Project Description

Works conducted at M&S Wigan, consisted of a new Food hall scheme, incorporating new chilled & frozen food cases. In addition a new IP Alarm network was installed, using an RDM Front End PC and Data Manager, plus a full gas leak detection system was connected to the refrigeration alarm network for remote monitory.

The refrigeration system utilised R744 (CO2) as the refrigerant. Both HT and LT remote cases in the sales area were fed by the remote CO2 plant.

The cold room suite installed comprised of a chiller and a freezer cold room. The evaporators for the chiller cold room were split between the HT CO2 DX system and a R449A condensing unit to achieve the required diversity.
