Cleaner, more comfortable, more economical air. Hi-Quality. Hi-Performance.
Hi-AQ.
Sensible and Enthalpy Heat Exchangers:
The innovative Hi-Panex product line of Sensible and Enthalpy wheels,
represent the latest development in rotary wheel heat exchanger
technology for ventilation air. Seibu Giken developed the use of
ion exchange resins in place of traditional desiccants, resulting
in the lowest co-adsorption in the industry. Ion exchange resins
attract water molecules from air without adsorbing them into pores.
This ionic attraction is highest for water due to the polar electrical
field of the water molecule. Co-adsorption of non-water vapors is
lower than silica gel, lower than 4A and even 3A molecular sieve
desiccants.
Construction:
The Hi-Panex heat exchanger 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.
Energy Savings:
Hi-Panex rotary heat exchangers use exhaust air from the building
to provide a temperature and humidity gradient to reduce the summer
cooling and winter heating load on the building system. Using the
standard indoor design condition for 75 °F at 50% relative humidity
compared to outside air conditions the Hi-Panex total enthalpy heat
exchanger removes 1.6 tons/1000 cfm of load against the ARI outdoor
standard of 95°F dry bulb and 75 °F wet bulb (.0142 W) and
3 tons/1000 cfm of load rated against the more "humid climate"
condition of 95°F dry bulb and 80 °F wet bulb (.019 W).
Heat Recovery and Dehumidification:
Superior preformance makes the Hi-Panex enthalpy heat exchanger
the first choice for pretreatment of ventilation air. SG America
offers thermally reactivated desiccant dehumidifiers to handle the
rest of the load, even to maintain positive humidity control within
the building. Our desiccant dehumidifiers further dry a portion
of the ventilation air to a low dew point temperature, such that
when mixed with the return air, the main cooling coils become "sensible"
only. This eliminates wet condensate pans, increases the efficiency
of the chiller and provides for lower humidity throughout the supply
air distribution system.
Features:
- Wheels and cassettes available for air flows from 1,000 to 50,000
Scfm.
- Available for factory manufactured air handlers, contractor
built-up systems, ERV OEMs and packaged systems.
- Reduces carryover of air pollutants including odors
- Produces clean ventilation air through energy saving and environmentally
safe technology.
- High efficiency sensible and latent heat exchange
- Enthalpy wheels are anti-bacterial - mold and mildew proof
Applications:
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.
