Technical Information


Removing or reducing the sources of heat from the environment is called refrigiration. Removing or reducing the sources of heat is usually provided in our day by means of compressing the refrigirant and sending it to the environment where heat will be removed, so that it will take the necessary heat from the environment to evoperate.


Cold Storage:

Cold storages are enclosed spaces insulated against heat and humidity gain from the outside, able to control humidity level and established for the purpose of extending storage life of goods and decrease ambient temperature in food production. Sandwich panel application in cold storages around the world pursuant to production and application conditions provides significant contribution to energy saving.
Apart from these fixed mechanisms called sandwich panels, there are doors, which are moving mechanisms, in cold storages. The specifications of the doors used in cold storages should be determined with regard to staff and product contact. In case doors are operated in minus degrees °C, heater (heating coil) should be applied in accordance with unit availability. Front and back metal sheets which comprise the door wing should be independent from each other and have preventive thermal bridge to carry thermal conductivity outside the cold storage and have aluminium body holders against corrosion and bacterial growth.
There are different refrigiration systems which have same insulation values in the cold storages. These systems are in two main groups, generally using freon or ammonia as refrigirants.
The machines providing refrigiration in cold storages are called evaporator inside the cold room and condenser outside the cold room.


Thermal Shock Chambers (-30 °C / -45 °C):
Despite being a type of storage, this system, actually called quick freezing, should be defined apart from storage due to the mistakes present in the sector. Quick freezing is the process of decreasing core temperatures of fresh products to minus degrees °C determined and deemed appropriate. The chamber operates between -30 °C to -45 °C according to the type of product stored.


Deep Freezer Cold Room (-18 °C / -25 °C):
This is the type of room where products which have core temperatures of minus °C are stored for longer periods. The deep freezer cold room operates between -18 °C to -25 °C according to the type of product.


Controlled Atmosphere Room:
Controlled atmosphere rooms is an agricultural storage method in which the air, as well as the temperature and humidity of the storage room is regulated to provide that vegetables and fruits remain fresh and have minimum loss when they are stored for a longer period of time. Vegetables and fruits, as we all know, continue to ripen and age after they are picked up. This trpe of cold room ingibits ripening and ageing of the vegetables and fruits. Complete impearmeability is provided in controlled atmosphere storages. The doors are special production and joint of cold room panels are insulated in such a way providing complete impearmeability with the help of special chemicals. Viewing windows can be placed on the door, wall or the ceiling pursuant to the customer’s requirement. The condition of the products can be viewed by means of these windows. After degree of temperature is provided according to the type of products in the controlled atmosphere room, oxygen level is decreased to a level where it is almost non-existant. This process ensures that the products remain fresher and have longer storage lives without emitting any hazardous chemicals to the products or the environment.
