Coldstore services

Coldstore, aka cold room, aka coldroom, freezer-room, fundamental installation on busy catering sites and shops. There are many makes and models available, but only a few are of decent quality, to add site-specific problems, lack of maintenance and installation mishaps, issues are quick to occur and to be of a repetitive nature. Common problems:

a) Gas leakage- due to a loose pipework and vibration gas leaks will occur and lead to a system failure.

pipe damage
Deep internals of the True 4 door pizza counter refrigerator, left to the evaporator: Low-pressure pipe wall has an oval opening on the horizontal stretch, created by the friction of capillary line (smaller diameter pipe). Very bad location for any welding work but is fixable.

 

 

 

 

 

 

 

b) Compressor trouble-all sorts of electrical and mechanical problems like metal fatigue, excessive wear and tear, premature wear and tear, overheating, loss of hermetics of the compressor housing, broken windings, snapped terminals,  live to live shorts, live to ground shorts,  and other similar surprises often start with small gas leaks.

c) Water leakage – both inside and out of the cold store.

c) Control circuit problems- electrical diagrams tend to get lost over the time, if so, whoever gets your callout has to reinvent this circuit, then understand if and what has been bypassed or hardwired as a “FIX” by previous service engineers and then go pinpoint the faulty part of the circuit and finally if there is any way to make it work? Even temporarily?

Two types of cold stores exist: Modular and Custom Built.

Pros, modular cold rooms are easy to erect. Everything should be built in, once you installed it, its plug and play. Refrigeration engineer is not required unless you need to commission the job for warranty reasons. Not expensive in comparison to other options.

Cons: Set footprint, sometimes complicated to service as may be assembled very tight, heat load and compressor noise is rejected within proximity unless external heat dumper is installed. Equipment specific parts like motherboards, tanks, bushings, pipes and clips are pretty expensive and sometimes hard to find.

Custom built: Need to take good care when designing and building, don’t forget the base heating and defrost system. Pros: maximise your floorplan, compressor noise outside, heat rejected outside. Costly. Labour extensive, Electrician and refrigeration engineer required.

Commercial refrigerators and freezer can develop many types of the electrical faults from loose terminals to short to the ground compressors.
