HHL Series heatless desiccant dryers provide consistent outlet pressure dew points to -70°C.
Standard Instrumentation
- Left and right tower pressure gauges
- Purge pressure gauge
- Moisture indicator - alerts operator of elevated dew point
- The throttling valve provides accurate purge pressure adjustment.
- With inlet and outlet filters as standard
- HHL 91 – HHL 901 standard up to 16 bar
- HHL 1051 – HHL 9001 standard 10 bar (g) 16 bar on request
Controller Options
Level 1
Pure and Simple
HHL Series presents traditional heatless drying technology. Using a simple timer-based controller, these are designed to deliver maximum value to applications that operate at or near full capacity. Automatic time-controlled bed regeneration cycles offer consistent performance and economy of purchase.

1 Inlet flows are established in accordance with ISO 7183(based on 1 bar (abs) 0% of at 7 bar (g) working pressure and inlet temperature 35°C (PDP -40°) or inlet temperature 30°C PDP -70°C
2 Average Purge Flow is the total amount of air used to purge and repressurize off-stream towers averaged over the cycle time. Maximum Purge Flow is the flow rate through the off-stream tower during that portion of the cycle the purge/ repressurization valve is open.
