Q.What is the difference between an integral and a remote refrigeration system?

A. An integral system means it is a stand alone unit, with everything it needs to work built in.  It's quick, convenient and compact. Just plug in and go. 

A remote system has the compressor, fan and other "hot, noisy bits" located away from the storage cabinet or cold room and are connected by pipes.  A remote system resembles central heating in reverse - instead of heating radiators, insulated pipes carry the heat away from the cabinets and disperse it out the back.  This means it's quieter and cooler in operation at the point where it normally counts, more efficient and usually cheaper to run too.  However, it can be more complex to install and will need specialist engineers.
