True-Cycling is not just a catchy phrase, it is the way the HeatSinkTM dryers operate. ZEKS has taken the customer's requirements for tight dew point control, rugged reliability, and low operating cost, and designed the world's most advanced cycling refrigerated air dryers. The ZEKS True-Cycling dryer is THE STANDARD by which all dryers are measured.

Common manufacturing practices, process machinery cycling, and changing production requirements result in variable compressed air volume use. This, combined with lower ambient and inlet air temperatures, results in a reduced load on the dryer. ZEKS pioneered the design of a dryer that includes a refrigeration system in conjunction with a thermal mass that efficiently stores cold energy. This allows the refrigeration compressor to cycle OFF during periods of reduced load while the dryer continues to remove moisture and contaminants from the air stream. The refrigeration system in a non-cycling dryer operates continuously which greatly increases its operating cost compared to a True-Cycling dryer.

True-Cycling operation enables HeatSink air dryers to provide significant energy savings when compared to non-cycling dryers. Air treatment cost is not wasted through continuous operation of the dryer refrigeration system as it is with non-cycling dryers. Changes in compressed air consumption resulting from variable shift and process demands as well as daily and seasonal fluctuations in ambient temperature provide tremendous energy saving opportunities. In many applications installation of a HeatSink dryer can save as much as 80% of the operating cost of a non-cycling dryer.

Best-In-Class

ZEKS patented CFX^© stainless steel Corrugated, Folded heat eXchangers have been engineered exclusively for compressed air drying to include a high heat transfer coefficient and industry-leading low pressure drop. A multi-path flow area that is 3-5 times that of the equivalent copper tube exchanger, combined with continuous self-cleaning action, minimizes fouling potential. Corrosion resistant 304L stainless steel is used in all air circuit exchangers. CFX^© provides durability in environments where copper or other metals are not suitable.

• 100% Stainless Steel Construction
• Less Prone To Fouling Than Copper Or Aluminum Exchangers
• Flow Area That Is 3-5 Times That Of Competitive Exchangers Industry-Leading Low Pressure Drop
• Higher Energy Efficiency Than That Of Competitive Exchangers
• ZEKS Exclusive 10-Year Warranty

The unique CFX^© design has allowed ZEKS to provide air treatment with an extremely low pressure drop. This minimizes the overall compressed air energy requirement and the need for greater air compressor capacity.

Refrigeration system components are sized to handle the maximum moisture loading for each HeatSink^TM model. Condensers have been selected to maintain efficiency in all environments and they are positioned to avoid accumulation of dust and debris. High quality fully hermetic compressor life is maximized because of cycling dryer operation. Refrigeration lines include valves for convenient maintenance.

The 75-2,400 scfm HeatSinkTM models include a CFX^© stainless steel precooler/reheater that enhances the efficiency of the dryer and optimally conditions the air for use. Compressed air is warmed to approximate ambient temperature to eliminate pipe sweating.

Internal structural pieces are heavy gauge galvanized steel. Full cabinet is powder-coated with removeable panels for convenient access to all internal components.
