Prevent frosting and fogging at Cold Stores with Bry-Air Dehumidifiers

There has been immense focus on Cold Storage in recent times and specifically after the COVID-19 pandemic. The tough times has only brought to attention the importance of Cold Stores and the urgent need for quality infrastructure to help with smooth supply chain across the country and globe. It has fast become the most sought-after demand driver to support the ever growing food and pharmaceutical sectors.

India wastes tons of food from farms to processing units, and delivery which can be avoided with a better laid cold storage infrastructure. There is a lot of focus from the Government to boost the cold storage infrastructure, and help the agriculture, food processing and pharma industries to solve the problem and pave the way for future growth. Thus, cold chain is the backbone for sustaining growth, limiting food wastage and becoming self-reliant.

Cold Stores are primarily of two types – Active Cold stores and Passive Cold stores. Active ones are used for products on daily routines (ice-cream, frozen foods, etc.), have dynamic storage applications, and various temperature zones are created within the same warehouse for storing different products requiring different temperatures. Whereas Passive cold storage is built for storage of perishable goods for a long-term period, for example, storage of seeds, potato, onion, etc.

Moisture plays havoc in both Active and Passive Cold Stores. It can cause a series of reactions that lead to spoilage despite installing the best cold storage. Moisture causes frosted products, slippery floors, ice-build up on conveyor belts, and cooling coils. It leads to frost build-up near the loading docks and fog inside it.

Moisture absorption by cardboard cartons causes softening and sagging that makes them unstable and hazardous. Moreover, humidity puts a burden on defrosting costs, reduced storage space, frequent shutdowns, growth of mold and mildew, and decrease in the cooling efficiency due to water vapor loads and clogging of evaporator coils. The load is highest at the dock. 90 percent of the total load comes from two sources – Opening of doors and Ingress of fresh air.

To control the moisture menace at your cold storage facilities, Bry-Air Dehumidifiers is the ideal solution. An economic and energy-efficient solution that prevents fogging and frosting of cooling coils and saves you the hassle of rejections and reputation loss, watch a brief video on Moisture Control Solutions for Cold Stores.
