100000m² - Vine tomato

Gebr. Zwinkels, The Netherlands

New construction of two greenhouse blocks (100.000 m2) with a technical room. In addition, we were responsible for the heating system, the electrotechnical control system and lighting.
 
We have realized:

• Two separate greenhouses of 50.000 m2 each;
• A Venlo type greenhouse with a trellis width of 8 m (2 x 4 m), a bay size of 5 m and a post height of 5,80 m;
• A centrally located technical room.
• The complete boiler house plant with a boiler capacity of 11.650 kW;
• A CO2 dosing system;
• A pipe rail heating system and a grow pipe heating system;
• The connection of two CHP systems, each with a capacity of 2.100 kWe;
• A vertical heat storage tank with a capacity of 2,000 m3;
• 6.020 luminaires with remote control (the reflector and bulb are suspended on top and the switch gear is suspended under the cultivation gutter);
• An illuminance of 123 μ mol/m2/sec, switchable in 2 light levels, fed by means of two CHP systems in combination with 4 transformers which are placed around the CHP;
• The electrotechnical equipment is controlled by the CAN BUS system, which combines the required illuminance with the available power and thus controls both the lamps and the CHP.
