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

PrimoBox AZB 255 with hydraulic coupling - mixing set of 2 circuits

PrimoBox AZB 255 is a prefabricated hydraulic solution mounted in a cabinet, which connects two heating circuits with an integrated hydraulic coupling. Each circuit uses an ARV mixing valve with an ARM 141 ProClick actuator and a flow coefficient Kvs = 3.6 m³/h. The set is suitable for installations with a maximum output of 35 kW

Application

• Closed systems where separation and control of two heating circuits is required
• Systems where one circuit requires temperature mixing and the other circuit operates without mixing
• New design-compact boiler rooms - saving space and combining functions in one box
• Modernizations where it would be time-consuming to replace many system components

Advantages and distinctive features

• Comprehensive solution in one cabinet - valves, actuators and hydraulic coupling
• Prefabricated kit - reduces assembly time and installation errors
• Temperature control in both circuits thanks to ARV valves
• Insulated design and compact shape - saves space and reduces heat loss
• High independence of circuits thanks to coupling

Installation and operation tips

• Mount the kit in a location that allows easy access to valves and pumps
• Before commissioning, bleed the entire system and check for leaks
• Set the actuator movement stops to the correct positions
• Avoid operating outside the acceptable pressure and temperature ranges
• Regularly check the condition of valves and the tightness of hydraulic connections
