온도 및 습도 복합 제어 / 상업용 공기 쿨링 시스템

FreeDry®

FreeDry® combines advanced desiccant dehumidification technology utilizing waste heat from refrigeration systems to supply and maintain the low dew point an ice arena needs at a very low operating cost. FreeDry also utilizes waste heat for winter heating and can provide cooling and drying as a stand-alone system during non-ice events. Available in DX or chilled water with and without exhaust air recovery.

Instead of using natural gas to reactivate the desiccant wheel, Munters’ FreeDry unit uses waste heat to dry the Munters' desiccant wheel.

FreeDry combines advanced low temperature desiccant technology with refrigeration based technology to provide a dehumidifier that can supply and maintain a low dew point in the space at a very low operating cost. In addition, the FreeDry system provides lower leaving temperature in the summer to minimize the load on the ice sheet.

The system can be sized to handle the outdoor air requirement of the facility and can provide modulating or demand control ventilation. In non-ice event mode, the system can provide cooling and heating to maintain more traditional space conditions.
