Cain Industries Exhaust Heat Recovery Systems

20-100% of every combustion fuel dollar spent is wasted by means of heat exhaust. The great news is 30-50% of this energy loss can be recovered! Cain Industries reclaims lost heat and transfers its precious BTUs back into your water, glycol, special fluids and steam processes. The following applications would greatly benefit from a Cain heat recovery system:

Combustion SourceWasted $$ for every
fuel dollar spent
Industrial Hot Water or Steam Boilers$ .20
Commercial Hot Water or Steam Boilers$ .30
Dryers$ .30
Reciprocating Gas Engines$ .35
Diesel Engines$ .35
Ovens$ .40
Furnaces$ .80
Catalytic Converters$1.00

Fast Payback
The words "safely and economically recover waste heat" equate to "no-risk return on investment (ROI)", which is exactly what Cain Industries heat recovery systems provide. By installing a fuel-saving Cain economizer on a combustion source, the BTUs recovered usually pay for the equipment within 12 to 24 months (annual ROI of 50-100%). Reclaiming 30-50% of the wasted energy for every fuel dollar spent. The exact payback period for your installation will depend on local fuel costs and the hours of combustion operations.

Depending on fuel type, temperatures, flow size requirements, performance and specification, Cain Industries can propose a specific cost effective exchanger to economize your fuel bills. Listed below are just a few design features which clearly speak for themselves and far exceed the capabilities of other economizer manufacturers:
  • Internal, stainless steel, exhaust bypass for stack corrosion control, tempering exit temperatures, and/or protection against exhaust back pressure buildup due to fouling.
  • Stainless steel hinged access doors for ease of routine inspection and/or cleaning.
  • Quick release, adjustable tension latches requiring no tools, which lock the access doors in place.
  • Three types of available fin tube materials:
    1. TP316 stainless steel tube and AL-FUSE™ fin metallurgically bonded.
    2. SA178 carbon steel tube and fin, Nickel Braze/welded or standard frequency welded.
    3. TP316 stainless steel tube and TP304 stainless steel fin, Nickel Braze/welded or standard frequency welded.
  • No weld/removable tubes with no pressure welds in the gas stream, for easy tube replacement.
  • Round or rectangular design configurations as standard model selections.
  • Custom computer design for special multiple order OEM requirements.
  • ASME & National Board designed and certified by Cain Industries.

Optional Components
Depending on the application, Cain Industries offers a variety of ancillary equipment, such as timed automatic sootblowers, factory insulation, circulating pumps, thermometers, remote indicating controllers, modulating damper actuators, and stack-to-economizer transitions, to meet the needs of each specific installation.
