HOC Adsorption Dryer Gardner Denver

HOC Adsorption Dryer

The HOC adsorption dryer Gardner Denver is an efficient compressed air treatment solution designed for industrial operations that need to reduce energy costs, eliminate air losses, and ensure automatic, reliable operation, even in continuous and demanding applications.

What is an HOC adsorption dryer?

An adsorption dryer with heat of compression is an industrial adsorption dryer that reuses the heat generated by the compressor itself to regenerate the desiccant, reducing electrical consumption and overall operating costs.

HOC dryer for compressed air

The HOC dryer for compressed air delivers reliable compressed air without the need for an electric heater, making the drying process more efficient and economical.

Industrial air dryer for continuous operation

Designed as an industrial air dryer, the Gardner Denver HOC dryer is ideal for plants operating 24/7 that require stable, dry air supply.

How does the Gardner Denver HOC dryer work?

Heat of compression without electric heater

The system operates as a dryer without electric heater, using energy already available in the compression process and achieving practical energy cost reduction.

Zero Purge Technology

Zero Purge Technology allows the dryer to operate as a no air‑loss dryer, eliminating purge air and reducing energy consumption and OPEX.

Automatic and stable operation

With fully automatic operation, the dryer requires minimal maintenance intervention and delivers consistent performance over time.
