Product Overview
Product Model: LG16M12M—LG40M32M series
Compression Working Fluid: R717, R507, etc.
Nominal Working Condition: +40/-40℃
Nominal Cooling Capacity: 117KW-1450KW (R717), 157KW-2142KW (R507).
Features
lt is suitable for low temperature refrigeration under evaporating temperature below-25°ºCC, and the efficiency is significantly higher than that of single-stage compressor unit with economizer.
The mixing ratio is diverse. The optimum ratio can be selected according to different working conditions and medium of users The ratio of high and low pressure of R717 is between 3 and 4 and that of R507A is between 2 and 3.
The high and low pressure stages are equipped with energy adjustment devices to ensure that the unit is always efficient and economical under low temperature conditions.
The compressor of high and low pressure stages starts in different stages with low starting current.
The oil supply mode of low pressure stage compressor is pressure difference.
The high-pressure stage can be operated independently to achieve rapid cooling and high efficiency.
The unit is applicable to R717, R507A, R404A and other working medium.
The unit can be configured as required by users.
The control mode is automatic.
