Adsorption dryer Heatless HL
 |
Why drying compressed air?
Compressed air is used in almost all areas of industrial manufacturing as a source of energy or processing.
Compressed air needs to be dry, oilfree and clean in order to prevent costly production downtimes and losses in the production quality. The atmospheric air drawn in contains harmful substances, dirt particles and moisture in the form of water vapour, which condenses in compressed air pipes and can lead to considerable damages (corrosion, freezing etc.).
Ultrafilter HeatLess HL adsorptionn dryers
As a complete system the HeatLess HL adsorption dryer has a prefilter (with automatic condensate drain), silencers and an integrated dust filter onboard providing maximum efficiency and operational safety. HeatLess HL adsorption dryer are produced for a wide range of applications and are delivered ready to connect and easy to install.
With 12 sizes for volume flows from 50 to 1000 m³/h and pressure dew points of -20 °C, -40 °C or -70°C customized solutions are offered. While matching perfectly to compressors requirements, no over-sizing is necessary. The demand for regeneration air remains constant.

Compact design
Due to the compact design the new series of HL dryers are saving installation space and shipping costs. The symmetric design with the central position of the UPEC control system are service- and maintenance friendly. Service components are easy to maintain, because they are accessible from the front side of the dryer. Pre- and afterfilters are also installed in central position, easy to access from both side (no preferred flow direction). The modular system design allows to modify a HeatLess HL dryer to an OFA oif free air system or to an ALG air breathing system (seeoptions).
Qualiy product
Only the best components were used for the production of the ultralter high-efciency compressed air dryers. According to our quality safety program in appliance to DIN ISO 9001 these products are declared „quality product“. Together with the maintenance- and user-friendly construction, absolute operation safety and reliability is ensured, guaranteed by a 5-years-operation warranty. Therefore products of these performance are marked „Made in Germany“. All ultrafilter HeatLess HL adsorption dryers guarantee lowest possible total cost of ownership.
