SonFlow SFB60 brazed plate heat exchanger
KONTECH, official distributor of SonFlow A/S, supplies SonFlow SFB60 brazed plate heat exchangers for professional applications in Greece, Cyprus, Romania and other EU markets. SFB60 is a SonFlow SFB series of brazed plate heat exchangers, represented by the SFB61 model. The model is used for liquid-to-liquid heat transfer where compact design, suitable configuration and operation at defined temperatures and pressures are required.
Brazed plate heat exchanger for HVAC, refrigeration, heat pump and industrial systems
The SonFlow SFB60 series is part of the SonFlow SFB range of brazed plate heat exchangers and includes the SFB61 model. The SFB61 is used for liquid-to-liquid heat transfer in professional HVAC, refrigeration, heat pump, heating, cooling and industrial applications where compact dimensions, suitable configuration and operation within defined parameters are important.
The construction is copper-brazed and gasket-free. The heat exchanger is built with corrugated AISI 316 stainless steel plates in TL, TM or TK profile options, brazed with copper in a vacuum process. This creates a compact and permanently sealed plate pack with a large heat transfer surface in relation to the overall dimensions of the unit.
Heat exchangers from the SFB60 series can be used both in new installations and for replacement of existing units. They are available with design pressure options of 16 bar, 25 bar and 40 bar, several connection types and plate profile options TL, TM or TK, depending on the application.
SonFlow SFB61 matches the overall dimensions and connection layout of SL140 under corresponding operating parameters. This makes it a practical option when replacing an existing SL140 where maintaining the existing installation dimensions and connections is required. Certain SFB61 configurations are available from stock for fast shipment. Send an inquiry to confirm current availability and lead time for the required configuration.
SFB60 is part of the SonFlow range of brazed plate heat exchangers.
