m anufacturer has all the information required to make a system match, such as cooling conditions, and heat loads, a compatible system yielding an adequate cooling capacity can be specified directl y to the customer or contractor. This direct link b etween consumer and manufacturer promotes a strong relationship between the supplier and the end user, ensuring the cold room will work as intended, cooling the produce within to increase its lifespan and preventing spoiling.

A nother key advantage is that technical

information and details of spare components are a ll available from the same place. Having the c onvenience of being able to resolve an issue or enquiry over the phone with a single point of contact saves both time and resources, as well as decreasing the likelihood of confusion that c ould arise from trying to mix-match a cold room s ystem. Receiving accurate information from t he manufacturer can also help to pinpoint any potential issues before they arise, or can help identify faulty components for which they can provide spares information directly, promptly resolving the issue.

Warranties will also be much more quickly resolved. For example, a compressor fault can be caused by a fault elsewhere in the system such

as lack of superheat at the evaporator. If the system was supplied by a single m anufacturer, a much stronger claim c an be made than would otherwise be possible with a system supplied by separate manufactures.

It can be quite difficult to find cold room e vaporators and refrigerated condensing u nits from the same manufacturer, as m any distributors often only stock the m ost popular brands and frequently these brands will only offer one part of the system. Marstair has recently launched its cold room evaporator range to supplement its range of r efrigerated condensing units, enabling easier access to cold room systems from a single

m anufacturer. Alongside these new introductions, technical information is provided for complete system matches to enable easy selection. This is reinforced by a three-year parts only warranty that is available via the web portal, providing the i nstallation details are filled out correctly. I believe this is only the beginning of a trend towards using cold room systems from a single manufacturer. Further reductions in the refrigerant GWP quota within the F-Gas regulations mean that new lower GWP

refrigerants will be required, and the next generation of low GWP refrigerants lie in the mildly flammable category of A2L. These newer A2L refrigerants are beginning to enter the market, but complexity within the regulations for u sing these new refrigerants makes it much more sensible that the system is supplied through one manufacturer.

To conclude, the requirement of cold room split refrigeration systems is here to stay and dealing with a sole manufacturer of a cold room system w ill become more prominent. It already makes sense from a system compatibility and warranty point of view, but when A2L refrigerants become the norm, it will be a much more logical choice from a compliance point of view as well.
