A refrigerated trailer, also known as a ‘reefer’, is usually a box van trailer, but with a refrigeration unit fitted to it, in addition to it’s body having special insulating properties. However, a curtainsider may also be refrigerated and is referred to as an ’insuliner’.
Refrigerated trailers can be single temperature controlled, when only one temperature is required at any one time, or multi temperature controlled, having different ‘compartments’ to enable cargo that requires different temperatures to be transported together. Goods can be transported as frozen or as chilled.
They are typically loaded / un-loaded via its rear doors, either at a loading bay or by using a tail-lift at the delivery location. Refrigerated trailers often have temperature recording and monitoring equipment to help manage the temperatures that the cargo is kept at.
Refrigerated trailers are available as single deck trailers and double deck trailers (also known as double decker trailers), the latter often with a ‘step-frame’ design, which together with the increased height, enables additional cargo to be carried. Double deck trailers can have their ‘second’ deck as a fixed deck or as a lifting deck that can be lowered and raised to load and un-load the cargo.
Refrigerated trailers are manufactured in the UK by Gray & Adams and Cartwright. Overseas manufacturers such as Schmitz Cargobull and Krone also offer a refrigerated range of trailers.
