Heat Pipes (HPT)

Download Brochure

Heat pipes have been used successfully in a variety of HVAC design applications over the past 27 years for passive dehumidification ranging from 2 ton residential units to 230 ton commercial applications. HPT has Wrap-Around heat pipes and Heat Recovery systems.

The DHP Series (Dehumidifier Heat Pipes)

U-Frame Dehumidifier Heat Pipe™ (DHP) also known as Wrap Around Heat Pipe consist of two sections, the precool (evaporator) section placed before the cooling coil and the reheat (condenser) section placed after the cooling coil or wrapped around the cooling coils of  AHU’s / FAHU’s to save energy and increase the moisture removal capacity of Air Conditioning systems.
It allows the cooling coil to meet the dew point faster and with greater efficiency. Condensate removal by the cooling coil is greatly enhanced, often doubled by the heat pipes.
DHP saves energy by reducing Sensible Heat Ratio (SHR) and by replacing or minimizing expensive reheat of Air Conditioning Units.

Benefits

  • Free precool & reheat.
  • Increases latent capacity without additional energy consumption.
  • Dehumidification & superior Indoor Air Quality (IAQ).
  • Prevents odors caused by moisture (mold growth).
  • Low airside pressure drop.
  • No moving parts, no pumps or any other mechanical devices to break down or wear out.
  • Operates without interference of existing circuiting.
  • Often allow downsizing of entire Air Conditioning system.
  • May replace electric strip reheat.
  • Less operational costs / quick payback on investment.

Dehumidifier Heat Pipe (DHP)

  • Available for 500 to 100,000 cfm systems.
  • High quality Copper Tubes for reliability & longevity.
  • Aluminum or Copper Fins.
  • 8 to 14 fpi spacing.
  • Standard & Custom dimensions.
  • Corrosion / Anti-Fungal protective coatings (Heresite or Bronz-Glow Coatings)
  • Galvanized or Stainless Steel Casing.
  • ASHRAE Safety Group A1, HFC heat transfer fluid.

The HRM Series (Energy Recovery Heat Pipes)

Energy Recovery Heat Pipes (HRM) are passive, compact and highly efficient heat transfer device, it is used to recover energy from exhaust air to pre-cool or pre-heat outside air in comfort applications without the risk or cross contamination.

No energy input is required to operate the Heat Pipes.  When two air streams pass through the Heat Pipes, (one air stream at one end, and another air stream at the other end), the temperature difference between the two air streams activates the Heat Pipes and causes them to exchange heat by “Heat Pipe action”.  Heat Pipe action is a much more powerful heat transfer mechanism than convection flow.  Heat Pipe action utilizes the heat capacity available when the working fluid changes phases, from a liquid to a vapor and back again.

Benefits

  • Pre-cool or Re-heat incoming ambient air.
  • Zero cross contamination between supply & exhaust air stream.
  • Increases latent capacity without additional energy consumption.
  • Low airside pressure drop.
  • No moving parts, no pumps or any other mechanical devices to break down or wear out.
  • Operates without interference of existing circuiting.
  • Often allow downsizing of entire Air Conditioning system.
  • Less operational costs / quick payback on investment.

Heat Recovery Module (HRM)

  • Available for 500 to 50,000 cfm systems.
  • High quality Copper Tubes for reliability & longevity.
  • Aluminum or Copper Fins.
  • 8 to 14 fpi spacing.
  • Standard & Custom dimensions.
  • Corrosion / Anti-Fungal protective coatings (Heresite or Bronz-Glow Coatings)
  • Galvanized or Stainless Steel Casing.
  • ASHRAE Safety Group A1, HFC heat transfer fluid
