The TLV25, general

The Tamson model TLV25, low temperature viscometer bath is designed to perform a variety of accurate temperature controls for e.g. low temperature viscosity measurements. The TLV25 system contains a 25 liter Dewar flask. The fluid in the flask must permanently be cooled by an external cryostat. The temperature set point is maintained via a microprocessor controlled heating element.

Depending on the type of cryostat used, minimum end temperatures of minus 30°, -60°C or -80°C can be reached. Temperatures are measured in 25 liters of Methanol with the KV40 and KV80 cryostats. At these minimum temperatures still enough energy is provided to maintain stable temperature when glas work is placed in the bath. The system accuracy conforms to ASTM D445 and ISO 3103 description. The bath is inside illuminated by a fluorescent light build-in behind the Dewar flask. The cryostat is a separate apparatus and must have enough capacity to cool 25 ltrs of liquid. It is further important that the cooling power supplied by the cryostat is very stable. It is for these reasons that we strongly recommend a combination of the TLV25 with the KV40 or KV80. Span Depending on the used cryostat:

- Minus 30°C with KV40

- Minus 60°C with KV80

- Minus 80°C with KV80S - Lower temperatures on request Accuracy

The set point can be set in steps of 0,1°C

from - 90°C up to plus 70°C. Overall

system accuracy is better than ±0,04°C. Read-out is on a 4 digit, 7 segment LED

display in 0.1 °C. On request read-oud

also is available in °F. Safety thermostat To prevent problems caused by a malfunctioning of the heating element the bath is equiped with a safety thermostat. This thermostat can not be adjusted, and

has a fixed preset value of 125°C. When for any reason the temperature of the bath will raise to this limit



the safety thermostat will cut the mains supply Circulation pumping device The bath is equipped with a special stirrer-pump combination which ensures a good uniformity. Condensation prevention To prevent build up of condesat onto the cold surface of the window, surface heaters have been installed around the window. A temperature sensor on the window keeps the surface temperature of the window just above the dew-point

under ambient conditions of up to 40 °C and 85% RH. Illumination An illuminator providing diffused fluorescent light for background lighting is mounted on the roar of the bath. It can be switched on and off with the switch-lamp on the control panel. Top plate The bath is supplied with a round lid with 3 holes 50 mm diameter to accept 3 capillary type viscometers in holders. Behind each viscometer position there is an opaque glass plate for easy reading of viscometer.

Installation

Tamson baths are carefully packed when they leave the factory to avoid damage during transport. Check the packing for any external damage and make a note on the shipping documents if any damage is found. Always retain the cartons and packing material until the bath has been tested and found in good condition, because transport companies generally will not honour a claim for damages if the respective box(es) is (are) not available for examination. - Clean inner bath thoroughly of any loose packing materials etc. - Place the bath in a level position. - Check operating voltage (230 V or 115 V) and connect the bath to appropriate mains supply. The bath has to be filled with a liquid suitable for operating temperature. WARNING: Never operate the bath without fluid !!!!

Filling and Bath liquids

Fill the bath up to 5 -10 mm below the lid. At no time should the bath level be allowed to fall 60 mm of the top plate. Depending on the bath temperature we advise the use of methanol as bath fluid.

Use a mains supply that is well earthened and clean of interferens and can carry

the load of the bath. Be sure to check the power requirements (230V / 115V)

marked on the tag plate at the back side of the bath.

When using a Cryostat KV80 or KV40, the use of the mixture water

and ethyleneglycol is not recommended because of the high capacity of the cooler.

(ice will grow on the evaporator causing poor heat exchange and unstable

temperature control )



Cooling

Low temperatures are reached with the use of a cryostat (immersion cooler). The top-plate of the bath provides a hole of 50 mm diameter to accept the evaporator of the immersion cooler. To reach temperature stability which conforms ASTM D445 only use the KV40 or KV80 as cryostat.

Heating

To reduce temperature fluctuations the cryostat provides stable cooling. To settle the bath temperature at a fixed set point a microprocessor controlled stainless steel heater regulates the temperature.

