Heat Pipe Technologies

Heat PipeAll heat pipe technologies provided by Venmar CES are AHRI Certified to Standard 1060 and subsequently bear the seal for participation in the AHRI Air-to-Air Energy Recovery Ventilation Equipment Program based on AHRI Standard 1060.

Performance is maximized by perfectly balancing the refrigerant charge (typically R-134a for most commercial applications) versus the tube diameter, internal capillary wick structure and the integral aluminum fins, to maximize the heat transfer effectiveness of the closed loop evaporation/condensation cycle required for energy recovery to occur.

Heat pipe technology offers one of the most robust solutions for difficult applications where high temperatures are encountered, low Exhaust Air Transfer Ratio (EATR) is required or corrosive and contaminated air may be encountered with a high risk of fouling. Heat pipes may also be configured as a pre-cooler, re-heater for enhanced dehumidification in its standard form or in a “wrap-around” configuration. Heat pipes can also benefit from a number of performance enhancement strategies such as tilt packages, direct and/or indirect evaporative cooling.

Venmar CES heat pipes are sensible only devices and provide the following benefits:

  • Good sensible effectiveness
  • No moving parts
  • Compact at large volumetric flow rates
  • Extremely low maintenance and extremely easy to clean
  • Can act as a pre-cooler, re-heater in series with a cooling coil in a “wrap-around” configuration for enhanced dehumidification
  • Able to withstand high temperatures and differential pressures up to 10-inches
  • Certified to AHRI Standard 1060

Heat pipes can be found in our full custom DOAS EnergyPack® systems.
