Exchanger "Hi-Panex"
The development for rotary type total heat exchangers has several important improvements such as selection of the most suitable material, increasing efficiency, polishing rotor surface, increasing rotor's physical strength and prevention of rotor deflection.
As a result, total heat exchanger rotors, which are ideal and reliable, have been released as Hi-Panex series. The production machinery for honeycomb rotors such as aluminum sheet hygroscopic treatment machines, corrugation machines, winding machines, surface polishing machines and so on have also been developed and assembled by us. Therefore, any honeycomb rotors using a variety of material can be manufactured according to the customer's requirements.
Then, as adsorbent for latent heat (moisture) exchange, ion exchange resin, which adsorbs little odor, has been adopted for the first time in the world. Odor transfer and accumulation is extremely little compared with a former type using silica gel.

Hi-Panex, total heat exchanger cassette is illustrated in the above figure. Hi-Panex rotor is rotated slowly at about 16 r.p.m. in the direction of the arrow. The separator divided the rotor into the exhaust (R>EA) and the supply (OA>SA) - zones. In other words, supply and exhaust air flow alternately through the rotor in opposite direction. Almost all the total heat passing through the exhaust zone is absorbed into the rotor element. The rotor accumulated with heat is rotated half a turn to transfer the total-energy to the air of the supply zone on the other side. Thus, the outdoor air (OA) is taken to the supply air (SA) and the return air (RA) is exhausted to the exhaust air (EA) while the total heat(temperature and humidity) energy is fully transferred to the fresh outdoor air (OA). It can be said, therefore, that the function of this heat exchanger is to supply the fresh air after bringing it close to the room air condition when there is a difference in temperature and/or humidity, and thus save energy. |

| Silica Gel is no longer the best Desiccant |
||||
| Total Heat Exchanger, in which the silica gel adsorption material is firmly affixed to aluminum sheets by means of high temperature, is being conventionally unitized. In this case, at conditions of low humidity the adsorbent of the rotor element has additional adsorption capacity, and therefore adsorbs various kinds of odors. | ||||
| However, when there is a high humidity condition in contrast to the above - displacement adsorption takes place and the adsorbed odor substances are displaced with moisture in the air by means of high hydrophilic characteristic of silicagel. This is a mechanism of odor emission from silica gel when used as the adsorbent for the total heat exchanger. | ||||
| Although we have been preventing the odor problem with total heat exchangers by using a special silica gel, which relatively speaking, does not emit as much as other types, the odor problem could not be resolved. | ||||
| Since 1993, we changed our approach to the problem and commenced the
development of a new adsorbent type total heat exchanger and have succeeded
in solving the odor cross contamination problem. |

| ADDED FEATURE OF ANTI-BACTERIAL AND ANTI-MOLD EFFECTS |
||||
| Mold is not grown in the total heat exchanger by itself because its material
of the heat exchanger is completely inorganic. However, there is a possibility
that mold may be grown in the total heat exchanger due to the organic substances
flowing from the outside. |
||||
| Since we have utilized not only new adsorption material
but also anti-bacterial, anti-mold material, we have successfully countered
the odor problem and have achieved real enhancement of indoor air quality
(I.A.Q.) with this new adsorption type total heat exchanger. |

| Hygroscopict reatment for aluminum sheet | |
| First, the anticorrosive treatment is applied to the aluminum sheet. Then, the fine powder of inorganic adsorbent is strongly coated by baking without obstruction the adsorbent's "respiration". Furthermore, to prevent shedding the inorganic adsorbent powder, it is also fixed with porous coating materials. Therefore, the inorganic adsorbent can sufficiently effect adsorbent and desorption. And thus can provide the rotors with high efficiency. |  |

| This rotor is suitable for and actually used at the places such as seashore,
indoor swimming pool and factory where anti-corrosiveness is required.
Ceramic fiber paper is adopted for this rotor and metal silicate is synthesized
into the paper by chemical reactions. We applied a very similar method
to SSCR dehumidifier rotor which is also developed by us. As a result,
it has high efficiency for exchanging latent heat, superiority in anti-corrosiveness
and salt-resistance, and it can be washed by water. We have had many installations
in Japan as well as in overseas countries. |
