Cooling for plastics machine controls

4 April 2007 Enclosures, Racks, Cabinets & Panel Products

Elen Enclosures can offer a number of maintenance-free solutions for the plastics industry.

The Pucel-Nano series of nano-coated, filter-less cooling units and air-to-water heat exchangers have been used throughout Europe on machine control panels to solve overheating problems and to minimise expensive down-time and material wastage. Of special interest here are the LW air-to-water heat exchangers which use chilled water (which is normally available for the cooling of moulds on injection machines) as cooling medium. This is a very efficient and economical way of control panel cooling.

The internal (cold) and external (warm) side are completely separated with the warm side cooling cartridge covered with a special coating that repels dust, liquid droplets and fibres. There are no filters to change or clean. This also applies for the LK-Series electrically operated, compressor type refrigeration cooling units.

In critical applications where the space is limited and cooling is vital to the operation of the machine, the Fandis TCU-Series of thermoelectric (Peltier) panel coolers can be used.

Where clean and dry compressed air is available, the most economical and totally maintenance-free solution to cooling is the use of the Arizona V-Series of Vortex cabinet coolers and Vortex tubes which are very compact and have no moving parts. The Vortex tube works by splitting a stream of compressed air into a cold and hot fraction.
