The challenge: Immediate delivery of a air compressor drive to Cuba

Following successful cooperation, a German manufacturer of industrial gases turned to MENZEL in an extremely urgent emergency: Cuba had lost the country's only air compressor drive to produce oxygen for all hospitals in the island nation. Because human lives were at stake, a fast motor delivery and commissioning was desperately needed.

What added to the difficulty was the fact that during the installation and commissioning on site in Cuba no structural modifications would have been possible. The replacement air compressor motor had to fit perfectly. All details were therefore coordinated directly by telephone between MENZEL's engineers and the plant operator in Cuba.

Our solution: A 6,000 V air compressor motor directly from stock

The customer requested a suitably and adaptable 6,000 V motor, that could cope with the required 3,600 rpm at 60 Hz. Only a handful of suppliers stock large motors with these characteristics. MENZEL maintains one of the largest stock of brand new medium and high voltage motors. As one of the few motor suppliers, the Berlin-based company had a correspondingly adaptable large compressor motor in stock.

In record time, the required connections for cooling water and lubricating oil were moved to ensure a quick and seamless replacement of the old failed motor

Because there are no cargo flights to Cuba, the 6.3ton motor was dismantled for transport on a passenger plane. Once again, MENZEL scored points with its many years of experience in handling international projects. "We are very proud to have helped with our know-how and motors in an emergency such as this."

Motor commissioning under special time pressure

After landing, Menzel employee Henrik Phillip and all the equipment were personally guided through customs by the Cuban Minister of Health. On site, Phillip coordinated the reassembling and commissioning of the new air compressor drive, including assembly of the sleeve bearings.

In the end, only seven days passed between the emergency call in Berlin and the commissioning of the air compressor drive in Cuba by MENZEL.
