coldchainThe Coldchain transport refrigeration unit is a modular system consisting of separate condenser, evaporator and vehicle driven rotary compressor. The condenser section is a pressed steel construction, zinc passivated and powder coated giving a smooth finish and excellent durability. The evaporator section is fabricated from aluminium and galvanised steel ant contains only stainless steel hardware.

The integral design of the condenser and evaporator is such that both bulkhead or roof mounted fixing may be accommodated, but also the unique facility of being able to install the condenser into moulded roof sections whilst allowing total accessibility to all electrical and refrigeration components.

As referred to in the options section a range of compressor adaptor kits are available to choose from to complement your Coldchain package.
