Photoreactors – lab, pilot and industrial scale

Peschl Inc. is a subsidiary of the German Peschl Ultraviolet GmbH and specialized in manufacturing state-of-the-art photoreactors that meet the highest quality standards. In addition to commercial scale photoreactors we offer a wide range of application-optimized standard photoreactors as well as special light sources as a modular system to support fundamental, but also process related experiments in the lab.

As the market leader in applied photochemistry, we have been supplying efficient photoreactors for large-scale production worldwide for over 38 years. Our science-based consulting services and automated process development systems enable successful up-scaling in a short time.

STEP 1 - Photochemical screening

The PX 9 Parallel Screening Photoreactor is a new generation of modular wavelength screening instruments and the smallest batch photoreactor in the series. The unique feature of the photoreactor is its ability to perform nine irradiation tests in parallel with very small sample quantities and different wavelengths in parallel.

STEP 2 - Feasibility studies & process development

From batch to semi-batch to conti-flow photoreactors, we supply the full range of applications-based photoreactors specifically for fundamental experiments and feasibility studies on a laboratory scale as standard . These include falling film, tubular, side-loop and micro photoreactors. Depending on the application, you can choose between photoreactors with volumes from 2 ml to 5 l.

STEP 3 - pilot phase & commercial scale-up

Photoreactors and immersion lamp systems for photochemical production processes have been developed by our engineers, in order to be able to use radiation sources with power consumption of 1 kW up to 60 kW LED or medium / high pressure lamps in rough industrial environments, with the associated demands on failure and operating safety, control and documentation. We have been supplying flameproof certified photoreactors since 2002.

A technology changing revolution

LED-Photoreactors

Peschl has developed a breakthrough LED technology with the same refractive index as the immersion tube. The design has been carefully conceived to create a homogeneous light pattern that avoids dark zones and hot spots. The LED photoreactors are available with an impressive power consumption of up to 5 kW power per lamp, equivalent to a 30 kW medium pressure lamp.

The wavelengths range from 365 nm to 625 nm and achieve efficiency rates of up to 60%. A wide range of robust and reliable industrial scale LED photoreactors is offered. In addition LED photoreactors are available as flameproof versions.
