Mixing set PrimoBox AZB 351 in cabinet, without mixing, rotary valve with actuator ARM 141, thermostatic valve ATM 561 7635100

Mixing sets PrimoBox AZB – a compact solution for efficient heating

PrimoBox AZB mixing sets are ready-to-install, compact hydraulic systems designed to distribute heat from a single source to two or three heating circuits. They allow both direct supply of circuits with the source medium temperature and mixing it with return water to obtain a lower temperature. This is an ideal solution for installations where different levels of thermal comfort are required in individual zones of the building.

PrimoBox AZB 351, equipped with a rotary valve with ARM 141 actuator and ATM 561 thermostatic valve, offers flexibility and precision in temperature control. The set is factory sealed and has thermal insulation minimizing heat loss. This ensures not only energy efficiency but also ease of use and installation.

Construction and application

The PrimoBox AZB 351 set consists of a cabinet containing a manifold with a built-in hydraulic coupling, shut-off valves with thermometers, a Grundfos UPM3 AUTO 15-70 circulating pump, and the aforementioned valves – a rotary valve with ARM actuator and ATM 561 thermostatic valve. The design allows easy connection with other AHB sets using the AJB connector, expanding the possibilities of the heating system.

Application:

• Central heating installations with division into temperature zones.
• Underfloor heating systems.
• Heating of residential and commercial buildings.
• Modernization of existing heating installations.

Key features and benefits

• Compact design: saves space and simplifies installation.
• Factory seal: guarantees reliability and safety of the installation.
• Thermal insulation: minimizes heat loss and increases energy efficiency.
• Versatility: possibility of configuring different heating circuits – direct and mixed.
• Precise regulation: ATM 561 thermostatic valve ensures accurate maintenance of the set temperature in the heating circuit.
• ARM 141 actuator: enables remote control of heat flow in the heating circuit, which translates into greater comfort and the possibility of integration with smart home systems.
• Maximum heating power up to 35 kW: allows use in installations of various power.
• 3/4 inch connections: standard size facilitating integration with existing hydraulic installations.
• Set weight (13-22 kg): suggests a solid construction and the use of durable materials.

The PrimoBox AZB 351 set is an investment in the comfort, efficiency and reliability of the heating system – both for professional installers and end users.
