Heat Wheel

Dry-Save , Desiccant Dehumidifier

Operation Principles


The Hi-Panex heat wheel is manufactured by winding flat and corrugated sheets of high quality aluminum substrate to form a fluted “honeycomb" structure. The corrugated flutes provide strong support, while the interleafed flat sheets prevent nesting or collapsing of flutes. The face of the wheel is ground and polished to form a smooth surface for long seal life. Both the Sensible and Enthalpy wheels are manufactured using the same aluminum substrate and construction.

Sensible wheels transfer thermal energy only and do not adsorb moisture. Enthalpy wheels transfer both heat and moisture from one air stream to another. Ion resin is permanently bonded to the aluminum and then coated with an anti-bacterial and mold proof treatment that lasts the lifetime of the heat exchanger.
This feature allows for the use of the Hi-Panex Enthalpy wheel for pre-treatment of outside air for ventilation of buildings to improve indoor air quality. Most commercial building applications can take advantage of the Enthalpy heat exchanger while some laboratories utilize the Sensible heat recovery wheel to avoid the transfer of moisture or other vapors.

Highlights of HI-PANEX-ION ~Advanced by Ion Power~

Silica Gel has micro pores raging from 3 Angstrom to 100 A and very high adsorption capacity. Not only does it adsorb water molecules (moisture), but it also adsorbs odor molecules because of strongly hydrophilic characteristic

Molecular Sieves

Molecular sieves are crystalline metal aluminosillicates having a 3 dimensional interconnection network of silica and alumina tetrahedra.
Natural water from hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size.
Although typical molecular sieves, like molecular Sieve Type A or X, have lower adsorbability of water molecules than Silica Gel, they adsorb similar sizes of odor molecules (e.g. Ammonia).


Hi-Panex heat exchangers with Hi-moisture transfer reduces up to 80% of the humidity load of the outside air used for ventilating office buildings, schools, hospitals, nursing homes, hotels.
