Two Units Installed in Three Months. Return on Investment in First Year. Taylor Preston Ltd is a privately owned meat slaughterer, processing and export company situated in Ngauranga Gorge near Wellington, New Zealand. In 2012 they decided to take a stand against ice build-up and condensation in their cold stores and invest in a desiccant dehumidifier.
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.
