For power plants to operate reliably, the components within it must have minimal impacts from its environment, including the air, water, fuel oil and fuel gas. In addition to controlling sulphuric acid to prevent cold-end erosion and comply with environmental laws, plants must consider hygroscopic salt damage and its deliquescent properties. While hygroscopic salts are integral to the inner workings of a plant, the corrosion that it causes will shorten a station’s life if the components don’t have an appropriate surface coating.

In addition to temperatures within cold storage units and warehouses, moisture levels are of considerable importance. When relative humidity levels are too dry, goods dehydrate and shrink. When condensation levels are too high, electronics may experience problems, goods deteriorate and products may experience mold, bacterial or insect contaminations that may pose health risks to workers and consumers. By being proactive about condensation prevention, you will protect the safety of the goods processed and worker health, as well as extend the life of equipment.

Consumers rely on food processing and storage facilities to ensure the ideal environmental conditions for produce from the moment it’s picked at the field to the time it reaches a grocery store. When it comes to cold storage, humidity and temperature levels are among the most important considerations to prolong the life of fruits and vegetables. When environmental conditions are not ideal, produce deteriorates and becomes potentially harmful to consumers.

Each type of document has its own unique needs in regards to storage and preservation. Photographic materials are particularly challenging because of the variety of techniques used to preserve images on film and the different ways that they change with time and deteriorate. While photographic prints are more resilient, the film requires special storage and handling. Cold storage for the film is a popular preventive conservation measure that extends the life of historic film and averts the need for costly restorations.

Desiccants are hygroscopic substances used as drying agents. They attract water-vapor molecules from the air using an absorptive or absorptive process. They’re often open dehumidification systems used for the cold storage of food products to ensure appropriate relative humidity levels. Desiccant wheel and liquid desiccant dehumidification systems are among the most common used for cold food storage because they’re more efficient, produce less heat and prevent the formation of frost. The best system for cold storage depends on the type of food stored, the location of the storage unit and its size.
