JP Sauer & Sohn Maschinenbau - Offshore Compressors

JP Sauer & Sohn Maschinenbau (Sauer & Sohn), with headquarters in Kiel, Germany, offers a complete range of highly developed, reliable and economical compressors for the shipping and naval industries. Products include air-cooled compressors, water-cooled compressors and screw compressors.

Air-cooled compressors

Two-stage, air-cooled compressors for main start air have been used for several decades on vessels including coastal ships, offshore supply boats and tugs, providing excellent reliability as well as simple maintenance.

In the early 1970s, Sauer & Sohn introduced the first three-stage unit, the WP100L, and since then, several hundred units have been installed on board various ships including cruise liners, ferries, oil tankers and cargo vessels.

Six three-stage, air-cooled compressors make up the range, all capable of operating at pressures of up to 45bar, with capacities ranging between 60m³/h and 360m³/h.

There are many other advantages including:

• 2,000 hours maintenance intervals for the valves
• Two years warranty
• Designed and tested for 60°C ambient conditions
• No need for expensive synthetic oils
• Reduced weight and space compared to water-cooled compressors
• No installation of cooling water pipes and fittings

Water-cooled compressors

Similar to other marine compressor designers, Sauer offered a range of vertical, two-stage, water-cooled compressors. These units were designed in the 1950s and 1960s and were stressed to their maximum parameters, both in running speed and operating pressures, thus resulting in poor reliability and difficult maintenance.

In the 1990s, Sauer & Sohn, along with several other leading marine manufacturers of air compressors, introduced a highly modern range of water-cooled units suitable for handling fresh or seawater as cooling medium.

These compressors are designed with the cylinders positioned in a 90° V-configuration resulting in an almost perfect balance of the units. These compressors are distinguished by many advantages, including:

• Motor flange coupled to the compressor
• Four point mounting system doing away with the need for a bedplate
• Replaceable liners fitted to both stages
• Straight cooler tubes for easy cleaning
• Crankshaft with bearings fitted to both ends
• Pressure oil lubrication by gear, direct driven pump from the crankshaft

There are three compressors in the range providing capacities from 110m³/h to 430m³/h at pressures of up to 30bar.

Screw compressors

For general service and control air applications, Sauer & Sohn offers a highly modern range of air-cooled, silenced screw compressors operating at pressures of up to 13bar. This most comprehensive range of machines covers outputs of up to 1,100m³/h. In addition to air-cooled units, water-cooled units are also offered.

Navy compressors

In addition to compressors for application in merchant ships, Sauer & Sohn offers shock and vibration proof navy compressors such as the unique WP 5000 with 100% free inertial forces for the use in naval combat ships such as aircraft carriers, frigates and submarines.

Service

Service station and agents throughout the world guarantee the necessary after-sales support and spare parts supply.
