This unique modular system allows the flexibility to handle any application. These versatile MX blowers may be used for upflow, downflow, or horizontal left or right applications. They may be combined with cased coils to function as a cooling only unit or with a heat pump including electric heat for 1 and 3 phase applications. The MX blower and 4HK electric heater kits can be used as stand alone electric furnaces. Using standard ECM (X13 style) motors, system matches provide higher SEER/HSPF ratings than standard blower models at attractive price points.

All heaters include nickel-chromium elements with a 5-year limited warranty on 1 Ø heating elements and 1 year limited warranty on 3 Ø heating elements.
