J&E Hall extends its range of digital single scroll units

J&E Hall has updated and extended its range of digital single scroll commercial condensing units. The new V3 digital scroll condensing units, aimed at the small cold store, convenience store and restaurant markets, are now offered in four, six and eight horsepower models with improved access and features.

J&E Hall has extended its range of digital single scroll commercial condensing units.

J&E Hall Commercial Products Manager Andy Wells said: “We had some great feedback from customers about the original six horsepower units but recognised we could do more to help the installer. The extended range gives engineers greater choice when deciding on the right unit for the job. By adding two more models we are able to ensure that engineers and customers are maximising energy efficiency.”

Electronic controls optimise the operation of the units by varying the capacity with the digital compressor. Fixed speed compressor units are unable to do this but the digital compressor units allow you to match the duty required by the evaporators.

Hinged doors have been added to improve access and additional isolation valves make it easier for engineers during servicing and maintenance. The controller program has also been updated to include communication with third party controls and the addition of an optional serial card.

The units, designed for medium temperature applications, can operate with the lower GWP refrigerants R448A and R449A as well as R404A, R407A and R407F.  They are also compliant with EU Ecodesign legislation. With capacities up to 24kW and evaporation temperature ranges between -20°C and +10°C, the units are especially suitable for multi-evaporator systems.

The condensing units come fitted as standard with an oil separator for additional compressor protection and are acoustically lined for further reduced noise levels.  The Carel electronic controller is connected to an LCD interface for ease of use.  A simple manual changeover bypass function allows the units to operate in the event of an electronic controller failure.

J&E Hall also offers the digital twin scroll commercial condensing unit with a capacity up to 38kW. Offering multi-refrigerant operation similar to the digital single units, they are suitable for larger installations and are an all-in-one packaged alternative to multi compressor racks.
