The Premier Compact Laboratory Refrigerators are purpose-built for scientific and medical applications. To improve performance, the Premier Compact Laboratory Refrigerators feature a digital microprocessor temperature controller allowing for the precise temperature management necessary for critical samples and supplies. The standard temperature display and alarm module offer product security with a monitoring and alarm system. Real-time sample simulated temperatures are constantly displayed and supported by audible/visual high and low-temperature alarms. Remote alarm dry contacts and an access port are provided to simplify connections to existing facility monitoring systems. A forced air directional refrigeration system provides superior temperature uniformity and recovery after door openings. An automatic cycle-defrost design prevents product damaging temperature spikes. Freestanding models require 4” of clearance around back and sides of the unit for proper ventilation. Improper installation will void the warranty and will lead to temperature maintenance issues, overheating and possible failure. *Environmentally friendly, natural hydrocarbon (HC) refrigerants which vastly reduce global-warming potential while meeting new EPA/SNAP mandates
