ZEKS line of alternate cooling source compressed air dryers utilizes an available ammonia, chilled water or glycol supply for drying compressed air. The units are manufactured without a dedicated refrigeration compressor or condenser, as the cooling source is provided and processed by your central facility.

ZEKS CDA Alternate Cooling Source Dryers Overview

•	No electrical connection required
•	Protects compressed air processes – removes moistures, aerosols and other contaminants
•	Consumes no additional power – uses available cooling source: ammonia, water or glycol
•	Very low pressure drop – maintains compressed air system efficiency
•	Stainless-steel CFX® exchangers – durable and corrosion resistant in all applications
•	Complete condensate removal – efficient separation from airstream and discharge through no air loss drain
•	Simple installation – requires only compressed air and cooling source connection
•	500-19,200 scfm capacities

Standard Features
•	Pneumatically operated demand drain – for reliable condensate discharge
•	Precooler/reheater – conditions air optimally before entering the compressed air piping
•	No more than 3 psi pressure drop at full load (± .5 psi)
•	Carbon-steel air piping, headers and separator
•	Compressed air pressure and temperature gauges

Optional Features
•	100% stainless-steel air circuit
•	Alternate drain configurations

ZEKS Ammonia Chiller Dryers (CDAN)

CDAN dryers uses nominal 150 psig ammonia that is expanded through the dryer exchanger. These models require a back-pressure regulator for the ammonia circuit that is available as an installed option.

Standard Features
•	Carbon-steel components - for the compressed air and ammonia circuits
•	Carbon-steel ammonia lines, headers and thermostatic expansion valve(s)
•	Ammonia suction pressure gauge

Optional Features
•	100% stainless-steel ammonia circuit
•	Compressed air outlet pressure gauge
•	Compressed air outlet temperature gauge
•	Ammonia discharge pressure gauge
•	Back-pressure regulator

ZEKS Water Chiller Dryers (CDAW)

CDAW dryers use chilled water or glycol and yield a compressed air dew point that is approximately 5°-7°F higher than the inlet water or glycol temperature. Flow control valves must be furnished by the user as well as shut-off valves, if desired, for the cooling source.

Standard Features
•	Copper water lines and headers and carbon-steel air piping, headers and condensate separator
•	100% non-ferrous water circuit
•	Inlet water temperature gauge

Optional Features
•	Outlet water temperature gauge
•	Inlet water pressure gauge
•	Outlet water pressure gauge
