Control system for air conditioning system

Manufacturer I.V.A.R.

The diversification of uses often crashes against the need for concentrating the hydraulic system components and controls in a single dedicated area: in this respect, the mechanical room is at the same time the heart and the brain of the building, a room to design in the light of the needs and of the user preferences over twelve months.
IVAR substations allow to arrange the mechanical room according to a new concept of space and functionality. These groups give the opportunity to manage multiple thermal zones with different characteristics as truly independent zones in a neat, rational space, thanks to their modular structure and outstanding installation flexibility. 
MULTIMIX substation is suitable to mid-size thermal power plants. MULTIMIX allows to pump heating fluid to different heating zones at different temperatures by independent distribution/booster kits, available with or without mixing valve and equipped with electronic circulator pumps, besides featuring all the necessary monitoring, safety and shut-off accessories. The mixing valve in low-temperature kits can be operated by thermostatic head with remote immersion probe or axial servomotor piloted by electronic controller.

Further details

Flow and return manifolds connecting primary and secondary sides are built in a single component, in 2- or 3-way versions. However, it is possible to connect more manifolds together with simple swivelling nipples.

The presence of a pressure equalizer in the distribution manifolds ensures the hydraulic separation between primary and secondary sides and between the different distribution kits. When equipped with full insulation shell, MULTIMIX can be used also in cooling applications. MULTIMIX can be installed with upwards or downwards distribution kits and it is proposed either in a wide range of pre-assembled boxes or as single components to be assembled depending on the specific requirements.
