Supermarkets – Dehumidification & Moisture Removal
A modern supermarket environment is complex and unique.
The sheer size, scale and multitude of products, departments, people and varying temperatures required across such a facility, can create a real challenge.
Some of the issues that the industry experiences can be related to humidity, particularly in frozen food storage, either on the shop floor or in bulk storage facilities on-site and in remote cold store facilities. These issues include:
- Breakdown of the refrigeration and freezer systems
- Condensation and Ice forming inside freezer doors and display cases
- Customer frustration developing as they are unable to see the products through steamy display cases and glass doors.
- Frost shock and resultant loss of sales and product wastage
- Staff and customer discomfort from either being too hot or too cold.
Controlling the indoor air within a supermarket is crucial if it is to be operational at all times.
Take for example the current trend for upright freezer display cabinets in the majority of Supermarkets. These present the product to the customer in a very easy to view manner, but suffer from moisture ingress due to the constant opening of doors for the goods to be removed. Every time the door is opened, cold air is lost and replaced with warmer moist air from the store itself. This air is usually un-conditioned and as it hits the produce at around -180C, the result is frost shock (seen as hoar frost) and an increased load on the refrigeration to cope with the sudden change in temperature.
Simply incorporating a desiccant dehum unit in the specific air handling system for the freezer cabinets can lower the dewpoint sufficiently to prevent (or at least dramatically reduce) the incidence of frosting on product and help in reducing the additional heat loads on refrigeration plant.
Our team of specialist engineers have the knowledge, experience and skills to tackle these type of complex humidity control requirements. A dehum desiccant dehumidification system will drastically improve a supermarket’s operations and maintain the ideal humidity across the entire building.
We operate cold store dehumidification systems for Sainsbury’s, Ocado, ASDA, Tesco, Bookers, Heron Foods, Iceland, Bidvest, JJ Foods and many other smaller independent organisations, helping to create energy efficient humidity control and lower supermarket energy consumption.
