The Tek-Temp LK-10/NHR/VA/R1 is a light-capacity air-cooled chiller designed for precise temperature control in industrial and laboratory applications. This unit delivers 2500 BTU/hr (733 watts) of cooling capacity at 20°C and maintains temperature stability to ±0.5°C (±0.1°C with optional PID microprocessor controller). The 2.5-gallon stainless steel reservoir, CFC-free refrigeration system, and hot gas discharge bypass eliminate compressor cycling while ensuring process stability. Ideal for applications demanding stable thermal regulation without tap water consumption.
