Axial air heaters
High-efficiency fan motor assembly
Silent FMA featuring an aluminium epoxy polyester-coated airfoil propeller to ensure the best compromise between air flow efficiency and acoustic comfort. The ROTOREX design (windings inserted in the fan hub) keeps the motor cool to ensure that it operates at optimum efficiency. Three versions are available : THREE-PHASE 2 speed (230/400V - 3Ph - 50Hz) (accessory LS/HS switch) SINGLE PHASE 1 variable speed (230V - 1Ph - 50Hz) (accessory 5-speed autotransformer) CORROBLOC version guaranteed to withstand corrosive environments.
Fan motor assembly equipped with a powerful HEE EC (electronically commutated) motor. These EC motors (single-phase 230V - 1Ph - 50/60V drive) will be progressively controlled by the 0-10 V signal, to ensure acoustic comfort and air flow efficiency and to optimise consumption of electricity. A shunt can be used to operate the air heater at maximum speed.
CORROBLOC FMA IP65/700-hour salt spray test
• Elegant galvanised steel casing, pre-coated with RAL 7035 (light grey) paint (stainless steel version available on request). • Condensate drain pan built-in for cooling applications, featuring an antibacterial design (perforated bottom) and quick-release fitting (diameter 1'1/4). • Intake section optimised for improved air flow performance and acoustic comfort level. • Advantages: - Its classic design means that it can easily blend into the architecture of the installation site. - No need to add an unsightly condensate drain pan. - Condensate pipes quick and extremely simple to connect, without any need for a clamp, (1'1/4 diam. quick-release fitting).
