For rising main systems, IVAR proposes thermoregulation and heat consumption accounting kits consisting of lockshield, valve and thermostatic head or modulating electronic motor, plus a wide range of EN 834-compliant heat cost allocator models, suitable to different reading methods and featuring additional options.
IVAR thermostatic valves are available in straight, angle, coaxial or reversed body geometries, with iron-pipe or copper-pipe connections. They are also available with or without flow rate pre-selection insert at 6-positions. Several IVAR thermostatic valves (i.e., thermostatic head + valve) feature EN 215-compliance Keymark, which defines them as low-inertia systems. As an alternative to traditional thermostatic heads, EQUICALOR® is an advanced thermoregulation system based on flow rate modulation, suitable to manage different thermal zones with daily/weekly program.
Heat cost allocators are available in base models with one or two temperature sensors. This version is particularly indicated for systems characterised by a low number of apartments, since it only allows direct reading device by device. RADIO models give the possibility to collect consumption data through a network made by bi-directional antennas, and possibly to perform remote reading by adding two GSM modems. Finally, with "Walk-By" models all the consumption data are sent to a single mobile data collector, which is part of the equipment of the meter reading service. The data acquisition often works even from the outside, without the need for the person in charge to enter the building.
