The XBOXER Heat Exchanger Twin Fan unit shall be manufactured from Aluzinc corrosion resistant steel, with 25mm double skinned infill panels and extruded aluminium frame, giving extremely low noise levels. The unit shall include the following items: - a cross flow heat exchanger block with automatic summer bypass, complete with a condensate drip tray and 22mm drain connection. (Alternatively a condensate pump shall be provided if specified.)
Supply and extract filters (G4 grade pleated filters) Integral infinitely variable speed controls with minimum and maximum adjustment for accurate commissioning, run on timer and facia mounted failure indication, and interface connections for Ecosmart sensors/enablers, dampers and BMS.
The unit shall be constructed with removable panels allowing full maintenance access from the side. The Twin fan unit has left or right hand arrangement in direction of supply air flow. A LPHW heater battery is fitted, pre-piped with a 3 or 4 port valve and actuator assembly. BMS interfaces, fan control and heater battery commissioning control are supplied as part of the Ecosmart control strategy. Heater batteries will require a separate enable signal from either a variable 0-10V BMS signal or the use of a Nuaire ES-LCD control.
