The perfect climate for high-quality goods: Dehumidification in supermarkets

Trotec industrial dryers reliably fight the formation of condensate, icing up as well as high energy costs, thus ensuring the perfect climate control and goods of the highest quality!

A supermarket has various sections requiring different climate conditions. For instance there are fresh food areas holding fruit and vegetables which need to be cooled constantly to keep the goods fresh for as long as possible. It gets even colder at fresh meat counters and in the frozen food section. A run-of-the-mill air-conditioning system can usually not efficiently cater to such a wide variety of air conditioning needs. For what follows from the rooms’ humidity and the different temperatures is condensation, corrosion, even an affected hygiene. The solution is provided in form of powerful dehumidifiers. The stationary industrial dryers of the TTR series from Trotec promise an effective and reliable humidity regulation in the entire supermarket – for prime quality of the goods and high customer satisfaction. Another bonus comes in form of remarkable energy savings.

Going grocery shopping in the supermarket should be an agreeable and stimulating experience for the customer. Most people like to stroll through the aisles unhurriedly. They want to find nothing but sorted goods in undamaged packaging, choose from fresh produce and examine frozen foods in excellent condition. The supermarket owner is accordingly anxious to offer nothing but products of prime quality and in top condition. This is, however, not as easy as it sounds given that the different sections in which the goods are stored and put on display require the most diverse climate conditions. A standard air-conditioning system cannot just meet these demanding requirements without further ado. One major problem is literally in the air: we are, of course, talking of the air moisture. If the humidity level is not optimally regulated, the consequences can be profound. Condensate settles on the products’ surface. The moisture can cause the goods to freeze over, at worst rendering them inedible. Customers quickly feel uneasy in excessively cooled areas. And the evaporators are stressed unnecessarily.

Taking the load off air-conditioning systems and saving energy

An excessively high humidity level in the supermarket leads to a reduced quality of the goods and compromises the customers’ well-being. Moreover, the operation of an air-conditioning system produces high energy costs. Too high humidity also affects the packaging with mould growth and mildew stains as possible consequences. The risk of an increased formation of germs must not be underestimated either. If condensate accumulates on unpacked fresh produce such as cold cuts, meat and cheese, germs can form and spread quickly. The odour nuisance also increases.

The perfect climate thanks to focussed humidity regulation

An effective dehumidification concept is absolutely indispensable for the successful operation of a contemporary supermarket. Optimized climate conditions for all sections of the supermarket can only be achieved by a high-performance drying technology. This is where Trotec’s stationary industrial dryers of the TTR series come into play. For they are true allrounders – especially at low ambient temperatures. The load on the air-conditioning system is reduced which saves energy costs in the same breath. Furthermore, smooth surfaces dry off faster after cleaning, thus minimizing slip hazards.

The advantages of using dehumidifiers in supermarkets at a glance:

  • no condensation
  • quality assurance of products
  • prevention of germ formation
  • significant reduction of energy costs
  • less noticeable perceived coldness for customers
  • significantly lower odour nuisance
  • quick drying after cleaning work
  • no slip hazard

The stationary TTR industrial dryers from Trotec

All dehumidifiers of the TTR series come with a closed dehumidification system. This means that no additional fresh air supply is needed. The models can be subsequently installed without difficulty and adapted to the environmental requirements. The devices particularly impress with their broad operating range from -15 to +70 degrees Celsius and their capacity to dehumidify any working area quickly and efficiently.

Durable, low in maintenance and flexibly adjustable – that is what the models of the TTR dehumidification series stand for. They are available in different versions: ranging from the TTR 800, the compact, high-performance industrial desiccant dehumidifier with a dehumidification performance of 86.4 kg/24 h and an air flow rate of 950 m³/h, to the TTR 13500 with a maximum dehumidification performance of 74.6 kg/h.

Further application examples for air dehumidification

  • Dehumidification when filling & packing

    The humidity level during filling and packing in the chemical and pharmaceutical production must be precisely controlled. After all, the damage would be immense should hygroscopic products go lumpy, start to stick or their shelf life decrease. Using our adsorption dryers, process air conditioning is no problem.

  • Lyophilisation tunnels and frozen storage

    The food industry is facing a paradox: On the one hand, turning water into ice is the raison d'être of lyophilisation tunnels and cold stores. On the other hand, icing is a major problem in this process. Ice, hoarfrost and fog in the cooled production infrastructure lead to costly accidents and malfunctions right up to production losses. Setting up additional industrial dryers prevents icing by...
