CPZ Dryer
Refrigerant Air DryerCP CPZ Refrigerant Dryer — Dry Compressed Air for Every Factory
At 20°C ambient, a compressor that delivers 200 litres of air per second also introduces approximately 240 litres of water per day into your compressed air system. This moisture causes corrosion in pipework and tools, damages pneumatic valves and cylinders, and contaminates products. The CPZ Refrigerant Dryer removes this moisture before it reaches your factory's pipework.
The Chicago Pneumatic CPZ Refrigerant Dryer uses a high-efficiency 3-in-1 aluminium heat exchanger to cool compressed air to its dew point, condense and drain moisture, and re-heat the dry air before it enters distribution pipework. The result: compressed air at a stable Pressure Dew Point (PDP) of 7–10°C — suitable for the vast majority of industrial applications.
As the Authorised Chicago Pneumatic Dealer in Vapi GIDC and South Gujarat, R R Enterprise supplies the complete CPZ dryer range (CPZ 30 to CPZ 2650) along with CP filters, automatic drains and oil-water separators for a complete compressed air quality solution. We also provide monsoon pre-season dryer service — critical for South Gujarat's 90%+ humidity monsoon months when dryer performance is most heavily loaded.
How the CPZ Dryer Removes Moisture — 3-in-1 Heat Exchanger
The CPZ dryer's 3-in-1 aluminium heat exchanger combines all three functions in a single compact unit. The Hot Gas Bypass valve regulates refrigerant flow to maintain a stable PDP and prevent condensate freezing.
1. Cool & Condense
Hot saturated compressed air enters the Air-to-Air heat exchanger, where it is pre-cooled. Then the Air-to-Refrigerant exchanger cools it to the dew point — water vapour condenses into liquid.
2. Collect & Drain
The Water Separator collects the condensed water from the cooled air flow. The Automatic Drain removes the liquid condensate — keeping the system free of accumulated water.
3. Re-heat & Deliver
The dried air is re-heated in the Air-to-Air heat exchanger before exiting. This prevents condensation on the factory's cold pipework — dry air delivered at near-ambient temperature.

Common Questions — CPZ Refrigerant Dryer
Everything you need to know about the Chicago Pneumatic CPZ dryer range in Vapi.
A compressor that delivers 200 litres of air per second also supplies approximately 240 litres of water per day when working with air at 20°C. This moisture causes corrosion in pipework and tools, damages pneumatic valves and cylinders, contaminates products in food and pharmaceutical applications, and causes production interruptions. The CPZ Refrigerant Dryer removes this moisture before it reaches your factory's distribution pipework.
The CPZ dryer achieves a Pressure Dew Point (PDP) of 7–10°C. This corresponds to ISO 8573-1 Class 4–5 for water content — suitable for the vast majority of industrial compressed air applications including pharmaceutical instrument air, chemical process air, food packaging and pneumatic tools. For lower PDP requirements, an adsorption dryer is required instead of or in addition to the refrigerant dryer.
The CPZ dryer's high efficiency plate-fin heat exchanger delivers 50% less energy consumption compared to conventional shell-and-tube type dryers. The optimized refrigeration system, Hot Gas Bypass valve and 3-in-1 heat exchanger design minimise compressor running time while maintaining consistent PDP.
18 models from CPZ 30 (1,000 l/min / 35 CFM) to CPZ 2650 (75,000 l/min / 2,650 CFM). Models CPZ 30–870 operate on single phase 230V/50Hz. Models CPZ 1270–2650 require three phase 400V/50Hz. Maximum operating pressure: 13 bar for CPZ 30–870 and 10 bar for CPZ 1270–2650.
Yes. R R Enterprise AMC for CPZ dryers includes scheduled condenser cleaning, PDP measurement, automatic drain testing, refrigerant charge verification and a written service report, plus a dedicated pre-monsoon service visit (May–June).
