LED Photoreactors

Peschl Ultraviolet GmbH has developed an innovative LED technology in which the LEDs are immersed in a non-conductive, highly transparent, chemically inert thermal fluid called “trisco®UV”, which has the same refractive index as the glass immersion tube. This is a major advance for the industry, as the use of this new LED technology can reduce both up to 90 % CO2 as well as costs compared to a medium pressure gas discharge light source.

Peschl now offers a wide range of robust and reliable industrial scale LED photoreactors that have been proven in harsh industrial conditions.

Industrial scale LED photoreactors are available with a power consumption of up to 5 kW per LED lamp, which is equivalent to a 30 kW medium pressure lamp, and suitable for process temperature ranges from -20°C … +120°C. If required, these are also available as ATEX-certified versions. Available wavelengths range from 365 nm to 625 nm with efficiencies of up to 60%.
