Screw compressor monitoring

Compressed air: the fourth utility

Compressed air often accounts for 10–30% of plant electricity. Monitoring compressors and distribution is one of the highest-ROI predictive maintenance programs.

Typical problems

Air leaks

Industry studies show 20–35% of produced air is lost through leaks. SDT270/SDT340 survey the plant; LEAKChecker logs each leak with size and cost for prioritized repair.

Compressor bearings

Rotors at 3000–12,000 rpm need clean oil and stable temperature. SDT340 trends bearing points over 6–12 months to schedule replacement before failure.

Lubrication with LUBExpert

Grease-lubricated bearings get exact doses — avoiding overheating from over-greasing and dry running from under-greasing.

Artesis EMCM on the drive

Motor-current analytics detects load changes from worn rotors, clogged filters, coupling misalignment and electrical defects — without machine-mounted sensors.

Energy program

1. Leak audit (SDT270/LEAKChecker)
2. Condition routes (SDT340)
3. Continuous drive monitoring (Artesis EMCM)

Typical results: 15–25% lower air-related electricity, 65% fewer unplanned compressor stops, payback in 6–12 months.
