Control heat exchangers, control heat flows intelligently
Our heating system technology is the key to efficient energy use. It ensures the smooth interaction of all heat sources and consumers, such as fresh water heaters (instantaneous water heaters), heating cylinders, heat generators including solar thermal systems and heating circuits. A centralized heat management system regulates the use of heat exchangers and pumps. It regulates the heat flows precisely and in line with demand. This leads to effective heat utilization and maximizes the energy efficiency of your system.
Tailor-made solutions for your heat flows
Our products enable customized solutions for your heating system. The VarCon380 for example, allows the integration of various function modules, creates transparency of all heat flows through monitoring and offers integrated data recording. Operation and remote maintenance via browser-based end devices or optional touch displays are optional. This makes the system controller even easier to use.
If required, we also enable connections to a building management system or to the varmeco Management Server and offer system visualizations. This allows you to monitor your heating system, including all heat flows, in a clear user interface and optimize it (or have it optimized) in terms of comfort and energy use.
Efficient fresh water technology for the highest demands
Our Fresh water technology (fresh water station) sets standards in terms of efficiency and performance. The fresh water heaters only work when required - when you draw domestic hot water or the hot water circulation requires additional heating. This means that the fresh water station requires as little energy as possible. At the same time, the control system ensures maximum hot water convenience - the domestic hot water is provided virtually to the degree - and saves valuable resources.
Experts in heat flows, heat utilization and heat recovery
At varmeco, we pride ourselves not only on offering state-of-the-art products, but also on providing comprehensive expertise in the design of the necessary system technology and control engineering. This includes making the best possible use of heat, utilizing heat recovery and using fossil heat sources as little as possible. This is achieved through intelligent management of heat sources and heat flows, with a preference for renewable heat sources such as Solar thermal energy. Or through heat recovery or waste heat recovery - a promising approach in the commercial sector, where cooling and refrigeration systems, for example, often supply waste heat that can be made available for heating technology with the help of our eXergiemaschine. Or in indoor swimming pools, the energy from warm waste water can be used to support pool water heating with heat recovery. The list of possible examples seems endless...
Our experts will be happy to advise you and work with you to find the best solution for your specific project - whether for a residential building, public facilities or sports facilities, for commercial operations or industrial use. We will show you how you can make your heat flows more efficient through heat recovery.
What is important for a heat exchanger
Heat transfer is of great importance in heating systems. Therefore, the following features must be considered when choosing a (plate) heat exchanger:
- Compactness - space-saving design with high efficiency and increased operational safety requirements
- Design - optimized design for long service life and low soiling tendency
- Area - the decisive factor is the usable heat exchanger area, i.e. the active area. The installed (usually designated) area cannot be used to 100%.
- Pressure losses - a pressure loss that is too high leads to higher energy requirements and therefore higher operating costs. On the other hand, too little pressure loss leads to poor turbulence, poor heat transfer and greater susceptibility to fouling. A high pressure loss promotes the shear force on the plate and thus the self-cleaning effect of the plate heat exchanger.
- Coarseness - Heat exchangers should be designed according to realistic operating conditions. However, a very small adjustment of the coarseness can have a very large effect on the size and price of a heat exchanger. Too small a gradient makes the exchanger large and therefore expensive.
- Distribution of the medium - optimum inflow distribution is required in order to serve the channels evenly and use the area efficiently. Different velocities in the ducts mean that some areas are poorly utilized. This reduces performance and promotes fouling (and even blockages) of the heat exchanger.
- Plate depth - one criterion that is usually ignored is the plate depth. This must be selected based on the medium used.
- Service friendliness - easy to maintain heat exchangers are simple to open and close and can be quickly sealed again (short downtimes).
