No-Sweat Cabinet

Testequity uses a combination of structural foam and fiberglass blanket insulation for a higher combined R-factor than just fiberglass alone. The door sealing surface is kept warm by circulating excess heat from the refrigeration system. The result is a cabinet that does not sweat due to condensation during low temperature operation.

The window is constructed of 6 panes of tempered glass separated by low-conductivity spacers to keep thermal losses to a minimum. Our unique design virtually eliminates exterior window sweating during normal temperature cycling conditions.

The stainless-steel interior liner is heliarc welded, while the refrigeration compartment behind the liner is double-insulated and carefully sealed. These design features reduce thermal losses and prevent moisture migration, ensuring years of optimum performance while keeping the cabinet rust-free.

Reliability & Safety That's Designed In

Non-CFC refrigerants are used in a cascade (two compressors) configuration. Expansion valves provide optimum performance throughout the operating range. Pressure regulators keep the operating pressures within safe limits regardless of load conditions. Liquid injection ensures cool compressor operation during high-temperature pull down for long life. Sequential starting of each compressor reduces the current demand on start-up. Each compressor is protected by high/low pressure switches. Care has been taken to use a minimum number of fittings, joints and welds to reduce the possibility of refrigerant leaks.

All electrical control components are UL approved. Each branch circuit is individually protected with class-CC fuses. A main power disconnect switch is provided on the front panel. The nichrome air-heater has a low watt-density and even heat distribution for reliable performance and fast response. A fusible link provides fail-safe protection against thermal runaways, in addition to the microprocessor-based high/low limit controller.

The side and rear panels are removable to permit complete access to the refrigeration system for ease of service and preventive maintenance. Shown above with the optional circular chart recorder, which mounts conveniently in the front.
