55kW Skid Mounted High Pressure Fixed Speed Single Stage Air Compressor

Elily 55kW skid-mounted high-pressure fixed-speed single-stage rotary screw air compressor adopts an all-in-one integrated skid structure with customizable working pressure ranging from 10 bar to 15 bar. Equipped with a heavy-duty high-pressure fixed-speed airend, the unit requires no complicated installation or civil engineering work. It serves as an excellent replacement for conventional high-pressure piston compressors for modern industrial high-pressure air supply systems.

I. Professional High-Pressure Fixed-Speed Structure — Durable & Low Maintenance

Configured with a customized 55kW high-pressure fixed-speed airend, the whole machine including internal pipelines and valve components adopts reinforced 1.6 MPa grade design, supporting stable long-term continuous operation under 10–15 bar working pressure.

Adopting standard fixed-speed operation without complex variable-frequency electronic components, the equipment features a simple mechanical structure and extremely low failure rate. Compared with traditional high-pressure piston compressors that require frequent replacement of valve plates and piston rings, this screw compressor greatly reduces daily maintenance workload. It cuts long-term maintenance costs by up to 60%, perfectly adapting to 24-hour uninterrupted high-pressure air supply demands for industrial factories.

II. Integrated All-in-One Skid Design — Plug-and-Play & Time-Saving

This 55kW high-pressure compressor integrates the main compressor host, high-pressure air tank, refrigerated dryer, two-stage precision filtration system, and intelligent control cabinet onto one unified heavy-duty skid base.

All internal piping layout, circuit connection, overpressure testing and air tightness inspection are fully completed before factory delivery. The unit can be directly placed on flat ground for use, with on-site installation and commissioning finished within half a day. Compared with traditional split high-pressure air stations, the integrated design saves 40% workshop floor space and reduces installation time by 70%.

III. Complete Safety Protection System — Adaptable to Harsh Working Conditions

The machine is equipped with a full set of industrial safety protection functions, including high-temperature protection, overpressure protection, phase loss protection, overload protection, phase sequence protection and voltage fluctuation protection.

The control cabinet adopts professional dust-proof and moisture-proof structure design, ensuring stable operation in dusty, high-temperature and humid industrial environments. It supports reliable 24/7 unattended automatic operation, delivering safe and consistent high-pressure compressed air output.

Logistics and Delivery

The compressor unit is packed in heavy-duty fumigation-free wooden crates lined with shock-absorbing padding, fully suited for long-distance land and ocean transportation. Before shipment, pressure inside the air receiver and all pipelines is completely released, while all connection ports are tightly sealed for anti-collision and dust protection.

For domestic customers, we arrange dedicated trucks for door-to-door delivery to your plant, with auxiliary hoisting and on-site positioning support available.

For export orders, we accept FOB and CIF trade terms and supply a full suite of customs clearance paperwork, including pressure vessel inspection certificates and CE certification documents. We maintain mature, stable shipping routes covering Southeast Asia, Europe and the Americas, delivering a smooth one-stop logistics solution for all overseas buyers.

FAQ

Q: Is the working pressure of this 55kW fixed-speed model adjustable from 10 bar to 15 bar?

A: Yes. Custom pressure configuration from 10–15 bar (1.0–1.5 MPa) is available. The unit is designed with a maximum pressure rating of 16 bar (1.6 MPa), so the output pressure can be precisely calibrated to match your on-site compressed air demands.

Q: Do I need to buy an air receiver tank, refrigerated dryer and filters separately?

A: No. This is an all-in-one integrated unit pre-installed with all essential air treatment parts. Simply connect the power supply and air pipeline, and the machine can be put into operation directly.

Q: Does this skid-mounted compressor need a dedicated concrete foundation?

A: It does not require special foundation construction. Equipped with a robust integrated skid frame and anti-vibration pads, the machine can be placed and run smoothly on any flat, solid ground.

Q: Is 24-hour continuous high-pressure operation available?

A: This compressor is engineered for heavy-duty industrial high-pressure working conditions. It features outstanding heat resistance and overload resistance, enabling non-stop year-round operation (365 days).

Q: How to select between this fixed-speed high-pressure model and the VFD variable frequency version?

A: Pick this fixed-speed model if your factory has stable, consistent 24/7 air consumption and cost control is your top priority. Opt for the variable frequency model if your air demand fluctuates sharply, as it delivers remarkable long-term power savings.

Q: Can special non-standard voltages for overseas projects be customized?

A: Custom overseas voltage specifications including 415V, 460V are supported. We can also supply the full range of certification documents required for customs clearance and local market access.
