Below you will find a detailed breakdown of the crystallizer’s features, technical specifications, and the tangible benefits it brings to your process.
Key Product Features
- MVR Technology: Utilizes mechanical vapor recompression to recycle latent heat, reducing energy consumption by up to 60% compared to traditional evaporators.
- Compact Footprint: The entire system is designed to occupy minimal floor space – ideal for laboratories, pilot plants, or production lines with space constraints.
- Precise Temperature Control: Adjustable from 0°C to 60°C, allowing fine-tuning for optimal crystallization conditions of ammonium chloride and other heat-sensitive compounds.
- Stable 3kW Power Output: A dedicated compressor and heating system ensure consistent operation with low vibration and noise.
- High Efficiency Crystallization: Combines cooling crystallization with MVR to achieve high product purity and uniform crystal size distribution.
- Intelligent Automation: PLC-based control with touch-screen interface enables one‑click start, real‑time monitoring, and data logging.
- Corrosion Resistant Construction: Standard wetted parts are 316L stainless steel; other alloys (Hastelloy, titanium) are available upon request for aggressive media.
- Easy Maintenance: Modular design with quick‑access ports simplifies cleaning and inspection.

Frequently Asked Questions
Q1: Can this crystallizer handle ammonium chloride solutions with high impurity levels?
Yes, the 316L stainless steel construction resists corrosion from chloride ions, and the temperature control allows you to adjust cooling rate to selectively crystallize ammonium chloride while keeping impurities in solution. For extremely aggressive media, optional Hastelloy wetted parts are available.
Q2: What is the minimum operating temperature I can achieve?
The standard system can reach 0°C at the cooling jacket outlet. If you require lower temperatures (e.g., -5°C), an auxiliary chiller can be integrated — please consult our engineers for a custom solution.
Q3: How long does it take to see return on investment?
Typical ROI ranges from 12 to 24 months, depending on local electricity costs, operating hours, and the value of recovered product. Many clients report even faster payback when processing high‑value crystals.
Q4: Do you provide installation and commissioning support?
Yes, we offer on‑site commissioning by our experienced engineers. Remote guidance via video call is also available for basic startup. Detailed manuals and spare parts lists are provided.
Q5: Can the crystallizer be automated for 24/7 operation?
Absolutely. The PLC control system supports fully automatic operation with alarms, data logging, and remote monitoring via optional SCADA interface. The compact unit is designed for continuous duty.
Q6: What is the typical crystal size distribution?
Under recommended conditions, the mean crystal size is 100–300 microns with a narrow distribution. You can modify parameters (cooling rate, agitation speed) to shift the size range as needed.
Q7: Is the system easy to clean between batches?
Yes, the design includes CIP (clean‑in‑place) spray balls and drain valves. All product contact surfaces are polished to Ra ≤ 0.8 µm, minimizing residue buildup.
Q8: Can I use this crystallizer for other chemicals besides ammonium chloride?
It is suitable for many inorganic salts and some organic compounds that crystallize upon cooling. We recommend a small‑scale test with your specific solution to verify compatibility and optimize parameters. Custom materials can be provided for corrosive or high‑purity applications.