Operation The front panel layout shows following 4 operating keys:

Page List Down Up

The “Page” Key offers following:

• Temperature readout in °C,

• Temperature set point in °C, value between –90 and +60°C, • Tuning the bath (“Atune”), • Changing the tuning (PID) parameters, • The ”List” Key will list the P, I, D, High Cutback and Low Cutback options, • Changing the temperature calibration offset,

• Programming the bath(ACCS). *This menu item has only been build in for servicing purpose and should not be used by users.

Up and Down keys allow changing the listed value. All changed values like set point and PID parameters will be kept in memory even after switching of the power supply. Quick start To start operating the bath in a quick way do following:

• Fill the bath with fluid until the level reaches 10 to 20 mm under the top plate,

• Place the power plug,

• Place cold finger/cryostat,

• Switch the bath on with the mains switch,

• Choose a working temperature (set point) with and ,

• Switch on the cryostat.

• Wait until the bath has reached its set point and choose ATUNE by pressing ,

• Now press and the display shows ”tune”,

• Press to choose “ON”,

• Press and together, the display will now alternate the values “tune” and the actual temperature,

• After a short period, depending on the set point temperature, the blinking of “tune” will stop and the bath

is ready for use.



What is tuning The temperature control of the bath is based on a digital PID system. Due to the use of different fluids in the bath with their own heat capacity, the use of external cooling and external connected processes(circulation), the PID parameters have to be optimized after changes to the system. Tuning of the bath results in:

• Stable temperature control of the bath,

• No over- or undershoot of the temperature set point,

• Quick response to deviations from the set point caused by external disturbances. Tuning can be done automatically or manually. The Parameters mentioned in Table 1 will influence the control of the bath.

Parameter Description Display Proportional band The bandwith in display-units over which the output power is

proportional between minimum and maximum Pb

Integration time Determines the time taken by the controller to remove stady state error signals

Ti

Derivative time Determines the time taken by the controller to react on error signals.

Td

Low cutback The number of degrees below set point at which the controller will cutback the output power in order to prevent overshoot on heat up.

Lcb

High cutback The number of degrees above set point at which the controller will cutback the output power in order to prevent undershoot on

cool down, important when working below 20°C.

Hcb

Relative offset Offset only shown for PD, or P control (I = off). [degrees] rES

Automatic tuning

• Chose desired set point,

• Wait until the bath has reached the set point temperature,

• Choose with key Atune,

• Press key option “Tune”,

• Choose with key “on”,

• Press key and simultaneous, the display will show alternating the word “tune”.

The controller will shortly oscillate the temperature in the bath and from the reaction of the bath it will calculate the “P”, “I” and “D” parameter. It will store these parameters and returns to its controlling function. The bath will show its actual temperature on the display. The tuning parameters are kept in memory after

power has been shut off. The time needed for auto tuning the system depends mainly on the cool-down time of the bath. Due to thermo dynamic law the tuning time behaves like an exponential function of the bath temperature. Auto tuning should in all cases give you an optimal result. There are cases in which you want to tune by hand and set the PID parameters yourself. Following will describe how to manage that.

• Choose set point temperature,

• Wait until the bath has reached its set point temperature,

• Choose key to show PID,

• Press for Ti or Td parameter,

• Change the value or press enough times so that the display shows “Off”,

• Choose with Atune,

• Press to show “Tune”,

• Press for “on”,

• Press and to confirm tuning and display will alternate “tune” and bath temperature,

If PI or P control has been chosen, the reached end temperature in the bath will always deviate from the set point temperature. To eliminate this error, the value off the error has to be appointed to the rES parameter in the PID menu. This parameter will only be visible when P or PI control is activated. To eliminate the error offset do following:

• Choose PID with ,

• Press for rES,

Tip. To allow optimal temperature control of the bath fluid, the bath has to be tunded

after following changes:

- Other type of fluid used in the bath,

- Change of fluid level

- Setoint which deviates more than 5°°°° of previous tuning set point,



• Adjust value to eliminate offset with and ,

• Press and at the same time to confirm and show bath temperature reading.

