LT-S-(L) Technical manual

Overview
For conventional single-stage screw compressors, Its evaporation temperature
can only reach -40~-50°C during freezing application. If you want to break this
application limitation, it is required to use two-stage compressor or cascade system.
Meanwhile, the working condition of high pressure ratio brings problems to the
traditional single-stage compressors during compression process, such as excessive
gas leakage and high exhaust temperature etc., which leads to low efficiency and poor
reliability when it is working is such harsh conditions.
The compound two-stage compressor well solves above problems. Compared
with the two-stage compressors or cascade system, the compund two-stage
compressors occupy less space and the system is easy to control, so it's more
efficiency and reliable.
LT Series compound two-stage compressor’s
evaporation temperature can be as
low as -60~-65°C , Its full load evaporating temperature can be -25°C, LT-S-L Series
compound two-stage low temperature compressor is based on the LT-S series which
modified the internal structure and optimized the motor matching to increase the
compressor full-load evaporation temperature to -10 ° C, So that LT-S-L series can
meet the requirements of industrial refrigeration
、
quick freezing tunnel and freezing
library without pre-cooling
For above reasons, Therefore The Shanghai Hanbell Precise Machinery Co., Ltd.
developed the LT series high temperature compressors. High efficiency and reliability
under big pressure differential and compression ratio working condition is the main
demand in designing. It is a elitist product which accumulates Shanghai Hanbell's rich
technology and extensive application experience. It can be widely used in many
industries such as high temperature hot water, central heating and so on.
