As a leading manufacturer from Qingdao Conqinphi Environmental Technology Group Co., Ltd., we proudly present our Specialized Sodium Nitrate Evaporator-Cooler, engineered for the demanding processes of fertilizer and dye manufacturing. With over 9 years of industry experience, our factory spanning 10,000–30,000 m² delivers precision equipment that optimizes sodium nitrate crystallization and cooling. This evaporator-cooler combines advanced heat exchange technology with robust construction, ensuring consistent product quality, energy efficiency, and minimal maintenance. Trusted by clients across North America, Europe, and Asia, our solution is designed to meet your production targets while reducing operational costs.
The Sodium Nitrate Evaporator-Cooler is a critical unit in the production of sodium nitrate, widely used as a nitrogen fertilizer and a key intermediate in dye synthesis. It efficiently concentrates sodium nitrate solutions through evaporation, followed by controlled cooling to induce crystallization. This integrated system eliminates the need for separate equipment, saving floor space and reducing energy consumption. Below we detail the core features, technical specifications, and benefits that make this equipment a valuable asset for your facility.
Key Features & Technical Advantages
- High-Efficiency Evaporation: Utilizes forced circulation or falling film design to achieve rapid concentration with minimal thermal degradation.
- Precision Cooling System: Jacketed or internal coil cooling with accurate temperature control (–5°C to 120°C) for optimal crystal size and purity.
- Corrosion-Resistant Materials: Constructed from SUS304 or SUS316L stainless steel, ensuring long service life even with aggressive sodium nitrate solutions.
- Flexible Capacity: Available in standard models from 1 to 20 tons/batch, with custom designs up to 50 tons/batch upon request.
- PLC Automation: Optional fully automated control system with touchscreen interface for monitoring temperature, pressure, and flow rate.
- Energy-Saving Design: Integrated heat recovery options (e.g., MVR or mechanical vapor recompression) can reduce energy consumption by up to 30%.
- Easy Maintenance: Quick-opening covers, CIP (clean-in-place) nozzles, and accessible components reduce downtime.

Frequently Asked Questions (FAQ)
Q1: What materials are used for the evaporator-cooler to handle sodium nitrate corrosion?
A: Standard construction is SUS304 stainless steel. For higher corrosion resistance, we recommend SUS316L or even titanium. Contact us for your specific solution composition.
Q2: Can this equipment handle varying feed concentrations?
A: Yes, the system is designed with a wide operating range. The PLC control can adjust heating and cooling parameters automatically to maintain stable output, even with fluctuating feed composition.
Q3: How does the cooling system work? Is it water-cooled or air-cooled?
A: Standard cooling is via a closed-loop chilled water system (water-cooled). Air-cooled condensers are available as an option for locations with limited water supply.
Q4: What is the typical lead time for manufacturing?
A: For standard models, lead time is 30–45 days. Customized units may require 60–90 days depending on complexity. We offer expedited delivery for urgent orders.
Q5: Do you provide installation and commissioning support?
A: Yes, we offer on-site installation supervision and commissioning services by our experienced engineers. Remote technical support is also available 24/7.
Q6: What certifications does this equipment meet?
A: Our manufacturing facilities are certified under ISO9001, ISO14000, OHSAS18001, and many others. Individual equipment can be designed to meet ASME, PED, or CE standards upon request.
Q7: Can the system be integrated with existing evaporation or drying lines?
A: Absolutely. We design modular systems that can be seamlessly integrated. Our engineering team will work with your plant layout to ensure compatibility.
Q8: What is the warranty period?
A: We offer a standard 12-month warranty from the date of commissioning, covering manufacturing defects. Extended warranty options are available.
