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 500 SCFM at the rating conditions.
- Keep operating pressure within the unit rating (up to 300 PSIG).
- Allow clearance for service access and condensate drain routing during installation.
500 HSF ZEKS CFX® HeatSink™ Cycling Refrigerated Air Dryer is a strong fit when your system requirements match the listed capacity, pressure rating, and electrical configuration.
Frequently Asked Questions
500 HSF ZEKS CFX® HeatSink™ Cycling Refrigerated Air Dryer
▶️ Question: What is the rated capacity for this model?
Answer: This model is rated for 500 SCFM 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 are the connections and pressure rating?
Answer: It uses 3" MPT connections and is rated up to 300 PSIG.
▶️ 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 refrigerant type R404.
