The TKD-200/H Series Heater-Chillers have been designed with maximum feature-packed flexibility in mind.

With its unique modular construction, the TKD-200/H Chillers offer an extensive selection of control, monitoring, alarm, communication, and interlock options.

In addition, water or air-cooled condensers, extended temperature range equipment, and all-stainless steel and polymeric circulation systems are available.

These units, used for heating and cooling applications, are suitable for external temperature control. Powerful circulating pumps and high heating and cooling capacities guarantee short heat-up and cool-down times. The TKD-200/H Series will provide dependable temperature control for a wide variety of laboratory and process heating and cooling applications.

Featuring CFC-free refrigeration systems with compressor hot discharge gas bypass. Stability to ±0.1°C is maintained with our microprocessor-based temperature controller, featuring digital display of process and setpoint temperatures.

All TKD-200/H Series systems come standard with a coolant pressure gauge and a coolant level switch. Also standard is a flow/pressure adjustment value (these features are often optional with other manufacturers). The TKD-200/250 Series Chillers are ideal for both OEM and end user applications.
