Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a leading manufacturer with over 9 years of expertise in environmental equipment. Our Compact Three-effect Forced Circulation Evaporation Crystallizer with explosion-proof design is engineered to deliver reliable, high-efficiency concentration and crystallization for demanding industrial processes. Built for safe operation in hazardous environments, this unit combines space-saving construction with robust performance, making it an ideal choice for wastewater reduction and chemical recovery.
At our 10,000-30,000 sqm factory, we integrate advanced manufacturing techniques to ensure every crystallizer meets strict quality standards. With annual exports exceeding US$10 million to markets across North America, Europe, and Asia, our products have proven their value in diverse applications. The unit's three-effect forced circulation design maximizes energy efficiency while minimizing footprint – a critical advantage for plants with space constraints.
Key Features & Technical Specifications
- Three-effect forced circulation: Achieves high concentration ratios (up to 30% solids) with reduced steam consumption compared to single-effect systems.
- Explosion-proof construction: All electrical components (motors, sensors, control panel) comply with international standards (e.g., ATEX/IECEx optional), ensuring safe operation in flammable environments.
- Compact modular design: Pre-assembled skid-mounted system reduces installation time and occupies minimal floor space (approx. 6m x 3m for a 1000 L/h model).
- 380V/60Hz power compatibility: Standard motor and heater ratings for North American and other 60Hz markets, with optional voltage/frequency customization.
- Robust material selection: Wetted parts available in 316L stainless steel or higher alloys (Hastelloy, Duplex) for corrosive or abrasive feeds.
- PLC-based automation: Touchscreen HMI for real-time monitoring of temperature, pressure, flow, and level; optional remote access via SCADA.

Frequently Asked Questions
-
Q: Can this crystallizer handle corrosive liquids like acidic wastewater?
A: Yes, the wetted parts can be constructed from Hastelloy, titanium, or other corrosion-resistant alloys upon request. Standard 316L SS is suitable for many chloride-containing streams. -
Q: What is the typical footprint for a 1000 L/h unit?
A: Approx. 6m (L) x 3m (W) x 4m (H), but dimensions vary with capacity. Our engineers provide a detailed layout during proposal. -
Q: Is the explosion-proof certification included by default?
A: The design follows explosion-proof principles, but specific certification (e.g., ATEX, IECEx, NEC) can be added as an option based on your region's requirements. -
Q: What after-sales support do you offer?
A: We provide installation guidance, commissioning, spare parts supply, and remote technical support. On-site service is available at an extra cost. -
Q: How long does delivery usually take?
A: Lead time is typically 30-60 days after order confirmation, depending on customization level and current production schedule. -
Q: Can the unit run on 50Hz power supply?
A: Yes, with a suitable transformer or VFD. Please specify your local power conditions during inquiry. -
Q: What maintenance is required?
A: Routine cleaning of heat exchange surfaces every 3-6 months, pump seal inspection, and lubrication of moving parts. We provide a detailed maintenance manual. -
Q: Do you have references in the chemical industry?
A: Absolutely. We have supplied similar units to multiple chemical plants in Europe and Asia. Reference lists are available upon request.
