THP – Outstanding quality

Why is it necessary to dry compressed air?
The atmospheric air drawn into a compressor is a mixture of gases that always contains water vapour. The amount of water vapour air can carry varies and is mostly dependent on temperature. As air temperature rises – which occurs during compression – the air’s capacity to hold moisture increases also. When the air is cooled, its ability to hold moisture reduces, which causes the water vapour to condense. This condensate is then removed in the downstream centrifugal separator or the air receiver. Even then, the air is often still totally saturated with water vapour. This is why, as the air cools further, significant amounts of condensate can accumulate in the air distribution piping and at take-off points. Therefore, additional drying is essential to avoid production downtime and interruptions, as well as reduce costly maintenance and repair work. Refrigeration drying is usually the most efficient solution for the majority of compressed air applications.

The refrigeration dryers in THP series units feature powerful cooling systems. These include a high quality refrigerant compressor, generously-dimensioned heat exchanger surfaces, as well as cleverly designed cooling air flow. This combination therefore ensures dependable operation even at high temperatures and guarantees stable pressure dew points at all times.

The smaller the pressure differential within a dryer, the more efficient its performance. All THP dryers operate with exceptionally low pressure differential values thanks to quality, flow-optimised stainless steel piping.

The 45 bar THP series dryer is equipped as standard with a high pressure version of the ECO DRAIN 12 condensate drain. This ensures even more efficient condensate removal without any pressure loss and also saves energy. The electronic condensate drain is optionally available for the 50 bar models.
