Desiccant dehumidifiers contain no refrigerant gas, CFC's or HCFC's and so has a lower environemental impact.
Dehumidification can be achieved through two processes. Desiccant and Mechanical (refrigerant). Find out why desiccant dehumidification is better for the environment.
Apata Group Limited appears to have a problem with fruit labelling all wrapped up, thanks to some innovative thinking, and materials and technology more commonly found in the building industry. The company has warmed and dried the environment in which SunGold kiwifruit is graded inside its Kaimai packhouse, by sealing off the area with plastic used to wrap leaky buildings, and installing a dehumidifier and a heating unit.
A green New Zealand invariably means a wet New Zealand. Humidity and inappropriate amounts of water vapour constitutes a real threat to the continued preservation as once moisture damage, bacterial growth, corrosion has occurred the object to be preserved will probably never return to its former condition. . Temperature and pollutants are important factors in preserving documents. In general the humidity and temperature have to be as stable as possible and pollutants should be kept to a minimum.
A common problem with cold stores and freezers in the build up of ice on evaporator coils, surfaces and product boxes. This occurs from moisture entering the cold store every time the doors are opened. We provide solutions to stop this moisture getting in, and so reducing ice build up and decreasing defrost cycles.

When renting one of our dehumidifiers or purchasing new equipment, our gear will not only reduce new ice forming but also, when doors are closed, work on removing existing built up ice.
Our solutions are based on using desiccant rotor technology which has the ability to absorb moisture from the air irrespective of the temperature. This means we can remove moisture in very cold conditions. Dehumidification works to sublimate ice into water vapour.
When the air surrounding ice is dry, sublimation occurs. Sublimation is when ice turns directly into water vapor without first transitioning into a liquid. In cold store's and freezers sublimation occurs when the ice is surrounded by very dry air. The example typically used in most manuals/ guides is the concept of hanging a wet sweater on a line in freezing temperatures. Although it may take a few days, the wet clothing article will first freeze and then eventually dry out.
Ice build up is caused when moist air enters the cold store. Sometimes there can be thin layers of ice which has the appearance of snow. When the moist air comes in to contact with cold surfaces such as floors, walls and evaporator coils, the water vapour in the air condenses to form water and then freezes to form ice.
Moisture typically enters the cold store or freezer during door opening times.
