Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Oil-Free Compressor Driven Forced Evaporation Crystallizer with a 1500L batch volume and IP65 protection rating. As a dedicated manufacturer since 2015, we have supplied advanced crystallization solutions to over 15 global markets, with annual export values exceeding US$10 million. This equipment is engineered to achieve zero liquid discharge (ZLD) efficiently, using an oil-free compressor to drive forced evaporation—reducing energy consumption and maintenance costs. Perfect for industries requiring high-purity salt recovery and wastewater volume reduction, our crystallizer ensures reliable performance even in harsh environments.
The core advantage of this crystallizer lies in its oil-free compressor design, which eliminates the risk of oil contamination in the product stream. Combined with forced evaporation technology, it achieves rapid concentration and crystallization of dissolved solids. The 1500L batch capacity is ideal for mid-scale operations, while the IP65 enclosure guarantees dust-tight and water-jet protection, making it suitable for outdoor or wash-down installations.

Product Features & Benefits
- Oil-Free Compressor – Eliminates lubricant contamination, ensuring product purity and reducing filter replacement costs. Ideal for food-grade and pharmaceutical applications.
- Forced Evaporation Technology – Achieves rapid concentration even with high-boiling-point solutions, significantly shortening batch cycle time.
- 1500L Batch Volume – Balances throughput and footprint, suitable for small to medium-scale industrial wastewater treatment or chemical recovery.
- IP65 Protection – Fully sealed against dust and low-pressure water jets, enabling reliable operation in wet, dusty, or outdoor environments.
- Energy Efficient – The oil-free compressor reduces power consumption by up to 15% compared to traditional oil-lubricated systems, based on field tests.
- Automated Control – PLC with touch screen allows easy parameter setting, real-time monitoring, and data logging for process optimization.
- Corrosion-Resistant Design – All wetted parts in stainless steel, with optional anti-corrosion coating for aggressive chemicals.
- Low Maintenance – Fewer moving parts and no oil changes required, minimizing downtime and operational costs.

Frequently Asked Questions
-
Q: What is the difference between oil-free and oil-lubricated compressors in crystallization?
A: Oil-free compressors eliminate the risk of oil carryover into the product, which is critical for applications requiring high purity (e.g., food, pharma). They also reduce maintenance and filter replacement costs. -
Q: Can this crystallizer handle high-viscosity solutions?
A: Yes, the forced evaporation design maintains agitation and heat transfer even with viscous slurries. However, we recommend a pilot test for extremely high-viscosity feeds. -
Q: What is the typical batch cycle time for 1500L?
A: Cycle time depends on feed concentration and target solid content. Typically, it ranges from 4 to 12 hours. Our PLC system can optimize the cycle based on real-time sensors. -
Q: Is the IP65 rating sufficient for outdoor installation?
A: Yes, IP65 protects against dust ingress and low-pressure water jets, making it suitable for outdoor use. For extreme weather, additional weatherproof enclosures are available. -
Q: What certifications does your company hold?
A: Our factory is ISO9001, ISO14001, and OHSAS18001 certified. We also comply with other standards upon request (e.g., ASME for pressure vessels). -
Q: Can you customize the material of construction?
A: Absolutely. We offer SS304, SS316L, and higher-grade alloys like Duplex or Hastelloy for corrosive environments. Please specify your requirements. -
Q: What is the warranty period?
A: Standard warranty is 12 months from installation or 18 months from shipment, whichever comes first. Extended warranties are negotiable. -
Q: How do you ensure product quality before shipment?
A: Each unit undergoes a factory acceptance test (FAT) including pressure test, performance test, and electrical safety check. We provide a detailed test report.
