ACT

The ACT PREMIUM range of refrigeration dryers provides high performance and operational continuity even under extreme conditions. The ACT range has low pressure drops due to the ALU-DRY exchanger and is efficient due to the latest generation of compressors. It has a +3°C dew point, which is maintained even when operating conditions change using the three-way stainless steel hot gas by-pass valve. The range is designed to meet the most demanding applications up to a 300 m3/min. flow rate. The range standard electronic controllers are equipped with an RS485 port for connectivity to the company’s management system (INDUSTRY 4.0 ready). Water-cooled version on demand from ACT55. Non-wasteful capacitive drains are standard from ACT180 and optional for lower models.
