Turbo expansion refrigeration generator set and turbo supercharging expansion refrigeration unit
Structural features
It is very similar to the chlorine gas compressor, and their structure compositions are almost the same.
Performance characteristics
The refrigeration efficiency is high, and the adiabatic efficiency can be higher than 80%; the flow capacity adapts to a wide range; the cooling speed is high, the cooling depth is high, and the minimum temperature can be lower than minus 100 degrees; the performance is reliable, continuous operation for more than 8000 hours is possible, and the service life can be longer than 10 years. With DCS or PLC automatic control and remot control, on-site operator on duty is no longer necessary.

Product advantages
1、A three-phase asynchronous generator is used for power generation, and the rotationalspeed, frequency, and voltage are controlled by the grid;
2、The rotational speed of the supercharged expander is adjustable, which is controlled by the inlet condition of the expander and the inlet and outlet conditions of the compressor；
3、Low investment, high efficiency, and the payback period of investment is generally 1.5 to 2 years.
