The Premier Manual Defrost Freezers with Natural Refrigerants take a large step forward in performance from past solid door manual defrost units. These units feature a digital microprocessor temperature controller allowing for the precise temperature management necessary for critical samples and supplies.

The all-new temperature display and alarm module offers 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.

Environmentally friendly, natural hydrocarbon (HC) refrigerants which vastly reduce global-warming potential while meeting new EPA/SNAP mandates.

Premier Manual Defrost Freezes with Natural Refrigerants 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.
