LT series semi-hermetic two-stage frequency conversion screw refrigeration compressor

LT-S-V and LT-S-IVX two-stage frequency conversion series compressor developed by Hanbell has accumulated many years of experience in refrigeration market. LT-S-V means two-stage variable frequency compressor, and LT-S-IVX means fully configured two-stage variable frequency compressor with frequency converter. In addition to inheriting the characteristics of normal LT model such as full-loading high efficiency under high pressure ratio and large differential pressure, wide operating temperature range, the new series products also introduces frequency conversion technology to improve the partial-loading efficiency, so as to improve the comprehensive efficiency of the compressor and reduce the operating costs. Through the frequency conversion technology, the capacity regulation accuracy is greatly improved, and the output cooling capacity can be effectively controlled, so as to reduce the fluctuation of warehouse temperature, reduce the wasting consumption, and further enhance the comprehensive competitiveness of the product.

 

In summary, LT-S-V and LT-S-IVX are highly suitable for freezing market demand. They are suitable for low-temperature refrigerators, quick-frozen tunnels and quick freezing storehouses, as well as other low temperature applications.


Features
Model Specification

High efficiency and energy saving

Adopt frequency conversion technology; the comprehensive energy efficiency is increased by more than 20% compared with the fixed frequency

 

Precise temperature control

It can realize step-less adjustment, accurately control the required temperature, improve the quality of frozen products and reduce wasted consumption.

 

Quick frozen

Wide temperature range of full load operation with frequency rise technology, which can greatly improve the cooling speed.

 

Cooling capacity increase

The maximum capacity of single compressor can reach 300Hp, which maximum can meet the cooling requirement of 2.5 ton screw freezer

Smooth start-up and stop

Full frequency control, eliminate the impact of starting current and shorten the reverse time of shutdown
