Energy-Saving RM Screw Air Compressor

As a dedicated China supplier, DECHUAN builds the Energy-Saving RM Screw Air Compressor to reduce utility expenses across automated production lines. Featuring V-Shield O-ring joint sealing and an IP66 oil-cooled PM drive motor, it eliminates fluid leakage and maintains air header pressure stability within ±0.1 bar during peak operating shifts.

Rotary Screw vs. Conventional Piston

Piston compressors rely on reciprocating valves that generate significant heat and wear, requiring frequent cooldown stops. The rotary screw mechanism provides constant, smooth air compression without friction spikes.

Multi-Compressor Networking with Integrated Luminance Controllers

Sequencing multiple air compressors traditionally requires buying an external master control panel. The Energy-Saving RM Screw Air Compressor controller includes built-in sequencing logic that links up to four compressors over RS485 communication lines.

Noise Immunity: 

Shielded control boards prevent electromagnetic interference from interrupting controller logic.

Process Tracking: 

Transmits pressure, temperature, and service warnings to facility monitoring systems.

Interface Clarity: 

The color screen gives technicians direct access to pressure settings and sequence timing.

Frequently Asked Questions

How does the variable speed drive respond to sudden load changes?

The IE5 permanent magnet VSD alters motor speed across a 40% to 100% operating range. When pneumatic machinery starts, the Energy-Saving RM Screw Air Compressor's controller increases motor speed to hold system pressure within ±0.1 bar.

What causes oil carryover levels to rise above 3–5 ppm?

Elevated oil carryover usually indicates a saturated air-oil separator element or degraded fluid caused by excessive operating heat. Replacing the separator element restores fluid separation below 3–5 ppm.

Why is the horizontal cooler constructed without welded joints?

The non-welded horizontal cooler uses expansion joints that absorb thermal movement during heating and cooling cycles, preventing weld fatigue and header oil leaks.
