HEATING SYSTEMS
Greenhouse cultivation requires special attention to heating and air conditioning. Choosing the right heating system is critical, both in terms of providing the necessary temperature to maintain optimal plant growth and controlling humidity. This choice should be made in a way that minimizes energy consumption and therefore costs. Ideally, the chosen heating system should be able to meet the different needs within the greenhouse. Providing a homogeneous temperature distribution in the greenhouse is very important for quality and healthy plant growth. Therefore, working with an experienced and well-equipped company when choosing a heating system maximizes your energy efficiency. Different options such as sustainable energy use or solid, liquid, gas-fired energy sources can be considered as energy sources. In today’s greenhouse applications, heating systems integrated with automation systems are preferred. These systems ensure that the greenhouse remains at the desired temperature level by regulating heating according to different sections within the greenhouse.
Since our inception, we have been continuously improving ourselves to provide our customers with high quality and efficient heating solutions. Our aim is to be the pioneer of technological developments in the sector by developing innovative and sustainable heating systems for industrial needs, just like in the greenhouse sector.
Considerations for Heating Systems:
- Heating systems must be compatible with automation systems.
- The layout of the heating center should be chosen with energy efficiency and cost savings in mind.
- It should be in a location that is easy to access for maintenance and repair.
- Water treatment systems should be used to ensure the water quality is suitable for the lifetime of the equipment.
- Brands and products with after-sales service and maintenance facilities should be preferred.
- Heating equipment must be fully integrated into the automation system.
- In regions with harsh climatic conditions, heating solutions must be designed to maintain greenhouse integrity.
- Fasteners and carriers used in the system must be robust and properly designed.
Customized Heating Systems for Greenhouse:
- Rail Heating: Provides both plant heating and facilitates the movement of rail vehicles.
- Plant Heating: It is applied to areas close to the plant root level in order to increase the yield of the plant.
- Wall Heating: Placed on greenhouse side facades and between tunnels to reduce heat transfer and ensure even heat distribution.
- Snow Melting System: Used in areas with snow and frost risk. It melts the snow accumulated on the greenhouse roof and prevents freezing in the gutters.
- Ceiling Heating System: Placed at the gutter level to increase plant yield.
- Heating Seedling Trestles: It is the heating system placed under the seedling stands.
- Subsoil Heating: It is applied under the soil in greenhouses with soil in order to increase plant yield.
Basic Components of Heating Systems:
Boilers, burners, economizers, pumps, greenhouse fittings, valves and the heating control system form the basis of these systems.
Boilers Boilers can be used for coal, biomass, pellets, natural gas, diesel, pomace, etc. can burn most fuels in solid-liquid-gas phase.
Burners Burners that burn and heat the water in the boiler using natural gas/LNG or diesel fuel are as important as the boilers. Here, the burner is particularly important for the greenhouse plant, especially if it is of high quality and works smoothly.
Pumps The main pumps used in the greenhouse heating system are frequency converter pumps that prevent the boiler-burner from operating unless necessary and automatically adjust the flow rate and temperature. In contrast, flow rate and temperature are constant in sector pumps. With the 3-way valves we use, temperature and flow rate are provided homogeneously in all sectors.
Economizers: Used to cool flue gases in natural gas-fired plants. All flue gases from the boiler are routed through the economizer where they are cooled. The heat from this process heats the water in this closed system. In most installations, hot water boilers with economizers are usually located behind or above the boiler. The energy in these installations is used to heat water. The maximum temperature of the flue gases in the economizer is 210 °C. The water circulating in the installation is heated to a maximum temperature of 95 °C using the extra efficiency of the flue gas economizer. The economizer is part of a closed system with a maximum allowable pressure of 3 bar.
Greenhouse Fittings & Valves: Valves used in heating installations are used to obtain variable flow or constant flow water regimes and to reach the desired water temperature with an economical performance. We prefer high quality standards for valves such as butterfly valves, shut-off valves, strainers and check valves used for installation.
Heating Collectors: In order for the heating system to work flawlessly, it is necessary to design and implement the correct collector design. For the most suitable collector options, attention should be paid to the projects issued by experts. The systems to be used on the collector must have the price/performance/quality trio.
Improperly designed collector systems create an inhomogeneous heating environment in the greenhouse, reducing crop yields or causing plant death and disease.
