DZM 1200 VSD+ 3002615413 3Ph 380-460 V 50/60 Hz

Atlas Copco DZM 1200 VSD+ – central vacuum system with three claw pumps

The DZM 1200 VSD+ – listed by Atlas Copco as DZM 1200 VSD+A – combines three claw pumps of size DZS 400, each with its own variable speed drive, in a sound-insulated enclosure. The brochure states a nominal displacement of 24 to 1170 m³/h, an ultimate pressure of 150 mbar(a) in continuous operation and a rated power of 33 kW. The system measures 1460 × 1575 × 1982 mm (L × W × H); the operating instructions state a weight of 1500 kg. Inlet and outlet are flanged, DN 100.

Plug-and-play instead of individual piping

The system includes one common inlet manifold and one common exhaust manifold as the interface to the customer's network. According to Atlas Copco, this considerably reduces complexity and installation costs compared with other central systems. Each pump is accessible without stopping the system.

Control

A pressure sensor in the inlet line measures the network pressure; the controller keeps it within the programmed pressure band. One variable-speed pump follows the changing demand; the others are switched on or off depending on the volume flow required. The operating hours are balanced between the pumps in the process.

Version of the DZM 1200 VSD+

Ehrler & Beck lists the DZM 1200 VSD+ under part number 3002615413 for 380 to 460 V mains voltage at 50 or 60 Hz.
