Coppers of heating of Grandeg GD BIO of 15-25-40 kW

Grandeg BIO - the pelletny copper of heating using as fuel pellets (wood granules), and if necessary firewood.

GD-BIO 25 - power: from 5 to 25 kW.
GD-BIO 40 - power: from 10 to 40 kW.
Coppers of heating of the BIO series include such checked and reliable knots from the previous models:

· A torch from industrial coppers of the TURBO series;

· System of giving of granules with the built-in rotor lock similar to the big power used on coppers;

· System of automatic equipment on the basis of well proved frequency converter.

Advantages of coppers of GD-BIO

At the same time coppers of the BIO series have additional potential:

· The torch of TURBO allows to use cheaper fuel of bad quality, at the same time providing better combustion;

· The copper can be completed with three combined standard bunkers on 200 or 370 or 625 kg of granules;

· The bunker can be manufactured independently, any size;

· The copper can be heated not only granules (pellets) , but also firewood;

· The copper can be established in system of heating with natural circulation of water;

· Thanks to horizontal convective part, the copper can be established to the room with a low ceiling;

· All cleaning of a copper can be made from its forward part.

If you choose Grandeg BIO, you receive a successful combination of expensive industrial technologies in a compact, cheap and reliable copper that guarantees the minimum operational costs on service and long service life - till 20 years.

On convenience of operation and the received comfort new coppers of Grandeg BIO are similar to gas and liquid-fuel coppers. Automatic equipment of a copper to take care of its independent work on maintenance of the heating mode chosen by you. Now, at the corresponding size of the bunker and quality of fuel, duration of independent work of a copper can reach about one month.
The standard set of system of protection of a heating copper consisting of thermoprotection of the engine of the screw, the safety valve, thermoprotection of the copper and the general protection against short circuits will be prevented by undesirable consequences at failures in operation of the power supply network and system of heating.

The sensor of existence of granules in the bunker will allow you to learn in due time about fuel level in the bunker and on its termination will stop a copper for prevention of fast cooling of water in a copper.
Choosing Grandeg BIO, you can not only save the means upon purchase of a pelletny copper and the subsequent expenses on heating, but also receive the maximum convenience and reliability at long operation of a copper.
