Due to an increase in business, and in turn higher door usage between production and chilled storage, our client needed help maintain critical temperatures by cooling the corridor that links production to various chill stores.
Stonegrove installed 2-off 20kW Danfoss condensing units and 3-off dual discharge evaporators 10kW each (electric defrost). The system is set to +5c air on, ET -5/+35. The refrigerant charge is R449a - which we are finding offers good energy efficiency.
The control panel comes complete with LED display / controls for room temperatures, with RDM control feeding off the corridor units.
