Why to dehumidify

into protect the ice. Since the surface temperature is low when the indoor humidity is high, icyfogs come to existence easily on the ice, especially in high-humidity seasons. Condensed water, which may drop on the ice within the building, may soften the surface and the ice condition turns worse. As a result, freguent maintenance of the ice surface is necessary.

into protect the architecture. Since fresh air, athletes, audience and the other possible humidity sources may bring a huge amount of wet air into the building, especially in high-humidity and high-temperature seasons, the humidity may cause the condensation in the building andon the surface of facility, and hence lead to an expedited corrosion. The condensed water onthe roof may drop to the ice surface as well.

Varieties of dehumidification in ice-skating halls

Refrigeration Dehumidifier

Mechanism:wet air is cooled below zero degree so its humidity comes out of air and turns into condensed water.Since the temperature ranges from 20-23 degree and the humi dity is below 65%,a relatively dry state,for the air passing through the venue,the power cons umption is much higher than absorption based dehumidifier.As a result,such application is less used in other countries.

Desiccant rotor was first used for ice-skating places in Europe thirty years ago.Rotor ab sorbs the water molecules in processing sector and releases them in regeneration sector with higher temperature.In such a way,the water has been removed from the wet air and becom esdry.This method has been useduntil now.

Dryer new technology

After six years of research and development by Dryer,a new product,low temperature regenerative rotor,has been launched.At present,it is the world's first hydrophobic material based rotor which can utilize the low level waste heat to regenerate,such as heat of condens ation from the coolers.

Compared with traditional desiccantrotor,low temperature regenerative rotor reduces energy consumption in regeneration process and hence the running cost after the commissio ning.Dryer low temperature regeneration dehumidification system is warmly welcome by ice -skating places in Europe.It is a system which hardly consume energy without counting the  processing fan.Dryer customers are ready to use the systems full day to guard facilities andi ce surface in the ice-skating places.

With such edge-breaking technology,Dryer winsgreat attention from ice-skating plac es across the border.

Case study:the dehumidification system installed for a 800 square meter indoor ice rink,saves 210 to 220 degree of electric power per hour.The DM2 dehumidifier is immediately accepted by the customer with its excellent cost performance.This is our promise to Dryer customers:one summer to recoup the initial investment!
