TDG has invested more than £1 million in a cooling plant at its temperature controlled depot in Newport.
The company says the move represents the beginnings of a national strategic investment in response to new regulations.
The new system uses less energy than the previous air-cooled condensers.
The new “Star Ammonia” system uses evaporating condensers and floating head technology. The evaporators’ motors have increased fin spacing at the rear of the coil block.
It uses motor inverters and PLC (Telstar) controllers to optimise the compressors and improve co efficiency of performance.
It also uses a combination of screw and reciprocating compressors to achieve best performance ratios during off cycling.
Ian Newell, regional manager at TDG said: “As well as reduced energy costs, this cold store will have some of the most accurate temperature gradients available. Temperatures are constant across whole chambers, and we have managed to equalise the temperatures so we have no peaks or troughs anywhere within the temperature controlled storage area”.
