Heat Of Compression (HOC) Dryers

CICB manufactures heat of compression (HOC) dryers in collaboration with M/s Henderson Engineering Company, Inc., of USA. Henderson designed and patented the HOC dryers way back in 1970s. Heat of compression dryers find application in virtually every industry. Compressed air has to be dried to the required levels to protect the instruments from getting damaged. The dryer must be capable of delivering low dew points consistently without any dewpoint spikes. Henderson?s ?Sahara? series HOC dryers provide the right solutions to the compressed air drying needs. The dryer design fully uses all of the normally wasted energy from compressor to regenerate the desiccant. The patented design also avoids the use of external heater thus reducing the operating cost of the dryer. The purge air loss is negligible compared to 15-20% as in the case of conventional heatless dryers. Following are the other salient features of Henderson HOC dryers: use of 2-way, high performance butterfly valves with no leakage; reliable drain trap ? this consists of two separate traps ? a primary and secondary; if the primary (mechanical) trap fails, the secondary (electronic) trap automatically activates thus preventing the moisture from entering the desiccant; and use of dew point demand system (DPDS) saves operating cost. With the use of DPDS, tower shift takes place based on the dew point of outlet air rather than being controlled by a timer. With this, the life of desiccant gets extended. The company manufactures a wide range of HOC dryers from 100 scfm to 25000 scfm capacity.
