The helical tubular resistance consists of a ceramic tube with a high degree of thermal dissipation and mechanical resistance and which supports a winding spiral resistive wire.
Especially suitable for motors without gearbox (GEARLESS) due to its low noise (silent).
Covering the tube and both sides we use a galvanized sheet steel box properly perforated for proper ventilation. This box complies with the IP20 protection standard.
