Ultra-low Temperature Water-cooled Screw Cascade Chiller - For Cryogenic Process Cooling 30HP-500HP

The Ultra-low Temperature Water-cooled Screw Cascade Chiller is a specialized solution for cryogenic process cooling, engineered to deliver temperatures as low as -120°C with unparalleled stability. Its cascade system—featuring dual screw compressors working in tandem—ensures efficient heat transfer across extreme temperature ranges, making it indispensable for industries like aerospace materials testing, pharmaceutical freeze-drying, and specialty chemical processing.?
The water-cooled design enhances energy efficiency by 20% compared to air-cooled alternatives, with a robust condenser that excels in high-ambient environments. The screw compressors’ precision engineering minimizes vibration and noise, while their variable capacity control adapts seamlessly to fluctuating cooling loads—critical for batch or continuous cryogenic processes.?
Constructed with industrial-grade materials (stainless steel pipelines, low-temperature refrigerants), it resists corrosion and thermal stress. Equipped with a PLC control system, operators can monitor real-time parameters and set automated cooling profiles, with safety features (low-pressure alarms, overcurrent protection) preventing system failures. Certified to ATEX and ISO standards, this chiller guarantees reliability in the most demanding cryogenic process cooling applications.

Product details

Product Description:

Customizable options include acid resistance, corrosion prevention, frequency conversion, and explosion proof. The HY-WL series of water-cooled low-temperature chillers is a new generation of low-temperature refrigeration equipment meticulously designed and developed by Shenzhen Linghang Refrigeration for specific industries such as pharmaceuticals and chemicals. With a temperature range adjustable between -5°C and -95°C, these chillers utilize original compressors from Hanzhong, Bitzer, and Fusheng, offering a complete range of refrigeration circuits. They serve as a paradigm of the new generation of refrigeration equipment.

Product Features:

Product advantages:

The compressor uses imported famous brand semi enclosed screw compressors such as BITZER, HANBELL, REFCOMP, etc. The electrical equipment uses Schneider/LG, with a cooling capacity of 30kw-1500kw.The temperature can be customized according to the customer's process requirements (-5 'C to-90 °c), and can be double or triple stacked according to the temperature. lt has stable and reliable operation, high efficiency, low failure rate,and low vibration noise. The acid resistant, anti-corrosion, variable frequency, and explosion-proof units can be customized according to the customer's requirements.

Application areas:

The Dongxing series of products are widely used in industries such as new energy, lithium batteries, petroleum, chemical, hydrogen energy, electroplating, anodizing, fermentation, coating, grinding, medicine,plastics, electronics, aquaculture, food, laboratory, printing, laser, glass, ultrasonic cleaning,and supporting refrigeration systems.

Designed for cryogenic process cooling, the Ultra-low Temperature Water-cooled Screw Cascade Chiller combines advanced technology with rugged performance to handle extreme low-temperature demands. Its cascade configuration—utilizing two independent refrigerant circuits—enables precise temperature control from -50°C to -130°C, making it ideal for applications such as biological sample preservation, superconductive material testing, and low-temperature metallurgy.

The water-cooled condenser ensures optimal heat dissipation even in high-heat industrial settings, while the screw compressors deliver consistent power with minimal energy waste. This design reduces operational costs while maintaining the tight temperature tolerances (±1°C) required for sensitive cryogenic processes.

Built for durability, the chiller features insulated components to prevent condensation and thermal loss, along with a user-friendly HMI interface for easy parameter adjustment. It integrates seamlessly with existing process systems, with options for remote monitoring and data logging to meet compliance requirements. Backed by global technical support, this industrial-grade chiller is a trusted partner in maintaining the integrity of critical cryogenic processes.
