Boiler module - non-mixing with overflow valve - DN 32; without pump IVAR.KS 55ABA

Product detailed description

Non-mixing boiler modules are commonly used in central heating systems where direct temperature control is not required. This model is suitable for residential and commercial buildings, particularly in systems where return water is not mixed with supply water. Installers typically use it in conjunction with boilers and circulation pumps to ensure safe and efficient operation. The module includes essential components such as pressure relief valves, temperature sensors, and isolation valves, making it a compact solution for system integration.

When installing this module, it is important to ensure that the system pressure and flow requirements align with the module's specifications. The brass construction and thermal insulation contribute to durability and system efficiency, while the inclusion of multiple monitoring and control points supports safe operation and maintenance.

Technical parameters

Installation and connection

The module is connected using external 5/4“ M threads, which must be verified for compatibility with the existing piping system. Installers should ensure that all connections are properly sealed and that the module is installed in a location accessible for maintenance. Common installation mistakes include incorrect orientation of the overflow valve or failure to check the integrity of the thermal insulation. It is also important to verify that all included components, such as the two temperature sensors and isolation valves, are correctly positioned and functioning.

Compatibility and accessories

This boiler module is designed to integrate with standard heating systems that use brass components and thermal insulation. It is typically used in conjunction with a circulation pump and boiler control system. Additional components such as expansion vessels or pressure regulators may be required depending on the system configuration. Related products include boiler control units and circulation pump assemblies.

Technical background for designers

The non-mixing design ensures that return water does not mix with supply water, maintaining the desired temperature in the system. The brass CW617N material provides corrosion resistance and mechanical strength, making it suitable for high-temperature environments. The thermal insulation PS helps reduce heat loss and improves overall system efficiency. The integration of multiple monitoring and control points allows for accurate system diagnostics and maintenance. System designers should consider the operating temperature and pressure limits when planning the layout and component selection.

Service and operation

Regular inspection of the overflow valve and thermal insulation is recommended to ensure continued safe operation. The module includes two temperature sensors and isolation valves, which should be checked for proper function during routine maintenance. No specific service intervals are provided in the technical data, but it is advisable to follow the manufacturer's guidelines for periodic checks and cleaning of the internal components.

Frequently asked questions

Can this module be used with a boiler operating at higher than 120°C?
No, the maximum operating temperature is +120°C as specified in the technical parameters. Exceeding this limit may affect the integrity of the components.

Is the overflow valve adjustable?
The overflow valve is a standard component included in the module and is not adjustable. It is designed to operate at the specified pressure and temperature limits.

Can the module be installed in a vertical position?
Yes, the module can be installed in a vertical position as long as the connections are properly aligned and the overflow valve is positioned correctly to allow for proper drainage.

Are the temperature sensors interchangeable with other types?
The temperature sensors included are standard components and are not interchangeable with other types unless specified by the manufacturer in the technical data sheet.
