This product is intended for applications where two air streams are side by side in a horizontal plane, or one air stream is right above the other with minimal distance between the air streams. It is the heat exchanger of choice in applications where cross contamination of the supply air by the exhaust air is not permissible such as labs, hospitals and other health care facilities. With no moving parts and long service life, this product is the most reliable heat exchanger in its class.

Energy recovery heat pipes from Heat Pipe Technology (HPT) provide economical and reliable recovery of both heating and cooling. This means that the payback time of your investment is minimal. HPT heat pipes are economical because of their low initial cost and minimum maintenance requirement.

For years, energy recovery heat pipes have been constructed using relatively large diameter tubes. This is because they have been single tubes that must handle vapor flowing in one direction and liquid flowing in the opposite direction simultaneously. HPT utilizes a loop circuit that allows for equal heating and cooling recovery (see HRM-H™) or optimization for either the more prominent heat or cooling recovery while still allowing for appreciable recovery the rest of the time (see HRM-Z™)

Because of HPT's unique circuit design, heating and cooling recovery can normally be accomplished without a tilt mechanism or any other seasonal changeover procedure. To make use of this unique bi-directional energy transfer feature, the air streams should be arranged side-by-side as in A and B, or with one directional energy transfer featuring over-and-under as C.

• A: Side-by-side horizontal air streams with heat pipes in a vertical plane (HRM-H™)
• B: Side-by-side horizontal air streams with heat pipes in a vertical plane optimized for heat or cool recovery (HRM-Z™)
• C: Over-and-under horizontal air streams with heat pipes in a vertical plane (HRM-O™)

Passive Operation

No energy input is required to operate the heat pipes. Heat pipe action utilizes the heat capacity available when the working fluid changes phase, from a liquid to a vapor and back again.

Durability

There is nothing in the heat pipes to wear out! The heat pipes are passive. The heat pipes are fabricated with a plurality of charged circuits. Under normal operations, there is no reason for these ever to leak. Furthermore, because the tubes in Heat Pipe Technology heat pipes are copper, leaks can be easily repaired. Most other energy recovery heat pipes are fabricated with aluminum tubes, which are difficult to repair.

Isolated Air Streams

Partitions to separate the two air streams are an integral part of Heat Pipe Technology energy recovery heat pipes. The copper tubes carrying the heat pipe working fluid are expanded into the mating holes in the partitions, assuring an excellent seal to prevent cross contamination. HPT can also provide heat exchangers with a foam-filled separation for added assurance in critical applications. HPT heat pipes are certifies ZERO EATR (Exhaust Air Transfer Rates)

Minimal Maintenance

Since the heat pipes have no moving parts, the only maintenance recommended is periodic cleaning. A coil cleaner may be applied for this purpose just as for any cooling coil.

Smallest Footprint

Energy recovery heat pipes from Heat Pipe Technology take up much less space than other energy recovery schemes. Generally, they are also considerably thinner than other heat pipes. A six-row energy recovery heat is pipes normally fabricated with a thickness of 9 inches.

AHRI Certified and ETL Listed

HPT heat pipes are performance certified to AHRI Std. 1060 and ETL listed to UL Std. 207 and CSA Std. C22.2#140.3

Why is certification and listing important:

• Third party tested and verified
• Allows for performance comparisons between manufacturers
• Designers, manufacturers and owners are assured of product performance and safety
• Help meet local and national codes
• Products are continuously tested to ensure compliance
