Heat pipes for heat recovery

The heat energy in waste air is valuable. With a heat pipe, you can recover most of it for free. Changing the air in occupied buildings has an expensive side-effect: the heat energy that you pumped into the building escapes with the air and the fresh air that replaces it has to be heated afresh.

Wherever air is mechanically supplied and removed, there’s an opportunity to install an energy-saving heat pipe. The principle is simple: the heat pipe extracts heat from the waste air stream and adds it to the incoming stream. The effectiveness of this process can be as high as 75%, yet the running costs are virtually nil and the set-up costs are minimal.

SPC has undertaken a research program in conjunction with Brunel University with the aim of providing a novel manufacturing solution. The development is now complete, resulting in the latest version of SPC heat pipes being available at commercial prices and relying on water rather than refrigerant as their working fluid.

The technology developed by SPC is the subject of a worldwide patent, covering the newly developed manufacturing technique.

Refrigerant charged heat pipes have been successfully used for many years and provide significant energy saving benefits to all projects in which they have been incorporated.

Typical environments include swimming pools, HVAC, drying processes, paint-spray booths, laundries, kitchens etc. What’s more, a heat pipe can be treated to withstand corrosive environments with no loss of effectiveness.
