Heat Pipe Technology (HPT) is now offering a “split passive” HRM-V™ with Dynamic Seasonal Offset™. HPT says its growing line of heat pipes offers economical and reliable energy recovery from building exhaust air for preheating or precooling of ventilation air. Now, the new HRM-V™ line with Dynamic Seasonal Offset™ optimizes the energy recovery performance of HVAC systems where supply and exhaust air streams are on the same level.

The HRM-V™ line supply and exhaust sections are equipped with integral, partial-face dampers and actuators on the entering side of both air-supply and air-exhaust sections of an HVAC system. Performance enhancement of the HRM-V™ line can be achieved by tuning the dampers to direct air flow through sections of the heat pipes to create an offset effect.
