Walk in Chillstore in Bury
Walk in Chillstore – As part of their expansion plans our client a manufacturer of food testing products based in Bury, instructed ICE Ltd to design and build a walk in chillstore enclosure and refrigeration system to maintain the room at 5°C.
The work comprised of the construction of the new insulated chillstore enclosure, including all insulated walls, doors and ceiling, together with all flashings, fixings and sealants.
The room measuring 7.2m x 5.7m x 5.1m (width x deep x high) was built on the existing concrete floor with 100mm PIR (Polyisocyanurate) to walls , 125mm PIR (Polyisocyanurate) to ceilings and finished in white foodsafe P.V.C coated galvanised steel to all seen areas.
To access the room we installed a manual sliding door with a clear opening of 1.9mm wide with a height of 2.7m high to allow access for a fork lift truck. The door slides on Fermod 3500 series track and has lever handles fitted inside and out.
To serve this enclosure we designed a single refrigeration system to maintain the room at a set point of 5°C.
The refrigeration system operates on R449A refrigerant, utilising a fully housed packaged condensing unit and ceiling mounted evaporator cooler.
The condensing unit is positioned externally at floor level at the rear of the building and is from the Danfoss Optyma Slim range containing a Danfoss scroll compressor, integral condenser fan, filter drier, sight glass and automatic safety controls.
The evaporator coolers are of copper tube/aluminium fin construction and manufactured by Searle. Defrosting of the evaporators and drip trays is via electrical defrost heaters installed within the coolers.
The evaporator cooler is installed at high level at the end of the room and supported from hangers fixed to the structure of the building.
All refrigeration pipework is supported using standard insulated pipe clamps with all suction lines insulated using fire retardant Armaflex.
All electrical control cabling is run on cable tray above the enclosure, before descending down to the cooler.
Drains from the cooler are ran in white plastic pipe to the outside of the building.
A bespoke IP65 control panel was installed to serve the system housing a ID985LX Eliwell controller along with all breakers, contactors, and run/fault lamps are installed at the front of the enclosure.
