SonFlow SFF50 Free Flow plate heat exchanger for industrial applications
KONTECH supplies SonFlow SFF50 Free Flow plate heat exchangers to engineering companies, industrial contractors and OEM customers in Greece, Romania and Cyprus for duties involving viscous, fibrous and particle-containing fluids. The model is suitable for applications where serviceability, CIP cleaning and stable flow distribution are important.
Compact Free Flow plate heat exchanger for challenging media in Greece, Romania and Cyprus
The SonFlow SFF50 series is a gasketed Free Flow plate heat exchanger range designed for fluids that may clog standard plate heat exchangers more quickly.
SFF51 is the most compact model in the series and is suitable for installations where space is limited. It is used where the fluid contains fibres, solid particles or has increased viscosity, and where access for cleaning and service is required.
The inlet area is designed for uniform flow distribution across the plate. This supports more stable operation and helps reduce uneven deposits in applications where clogging risk is higher than in standard plate heat exchanger duties.
Why Free Flow plate heat exchangers are used in Greece, Romania and Cyprus
Free Flow plate heat exchangers are selected for applications where standard plate heat exchangers may foul faster or become difficult to maintain. In this context, SonFlow SFF50 offers a practical combination of access for cleaning, controlled flow distribution and suitability for more demanding media.
- Suitable for CIP cleaning
- Easy access for service and inspection
- Designed to reduce clogging risk
- Uniform flow distribution across the plate
- No dead zones on the plate surface
- Suitable for fluids with fibres, solids and increased viscosity
Typical applications of the SFF50
SonFlow SFF50 (SFF51) is used in industrial duties involving fluids with fibres, solids and increased viscosity. Typical industries include:
- Dairy, food and beverage industry
- Sugar industry
- Biogas industry
- Wastewater industry
- Pulp and paper industry
- Mining industry
SFF51 uses plates with a specialised geometry for Free Flow duties. The wide channels allow challenging media to flow more freely, while the wave pattern is designed without contact points in the flow direction. This supports gentle product handling and helps reduce mechanical blockage and deposit build-up.
