Duct-IN manufacture air conditioning plenum boxes to suit the full range of Mitsubishi Electric ducted fan coil units. 

Duct-IN have the expertise to manufacture galvanize steel plenums which conform to DW144 to the engineer and architect’s needs. Multiple options are available to customers which can include top, bottom, either side entry discharge or return, diameter of spigot and with the option for round or oval spigots. The plenums can be internally or externally lagged, this can prevent moisture build up and has sound deadening properties. 

A big trend with architects at the minute is the industrial feel with open ceilings, a galvanised steel plenum is perfect in keeping as opposed to ABS plastic plenums. Another benefit of working with Duct-IN is we can provide a powder coating service, allowing plenums to be sprayed to any colour required by a client. This helps to blend in with other HVAC services and makes it more aesthetically pleasing for the client. With multiple options for our customers and owners who have years of experience, this makes Duct-IN the most flexible air conditioning plenum manufacturer on the market.
