DHW plate heat exchanger SB-301 standing with two coils 10.5.02.003.02

Universal domestic hot water heat exchanger with two coils

The SB-301 DHW heat exchanger is a device designed for efficient preparation of domestic hot water in central heating installations and solar systems. Its construction with two coils allows connection of two independent heat sources, which increases the flexibility and efficiency of the system. This solution is proven both in single-family homes and in multi-family buildings or commercial facilities.

Construction and application

SB-301 is a standing heat exchanger with a capacity of 298 liters, made of high-quality steel. Two coils with areas of 1.43 m² (lower) and 0.83 m² (upper) ensure efficient heat exchange. The device is adapted to cooperate with central heating boilers, solar installations, and – optionally – with an electric heater. Anti-corrosion protection in the form of an enameled coating guarantees long-term protection against corrosion and ensures hygienic use.

Advantages for the installer and end user

• Versatility: The possibility of connecting two heat sources – a central heating boiler and a solar installation – gives great freedom in choosing the optimal water heating system.
• High efficiency: Two coils ensure fast and efficient water heating, even with high demand.
• Durability: Made of high-quality materials and with anti-corrosion protection, it guarantees a long service life. Each heat exchanger undergoes rigorous leak tests and quality control of enamel coatings.
• Thermal insulation: Thick insulation (67 mm PUR foam) minimizes heat loss, which translates into lower operating costs.
• Easy installation: Water connections with an external thread facilitate integration with the existing hydraulic installation.
• Safety: Equipped with a magnesium anode AMW.M8.500, which protects the tank against galvanic corrosion.

The heat exchanger capacity is 298 liters, the area of the lower coil is 1.43 m², and the upper one is 0.83 m². The rated pressure of the tank and coil is 1.0 MPa. The power of the lower coil is 42 kW, and the upper one is 24 kW, the insulation is 67 mm thick and made of PUR foam.

The Kospel SB-301 heat exchanger is a solid and reliable solution for anyone looking for an effective way to prepare domestic hot water in their home or company. Thanks to its versatility and high quality of workmanship, it is an investment for years to come.
