Product description

The RL-61 and RL-61L adsorption dryers are powerful devices for effective air dehumidification in industrial applications. Thanks to their robust stainless steel housing, SSCR rotor and separate process and regeneration air ducting, they are ideal for long-term, demanding applications, for example in warehouses, production environments or climatically sensitive areas.

Both variants work according to the proven RECUSORB principle with integrated heat recovery, which significantly reduces energy consumption. The design allows stationary operation with maintenance access from the side and front. The models differ primarily in terms of volume flow, filter class and overall performance.

Features

Robust stainless steel housing with separate air ducts
High dehumidification performance up to 13.6 kg/h
Integrated heat recovery for energy-efficient operation
Direct-drive centrifugal fans for process and regeneration air
Two-stage adjustable regeneration heating (steam version also available as an option)
