    Art guardians: Climate's silent protectors

    The Suermondt-Ludwig Museum in Aachen needed to maintain a constant indoor temperature of and a relative humidity. In addition, it had to be environmentally friendly, energy-efficient, and utilize a climate-friendly refrigerant. The solution was transcritical CO2 chillers, each equipped with two Bock compressors using CO2 as the refrigerant. This project successfully combines art preservation with eco-friendliness and energy efficiency.

    Hugo the compressor, our work horse

    Too fit to slow down. Still fit, with over 160,000 operating hours behind it: Hugo the compressor purrs like it did on the first day. Hugo is an HK2C type semi-hermetic compressor, built in 1955. It has one cylinder and runs at 1,450 revolutions per minute. It is named after Hugo Bock who, together with company founders Wilhelm Bock and Erich Etter, was managing the company when Hugo was built.
