MECO vapor compression stills feature the GII Centurbo™ Compressor. Its directly driven variable-speed motor eliminates belt drives, gear transmissions and flex couplings. Bearings are cooled with air and lubricated intermittently with oil. There’s no recirculating oil system with filters, coolers, pumps, plumbing, valves and instrumentation. No oil and filter changes. Maintenance goes down. Efficiency and reliability go up. You get longer runtime and fewer headaches.
