Our Products
Plate Heat Exchangers
We are a sales and distribution partner for gasketed plate heat exchangers, brazed plate heat exchangers, free-flow plate heat exchangers, condensers and evaporators, semi-welded heat exchangers, double-wall heat exchangers, and plate-and-shell heat exchangers, made from materials such as stainless steel and titanium, ensuring optimal heat transfer and a long service life.
Gasketed plate heat exchangers
Gasketed plate heat exchangers are a highly efficient solution for industrial applications where reliability, easy maintenance, and optimal heat transfer are essential. Thanks to their modular design, they can be quickly disassembled, cleaned, and adapted to the specific requirements of any project.
This type of heat exchanger delivers excellent performance across a wide range of temperatures and pressures, making it suitable for heating and cooling systems, energy installations, and process industries. The gasketed construction simplifies servicing and extends the operational lifespan of the system.
SonFlow plate heat exchangers are designed according to the highest industrial standards and allow easy adjustment of the number of plates to match the application’s needs. This ensures flexibility, high energy efficiency, and long-term cost savings.
Brazed plate heat exchangers
Brazed plate heat exchangers are a compact and efficient solution for industrial systems where reliable operation under high pressure and stable temperature conditions is essential. Thanks to their brazed construction, they provide excellent heat transfer in minimal space and require no regular service or maintenance.
This type of heat exchanger is particularly suitable for heating and cooling installations, glycol systems, air conditioning, heat pumps, and other applications where high energy efficiency and reliability are crucial. The absence of gaskets eliminates the risk of leaks, reduces operating costs, and extends the system’s service life.
SonFlow brazed plate heat exchangers stand out with their compact dimensions, optimized hydraulics, and durability under demanding operating conditions. This makes them an excellent choice for projects with limited space and high performance requirements.
Free-Flow plate heat exchangers
Free Flow plate heat exchangers are specifically designed for industrial applications involving fluids with a high content of impurities, fibers, or particles. Thanks to the open channel design between the plates, this type of heat exchanger eliminates the risk of clogging and ensures stable heat transfer even under the most demanding conditions.
The Free Flow construction is ideal for processes in the food and beverage, processing, chemical, and energy industries, as well as for applications with unfiltered or viscous fluids. With no turbulence zones and a larger hydraulic cross-section, these heat exchangers provide low pressure drop and high energy efficiency.
SonFlow models deliver reliable performance, easy maintenance, and long service life. They are designed in accordance with industrial standards for durability and safety, making them an excellent solution for environments with increased demands on reliability and efficiency.
Condenser | Evaporator
Industrial plate heat exchangers of the Condenser/Evaporator type are designed for the most demanding technological processes. SonFlow models are specifically developed for condensing low-pressure steam and for evaporation under conditions of high temperature and pressure differentials.
These systems are ideal for industries such as food and beverage, sugar production, biogas, pulp and paper, mining, chemical, petrochemical, and alcohol processing.
Their main advantages include specially engineered plates with asymmetric flow — a large steam inlet and a smaller cooling water and condensate inlet/outlet — ensuring optimal heat transfer.
If you are looking for a premium solution for heavy-duty industrial heat transfer processes, explore our range of industrial plate condensers and evaporators — designed for high loads, maximum efficiency, and continuous operation under critical conditions.
