As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd. (established 2015), we proudly introduce our Air-Cooled Freeze Crystallization System — a robust solution designed for efficient separation and purification in demanding industrial environments. Crafted from premium Stainless Steel 316L, this system offers exceptional corrosion resistance and longevity, while its air-cooled design eliminates the need for complex water cooling infrastructure. With a precise temperature control range from -20°C to -80°C and standard 3 Phase 400V power supply, it is ideal for applications in chemical, pharmaceutical, and wastewater treatment sectors where reliable low-temperature crystallization is critical.
Our freeze crystallization technology leverages controlled freezing to separate dissolved solids from liquids, achieving high purity and minimal energy consumption. The system's 316L stainless steel construction ensures compatibility with corrosive media and harsh chemicals, while the air-cooled condenser simplifies installation and maintenance. The wide temperature range allows precise control over crystal size and morphology, enhancing product quality and process efficiency.
Key Features & Benefits
- Premium Material: Stainless Steel 316L provides superior resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, extending equipment lifespan.
- Air-Cooled Design: Eliminates need for cooling towers or chilled water systems, reducing auxiliary equipment costs and water consumption.
- Broad Temperature Range: From -20°C to -80°C enables processing of a wide variety of solutions with different freezing points, including brine, organic solvents, and waste streams.

Frequently Asked Questions
- What is the cooling capacity of this system? — Cooling capacity depends on the size and configuration. Standard units range from 5 kW to 50 kW at -40°C. Contact us with your required throughput for a custom specification.
- Can I use this system for corrosive liquids like acids? — Yes, the 316L stainless steel construction is resistant to many acids, chlorides, and harsh chemicals. For specific compatibility, please provide your process fluid details.
- How does the air-cooled condenser perform in high ambient temperatures? — Our system is designed to operate effectively up to 45°C ambient. For hotter climates, optional upgrades (e.g., oversized condenser or additional fans) are available.
- What is the typical delivery time? — Lead time varies from 30 to 60 days depending on customization and order volume. Standard models can be shipped faster.
- Do you provide installation support and training? — Yes, we offer on-site commissioning and training services for operators. Remote support is also available via video call.
- Is the system energy-efficient? — The air-cooled design eliminates water cooling energy, and the variable speed compressor (optional) can significantly reduce power consumption under partial load.
- Can the temperature range be extended beyond -80°C? — For lower temperatures (down to -100°C), a different refrigerant cascade system can be designed. Please inquire for ultra-low temperature requirements.
- What certifications does this equipment meet? — Our systems are manufactured under ISO9001 quality management system. Specific regional certifications (CE, ASME, etc.) can be arranged at extra cost, subject to your local regulations.
