DZTYP Series
DZTYP Series Low-Speed Direct-Drive Permanent Magnet Motor System
A low-speed high-torque permanent magnet motor plus intelligent drive cabinet, sold as one system and mounted where the gearbox used to be.
A conventional cooling tower drive puts an induction motor outside the tower and runs a drive shaft through to a gearbox inside it, which turns the fan. DZTYP replaces that whole chain: the direct-drive permanent magnet motor mounts in the gearbox position and drives the fan directly. The mechanical linkage, and its losses and maintenance, are gone.
The motor is controlled by an intelligent variable-frequency cabinet with soft anti-reverse protection after a power failure, stop or fault alarm, regenerative braking, automatic heating against condensation at low ambient, automatic cooling at high ambient, and over-torque, over-voltage and over-current protection.
IP67 and class H insulation are there for a reason — this machine sits inside a cooling tower, in a permanently wet, warm airstream.
