PrimoBox AZB 205 mixing set in cabinet, without mixing, rotary valve with ARM 141 actuator

PrimoBox AZB 205 mixing set with hydraulic coupling

PrimoBox AZB 205 is a compact hydraulic kit that integrates two circuits in one cabinet: - circuit without mixing (direct) - circuit with ARV mixing valve and ARM ProClick actuator The kit also comes with a hydraulic coupling, which ensures pressure stability between circuits The maximum power of the kit is **35 kW**

Application

• Heating systems with the need to separate circuits
• Systems requiring temperature control in one of the circuits
• Upgrades or new boiler plants where a quick and clean hydraulic solution is required
• Use in systems with pumps, where hydraulic separation increases the stability of operation

Advantages and distinctive features

• Complete prefabricated kit in a cabinet - saves assembly time
• Hydraulic coupling for stability between circuits
• Mixing circuit with ARV valve and ARM ProClick actuator - ease of control
• Aesthetics and orderliness of the installation thanks to integrated design
• High usability in retrofits and new installations

Installation and operation tips

• Mount the kit in a position that allows access to the valve, pumps and coupling
• Before commissioning, bleed the installation and check for leaks
• Set the mixing valve actuator correctly - movement limiters 0-10 or 10-0
• Avoid exceeding the permissible parameters (pressure, temperature)
• Regularly check the condition of valves, pumps and tightness of connections
