The HRM-V Split Passive Heat Pipes Series is designed for projects where supply and exhaust air streams cannot be placed close together. Ideal for layouts requiring complete isolation to prevent cross contamination, it offers higher effectiveness and better efficiency than water run-around systems—without moving parts.
Coilmaster’s HRM-V Split Passive Heat Pipes system uses multiple charged circuits, with two rows of heat exchangers, a vapor header at the top, and a liquid header at the bottom. A permanent elevational difference between supply and exhaust air streams enables optimized recovery for the season that yields the most BTUs, while still allowing partial recovery in the off-season.
Liquid-side control valves on each circuit allow recovery to be turned off during economizer conditions or closed to prevent frost in extreme cold.
For balanced recovery in both heating and cooling, HRM-V units can also be equipped with a Dynamic Seasonal Offset (DSO™) system, delivering about 45% effectiveness on a six-row system at 500 FPM. This system outperforms older side-by-side configurations by 20–35%, with higher sensible effectiveness and improved seasonal efficiency.
