High performance reactors and heat exchangers

Rectangular does the trick.


Our highly efficient Miprowa® (milli)reactors and heat exchangers are true powerhouses when in comes to demanding chemical reactions that require fast heat dissipation together with continuous static mixing capabilities.

You are looking for fast scale-up from the smallest laboratory amounts to production volumes? This becomes a reality with our Miprowa® technology.

What makes it special?


The secret of the Miprowa® lies in the combination of channels with rectangular cross-sections with static mixing inserts. This increases the area-to-volume ratio compared to a conventional tube bundle of similar size and in this way enhances the heat transfer between the service medium and process side. The mixing inserts contribute significantly to this effect while at the same time affording efficient and continuous mixing even for multi-phase reactions. Additionally, control of reaction temperature is more defined leading to significantly increased yields and selectivities.

Our Miprowa® technology sets the standard in simple and fast scale-up from the smallest scale to production level: This compact equipment can easily master an annual production of up to 20,000 tonnes per year. The Miprowa® provides our customers from the chemical industry with the key to smart production with short return of investment periods.

Our integrated scale-up concept guarantees rapid scaling up within comparable channel geometries. When moving from the pilot stage to production, an equaling-up is carried out: The throughput is increased to the desired production quantity by numbering up to the required number of channels in parallel channel bundles within one reactor.

The Miprowa® series includes:
