Continuous Crystallization Perfected

Crystallizing requires precise temperature and timing to efficiently produce consistent product. In bench top or batch applications, crystallization is tough enough. But crystallization gets even more complex when continuous operations are required. That’s where Bepex proprietary technology and industry-leading expertise come in – increasing throughput, providing on-spec product, and reducing operating costs.

Why choose Bepex?

We’re the material transformation people. And crystallization is an amazing – and highly demanding – material transformation process. Crystallization requires precise temperature control. Exact timing. Strict quality standards. And when the application switches from a batch to continuous processing approach, these processes become even more demanding. Bepex’s proprietary technologies make continuous crystallization possible – and profitable. That’s why Bepex is many engineers’ first call and final choice when they need a reliable crystallization process.

Efficient, Single Unit Operation

The Bepex Solidaire,  our leading crystallization technology, heats and evaporates solvent, then cools the heated liquid to form crystals, all in a single, low-footprint unit.

Focus on Throughput and Quality

We typically employ mechanical agitation in crystallization technology, which produces a more uniform, lump-free crystal size. This reduces crystallization time, while improving crystal quality.

Design Help from Crystallization Experts

Our process engineers are experts on continuous crystallization. They’ll work with you to design, test, quantify, and finetune your crystallization process. With a full library of proprietary and auxiliary components, we can simulate an entire continuous process system at the pilot-scale, proving feasibility and generating the information you need to scale your crystallization system to commercial capacities.

Process Development

Step 01


All new inquiries begin with a feasibility study. These studies aim to provide preliminary insights into the viability of a commercial process. Using as little as 100 grams of material, we can begin early process design, develop plans for pilot-testing and/or confirmation, and begin providing early economic estimates. Our experience across our wide range of technologies gives us a unique ability to provide quick feedback on the feasibility of your process.

Step 02


From our learnings, we’ll begin the process development work. The primary work in this phase takes place in the form of pilot-scale testing in our Process Development Center. Our pilot tests look a bit different than what you may have experienced in the past. Each test is designed to measure the system performance and feasibility rather than that of any single machine.

Each system is custom assembled for each test. Our goal is to provide as much of a pilot-scale simulation as possible while gathering scale-up data to deliver on commercial capacities. When a certain technology proves ineffective, we’ll draw from our range of options to determine if there is a better fit. The Process Development Center is our sandbox to build, test, and revise to ensure we get every detail right.

Step 03

Budget Evaluation

With a successful pilot simulation completed, we now have everything we need to scale up and provide proposals for capital equipment with included performance guarantees.

Step 04

System Design And Build

After receipt of the purchase order, we begin with both equipment and system engineering. Each proprietary technology we sell is custom-designed and built per application. We do not have any off-the-shelf units. At this stage, your exact system begins to take shape, including auxiliary equipment, process flow diagrams, process and instrumentation diagrams, safety provisions, and more.

Step 05


After delivery and installation of your new system, Bepex will provide a mechanical check to ensure everything is placed according to plan. This is followed shortly thereafter by system commissioning. This is where our pilot-scale simulations become invaluable, as our team of application engineers, controls technicians, and sales engineers begin working with your team to successfully bring your system online.

Step 06


At this point, you’re up and running at rate, producing a quality product, but our work doesn’t stop there. 

Following commissioning, Bepex remains a reliable partner, providing quality OEM parts, immediate field service, process optimization, training, system troubleshooting, and more. We have consistently had high customer retention rates, and we believe it is due in large part to our comprehensive approach to serving our customers long after the original sale.
