Ultra-Low Temperature Freezers

Freezer has an automatic timer system that will restart the unit in case of power failure.

Frost and ice build-up along the gasket is minimized by a heater harness located beneath the channel cap away from the inner chamber.

Digital temperature control with dual display and adjustable temperature range. Scan button for setting temperature and tamper proof lockout.

Quick pull-down to operating temperature with efficient and reliable cascade refrigeration. Two large hermetic compressors ensure rapid pull-down of product load. Because of the unique design of the freezers, the pressure in the refrigeration system is held very low, eliminating excessive heat build up. This low pressure allows the freezer to operate efficiently, extending compressor life.

Compressor life is extended by an energy-saving low stage which operates only on demand.

Compressors are protected with a constant flow of refrigerant.

Heat is efficiently and effectively dissipated by an air-cooled condenser with two heavy-duty fans. Condenser requires no liquid coolant.
