Simply the best

The new screw compressor for air-conditioning installations in ships.

MINISCREW from STAL means screw compressors with maximum reliability for the world's shipping lines. Compressors which provide efficient refrigeration under a wide range of climatic conditions.

During the last 20 years - ever since screw compressors began to be used for marine refrigeration installations (where we have long been world leaders) - technical development has made continuous progress. Our new screw compres- sors now operate effectively even i n the lower capacity range for air- conditioning installations. At the same time, they offer the same high efficiency, low maintenance costs and long life as our well-known large compressors.

The secret behind the high relia- bility and low life cycle costs of

MINISCREW is just inside the cas- ing. MINISCREW has only four moving parts, as against 100 or so in a reciprocating compressor.

The screw compressor is a rotating machine with accurately balanced rotors. Consequently, vibration is virtually eliminated. In addition, the new robust design has no sensi- tive operating valves and is much more resistant to liquid carryover.

The strenght of MINISCREW lies in its simplicity.

That is why MINISCREW is simply the best.

We assume full responsibility

Our job is to ensure that your entire installa- tion gives trouble-free operation. We have an organization that provides all the support you need. From planning to main- tenance and service. With STAL as your supplier, you have at your disposal a full range of knowhow and technical resources.

Change to more reliable airconditioning

A worn reciprocating compressor which often causes expensive operating disturb- ances is a drain on your economy and a burden for the crew. Save money and improve crew efficiency. Change to

MINISCREW and your investment will soon pay off!

Small, but strong.
