INDIVIDUAL SOLUTIONS
ON THE GO AROUND THE WORLD. BUT ALWAYS ONE STEP AHEAD. BITZER is setting benchmarks in bus air conditioning with innovative technology: our lightweight, compact compressors feature low vibration and noise and ensure just the right temperature and thus the comfort of your passengers. Regardless of the altitude and outside temperature – for every type of bus and drive. Whether electric or hybrid bus, diesel or natural gas, our extensive range of services offers the right technology for any application, whilst our global service network provides local support.
INNOVATIVE OUR DEVELOPMENTS: UNIQUE. OUR DRIVE: PASSION. BITZER offers you individual solutions tailored to the unique requirements of your bus applications. With the know-how of more than 80 years, we develop future-oriented products which offer unrivalled reliability. One example is the intelligent SPEEDLITE scroll compressor series, with its integrated frequency inverter specially developed for mobile applications. This compact lightweight provides maximum flexibility, simplified operation and maintenance, and smart protection functions.
EFFICIENT COMPACT. LIGHT. POWERFUL. PRETTY TALENTED FOR A FLYWEIGHT. Maximum capacity with minimum weight: our compressors in the compact aluminium design boast reliability and a long service life. BITZER’s exceptionally low-maintenance compressors offer extraordinary full- and part-load efficiency. Thanks to the virtually stepless CRII mechanical capacity control, reciprocating compressors can also be individually adjusted to meet the required operating conditions.
READY TO GO WELL EQUIPPED FOR THE FUTURE: AS THE FUTURE WILL BE ELECTRIC. The world is changing its thinking and we’re doing our part. BITZER has responded to the growing trend of electric and hybrid drives with sophisticated products. Take for instance the forward-looking SPEEDLITE scroll compressor series, which has been developed for high-voltage applications, among other things, and has made us a pioneer and role model in the industry. Developed for electric buses, this all-rounder is lighter than comparable compressors and has a simplified system.
FORWARD-LOOKING OUR PRODUCTS: RELIABLE. OUR RESPONSIBILITY: SUSTAINABLE. We offer sustainable solutions with maximum energy efficiency, with an awareness of our responsibility towards people and nature. As a leading compressor specialist and driver of innovation, we offer products which meet the requirements of tomorrow today.
