D-SMT 250 DN 25 (1 inch) group with insulation, without pump 649051

Constant temperature heating circulating unit

This circulating unit with a DN 25 (1 inch) diameter and a 250 mm spacing is designed for heating systems where precise temperature control is key. It is a comprehensive solution, ideal for both installers and end-users looking for an efficient and reliable system. The unit's design allows for easy connection to Womix flanged manifolds, simplifying installation and ensuring compatibility with other system components.

Features and application

The D-SMT 250 DN 25 unit is equipped with a rotary mixer, which allows maintaining a constant temperature in the heating circuit. The absence of a pump in the set provides flexibility in choosing the appropriate pump model, tailored to the specific needs of the installation. This allows optimizing energy efficiency and adapting the unit to existing infrastructure. The 250 mm spacing facilitates mounting in standard manifold cabinets.

The unit is primarily used in:

• Underfloor heating – precise temperature regulation ensures comfort and energy efficiency.
• Low-temperature heating systems – ideal for cooperation with modern heat sources, such as heat pumps or condensing boilers.
• Central heating installations – ensures even heat distribution throughout the building.
• Heating systems requiring a constant temperature of the heating medium.

Advantages and benefits

• Flexibility: The ability to choose a pump allows adapting the unit to individual installation needs and budget.
• Precision: The rotary mixer ensures a stable temperature in the heating circuit, which translates to comfort and energy savings.
• Compatibility: Direct connection to Womix flanged manifolds simplifies installation and integration with other system components.
• Easy installation: 250 mm spacing and a set of steel connectors (depending on the version) simplify the installation process.
• Durability: Made of high-quality materials, guaranteeing long life and reliable operation.
• EPP insulation: Provides reduction of heat loss and minimizes the risk of moisture condensation on the surface of the pump unit.
• Expandability: Open space for the pump allows replacing or upgrading the pump in the future without having to replace the entire pump unit.

Remember to purchase additional TBN 50 connectors or spacer connectors (depending on needs) when connecting the unit to C2 125 or C2 150 manifolds. It is also worth paying attention to the possibility of mounting the MP 10 actuator on the mixing valve, which enables automatic temperature regulation.
