CALOR-MET - Счетчик тепла

CALOR•MET system for heat indirect metering Temperature control and metering assure controlling independence and transparency in measuring consumption in centralised heating installations in condominium buildings.‎ In vertically distributed installations, heat cost allocators are used for metering which - programmed depending on the features of the heating appliance - count units proportional to consumption.‎ IVAR offers a comprehensive range of cost allocators compliant with the EN 834 standard and programming, installation, data centralisation and reading accessories.‎ Temperature control is carried out by heating appliance valves such as low thermal inertia thermostatic valves compliant with UNI EN 215 or the EQUICALOR® electronic multi-zone system.‎ Calor-Met 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.‎ Technical features Head adjustment range: 6.‎5-27.‎5 °C (T 1000); 6.‎5-28 °C (T 5000/DH 01) Head hystheresis: 0.‎65 K (T 1000); 0.‎5 K (T 5000/DH 01) Head response time: 22 min (T 1000); 23 min (T 5000); 10 min (DH 01) Max heating fluid temperature: 100 °C Max differential pressure across the thermostatic valve: 0.‎2 bar Max static working pressure: 10 bar Heat cost allocators Battery type: lithium Battery life: 10 years Temperature sensor range: 0-105 °C Materials Valves and lockshields: - Body: nickel-plated CW617N brass - O-rings: peroxide EPDM - Valve flow rate pre-selector (where present): PPA Thermostatic heads: - Knob: ABS - Thermostat: wax expansion (T 1000) or liquid expansion (T 5000 or DH 01) - Ring nut: CW617N brass - Connection: M30x1.‎5 Further info from manufacturer on CALOR-MET IVAR
