Bom Group



Piotr Janas, located in Stawiszyn, is one of the growers in Poland who realized the advantages to buy his 13.300 m2 greenhouse, screensystem and the heatingsystem from one company. The design of the the three systems is in one hand, so Mr Janas is sure that the design of the greenhouse, the screens and the heatingsystem are adapted to each other ánd the logistics are tuned smoothly. Besides one party is responsible for the integration of the three systems.
The design of the greenhouse is based on a 8 mtr truss with 4,5 mtr sections.The postheight is 5,80 mtr with a snowload of 35 kg/m2. Much attention has been paid to reduce the costs of energy: highly isolated roofbars, small aluminium gutter and a double roofscreen and a clever designed heating system. The greenhouse is heated by the tube rail system, a double growpipe and a snowpipe near the gutter melts the snow from the tempered roofglass. The system can reach a lift in temperature of 34° C. The cooling of the greenhouse is done by the two pane vents and the extra headvents near the frontwalls.
The tomatoes grow on rockwool slabs placed on hanging gutters.
