat exchanger design, GEA PHE Systems recommends a

few key application tips when applying Brazed Plate Heat

Exchangers to your systems.

Installation:Fluidapplications Heat exchanger may be installed in

either a vertical or horizontal position.

If the application requires the heat exchanger to be

mounted on its back, it is possible in this orientation

for the heat exchanger to collect sediment and to be

rendered useless in the system. Warranty claims due tosediment deposits will not be covered under warranty.

Steamapplications - unit should be installed in a

vertical position to ensure the condensate drains from

the heat exchanger.

Refrigerationapplications Heat exchanger must be

installed in a VERTICAL position.

Refrigeration Installation

With extensive experience in halocarbon refrigeration heat

exchanger systems, GEA PHE Systems recommends a few

key application tips when applying Brazed Plate Heat

Exchangers to your systems.

Direct Expansion Evaporators /Subcoolers:GEA PHE Systems Brazed Plate Heat Exchangers are

applicable for all types of halocarbon refrigerants.

Internal Distribution The Direct Expansion distribution

tube is designed to distribute the gas evenly to provide

optimum performance and operating stability. The

thermal expansion valve may need a slight adjustment

to obtain proper operation, with 5F (-15C) to 10F

(-12C) Superheat. For optimum performance, do not

oversize the expansion valve and, where practical, do

not install elbows between the expansion valve and the

refrigerant inlet.

Performance Hints Direct Expansion at various

temperature ranges:

- 10F (-23C) to 50F (10C) suction

No oil return problems.

< -10F (-23C) suction

Possible oil return problems depending upon gas

velocities; install oil separator or other method of

oil return.

Piping Refrigerant inlet piping should be sized to

100 fpm (0.50 m/s) or greater velocity, liquid refrigerant.

Condensers:GEA PHE Systems Brazed Plate Heat Exchangers are

applicable for all types of halocarbon refrigerants.

Ammonia:GEA PHE Systems Brazed Plate Heat Exchangers

are applicable for Ammonia applications with

Nickel-Chrome Brazed Alloy. Please consult the

factory, Applications Engineering, for correct model.

Insulation:Recommend to insulation for all evaporators

and subcoolers to prevent sweating. For temperatures

below -20F (-29C) consult the factory.
