Recirculating Chiller Requirements
The TIM Testers require a recirculating chiller for coolant flow with sufficient temperature stability and flow rate for optimal test results.
Recommended Chiller Specifications
- Flow Rate: 2.0 gal/min (8 liter/min) positive displacement pump
- Typical pressure: 60 psi (340 kPa)
- Temperature Control Stability: +/- 0.1°C @ min. 500W (TIM 1300) or min. 800W (TIM 1400)
- Set Point Range (minimum): 10°C - 35°C
Any chiller that fits these technical requirements can be used although a chiller that is controllable via serial communication port is most convenient. WinTIM software uses the serial control link to turn the chiller ON/OFF and to change the chiller setpoints. When using a chiller that is not equipped with serial control capability, WinTIM displays screen-prompts for the operator to perform these ON/OFF and setpoint changes manually. Although WinTIM minimizes the need for chiller setpoint changes when testing to the ASTM 5470 sample average-temperature of 50°C some level of inconvenience will be experienced under manual chiller control depending on the test specifications selected. .
WinTIM software supports serial-equipped Thermo-Fisher and Lytron chillers with serial command tables that are embedded in WinTIM software. The following chillers all provide these serial control features and are recommended:
