The water-injected screw compressor was developed as a water-injected, oil-free screw compressor. For many users, this seemed an interesting solution to provide oil-free air without the complexity of classic dry screw compressors. However, after several years of use, some questioned its long-term performance.
For companies with water-injected screw compressors, we sometimes hear the following questions returned:
♦ How long does the original screw block last? Are there situations where it needs to be replaced early?
♦ How flexible is the compressor’s control range? Does the water-lubricated bearing restrict operation at part load?
♦ How maintenance-sensitive is a water-injected system? And what does that mean for reliability over time?
For those with these questions, a retrofit may offer an interesting alternative.
We offer a retrofit solution where the original screw block and drive of the water-injected screw compressor are replaced with:
♦ an efficient, robust screw block based on industrial applications
♦ a synchronous permanent magnet motor (PM motor) with wide control range and high efficiency
This retains the existing housing, cooling and connection – only the heart of the compressor is renewed.

Our retrofit solution transforms an unreliable installation into a energy-efficient and forward-looking compressor. You keep the housing, coolers and connector – but what really counts, we completely refurbish.
