It helps control the amount of light, humidity and temperature inside the facility, which turns to an improvement of the crop conditions and a reduction of the energy costs. The screen has a flexible and easily-folding structure that once folded takes up minimum space and allows entering the maximum amount of light. It may be automatically run by means of a solar radiation sensor.

The hot air generators are especially recommended in those cases where there is not an important requirement for continuous heating and as an occasional defence against freezing temperatures. The purpose of this system is to increase the productivity of the crops and their maturity in cold weather, using medium level technology. The distributionof hot air is carried out using fans and hoses.

This is a Centralised heat generation system using natural gas, diesel, biomass, geothermal heat. Water circulates through metal or PVC-Polyethylene pipes as a heat transporting agent, depending on the temperature of the hot water source, the temperature increase requirements and the crop. We offer a wide range of solutions in this area, from basic systems, to the most sophisticated systems with Open Buffer heat storage systems and use of CO2 coming from combustion gases.

The extractor fans allow forcing the ventilation inside greenhouses when the natural ventilation using roof and/or perimeter vents, does not allow reaching the desired rate of air renewal, which is an innate need for producing crops as well as livestock farms. They are often used in combination with evaporative cooling panels or water misting systems for the purpose of obtaining a certain level of cooling.

The air circulation fans or recirculation fans help obtain a suitable air movement contributing to maintain a homogeneous interior climate, avoiding hot air accumulation at the upper section of the greenhouse, reducing substantially the degree of water condensation and favouring the crops’ transpiration and CO2 absorption. They may be used as support for the extractor fans or as humidifier systems or for applying treatments.

Fertigation consists of applying simultaneously water and fertilizers through the irrigation system, supplying the nutrients required by the crops to the soil or substrate. Fertigation is especially useful in the case of drip irrigation. By means of automatic high technology fertigation equipments the water and the nutrients are perfectly placed in the absorption area of the roots, improving the rate of growth and quality of the crops. This system allows carrying out a more rational use of the water and fertilizers, respecting the environment and minimizing the environmental impact.
