Industrial Drying Rooms & Ovens

The challenge

Drying rooms and ovens exhaust large volumes of hot, humid air. That stream carries most of the energy you paid for straight out of the stack, while fresh make-up air has to be heated from ambient. It is the single most common source of avoidable energy cost in coating, printing and drying plants.

How Qingli solves it

• Finned tube radiators and steam coils heat supply air efficiently.
• Waste heat recovery heat exchangers transfer heat from exhaust air to incoming fresh air or process water, cutting heater load.
• Custom coil geometry handles dusty or humid exhaust without excessive pressure drop or rapid fouling.

Recommended product types

• Boiler Economizer & Waste Heat Recovery Unit
• Finned Tube Radiator
• Air Heat Exchanger (Steam Coil)

What we need from you

Exhaust air volume and temperature, humidity or solvent content, target supply air temperature and available installation space. Our selection software turns these into a sized heat recovery proposal.

Typical result

Lower heater fuel or steam consumption, more stable drying temperature, and a short project payback on lines running multiple shifts.
