Description
ZEKS 21000HSGM MultiPlex Tru-Cycling Refrigerated Dryer
The ZEKS 21000HSGM is a MultiPlex™ large-capacity cycling refrigerated dryer designed for high-flow compressed air systems. It is listed in the ZEKS price book as part of the MultiPlex™ Large Capacity Cycling (HSGM) platform with a flow range of 3,600–24,000 SCFM.
Standard equipment for the MultiPlex platform includes a sequencer that balances operation with uniform runtimes across modules (with inlet/outlet air pressure and temperature readouts), multi-disconnects for isolating each module during maintenance, internal filtration with pressure drop monitoring and an element replacement alarm, and Savair™ zero air loss demand drains with isolation valves and a liquid level switch that reports drain malfunction to the controller.
Key Features
- HeatSink™ cycling operation: cycles refrigeration to reduce energy use during lighter demand.
- CFX® exchanger technology: designed for efficient heat transfer and low pressure drop.
- Capacity: rated for 21000 SCFM (see rating conditions).

Benefits
- Protects downstream equipment: helps reduce moisture-related corrosion and contamination.
- Improves system reliability: supports consistent air quality for tools, controls, and processes.
- Supports efficiency at part load: cycling operation can reduce run time when demand drops.
- Right-sized capacity: 21000 SCFM (see rating conditions) helps match system demand when applied at rating conditions.
Installation & Application Notes
- Confirm inlet pressure, inlet temperature, and ambient conditions align with the dryer rating basis for the series.
- Verify system demand does not exceed 21000 SCFM (see rating conditions) at the rating conditions.
- Allow clearance for service access and condensate drain routing during installation.
ZEKS 21000HSGM MultiPlex Tru-Cycling Refrigerated Dryer is a strong fit when your system requirements match the listed capacity, pressure rating, and electrical configuration.
Frequently Asked Questions
ZEKS 21000HSGM MultiPlex Tru-Cycling Refrigerated Dryer
▶️ Question: What is the rated capacity for this model?
Answer: This model is rated for 21000 SCFM (see rating conditions) under the series rating conditions.
▶️ Question: What does a refrigerated air dryer do?
Answer: It cools compressed air to condense water vapor, then removes the condensate to help reduce moisture in the air system.
▶️ Question: What should I confirm before installation?
Answer: Confirm connection size, pressure rating, and electrical requirements match your system.
▶️ Question: What electrical information do I need to check?
Answer: Verify voltage, phase, and frequency match the unit nameplate before installation.
▶️ Question: What routine maintenance is typical?
Answer: Keep condenser surfaces clean, verify condensate drains operate correctly, and replace air filtration elements on schedule. It also lists footprint 252 x 100.75 x 106.53.
