Re: Single screw compressor
Working for manufacturers will allow you to learn a lot in a short time. They see every little problem you can think of with refrigeraiton systems.
Why?
Because everyone always blames the equipment for not working properly and they have to work with the customer to provide a solution.
If you do this for the learning experience it is OK. If you do this for the money you will be disappointed.
If all else fails, ask for help.

Re: Single screw compressor
Reality check here. The screws dont have much between them. seriously they are practically the same in every way. All it is with reliabilty is that the engineer who built the machine and the engineer who is looking after the machine. All manufacturers test their machines to destruction im sure. They know what they can do. Single screw is very reliable as long as the running conditions are correct. I have had one running a very long time 10yrs+ on -25 duty single stage and has never had a bearing change. Just the same as ive seen twin screws doing the same. Design and commissioning is important but not everything.

Re: Single screw compressor
I purchased 4 Vilter VSS mono screws, had many problems with capacity control gear motors, liguid injection control and pump problems. Slide valves would rub on the screw and gate rotors would wear out quickly. Also had to rebuild each one as least once in a five year period. I now have 4 Frick RWF-II twin screws and have had to rebuild only one in ten years.
