Determine the temperature of the coolant that the chiller should deliver
to the inlet of the process/equipment.
Find or determine the heat load that the chiller is required to remove at the temperature in step 1. This value is commonly expressed in Watts or BTU/hr. The manufacturer of the equipment to be cooled will often provide the recommended heat removal and circulating temperature. Otherwise, a basic test and calculation can be performed to determine the heat loss as follows:
where dT is the difference between the inlet and outlet coolant temperatures of your equipment. If a coolant other than water is used in this test, multiply the value obtained above by the specific heat and specific gravity of the coolant used.
Specify the flow rate requirement for the coolant, and the pressure required for continuous flow at this rate. We stock numerous circulating pump types and sizes, and our engineering staff will recommend the best pump for your application.
Determine which type of refrigerant condenser best suits your requirements.
Air Cooled condensers require only ventilation and electrical power to operate (an integral fan draws air across the condenser and dissipates heat into the ambient air). Water cooled condensers are very quiet and compact, but they require a separate source of tap or building water to remove heat from the refrigerant. For all water cooled models, we install a water flow regulating valve to ensure minimum water usage.
Tek-Temp Instruments offers dozens of options to meet your requirements. Some of the available options are:
- Multiple channel system configurations
- Coolant filtration/treatment
- Special wetted parts for coolant compatibility
- Extended temperature ranges
- Microprocessor-directed temperature and system controls
- Analog and digital remote communications
- Variety of safety switches and interlocks
These options, as well as many standard features, are detailed throughout this Website.
