IN LINE MIXED FLOW DUCT FANS AND HOT WATER COIL HEATING System fan (from model 25) and a MBW water coil installed on the discharge side of the fan. MBW water coil (advisable to install on the inlet side of the fan). + MBW WATER COIL MBW water coil type - Range of connection diameters, 1-5 mm. - Galvanised steel housing. - Hot water coil with copper pipes and aluminium fins. - Removable side for maintenance purposes. - Can be mounted horizontally or vertically. - Connections with watertight seals. - Connection must be made between the coil and the hot water circuit. - Maximum pressure: 1 bar. - Maximum temperature: 1ºC. Shut-off valves must be installed on each water connection, so that the unit can be isolated if necessary (for cleaning filters, repairs, etc.) without the need to drain the entire circuit. We recommend installing a filtration box with a filter (MFL-F + MFR) at the input to the unit, to capture water borne debris. In those installations where MIXVENT HEATING system is required it is convenient to use filter boxes MFL to protect the coil from the dirt.
