AL-KO AIR HEATER / AIR COOLER INDUSTRY
3.
Product description
AL-KO air heaters / air coolers of the INDUSTRY series consist of a stable, self-supporting steel sheet housing which is
sendzimir-galvanised and has additional powder coating. A galvanised, adjustable diffusion grid with slats is installed
and adjusted at the air outlet as a standard fitting. A maintenance-free axial fan ensures low-noise operation. The drives
of the AL-KO air heaters / air coolers are external rotor motors. They have a permanently lubricated deep-groove ball
bearing and the fan forms a single unit with the rotor. A heat exchanger for air heating / cooling is installed in the hous-
ing next to the fan. This is implemented as a finned heat exchanger depending on the type (Type N / NF made of Cu /
Al, Type H / HF made of FeZn / FeZn, Type D / DF made of FeZn / Fe, Type S / SF made of FeZn / Fe) or as an electrical
heating register (Type EL made of V4A). The air heating / air cooling devices can be extended by various attachment and
electronic accessories.
Our products are subject to continuous quality control and comply with the relevant, currently valid regulations.
