How to make a freezer with your own hands?

Many modern production facilities, shops, cafes, warehouses use refrigeration facilities. Their use is due to the fact that standard refrigerators are simply unable to accommodate a sufficient number of products. In addition, the specific cost of space, cooled in this way, is significantly lower in comparison with conventional devices. Simply put, it's more profitable to use refrigerators. Today we will learn how to make a freezer with our own hands to save on the purchase of such expensive equipment.

The main ways of self-assembly of freezers

You can make a freezer for long-term storage of vegetables, meat, fruits, dairy products without the help of qualified specialists in three simple cases:

1. Buy ready-made refrigerator for assembly.
2. Manufacture of a heat-insulating sandwich panel camera.
3. Reconstruction of the old warehouse.

Important! Creating a camera in one of these ways, you can not do without refrigeration equipment for installation inside the camera in order to maintain the necessary temperature regime. Installation of such equipment without the help of qualified personnel is not easy, but it is possible if you use refrigerators or freezers.

cold-box refrigerators This is the fastest and easiest way to get a finished freezer. Prefabricated structures are a set of ready-made insulation panels filled with polyurethane foam with special fastenings of angular and straight joints.

This camera can be independently disassembled, then installed in a new location. Includes a swing door. Even without special qualification, you can assemble such a freezer with your own hands. Designs are divided into two types, which differ in the type of panel connection:

• Lock. Such cameras have built-in eccentric locks, which ensure a rigid and tight connection between the panels. They withstand multiple assemblies and disassembly.
• Slotted groove made of plastic profile. They are cheaper than assembling them with locks, but the joints in them must necessarily be sealed. In addition, plastic fastenings do not tighten the panels so firmly.

You need to decide on the type of camera, its size, volume, order from the supplier, then collect on site according to the instructions.

Important! The cost of such a design will be slightly higher than in the options described below, but it's easier than this way to get a camera you will not find.

Assembling the refrigerating chamber from sandwich panels

If you are interested in how to make a freezer of a budget variant, then this method will definitely suit you. But here you will have to carefully calculate how many panels you need to make the structure, what length it should be.

Important! Different manufacturers produce panels of different widths in the range from 1100 to 1200 mm. Based on this and taking into account the parameters of the future camera, first of all, calculate the length and number of panels that need to be purchased.

The assembly process, the scheme of fixing angular and straight joints, as a rule, is described in detail in the documentation from the manufacturer.

Basic assembly instructions:

• When assembling panels, avoid the formation of so-called thermal bridges at the corner joints that come in contact with the outer and inner metal plating. To prevent heat bridges, it is necessary to perform their tears, that is, to make slots inside the metal skin of the corner panels, exactly in those places where they exit.

Important! Similarly come with corner joints of wall panels with ceiling and floor panels.

• Those cameras in which the temperature is kept above zero degrees are often left without a heat-insulating floor. This greatly simplifies the arrival of the equipment used for loading, saves money for the purchase of materials for thermal insulation. But in this case it is recommended to install more powerful refrigeration equipment, which affects the increase in electricity consumption.
• The operations connected with the thermal bridge breakage must also be performed when mounting multisection cameras with different temperature modes. In this case, the metal inner covering of the floor, walls, ceiling is cut through directly into the installation site of the partition. Thus, the thermal bridge is broken directly between sections.
• Purchase for assembly requires such additional elements as the angular profile and the latch to fix the corner joints of the panels, as well as the sealant and, of course, the required size of the door.
• The door will require a special refrigerator with thermal insulation made of polyurethane foam.

Once you have purchased all the necessary parts, designs, elements, you can start assembling.

Reconstruction of the old

warehouse The last option, how to make a freezer, is to convert the existing storage room:

• If you make the thermal insulation of the walls, you will get the perfect refrigerator for storing a large number of products.
• You can perform thermal insulation using the same sandwich panels described above. Only in this version they are fixed to the ceiling and walls with the help of special fasteners.
• Metal fasteners create multiple thermal bridges, which often leads to the formation of condensation, which may even cause rust. Therefore, it is recommended to use fasteners made of heat-insulating materials, for example, polyamide studs. But they will cost more than metal parts.
• In this case, it is also necessary to coat the walls with metal to ensure a decent level of thermal insulation.

Important! This work is quite laborious, but the result is worth it. If you are not sure in your abilities, then it's better to use ready-made panels.

When choosing freezers for food, take into account the conditions under which they should be stored. If everything is calculated, collected and used correctly, then you will save considerably on financial costs.
