Separation unit PrimoBox AHB 622 in cabinet, 2 Grundfos UPM3 Auto pumps, thermostatic valve ATV 213 (45°C) 7662200

PrimoBox AHB Separation Unit – a comprehensive solution for your installation

The PrimoBox AHB 622 separation unit is a ready-made, prefabricated solution that allows you to connect two independent heat sources into a single coherent heating installation. It is ideal for situations where you want to combine, for example, a wood-burning fireplace with a water jacket with a traditional gas or coal boiler. Its compact design and factory-tested leak-proof connections guarantee quick and trouble-free installation.

The AHB unit allows for comfortable connection of an open-loop installation (e.g. fireplace) with a closed-loop installation (e.g. boiler) thanks to the use of a high-quality plate heat exchanger. This solution ensures optimal energy utilization and efficient heating of your home. The whole is enclosed in an aesthetic and durable cabinet, which protects the components and improves the appearance of the boiler room.

Construction and functionality

The set includes key elements necessary for the proper operation of the installation:

• Plate heat exchanger: Provides efficient heat exchange between two circuits, allowing connection of different heat sources with different parameters.
• Thermostatic valve ATV 213 (45°C): Controls the temperature of the heating medium, ensuring optimal operating conditions of the installation and protecting against overheating. Setting to 45°C is a compromise between efficiency and system safety.
• Two Grundfos UPM3 Auto pumps: Ensure adequate flow of the heating medium in both circuits, adjusting their operation to the current heat demand. The Auto function allows automatic adjustment of the pump performance to the operating conditions, which translates into energy savings.
• Protective cabinet: Protects components from mechanical damage and external factors, and also improves the aesthetics of the installation.

Thanks to its compact dimensions (450 mm x 500 mm x 160 mm), the PrimoBox AHB set takes up little space in the boiler room, which is particularly important in the case of limited spaces. Prefabrication means that most of the installation work has already been carried out at the factory, which significantly reduces installation time and minimizes the risk of errors.

Advantages for installers and users

• Quick installation: Ready-made solution saves time and reduces installation costs.
• High quality: Components from renowned manufacturers guarantee reliable operation and long life.
• Versatility: Possibility to connect different heat sources – fireplace, gas boiler, coal boiler, etc.
