SonFlow SF200 Gasketed Plate Heat Exchangers
Models SF201, SF202, SF203 and SF204 with DN200 flanged connections
SonFlow SF200 is a series of gasketed plate heat exchangers with DN200 flanged connections for industrial and HVAC systems with high flow rates. KONTECH supplies models SF201, SF202, SF203 and SF204. Four plate heights provide different heat transfer areas per plate. The model and number of plates are selected according to the thermal duty, flow rates and allowable pressure drop.
The units can be opened for inspection, cleaning and replacement of plates and gaskets. Selection also accounts for the space required for installation and maintenance. The series is supplied to order. Price and delivery lead time are specified in the quotation.

Models SF201, SF202, SF203 and SF204
All four models use plates with a width of 655 mm and a horizontal port centre distance of 395 mm. Plate height determines the heat transfer area per plate. The model and number of plates are selected according to the thermal duty and hydraulic conditions.
SF201 · plate size 655 × 1054 mm
SF201 has the shortest plate height of the four models. The vertical port centre distance is 791 mm. The overall frame height in the dimensional drawing is 1403 mm.
SF202 · plate size 655 × 1354 mm
SF202 uses a plate with a height of 1354 mm. The vertical port centre distance is 1091 mm. The overall frame height shown in the dimensional drawing is 1708 mm.
SF203 · plate size 655 × 1752 mm
SF203 uses a plate with a height of 1752 mm. The vertical port centre distance is 1489 mm. The overall frame height shown in the dimensional drawing is 2106 mm.
SF204 · plate size 655 × 2154 mm
SF204 has the tallest plate of the four models supplied by KONTECH. The vertical port centre distance is 1891 mm. The overall frame height is 2506 mm.
When to consider SF200
KONTECH recommends considering the SF200 series for heat transfer between fluids at high flow rates where DN200 flanged connections are required. The gasketed plate heat exchanger can be opened for mechanical cleaning and replacement of individual plates and gaskets.
Four plate heights provide options during sizing. A taller plate offers more heat transfer area, but model selection also depends on temperatures, flow rates and allowable pressure drop. Installation planning accounts for the overall dimensions and weight of the selected configuration. Space is required to open the unit, remove plates and carry out maintenance.
When to consider another series
Where connection sizes, flow rates or installation space differ, consider the other gasketed plate heat exchanger series.
For fluids containing particles or fibres, or fluids with higher viscosity, consider Free Flow plate heat exchangers.
For applications with clean fluids where access to the plates for mechanical cleaning is not required, a brazed plate heat exchanger may be considered. Suitability is checked against the thermal duty, flow rates and allowable pressure drop.
Typical applications of SonFlow SF200
- Central HVAC systems: Heat transfer between water or water-glycol circuits in central heating and cooling systems. Selection accounts for the thermal duty, flow rates and allowable pressure drop.
- Industrial processes: Heating and cooling of process fluids, equipment cooling and waste heat recovery. Materials are selected according to fluid composition and operating temperatures.
- Data centres: Heat transfer between cooling circuits with high flow rates. The configuration is selected according to the required thermal duty, temperature approach and hydraulic constraints of the system.
- Marine applications: Heat transfer in cooling and auxiliary systems.
Configuration according to fluids and operating conditions
Plates
The SF200 series is available with plates in AISI 304, AISI 316 or titanium. Material selection accounts for the chemical composition of the fluids, temperatures and corrosion resistance requirements. The number of plates is determined during sizing.
Frame
A carbon steel frame painted in RAL 5010 is available with a design pressure of 10 bar, 16 bar or 25 bar. Frame size depends on the model and plate pack. Selection accounts for installation and maintenance requirements.
Gaskets
The SF200 series is available with NBR or EPDM Hang-on gaskets with glue-free attachment. The material is selected according to the fluids, temperatures and cleaning agents. The gasket type and material are specified in the quotation.
Connections
The SF200 series is supplied with DN200 flanged connections. Rubber-lined connections or painted connections are selected according to the fluid. The flange standard and pressure rating are specified in the quotation. Mating pipe flanges are not included in the supply.

Other SF models
Frequently asked questions
The four models use plates with the same width and different heights. This changes the heat transfer area per plate and the overall unit dimensions. The model and number of plates are selected according to temperatures, flow rates and allowable pressure drop.
In addition to the unit’s overall dimensions, space is required to open the frame and remove the plates. Configuration weight and installation access are also considered. Final dimensions are specified in the drawing for the selected configuration.
Suitability is checked against the operating data, overall dimensions and connections of the existing unit. Send a photo of the nameplate and an available drawing or dimensions. KONTECH assesses the replacement configuration according to the thermal duty and installation requirements.
A configuration with titanium plates and suitable connection lining is considered for seawater. Gaskets are selected according to temperatures and cleaning methods. Send the water composition and operating data so we can check the configuration.
This depends on the available frame capacity and a new sizing calculation. Changes in temperatures, flow rates and allowable pressure drop are checked. Additional plates are proposed after assessing the existing unit and the new operating conditions.
The price of an SF200 heat exchanger depends on the model, number and material of plates, gaskets, frame and connections. Once the operating data has been clarified, KONTECH prepares a quotation with a proposed configuration and price.
