MHR Series Heatless Air Dryers

75 to 3000 SCFM

 

MHR Series Heatless Air Dryers

PUREGAS MHR Series heatless regenerative air dryers are manufactured using the highest quality materials and components and will provide reliable, low dew-points to your compressed air system for many years.

The dual tower compressed air drying system utilizes ASME coded pressure vessels (100 CFM and above). The inlet air flow is controlled by 2 non-lubricated 2-way vales. The purge valves are normally closed so that if the unit depressurized or there is a power failure, the valves will close, preventing plant air pressure from being purged into the atmosphere. The outlet air is controlled by ball cone style check valves. The purge flow is exhausted through purge mufflers to reduce the air noise level to below OSHA limits. The entire system is completely pre-piped and wired on a heavy duty structural steel frame. Only air and electrical connections need to be made.
