A Fairfax full-size refrigerated semi-trailer is typically a 15.1m long, fully-insulated quad-axle unit designed for operation at minus 28C and can have multi-temperature capabilities.
Tare weight of a complete semi-trailer is around 10,500kg subject to fridge selection and spec details. The rear axle is a ‘Castor-steer’ to reduce tyre scuffing and allow a tighter turning circle to be achieved. The trailer can also have double stacking systems incorporated into the side walls, giving loadings of up to 56 pallets. Refrigeration is often a multi-temperature unit with a remote evaporator at rear. The body can be divided into one, two, or three temperature sections.
Other designs are also manufactured with a choice of 2, 3 or 4 axles, varying overall wall construction and lengths up to 15.65m HPMV permitted semi-trailers.
