-40°C dewpoint

Offered in three flow capacities, the HPD range of 'point of use' dryers from Hi-line Industries are compact, cost effective and feature a 'minimum downtime' cartridge change. They are suitable for remote installations, or wherever there may be only limited access available.

They provide generalised protection for downstream airline production equipment, as well as many specialised requirements, including instrument air quality, printing and gas analysing devices, and so on. The HPD unit provides a localised installation where high quality air is a critical requirement. It ensures a low dewpoint (-40°C) at point of use, or where an existing air supply has only been dried to a refrigerant air dryer quality of +3°C dewpoint.

The dryer range uses a disposable desiccant adsorption cartridge to effectively remove moisture from a compressed air supply. The special housing design lets the cartridge be changed within 2min, without the need for any specialised tools. A pressure dewpoint of -40°C can be achieved with no energy consumption, no power required and no air loss from the use of purged air.
