Mixing set PrimoBox AZB 255 in cabinet, 2x rotary valve with ARM 141 actuator 7625500

PrimoBox Mixing Sets – a compact solution for efficient heating

The PrimoBox AZB 255 mixing set is a ready-to-install hydraulic solution enclosed in an aesthetic and compact cabinet. Designed to separate the heat source from two heating zones, it allows supplying them with a medium at the appropriate temperature – both directly from the boiler and after mixing. This is an ideal solution for installations with a capacity of up to 35 kW, where efficiency, space saving and ease of installation are important.

Construction and application

The PrimoBox AZB 255 set includes all the necessary elements for the proper functioning of the heating system: a manifold with a hydraulic coupling, shut-off valves with thermometers, circulation pumps and thermal insulation minimizing heat loss. Thanks to factory-tested connections and a prefabricated design, installation is quick and easy – saving time and installation costs. This set can be used in installations with various heat sources and heating zones, ensuring optimal operating parameters of each circuit.

Key features and benefits

• Compact design: The cabinet with dimensions of 450 x 500 x 160 mm allows installation even in limited boiler room space.
• Factory tightness: Each set undergoes rigorous leak tests before leaving the factory, guaranteeing trouble-free operation.
• High efficiency: The hydraulic coupling ensures proper medium flow and optimal pump operation in each heating circuit.
• Versatility: The possibility of connecting to AHB sets via the AJB connector expands the functionality of the system.
• Rotary valves with ARM 141 actuators: Enable precise temperature control in individual heating zones. The valves have a nominal diameter of 3/4 inch (20).
• Durable construction: Made of high-quality materials and protected by painting, ensures long-term reliability.
• Easy installation and maintenance: The prefabricated design and shut-off valves with thermometers facilitate the installation and servicing of the system.

The PrimoBox AZB 255 set is an investment in the comfort, savings and reliability of the heating system – both for professional installers and end users.
