for ecological production

for subsidy programs

We design and implement greenhouse projects, because we are convinced that they provide a uniquely cost-effective possibility for the utilization of moderately warm waters. Our clients can achieve, with our heating method, up to 50% increase in energy efficiency. However, the innovation gives other benefits, too:

Waste heat or secondary geothermal fluids can be utilized

The utilization of lower temperature waters for heating is achieved by the use of extended surface heat exchangers. The key element of the technology is a plastic blanket, which covers the production media. The thermal blanket is designed to be applicable for both higher and lower temperature heating fluids, with unparalleled efficiency of use.

Helps ecological production

At blanket heating the temperature of the vegetal mass is typically higher than the temperature of the greenhouse atmosphere, so there is no vapor condensation on the plants. The low humidity atmosphere prevents the build-up of plant pathogens and the moderate temperature in the greenhouse slows down the migration and reproduction of insects. These features of the blanket heating offer good possibilities for organic farming.

Low implementation costs result in short pay-back times

Novel technologies are evaluated by the competitiveness of their products. Low implementation costs are of high importance for the users. Our heating system applies reasonably priced, but durable plastics, so your investment can pay back quickly.

Usually, with 50% less energy

The profitability of greenhouse gardening depends primarily on the price of heating energy. While the energy is getting more expensive, it is possible to find cheap sources…

Much waste heat is generated by thermal power plants, or other industrial facilities, in the form of cooling water, flue gas heat or flash steam. Energy can be obtained from low capacity (30-40°C) geothermal wells, or spent (already cooled) geothermal water flows, too.

Our projects are designed according to the characteristics of the available heat source. We apply innovative solutions to maximize the efficiency of heating. We understand that in certain cases the utilization of industrial waste heat is a must, e.g. when the overall efficiency of cogeneration units has to be increased in order to enjoy premium electricity prices. Waste heat utilization is also of high importance for geothermal systems, which may only emit spent water to the recipients at low temperatures, according to environmental regulation.

Another cheap source of heat is the cogenerated heat from biogas fueled gas engines. As the biogas plants are located far from populated areas, the agricultural utilization of their waste heat is usually the only possibility. A heat export deal can complement the income of such small cogeneration plants.

We increase the efficiency of heating

We rely on heat from biopower plants

Specifically good cooperation can be established between biopower plants and greenhouses with blanket heating. Low temperature heat transfer medium can be used, the production of which does not decrease the electric efficiency of the power plant.

A 20 MW electric capacity biopower plant is able to provide heating for a 30-40 hectare greenhouse.

We rely on heat from biopower plants

Biopower plants produce electricity or electricity and heat on the basis of biomass. If the available biomass is dry, it is usually burned. The biomass generates steam in boilers, then the steam is led to turbines, and the turbines drive electric generators.

Biomass fuels are produced from forestry or agricultural byproducts by mechanical treatment, such as chipping. Thin branches, bark, straw, corn stalks, and several other materials can be used, which have proper energy content and do not contain harmful components. The electric efficiency of biopower plants does not exceed 30%, either. Two thirds of the input energy appear as waste heat, which is not good for traditional heating purposes because of its low temperature.

We custom design technologies for spent geothermal waters

When used for heating, the geothermal water loses temperature, but still has significant energy content. The exhausted water cannot be used further in traditional heating systems, as the intensity of heat transfer falls. In order to achieve good heat transfer, we apply extended heat transfer surface with heating blankets. The cooler effluent water can be reinjected with lower energy cost.

The blankets laid on the soil do not cast shade on the plantation and disturb cultivation less. The blanket heating performs simultaneously the heating of the soil and the vegetal mass. Its surface is big enough to satisfy the heating demand of the plants by the energy content of the lukewarm water.

This innovation creates the possibility of secondary or tertiary use of geothermal fluids, while the environmental requirement of heat pollution limitation is also met.

The decline of the once successful Hungarian greenhouse sector was caused mainly by the increase of energy prices. The comeback of domestic greenhouse production can only be based on renewable energies, biomass fuels and efficient heating systems.

With the decline of domestic production, imported vegetables, produced in warmer climates, have appeared in the chain stores. Their low sales prices suggest the absence of heating costs. The consumers’ trust in such vegetables is undermined by their low nutritional value, poor taste, and the risk of high pesticide residue levels, coming from uncontrolled technology. A significant part of the consumers is ready to pay more for the domestically produced vegetables, because they are more reliable and of better quality.

The use of waste heat or biomass energy gives chance for cheaper heating, what increases the revenues of the producers. The favorable sales prices of certified organic vegetables add to that.

R. Gábor Csollák

.. as a practicing gardener of ornamental plants, I used blanket heating at Cserkeszőlő in carnation culture, with full satisfaction. It heats like the sun, the elevated temperature soil transfers the heat to the plants. I could sense that less energy was needed for the operation of the greenhouse.

…the experiments for the utilization of low temperature geothermal water in Kiskunmajsa were really convincing. The evaluation of the technology proved that the large surface heating blanket can heat the soil and the plants simultaneously.
