Cold storages are usually used in two general types above zero and below zero. A cold room with a temperature above zero, which is around 0 to 6 degrees Celsius, is mainly used to store food, fruit, dairy products, and medicine. The main use of sub-zero cold stores (about -18 degrees) is in the preparation and storage of frozen meat products such as meat, chicken and fish.

•      Cold storages are of special importance in terms of temperature and humidity required during the day and night. Therefore, by using a smart monitoring system with continuous monitoring of important parameters, it is possible to prevent the occurrence of losses due to the improper operation of cold storages.
•      The control and monitoring system of Tontab Pars Company, with timely warning of possible errors such as temperature increase, humidity decrease, cooling system interruption, electrical panel problems and other issues through the local HMI display as well as siren and sending SMS to the relevant official. Informs as soon as possible.
•      This system is able to control the space of cold storages in order to preserve food for a long time and prevent their rapid spoilage.
•      In this method, the intelligent system by regularly monitoring the oxygen concentration of the cold room environment, through the injection of carbon dioxide gas and changing the composition of the air, adjusts the oxygen concentration of the atmosphere in an optimal condition, so that with the help of this process, food spoilage is delayed and the conditions Provide for long-term storage.
