Green Innovations in China

Bock at the China Refrigeration 2010 in Beijing

Since its establishment in 1987, the exhibition China Refrigeration has developed into one of the leading trade fairs in the field of refrigeration, air-conditioning and heating. In the “New China International Exhibition Center” in Beijing that has an exhibition space of 7000 m², visitors can get information on new products and technologies and attend lectures, conferences and discussions from 7.-9. April 2010.

To put the focus on the protection of the environment, the motto of this year's exhibition is to "Stay on the Cutting Edge of the Industry, Make Contribution to Low-carbon Emission". Bock is also going to exhibit at the China Refrigeration and will present new products and solutions concerning those main issues and other topics at its booth W1F70.

Awarded for the protection of the environment – the Bock EFC-System

With the EFC System, Bock offers a Plug&Play frequency converter solution for a continuous rotation speed control of the compressor. A system that has an energy saving potential of 25% and more and was awarded by German Environmental Minister Dr. Norbert Röttgen with an innovation price.

The EFC-System is the leading Plug&Play solution for a continuous capacity regulation of refrigeration compressors and successfully established on the market since 7 years.

A solution that Bock offers now for the complete series of semi-hermetical compressors, from 2 – 8 cylinder models.

Natural refrigerants are on the advance – CO2 and hydrocarbons

In many parts of Europe they are already standard for many applications and even worldwide they are met with an increasing interest – natural refrigerants.

Especially CO2 applications have gone through a rapid development and subcritical CO2 applications are meanwhile the state of the technology.

Besides CO2, also non-halogenated hydrocarbons such as butane (R600/R600a) or propane (R290) have gained in importance. Due to their flammability, larger applications were rarely built in the past because of the required safety measures. At the China Refrigeration, Bock presents now for the first time its semi-hermetic compressors that consider those safety measures and are especially modified for the use with those refrigerants.


Certified Safety – Bock compressors for explosive environments

In environments where an explosive atmosphere as a mixture of air, flammable gases, steams or exhalations is prevalent, special regulations have to be applied, such as the ATEXDirectives of the European Union.

Such atmospheres do not only occur in the chemical industry, mining or the petroleum industry. Also in large parts of the manufacturing industry so-called ATEX zones can be found.

As the only European manufacturer, Bock offers a broad program of special ATEX-variations with its semi-hermetic compressor series HG.



Successful in maritime applications

The market of maritime applications has gained in importance for Bock China in the last few years. Particularly due to a massive boom of Chinese dockyards. Also for this field of application Bock presents at the China Refrigeration the right compressor solutions, such as the open type compressors of the Bock F-series or the open type two-stage compressors FZ.