Manual tuning The parameters for the PID control can also be changed manually. Again this procedure is only to be followed when automatic tuning is not functioning. PID parameters can be accessed by pressing:

• Key for 3 times, display shows “PID”,

• Key , display shows PD which is the proportional value,

• Change PD value with and ,

• Key , display shows Ti which is the integrator value in seconds,

• Change Ti value with and ,

• Key , display shows Td which is derivate value in seconds,

• Change Td value with and ,

• Key , display shows Lcb,

• Do not change “auto” value,

• Key , display shows Hcb,

• Press and at the same time to confirm and show bath temperature reading.

The control also allows to set the I and D values to zero. The bath will then function as a proportional system. The “P” parameter can than be varied to an optimal value by trial and error. A higher P will stabilize the system when I and D are off. The PID parameters can also be determined with the use of the Ziegler Nichols method described below. Manual tuning by Ziegler-Nichols With the process at its normal running temperature: 1 Set the integral time “Ti” and the derivate Time “Td” to off 2 Check if the Lcb and Hcb are set to auto 3 Ignore the fact that the temperature may not settle precisely at the set point 4 If the temperature is stable, reduce the proportional band Pb so that the temperature just starts to

oscillate. If the temperature is already oscillating, increase the proportional band until it starts oscillating. Allow enough time between each adjustment for the loop to stabilize. Make a note of the proportional band value “B” and the period of oscillation “T” Set the Pb, Ti and Td parameter values according to the calculations given in the table below

Setting the cutback values The above procedure sets up the parameters for optimum stady state control, If unacceptable levels of overshoot or undershoot occur during start-up for large step changes in temperature, then manually set the cutback parameters Lcb and Hcb. Set the low and high cutback values to three times the proportional bandwith (That is to say, Lcb = Hcb = 3 * Pb) See the examples in drawing 2 and 3 for over- and undershoot. Drawing 2 Drawing 3

Faultfinding

The motor is not running and the lamps are not on. Check the main voltage and all electrical connections, including switches.

Mechanical over temperature cut-out +70 °C is de-activated and can be reset by pressing the reset button on the back panel near the power supply cable. Mechanical max. current protection ( 16A ) is de-activated. This fuse is located on the back panel of the TLV25 Motor is not running, lamps and electronics operate and the motor turns freely by hand. Motor fuse has deactivated motor. Reset fuse by pushing button on panel. Motor overloaded. The motor protection may trip because of mechanical overloading of the pump. The 7 µF capacitor is faulty. Replace motor capacitor located behind the front panel. Loose connection is possible. Check wiring at rear of motor cover. Minimum temperature is not reached There are three possible causes: 1) The KV80 is defective 2) There is a lot of ice forming around the KV80 probe 3) The methanol used is very poluted with water due to condensat and ice forming Ad 1)The KV80 can only be tested on performance when the TLV25 is completely free of ice and the methanol used is fresch. The cooling down period of the KV80/TLV25 combination is indicated in the manual see chapter “The TLV25, general”, page 7.

If the minimum temperature is not reached the filling of the refrigerant inside the KV80 is not ok. The unit should be repaired. This is a tecnical proces only specialized companies can perform. Ad 2+3) Free all ice from the TLV25 and KVprobe and hose. Let the unit dry in ambient and make sure there is no moisture absorbed in the tubing of the KV80. The combination KV80/TLV25 needs good maintenance. Refresh the methanol in teh TLV25. It's preferred to keep the unit in a moisture free environment and prevent ice from growing on the machine. Regularly remove ice if neccessary.

