the most economical drying method for any system

Refrigeration dryers

  1. 1
    Refrigeration dryers
    are used in compressed air systems worldwide and represent the current state of technology. Refrigeration drying is the most cost-effective technology for the drying of compressed air: The compressed air is cooled, so that water vapour in the air condensates inside the unit and can be drained off. For fluctuating volume flows, we recommend the DRYPOINT RA eco, as its intelligent controls enables you to make significant energy savings. For applications where stable conditions are a key requirement, the standard DRYPOINT RA direct expansion dryer is the most efficient solution.
  2. 2
    Tried and tested, utilised everywhere: DRYPOINT® RA
    The DRYPOINT RA refrigeration dryer is the standard solution and therefore always the first choice for applications with stable operating conditions and constant pressure dew points of + 3°C. The large variety of models enable us to always be able to provide you with the correct solution for your requirements. Every one of them impresses with reliable drying, minimal compressed air loss as well as low energy consumption, even with varying work load. The tried and tested design of the DRYPOINT RA enables not only maximum functionality, but also reliable, safe and cost-effective operation.
  3. 3
    Convincingly efficient with minimal pressure loss
    A high pressure drop in the refrigeration dryer must be compensated for by an increased compressor performance and the therefore associated additional energy demand. The consequences are unnecessary energy consumption and significantly higher operating costs. In the case of DRYPOINT RA refrigeration dryers, the pressure drop has therefore been reduced to an absolute minimum. The essential elements here are the flow-optimised heat exchanger, a demister for safe separation and generously dimensioned components, which ensure a low pressure drop of 0.16 bar on average – in full load operation.
