Split systems Polair Standard

Split system Standard is an industrial refrigeration unit operating in low and medium temperature modes. The main functional node of these devices is a powerful hermetic piston type compressor, the production of which is carried out in the territory of the best European concerns for the production of compressor equipment.

Dry nitrogen (R 404) is used as a refrigerant in the refrigeration equipment of the Standard class. Due to this, the temperature in the chamber can range from -50C (SM109S) to -180C (SB331S). Condensate is removed from the system using 1 m long drainage, which in the basic configuration comes with hermetically soldered from both ends.

Split systems Polair Professionale

Split systems from Polair company of this class are high-tech climate equipment in which special couplings are used to connect the unit output to the connecting tubes. Professional split systems are supplied with upgraded air coolers as standard, so that the efficiency of the system increases by 30%.

Distinctive specifications:

  • Thanks to the use of special couplings, which contain a membrane that breaks only when the ends of the tubes are connected and the unit exits, a tight, closed-loop cold circuit is obtained.
  • When using modern membrane couplings for connecting functional units, installation is performed without errors.
  • Choosing a Professionale series will allow you to get high-tech equipment exclusively European production.

Split systems with microchannel capacitor

Split systems with aluminum capacitor
Split systems with aluminum capacitor

Unlike the previous 2 split systems, these devices in the basic configuration are equipped with a microchannel capacitor made of a special aluminum alloy. Thanks to the use of this technology, systems have the following technical characteristics:

Technical features of air conditioners with microchannel condenser:

  • the dimensions of the heat exchanger are significantly reduced;
  • the mass of the whole set is reduced;
  • standard R404 refrigerant consumption is reduced from 25 to 30%;
  • the lifetime of the microchannel capacitor is increased due to the inertness of the aluminum alloy to the air-water medium (does not corrode);
  • Due to the smaller amount of refrigerant and correspondingly less load of the compressor unit, the device’s own energy consumption is significantly reduced.

Monoblocks

Monoblock Polaris - refrigeration equipment manufactured in accordance with GOST 23833-95 for operation in medium temperature (MM) and low temperature (MV) modes. These devices are capable of operating at ambient temperatures up to +400C. In the case of installation of HVAC equipment of this design on the street ("Winter Set"), the ambient temperature should not fall below -100WITH.

A distinctive feature of Polaris monoblocks is the optional ability to connect a remote control that allows you to control the system from a distance.
