Mixing set PrimoBox AZB 301 in cabinet, 2x non-mixing, thermostatic valve ATM 561 7630100

Compact solution for efficient heating

The PrimoBox AZB 301 mixing unit is a ready-made, prefabricated hydraulic solution in a cabinet, designed to separate the heat source from two heating zones, with the ability to regulate the temperature in one of them. It is ideal for both new installations and for modernizing existing heating systems. The device allows for obtaining different supply temperatures for the heating circuits, ensuring thermal comfort and optimizing energy consumption.

Construction and application

PrimoBox AZB 301 utilizes a hydraulic decoupling unit, which minimizes the impact of circulation pumps on the heat source and guarantees independent operation of individual circuits. Two circuits operate without mixing, delivering medium directly from the heat source, while the third circuit is equipped with an ATM 561 thermostatic valve, enabling precise temperature regulation in the range of 20-43°C. The unit is factory-tested for hydraulic and electrical tightness, ensuring reliable operation. Installation is simple and quick – the device is designed for mounting on or in the wall near the heat source.

Advantages and benefits

• Compact design: Reduces space occupied in the boiler room – up to 80% of the boiler room in one cabinet!
• High efficiency: Hydraulic separation of the heat source from the heating circuits optimizes the operation of the entire system.
• Precise regulation: The ATM 561 thermostatic valve allows for accurate temperature setting in one of the circuits.
• Easy installation: Prefabricated construction speeds up installation and reduces labor costs.
• Safety: Factory-tested tightness of connections guarantees trouble-free operation.
• Versatility: Possibility of connection with AHB sets via AJB connector expands the functionality of the system.
• Durability: Made of high-quality materials ensures long device life.
• Pump operation optimization: Hydraulic decoupling reduces the load on circulation pumps, extending their life and reducing energy consumption.

PrimoBox AZB 301 is an excellent choice for both professional installers looking for a reliable and easy-to-install solution, and for end-users who want thermal comfort and energy savings. The set is compatible with water and water-glycol mixtures with a maximum concentration of 30%. The maximum operating pressure is 4.5 bar, and the maximum medium temperature is 95°C. Connections from the boiler side and the installation side are G¾ inch. The set includes Grundfos UPM3 Auto 15-70/130 mm pumps and an ATM 561 thermostatic valve with a flow rate of Kvs 2.5 m³/h.