R.C. van Hall Director



Cryostat, Installation and use

Put the unit in its proper place. Leave enough room around the cryostat for sufficient air circulation. Place the unit in a clean working environment and keep away from dust. When air can not circulate well the cryostat will overheat itself resulting in irreversible and severe mechanical damage. Dust will block the condensor and might also cause overheating of the system. Overheating will cause severe damage to the compressor. The cold finger can be placed in the TLV25 holder, next to the three opening lids for the viscosity meter holders. When the TLV25 is fully filled with methanol the cryostat can be switched on. In all cases water is not recommended to use in combination with a cryostat. Water will freeze very quick around the cooling coil preventing proper energy exchange between the cold finger and the bath fluid. It is possible to cool down other processes with the cold finger i.e. rapidly lower temperature in hot fluids. It is

not recommended to permanently cool fluids with a temperature above 80°C. Pressure inside the evaporator circuit will be extremely high and can causing severe thermal damage to the compressor. Regularly check:

The apparatus to see if airflow is not blocked around apparatus, Apparatus and condensor are free from dust, Hose is not mechanically damaged.

Cryostat fails to operate Check if apparatus is switched on and power is on mains. Check mains fuse. The KV40 has no fuse build in, the KV80 has a fuse on the front panel next to the power switch.

• Fan does not function Check wiring inside apparatus and see if nothing is blocking the fan

• Ventilator makes noise Open apparatus and check blocking of the fan. After several years bearings can be worn out. replace fan.

• Ice forming on cold finger Water vapour in the air condensates on the top of the cold finger. In time this ice will grow, forming a block of ice. Turning of the cryostat and let the ice melt, or prevent air from forming condensate by insulating the cold finger.

• Bad cooling due to forming of ice (crystals). Do not use water or water glycerine mixture as a bath medium. Instead use methanol.

It is advised not to move the refrigeration hose at low temperatures. Only move the

apparatus and hose when switched off and cold finger at room temperature.

KV40 Cryostat

The KV40 is designed for cooling down fluid in viscometer baths. The combination of the KV40 and our low temperature viscosity measurement bath TLV25, allows stable viscosity measurements at temperatures with a

minimum of minus 30°C. To work at different temperatures, a microprocessor controlled heating element inside the TLV25 system heats the fluid against the constant cooling capacity of the KV40 cryostat.

Stable regulation of the KV40 / TLV25 combination is guaranteed for all working temperatures with a minimum of approximately 2 degrees above the combinations’ minimum temperature. This minimum temperature of –32’C is reached when the TLV25-heating is fully off. The cooling probe of the system is formed by a stainless steel coil at the top of a flexible hose. This probe can be immersed in the cooling fluid. The KV40 - cooling power is measured in a Dewar flask containing 10 litres of methanol. All measured values are based on a TLV25 system filled with 25 litres methanol.

The KV-system is guaranteed CFK/HCFK free.

Using the KV for other cooling purposes The KV40 can also be used to provide cooling power in a specific process. Examples are cooling down liquids more rapidly or lower temperature of a specific process. The cold finger can be used for this purpose as a “cold spot”. In fluids the finger can be immersed or the finger can be mounted just to cool down gas in a process.

It is important not to continuously heat the cold finger. Immersing the finger in fluids of over 100°C for a period over more than 2 hours will harm the compressor. The pressure of the cooling gas inside the finger will raise dramatically due to these high temperatures. This raise in pressure causes the compressor to work harder and heat up. Overheating on the long term can overheat and severely damage the cold finger on the long term.

KV80 Cryostat

The KV80 is designed to cool down fluids. The combination of the KV80 and our low temperature viscosity measurement bath TLV25, allows very stable viscosity measurements at low temperatures. To work at different temperatures, a microprocessor controlled heating element inside the TLV25 system heats the fluid against the constant cooling capacity of the KV80 cryostat. Stable regulation of the KV80 / TLV25 combination is guaranteed for all working temperatures with a minimum of approximately 2 degrees above the combinations minimum temperature. This minimum temperature is reached when the

heating from the is TLV25 fully off and lies around minus 65°C. The cooling probe of the system is formed by a stainless steel coil at the top of a flexible hose. This probe can be immersed in the cooling fluid. Temperatures mentioned here have been measured with methanol. The KV80 cooling capacity has been measured in a Dewar flask with 10 litres of methanol. The KV-system is guaranteed CFK/HCFK free.
