boiler modules and assemblies IVAR.KS

Boiler modules and assemblies IVAR.KS provide the hydraulic connection between the heating boiler and individual circuits via a horizontal distribution manifold DN 32 (connection 5/4" F x 5/4" F). The IVAR.KS system offers both unmixed modules and mixed variants (e.g. MIX 3) with a 3-way mixing valve and a 230 V actuator.

Several assemblies also include a bypass valve, which protects the circulation pump from running against a closed valve when there is low demand in the circuit. The circulation pumps are from the DAB EVOSTA2/EVOSTA3 range, and their output is selected according to the required flow rate of the given circuit.

Frequently Asked Questions

• What is a bypass valve and why does the assembly include it? It protects the circulation pump from damage when running against a closed valve, when heat demand in the circuit is low or temporarily shut off.
• What does the designation MIX 3 mean? It is a mixed assembly with a 3-way mixing valve and a 230 V actuator, which regulates the temperature of the heating water in the connected circuit.
• Which manifold do the IVAR.KS assemblies use? A horizontal distribution manifold DN 32 with a 5/4" F x 5/4" F connection, onto which the modules are mounted side by side.
• Can an unmixed and a mixed module be combined on one manifold? Yes, individual IVAR.KS modules are selected separately for each circuit depending on whether it requires temperature control.
