Family business in the third generation

Enthusiastic about new technologies and with a strong business sense, Wilhelm Bandelin founded RADIOLUX GmbH in Berlin-Steglitz. In the following "years of the economic miracle", he started the series production of measuring instruments for determining the accuracy of mechanical watch movements and founded TICK-O-GRAF W. Bandelin K. G. for this purpose. With the help of technical progress, it becomes possible to manufacture high-performance ultrasonic baths for cleaning watches and jewellery. The successors of the founder Wilhelm Bandelin are committed daily to the success of the company with their interdisciplinary expertise in the fields of electrical engineering, process engineering and business administration. The company's great independence and short decision-making paths have thus already been preserved in the third generation.

Custom-fit equipment with ultrasound

In addition to the wide range of series products, we offer our customers the possibility of equipping individual designs with our high-performance ultrasound. The ultrasonic vibration systems can be firmly connected to almost any flat metal surface with a diameter of at least 50 mm. Depending on the desired performance and size of the individual ultrasonic system, a variety of ultrasonic vibration systems can be applied to your component.


Our quality - your brand

Are you interested in high-quality ultrasonic baths, but do not have your own manufacturing capabilities? The solution is an OEM or OBL product. Here, almost all ultrasonic baths in our range can be customised in appearance. Adaptations can be realised with individual front plates, type plates and customer-specific instructions for use. We already have close partnerships with renowned dealers from various sectors and other manufacturers who expand their own portfolios with ultrasonic baths with their own brand or company logo, taking advantage of BANDELIN's high level of experience and manufacturing expertise. Our team will be happy to support you in a personal consultation in addition to the selection of equipment that is right for you, also in the design of the OEM / OBL agreement.

Combined heat and power plant

In the winter months, we use our combined heat and power unit to generate electricity and heat to heat the company building and to heat water. The fuel, natural gas, is converted into electrical energy. We use the waste heat that inevitably results from this process in a highly efficient way in the building via a water circuit. With an electrical output of 50 kW, the CHP generates more than 17TP2T of the company's electricity needs and more than 50% of its heat needs over the course of the year. When outside temperatures are particularly low, our gas condensing boilers switch on automatically and ensure comfortable temperatures at all times.

LED conversion

To further reduce the electricity demand in the building, we have replaced the most electricity-consuming luminaires in production and administration with LED luminaires. With this measure, we can reduce the electricity demand of a lamp by more than 50 % with the same brightness. For the entire company, this means a reduction in electricity demand of more than 10 % over the entire year. In addition, we will further expand the use of motion detectors and daylight-dependent control of the lamps, which we have already implemented today, and save even more energy.

Photovoltaic system

The solar system on our company roof with a total output of 54 kW produces almost 20 % of the company's total electricity needs over the year. At the weekend, the surplus electricity is fed into the Berlin power grid, where it increases the share of renewable energies in the grid. The majority of the modules face south and generate the most power during the midday hours. About half of the modules face south-east and south-west, enabling efficient use of the sun in the morning and afternoon. This means that solar energy can be used for production over a wide range of the day.
