OEMs know: Looking towards the future, engineering processes will demand improved uses of technology. Optimization is needed – with solutions that combine top performance, environmental friendliness and maximum cost efficiency. Our Green Series technology meets the demand.

Partially Recessed

For space restricted installations, ideal for door mounting. One cutout size for models of different capacities.

Easy Installation and Maintenance

Tool-free spring plate design keeps the unit safely in place and allows mounting by 1 person in less than 3 minutes with 55% lower mounting costs. Direct access to the PCB and the fans means 80% shorter repair times.

Environmentally Friendlier

The redesigned refrigeration circuit uses up to 58% less refrigerant (R134a) reducing the risk of greenhouse gas emissions.

Thermal Overload Protection

Compressor and fan motors are outfitted with integral temperature switches to shut down the unit in the event of excessive temperature.

Pressure Overload Protection

High pressure cutout switch ensures safety by shutting off the compressor in the event of excessive pressure appearing in the refrigeration circuit.

Closed Loop Design

Designed to isolate the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet.

Thermal Expansion Valve

Regulates the flow of refrigerant based on thermal demand for efficient performance over the entire operating temperature range.

Efficient Circulation

Large distance between intake and exhaust vents for efficient air circulation and elimination of hot spots.

UL Listed

Listed to the new UL 60335 certification with enhanced safety standards.

Improved Energy Efficiency

The redesigned system achieves energy consumption reductions of up to 11%.

Energy Savings Mode

When cooling isn’t necessary due to equipment shutdown or cold weather conditions, the unit conserves energy by turning fans off – except for periodic cycling for circulating air within the enclosure.

Maintenance Free, Filterless Design

The wide fin spacing is less susceptible to clogging from dirt buildup which can cause the unit to work harder and hamper efficiency.

External Display

For visual temperature monitoring.

High Airflow Backward Curve Impeller Fan

Provides high airflow in a long lasting, single bearing design. Outperforms typical two-bearing blowers with nearly twice the lifespan.

Hermetically Sealed Compressor

The absence of any refrigerant fill valves eliminates leak paths. Recharging is never needed. 100% cooling capacity efficiency is ensured.

Active Condensate Management

Condensation is a natural byproduct of refrigeration. The heated condensate collection pan boils this off thereby eliminating the need for drain tubes and buckets. To conserve power, this heater only activates when necessary.
