Our main area of expertise is "screw machines", which here means positive displacement machines with cylindrical, helically grooved rotors. Among these machines we find the common screw compressor and the screw expander, as well as low-pressure machines and pumps of different kinds. We are also working with related machines, like straight-lobe blowers and gears of special kinds.

Over 30 years of advanced work at the cutting edge of screw machine technology - including conception, design, testing and basic research, as well as development to a marketable product - has given us considerable experience in the following fields:

• Screw Rotor Profiles, tailored for a large variety of screw machines
• Rotor Manufacture and Quality Control
• Dry Screw Compressors for air and other gases
• Wet Screw Compressors for air (flooded with different fluids)
• Refrigeration and Air Conditioning Compressors, open and semi-hermetic
• Screw Expanders, working with steam or other gases
• Screw Pumps of various kinds
• Roots-type Blowers
• Superchargers
• Supercharging Systems
• Specific Designs for Capacity Control and Built-in Volume Ratio Variation
• Specific Designs of Bearings and Seals

• Design of "state-of-the-art" rotor profiles for any type of screw machine
• Development of all data necessary for the manufacture and quality control of screw rotors
• Recommendations regarding rotor geometry and porting
• Conceptual layouts
• Detailed layouts, suitable as a base for the development of all detail drawings necessary for manufacture
• General assistance regarding design, testing and evaluation of compressors and expanders
• Feasibility studies
• Troubleshooting
• Sale of Computer Programs for Screw Rotor Design, Manufacture and Quality Control
