HUADA SED-75+ 55 kW Air-Cooled Two-Stage Permanent Magnet VSD Screw Air Compressor

SED-75+ at a glance

The SED-75+ is a 55 kW two-stage, oil-injected PM VSD compressor for factories building a shared production-line air supply. Air delivery is 12.5 m³/min at 0.8 MPa, with a G2 outlet and a unit size of 1800 × 1250 × 1600 mm.

Its G2 outlet and pressure-specific output figures provide a basis for reviewing a production-line upgrade. Check both average consumption and short demand peaks, then coordinate compressor capacity with storage and downstream treatment.

01   Product advantages

HUADA SED-75+ 55 kW air-cooled two-stage PM VSD screw air compressor, shown in blue-gray with orange trim.

02   Technical specifications

Air-delivery values correspond to the individual pressure points shown; they are not a VSD minimum-to-maximum flow range. Motor speed is a specification reference, not a stated speed range. Confirm the required pressure configuration and site conditions when ordering, and compare noise levels under equivalent measurement conditions.

03   Check the fit for your site

Pressure and demand: For a shared production-line network working across multiple shifts, provide average and peak air consumption, operating hours and pressure losses to the point of use. Use 12.5 m³/min for the 0.8 MPa duty point.

Electrical and cooling provision: The motor power is 55 kW and the power supply is 380 V / 3-phase / 50 Hz. Review power availability together with room ventilation and the hot-air exhaust route for the planned operating hours.

Handling and connections: Allow for the 1800 × 1250 × 1600 mm cabinet, 1440 kg unit weight and G2 outlet. Obtain the installation drawing and add the required access, service and ventilation clearances.

Air quality and site conditions: Select the receiver, dryer and filters for the required moisture, particulate and oil limits. Report high temperature, high humidity, severe cold or heavy dust so that the proposed configuration can be reviewed for the actual environment.

06   Frequently asked questions

What airflow does the SED-75+ provide at different pressures?

Air delivery is 12.8 m³/min at 0.7 MPa, 12.5 m³/min at 0.8 MPa, 9.6 m³/min at 1.0 MPa and 8.6 m³/min at 1.2 MPa. Specify the required pressure configuration when requesting a quotation.

How does the compressor respond when production demand changes?

Current-vector VSD control adjusts the permanent magnet motor speed in response to demand, while the cooling-fan drive also uses variable-frequency control. Select the operating configuration around the required pressure and the plant load profile.

Is 1500 rpm the full VSD speed range?

1500 rpm is the motor-speed specification. It is a single reference value, not a minimum-to-maximum VSD operating range. Request the operating limits for the selected machine configuration when these are needed for the project.

Does VSD guarantee the same energy saving at every site?

Savings depend on the demand profile, operating pressure, running hours and the compressor system being compared. Review measured air demand and the expected loading pattern when assessing operating cost.
