Heat-of-Compression Heater Non-Purge Desiccant Dryer (SNHH)

SNHH Series Compression Heat Non-Purge Desiccant Dryer

A model that uses the second- and third-stage heat of compression from the air compressor (about 100 °C) as the regeneration heat source, reducing electric heater power. A closed-loop circuit recirculates the regeneration air instead of venting it, cutting energy losses.

Turning wasted heat of compression into regeneration heat: SNHH

The SNHH series takes the air compressor's second- and third-stage heat of compression (about 100 °C), reheats it with a heater and uses it to regenerate the adsorption tower.

The air used for regeneration is not vented but recirculated in a closed loop, and because heat that already exists is put to use, electric heater power is reduced as well.

Key features

  • Uses the air compressor's heat of compression as the regeneration heat source

  • Reduces electric heater power

  • Closed-loop circuit for energy savings

  • Stable dew point

  • Optimal operating cost through dew point-controlled operation

Whether heat of compression can be used depends on the compressor type and piping conditions. We make a proposal after a site review.

Options

  • Modified inlet and outlet conditions (other than dew point)

  • PLC Controller & Touch Screen

  • Upper control valves (check valves as standard)

  • Alternative materials for lower and upper piping and vessels

  • Dew point-controlled operation (DPOS)

Sales inquiries

We start by reviewing whether the heat of compression from your existing compressor can be used. From design, manufacturing, installation and commissioning through to later maintenance and parts supply, GENEQ takes full responsibility.
