IVAR SAT
IvarSAT is the solution for direct metering of heat and domestic hot water in central heating systems without centralised production of domestic hot water (DHW): in fact, thanks to IvarSAT the production of DHW takes place instantly and is given priority at the level of the individual housing unit. IvarSAT is available in three families: the “H” family with direct delivery, suitable for high temperature heating systems; the “LE” family equipped with mixing valve and booster pump, suitable for radiant systems, and the “HLE” family, which integrates two separate deliveries, one direct without booster and one mixed with booster. Domestic hot water temperature is controlled by a thermostatic anti-scald mixer (max 50 °C). For the “1” models there is the provision for a disconnect upstream of the mixer without limitation of the delivery temperature. IvarSAT is also available with a built-in circulation pump (“R” models). The unit also includes a heat meter, a domestic cold-water meter and heating management devices such as thermostats and electrothermal heads. To meet the needs of construction sites, IvarSAT can also be supplied as an installation template with functional components provided separately.
IVAR-SAT H
Heating power (*): approx. 10 kW
Domestic hot water output (**): approx. 32 kW - production of approx. 12 l/min of domestic hot water at 48°C with mains input at 10°C
(*) temperature difference = 10°C and pressure differential at the ends of the module = 200 mbar
(**) pressure differential at module ends = 150 mbar and boiler temperature = 60°C
IVAR-SAT LE
Heating power (*): approx. 7 kW
Domestic hot water output (**): approx. 32 kW - production of approx. 12 l/min of domestic hot water at 48°C with mains input at 10°C
(*) temperature difference = 8°C and WILO4 circulator
(**) boiler temperature = 60°C
IVAR-SAT HLE
Heating power (*): approx. 7 kW (low temperature part)
Heating power (*): approx. 5 kW (high temperature part)
Domestic hot water output (***): approx. 32 kW - production of approx. 12 l/min of domestic hot water at 48°C with mains input at 10°C
(*) temperature difference = 8°C and WILO4 circulator
(*) temperature difference = 10°C and pressure differential at the ends of the module = 200 mbar
(**) boiler temperature = 60°C
PLUS
• Available in the following versions: high temperature (IVARSAT H), low temperature (IVARSAT L/LE), combined (IVARSAT HL/HLE)
• Can be equipped with domestic hot water recirculation fittings
• Flush- or wall-mounted installation
• Elect
IvarSAT
IvarSAT satellite modules can be divided into three groups, which are different in the type of heating systems each of them is suitable to supply:
- Family H, suitable to high-temperature systems: one heating circuit with zone valve;
- Family L, suitable to low-temperature systems: one heating circuit with three-way mixing valve, zone valve and variable-speed booster pump;
- Family HL, suitable to high- and low-temperature systems: one heating circuit with three-way mixing valve, zone valve and variable-speed booster pump; a second heating circuit with zone valve.
Among the several variants, additional features are available such as domestic hot water recirculation circuit and a "direct" second outtake for non-mixed domestic hot water. IvarSAT is available either on frame or already housed in recessed or wall-hung box. As an alternative, it is possible to purchase the connection template and the hydraulic modules to be installed after the test. As concerns measurement devices, it is possible to choose among different kits suitable to any type of reading (direct, central via M-BUS or central via RADIO network). All devices are MID compliant and feature supplementary metrology marking.
