Recover up to 75% of the heat energy from extracted air
|
|
|
|
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 nil and the set-up costs are minimal.

Energy-efficient industrial processes
|
|
|
|
Industrial processes are huge consumers of energy. Much of that energy escapes with waste gases and liquids.
A heat pipe can recover and recycle that heat without fear of contamination from the waste product itself.
|
|
|
|
What's more, a heat pipe can be treated to withstand corrosive environments with minimal loss of effectiveness.
Typical environments include swimming pools, HVAC, drying processes, paint-spray booths, laundries, kitchens etc.

A heat pipe beats all other solutions
|
|
|
|
A heat pipe is not the only method of heat recovery – but it is the best.
|
|
|
|
Run-around coils may be inexpensive, but they require a pump pack and expansion tank
to operate. In cold climates, they must be charged with anti-freeze to prevent frost
damage. However, where the intake and discharge air streams are far apart, a run-around
coil is easily the best solution.
|
|
|
|
Plate-to-plate heat exchangers are effective, but bulky.
They are also expensive and difficult to clean; the trapped condensate encourages mould growth.
|
|
|
|
Heat recovery wheels require intensive maintenance, they're
prone to cross-contamination, and they do not drain condensation effectively.
