Today, many companies are engaged in the manufacture and sale of a variety of equipment. Monoblocks Polair are refrigeration units that are already equipped and ready for use on modular refrigerators. The plant of this company for the production of monoblocks is located in the city of Volzhsk.
Why Polair?
As for the production of Polair monoblocks, they, like other equipment from this manufacturer, are produced at the Sovitalprodmash plant. The complex is considered the largest in Europe high-tech and automated production building. All equipment goes through a complete assembly cycle right here, and there is also a conveyor assembly.
Certain features of the production technology make it possible to produce Polair monoblocks with reliability and quality that surpasses analogues of all competitors. In addition, the company has its own research center, as well as a large testing laboratory, which has all the necessary certificates for testing. Therefore, Polair monoblocks are considered the highest quality.
Different types of units
Today, the company is engaged in the production and production of monoblocks of two types.
One of the main types of candy bar Polair - MM. This is a medium temperature unit, which is designed to maintain the temperature in the range from -6 to +6 degrees Celsius.
The second type of monoblock MV is low temperature. He is able to maintain the temperature inside the refrigerator up to -18 degrees Celsius, provided that the ambient temperature is in the range from 12 to 40 degrees.
The candy bar itself is a completely sealed system that operates on R-22 refrigerant or its equivalent. The temperature setting of the Polair monoblock is carried out automatically in accordance with the cooled volume. In addition to it, the device also includes a control unit, a device for automatic defrosting.
In addition, there is also an automatic removal of melt water due to the presence of a forced evaporation system. As for the production of the hull, it is usually made of sheet painted Finnish hot-dip galvanized steel.
Constructive description
Structurally, the monoblock consists of such parts as a compressor with start-up valves, a coil for evaporating melt water, a condenser, a filter for drainage, an evaporator, a liquid separator, as well as a pressure switch and a control panel for the device.
For control is attached instructions for a candy bar Polair. On the control panel of the device is an element of control and, in fact, control. A is a backlit general switch, and B is the control unit itself.
In order for the monoblock to be able to automatically maintain the temperature in the refrigerator, as well as for the possibility of adjusting this parameter, the Polair monoblock circuit has an electronic temperature controller, or just a controller. For optimal operation of this device, it has its own sensor, which is located inside the refrigerator.
Device operation
As for the operation of the unit, it starts with connecting the chiller, it is a monoblock, to the network. Connection should be through an automatic switch. In order to start the all-in-one, you must turn on the switch, which is usually indicated on the diagrams as QG.
Immediately after this, power will be supplied to the automatic temperature controller. He will begin to control the cooling process in the chamber, and will also lead the defrosting process.
If the monoblock will work at low temperatures, then it should be in the design of a rheostat type TR1. The peculiarity of the rheostat is that it will automatically turn off the refrigerator if the ambient temperature reaches -10 degrees Celsius or lower. In this case, you should know that the network connection diode will still be on, but the controller’s indication will disappear. If the ambient temperature rises to 5 degrees Celsius, then elements such as a system for controlling the speed of rotation of the blower of the condenser are included in the work. In addition to this system, the crankcase heating of the controller and compressor is also included.
