A friend in the food industry once asked if the air curtain could be turned off in winter, because the forklift workers couldn't stand the cold wind.

Under normal circumstances, most outdoor insects begin to overwinter when the temperature reaches 15°C, but chironomids, such as chironomids, have their peak activity in early winter, and chironomids are just the type of invasive flying insects that are often monitored indoors. The lakes and rivers are its breeding places.

In the case of uncertainty about the surrounding environment and the factors of temperature change, it is recommended to open the air curtain normally in winter. Of course, if you need to reduce the discomfort of workers in winter, you can consider a flat air curtain with an air outlet, or use an electric heating air curtain.

Why should an air curtain be installed in the cold storage?

In order to reduce the air entering the warehouse when the door of the cold storage is opened, the maintenance of the cold storage will cause the temperature of the storage to rise and a large amount of heat and humidity exchange will cause the cooling fan or evaporator exhaust pipe to freeze, which will cause the storage temperature to fluctuate and affect the quality of food. The reasonable use of travel switches to make the cold air curtain and the refrigerated door interlock, start the cold air curtain when the refrigerated door is opened, cut off the connection between the inside and outside of the warehouse, or use a plastic door curtain. Minimize the number of opening times and opening time, carry out effective maintenance on the refrigerated door to ensure that the refrigerated door can be opened and closed without any reason, and check the function of the sealing strip and electric heating wire on a regular basis.
