Halen TFR 200

High-Absorption Photochemistry

Description

The HALEN TFR 200 is specifically developed for photoreactions involving species with high absorption coefficients. These processes exhibit low transmittance, as photons are absorbed almost instantly at the exposed surface.

With our HALEN TFR 200, we offer high-absorption photochemistry at commercial scale. The reactors are designed to optimize the irradiation of the process stream by generating a thin film that is precisely tailored to the absorption profile. This safeguards efficient irradiation of the entire process liquid as it flows through the film, maximizing photon utilization and reaction efficiency. 

Equipped with the proprietary high-power flat LED technology developed by Peschl Ultraviolet GmbH, these flameproof flow photoreactors are designed for commercial production. The photonic energy generated by the LEDs in combination with the small volume of the flow reactor requires detailed modeling to secure the safe operation. We cooperate with a specialized party for CFD (Computational Fluid Dynamics) simulations on all our plate-type flow reactors.

Our reactors are engineered with high-pressure rating and minimal pressure drop. For production, multiple photoreactors can be cascaded into turnkey flameproof plants.

With the HALEN TFR 200 reactors, photochemical reactions involving highly absorbing substrates can be successfully scaled to commercial production.
