Product Description:
The 175Z3437 HVAC drive is produced by Danfoss within the VLT 6000 HVAC Drives series. This variable-frequency converter is intended for controlling fans and pumps in ventilation and chiller circuits across commercial buildings. By converting three-phase input power into a pulse-width-modulated output, it allows building management systems to adjust motor speed in real time. This control helps maintain operating setpoints while reducing unnecessary electrical demand and mechanical stress on connected equipment.
The drive delivers a mechanical capacity of 55 kW / 75 HP, making it suitable for large supply fans and pumps used in commercial HVAC systems. Its power section accepts a 380–460 VAC three-phase input, allowing connection to common industrial power systems without an autotransformer. The Compact NEMA 1 enclosure provides protection against accidental contact with internal components and supports installation in conditioned electrical rooms. The drive uses control algorithms intended for fan and pump profiles, allowing its output to respond efficiently to changing flow or pressure requirements. Operators can program and monitor the inverter through an integrated Local Control Panel with start and stop keys, a backlit display, and parameter navigation. The unit has no built-in radio-frequency interference filter, so external electromagnetic compatibility measures may be required where strict emission limits apply.
The drive uses uncoated circuit boards, so its enclosure should remain free of corrosive vapors, excessive humidity, and conductive airborne contaminants. It has no fieldbus option, leaving control and status signaling to hardwired inputs, outputs, or the Local Control Panel. The internal power stack follows the standard unit configuration used for this drive rating. This arrangement provides the core power-conversion and motor-control functions without an installed network communication module. The assigned site identifier is Graham, which associates the unit with its intended facility or application location. Available accessory provisions permit compatible additions to be installed when the application requires expanded control or communication functions.
