Semi-hermetic compressor smallest model for bitzer and Hanbell is 30hp,
And comparing the cost efficiency, from 50hp water chiller can be used screw type compressor;
And there are manufacturers use many scroll compressors together for big models, but this increased the risk of leaking problem.
So our standard design from 50HP adopted screw type compressors.
Air cooled screw chiller: 40TON TO 1000TON
Water cooled screw chiller:30TON TO 2000TON
