New Solutions.

For People and Environment.

We live up to our claim to develop systems and technologies that noticeably assist people and the environment, for example by implementing new ideas instead of chemical products. This does not only lead to the creation of high-performance solutions for UV-C sterilization which protect both people and the most sensitive products, but also results in the development of pioneering technologies such as KitTech and PlasmaStream which ensure effective deodorization and elimination of grease from exhaust air in the kitchen.

PlasmaStream technology Efficient odour elimination without chemicals.

Today there are numerous technical fields of application for modern plasma technologies. They range from surface and environmental engineering to measuring and ventilation technology where they serve to clean and reduce the odours in exhaust air from kitchens.

This exhaust air that is produced when food is prepared does not only bother people in the direct vicinity, it also contaminates the environment and the pollutants it contains can harm human health. BÄRO has developed PlasmaStream technology to remedy these problems.

Plasma is created when so much energy is supplied to a gas that a critical number of electrons leave the atomic shells. The result is an ionised gas, i.e. a mix of atoms, molecules and ions, surrounded by free electrons. In addition to solid, liquid and gaseous, plasma is the fourth state of matter and in terms of technical usability it has the important property of electrical conductivity.  In addition, plasmas have high chemical reactivity due to the existence (formation) of high-energy electrons, ions and radicals.

PlasmaStream technology from BÄRO is based on a purely physical principle.
It works with four successive functional stages:

1.      Pre-separation
The pre-filter (HydroStopp) keeps back the largest air impurities in order to protect the following stages.

2.      Ventilation
The fan with long-lasting EC technology creates an optimum flow of air.

3.      Oxidation
The plasma stage triggers an oxidation and decomposition process which converts the odours contained in the gas.

4.      Final stage
The active charcoal absorbs and decomposes any compounds not yet oxidised in the process.

The result is reduced odours in the kitchen exhaust air that complies with the strict provisions of the German Federal Immission Control Act (BimSchG) and can also be used for heat recovery with heat exchangers on account of its cleanliness.

PlasmaStream technologies from BÄRO have been tested by an independent institute, they are sustainable and do not present a health risk.

UV-C disinfection Effective systems for air and surface disinfection.

As early as 200 B.C. it was known that sunlight disinfects drinking water. In 1878 British scientists Arthur Downes and Thomas P. Blunt discovered that microorganisms did not multiply in strong sunlight, especially with UV-C radiation at a wavelength between 250 nm and 270 nm.

Today, the germicidal effect of UV-C radiation is used worldwide for environmentally friendly disinfection of air, surfaces and water. BÄRO offers effective UV-C systems for all kinds of different applications in the food industry, processing trades, in medical institutions, office buildings or the restaurant and food service industry.

Ultra-violet radiation is electromagnetic radiation that is invisible to the human eye. Due to the energy density a distinction is made between long-wave UV-A radiation (400 nm - 315 nm), medium-wave UV-B radiation (315 nm - 280 nm) and short-wave UV-C radiation (> 280 nm).

The most powerful effect that destroys the genetic make-up in the nucleus of micro-organisms occurs at precisely 253.7 nm as this wavelength renders the microbes harmless. However, microorganisms have very different resistance levels to UV-C radiation, which means that it is essential to find the correct radiation dose for destroying the DNA of bacteria, viruses, moulds, yeasts or algae – an important aspect, particularly in view of new multi-resistant types.
