Versatile Heat Recovery

 N/A Gardner Denver™ utilizes heat recovery systems to maximize efficiency by recovering energy generated during compressed air production.
  • As much as 90% of all energy used can be recovered and utilized.
  • Thermostatic control maintains desired temperature in the compressor.
  • Heat exchangers are available in different materials for difficult conditions.
  • Cooling water circuit can be designed specifically to customers needs.

Heat Recovery Systems

 N/A Gardner Denver™ offers a wide range of heat recovery systems to meet your application needs :
EWNA
Gardner Denver™'s standard water cooling system
  • An after cooler and oil cooler connected in series as a standard.
EANA
Standard air-cooled compressor with separate air module
  • All ducts required for efficient heat recovery and utilization are easy to arrange.
  • Flexible air module placement, 1 m from the compressor or further with an additional pump.
The PRE system
Designed for water-cooled compressors
  • Cooling water is initially directed through the after-cooler and then it absorbs thermal energy from a large oil/water heat exchanger.
The DIR System
Ideal for closed systems with inlet water temperatures up to +50 ºC
  • Separate water-cooling supply is required for the after-cooler.
The +W System
  • Heat recovery system for air-cooled compressors.
  • Transfers the heat produced in compression into water.
