The Tek-Temp RK-19 is a rack-mountable, air-cooled chiller engineered for precision temperature control of coolants in industrial and laboratory environments. Delivering 2500 BTU/hr (733 watts) of cooling capacity at 20°C, the unit maintains coolant temperatures between 5 and 35°C with ±0.5°C stability as standard—tightened to ±0.1°C via optional configuration. The CFC-free refrigeration system uses R134A refrigerant with hot gas bypass for enhanced control stability.
