Lancaster, Pennsylvania – January 23, 2012. Advanced Cooling Technologies, Inc. (ACT) launches a new line of Energy Recovery/Dehumidification systems that utilize highly efficient passive heat pipe technology. ACT-HP-WA Wrap-Around dehumidification systems can be easily installed in existing or new vertical or horizontal air handlers. Direct outside air is a requirement for many new and existing buildings to increase the overall comfort and health of the building.

How does it Work?
The system is designed in a “U” shape to wrap-around the existing evaporator coil of an HVAC system. By adding a pre-cool heat pipe the system now functions more efficiently and can perform higher levels of latent cooling and increased dehumidification. Smaller capacity air conditioning systems can be designed with enhanced performance due to increased latent and sensible cooling performance.
The design pre-cools return or direct outside air prior to the evaporator coil and then re-heats the air (passively) after the coil. The result is reduced system energy/operating costs in the thousands of dollars per year. The ACT-HP-WA wrap–around design does have a small impact on static pressure but is compensated by a sizable reduction in power consumption by replacing electric or hot gas reheat.

ACT-HP-WA Wrap-Around System Advantages:

  • No moving parts or maintenance
  • Space efficient
  • Equipment capacity can be potentially reduced
  • Enhanced humidity/latent load performance improvements
  • No cross-contamination between airstreams
  • Easy to retro-fit to increase the efficiency of existing systems
  • ROI 1-3 year from saving in electrical energy

ACT-HP-WA Wrap-Around systems can be specified for existing equipment in a variety of coil configurations.  Each system is optimized for the region of installation.  Cost benefits can be projected prior to installation.  Installations from Northern States to typical high humidity Southern States can take advantage of ACT-HP-WA Wrap-Around performance. Agricultural and food processing are additional markets that can benefit from ACT-HP HVAC systems. wrap-around system can be designed with an integrated evaporator coil or fitted to your existing coil.
