24-hour high-frequency continuous operation and long lifespan
The food quick-freezing and refrigeration processing chain has zero tolerance for "cooling interruption".
• High reliability: Adopting a rotary twin-screw design, with very few moving parts and extremely low mechanical wear.
• Design lifespan: Designed for the 24/7 full-load high-frequency operation requirements of food factories, under regular maintenance, the operating lifespan of the main unit typically exceeds 100,000 hours, meeting the stable cooling source requirements for the long-term continuous production of food factories.
- Adopt the most advanced technical speed regulating electric motor-permanent magnetic motor, efficiency can be up to 97%, higher by 3%-4% than common frequency conversion device and motors type, saving energy obviously.
-
Permanent magnetic motor and the screw compression main devise adopt embedded integrated direct-connecting structure, without coupling part or transmission gear, ensure 100% transmission efficiency.

The whole machine work in frequency conversion state, and can operate frequency modulation according to the client's actual requirement of air consumption, realizing high efficiency and energy saving.

Machine starting on frequency conversion state, greatly reducing the impact to the power grid equipment, avoiding of damage to the electric equipment, and saving electric energy when starting.
- Permanent magnetic electric motor is without motor bearing or sleeve, so no need lubricating grease, no concern alignment problem, compact structure, convenient use and maintenance.
- No need to set working pressure up and bottom limit value, can operate by regulating the frequency at the setting pressure point to stabilize the pressure, so can save electric energy by 10%-15%.
- Compared with the fixed speed compressor, our compressor can save energy by 30%; compared with the common frequency compressor, our compressor can save energy by 5%-10%.

The load of food processing plants fluctuates significantly (for example, a peak cooling capacity is required during rapid freezing of ingredients, while a very low capacity is needed during insulation).
• Variable Volume Ratio (Volumizer): The compressor is equipped with a patented Vi variable volume ratio control and valve adjustment system, supporting stepless capacity adjustment from 10% to 100%.
• Energy-saving benefits: The compressor can perfectly match the real-time load changes of the food line, avoiding the power waste and mechanical shock caused by frequent start-stop of traditional compressors, and has a high overall energy efficiency.
Food-grade safe and environmentally friendly working medium
• Ammonia (NH₃) and carbon dioxide (CO₂) refrigeration system: The food industry (especially large breweries, dairy farms, and slaughterhouses) widely adopts environmentally friendly natural refrigerants. High-pressure twin-screw compressors are often used in CO₂/NH₃ cascade refrigeration systems or ammonia heat pump systems, which are both environmentally friendly and can provide extremely low freezing temperatures (down to -40℃ or below).
• Strict oil management and dedicated refrigeration oil: The system is equipped with an extremely efficient oil separator, combined with dedicated long-life synthetic refrigeration oil, to ensure that lubricating oil does not contaminate the food cooling or freezing areas at the front end.
