Are you having difficulties with your refrigeration units? At Kavidoors, we have identified the five most common situations that can occur in these types of units. We offer solutions to help you in case you are experiencing any of these situations. If you need further assistance, do not hesitate to contact us and we will find the best way to solve your problems.
1. Ice formation
At supermarkets and industries, the buildup of ice on refrigerator doors is a common problem. This issue can lead to accidents, such as slips on the slippery floor, as well as the growth of bacteria and mold on the ceiling of the refrigeration chamber. Additionally, the quality of stored products can be affected by the presence of ice on their surfaces. In summary, this problem can generate various inconveniences.
At Kavidoors, we have come up with a solution to the problem of ice buildup on refrigeration doors: we have created a double canvas high-speed door with a dry air recirculation system that removes the absolute moisture from the air. In this way, the air is expelled without condensation, which prevents the formation of ice on the refrigeration doors. Unlike other processes that only reduce the relative humidity of the air, our system eliminates the actual amount of water contained in the air.
2. Uneven flooring
In some situations, installing a refrigeration door can be complicated due to problems with uneven flooring. Although our doors are designed for level floors, we can adjust them to accommodate situations where the door does not fit completely snug to the floor or if there is a slope in the pavement. This ensures that the door does not allow light to pass through underneath and that it fits properly to the floor.
The process of adjusting the door will depend on the type of door being installed, whether it is a swinging door or a sliding door. For swinging doors, the adjustment will be made using the hinge located at the bottom of the door. On the other hand, for sliding doors, adjustment will be made using screws located on the top of the door. If you would like more information on these adjustment methods, you can click here.
3. Corrosion at the cold room
Cold storage doors are constantly exposed to harsh environments both indoors and outdoors, which can cause significant corrosion wear and tear. Many companies that manufacture refrigerator doors use 25µ polyester to coat the exterior of the doors. However, this material is not suitable for highly corrosive environments and over time, the door can rust or suffer damage to its coating.
At Kavidoors, we have found a solution to prevent corrosion in refrigerator doors by installing a suitable coating for each case, whether for the interior or exterior of the door. In the case of the interior, we use a 50µ PET or PVC Food Safe coating, which is resistant to scratches, chemicals, and high levels of humidity. On the other hand, for refrigerator doors that are exposed to the exterior, we use Granite HDX of 55µ, as PET is not resistant to the ultraviolet rays of the sun, which can wear and crack the material.
The performance of the materials used to cover the exterior of a refrigeration door depends on the environmental conditions to which they are exposed.

4. The incorrect selection of the door in the installation of automatic or manual doors
It is important to consider the choice between installing a manual or automatic door as it will have an impact on daily efficiency. Although the thermal insulation capacity is the same for both options since it depends on the door leaf, an automatic door allows for faster access and exit, resulting in lower temperature loss. In the case of an automatic sliding refrigeration door, the operator can order the opening from the control, enter directly, and start working, as the door closes automatically. Otherwise, they would have to get off the machinery, open the door manually, get back on, and close the door before starting to work.
The choice between an automatic or manual door will depend on the intended use and the level of daily traffic expected. If the traffic is high, it is recommended to install an automatic door to save time, energy, and costs. In some situations, manual doors can be left open due to high traffic in the warehouse or refrigeration chamber, which can cause ice buildup and other problems. However, any manual door can be automated.
5. Lack of preventive maintenance
More than 80% of breakdowns in refrigeration chambers are due to lack of preventive maintenance. Not carrying out this maintenance can lead to loss of refrigeration, increased energy consumption, and other anomalies. In addition, it may result in the exclusion of the product warranty if the problem is due to lack of preventive maintenance or failure to observe manufacturer recommendations, such as those included in the manuals. Therefore, it is essential to carry out periodic inspections and preventive maintenance tasks to ensure proper operation and extend the service life of the refrigeration chamber.
