Advanced heat exchanger technology

offers significant energy and cost savings anywhere you use warm or hot fluids in your operations. Power-Pipe® Drain Water Heat Recovery (DWHR) Systems enable manufacturers and processors to decrease energy costs and to reduce their operation's environmental impact by using energy far more efficiently. The patented and patent-pending Power-Pipe DWHR System reclaims and recycles a substantial portion of the heat energy (generally 90% of the heat and associated energy costs) that is typically lost in waste fluid in most industrial processes and operations.

Major applications include:

  • Pulp and paper
  • Brewing
  • Parts washing
  • Food processing
  • Dairy production
  • Textiles
  • Meat packing
  • Baking
  • Automotive Industry 
  • ANY APPLICATION where a substantial quantity of  hot fluid is disposed of
The potential for energy and cost savings is often very large in industrial applications because of the large volume of heated fluids consumed. The Power-Pipe can recover up to 70% of waste fluid heat and use it to preheat fluids before they enter a primary water heater.

The Power-Pipe DWHR System consists of multiple coils of copper tube wrapped together around a central copper drainpipe. This double-walled heat exchanger efficiently recovers heat energy from waste fluid and reuses it to heat cooler incoming fluid.

Technically known as a falling film heat exchanger, the Power-Pipe is based on a fundamental physical principle called the "falling film" effect. Fluid falling down a vertical drain stack does not run down the middle of that stack, but instead clings to its inside wall. This creates a thin "falling film" from which the all-copper Power-Pipe can readily recover heat energy.

The Power-Pipe's energy and cost savings potential is easily realized in a wide range of applications, recovering heat energy from sources such as coolants, condensates and hot process waters.

Power-Pipe Systems are non-clogging, maintenance-free and scalable for use in large flow and low flow applications. They are UL listed and safe for use in potable water applications, such as food processing. In addition, Power-Pipe Systems can be easily coated for use in hostile and corrosive environments.

The Power-Pipe's performance has been verified by Natural Resources Canada, the University of Waterloo, as well as other American and Canadian agencies and power companies, in independent third-party testing.

Power-Pipe Systems are backed by full technical support. This free support includes energy savings studies, feasibility analyses, system design consultations, CAD drawing elements, and installation support.

Power-Pipe Systems are simple, effective, and foolproof. They are a proven way to save energy and money with no downside risk, considering an expected service life of more than 50 years.
