Wordbock -
The online dictionary for refrigeration industry

There are numerous tools for translation online, but especially when it comes to technical terms, you face a ton of suggestions without knowing what to choose. The long and tiring search for the correct term often leads to mistakes or an inconsistent translation. Luckily, there is Wordbock to help – the first online tool that translates all technical terms of the refrigeration and air-conditioning industry.

With this dictionary for experts of the field refrigeration and air-conditioning, the correct translation in the languages German, English, French, Spanish and Russian is available with just one click.

The database that will continuously be expanded has currently more than 600 words per language and contains all important words around the compressor and refrigeration related terms and is therefore a helpful tool for the daily work in the industry. The preparation of a presentation or a lecture, the translation of a research paper or the own vocabulary training is thereby not only made easier, but also much quicker.

And if the right term is not available, the quick selection helps to find similar words that lead to an answer.

1. Attention! Dangerous R134a refrigerant imitations in circulation!

An increasing number of compressor breakdowns have occurred recently due to refrigerant imitations. Investigations of these fakes show that the imitation refrigerants, in this case declared as R134a, consisted mainly of R22, R30, R40 and R142b.

The Montreal Protocol has prohibited the use of R22 in new systems since 1 January 2010 and will forbid the general use of this refrigerant starting in 2015. The Halon Prohibition Ordi nance also prohibits the use and sale of R142b.

Chlormethane (R40) was used as a refrigerant before CFC refrigerants were developed. Accidents resulting from the reaction of R40 with aluminium are described in the literature. This reaction is said to create highly inflammable gases which are self-igniting and explosive on contact with air. After sufficient time, the aluminium is completely dissolved by the refrigerant. The oil does not hinder this severe attack. The aluminium compressors used in mobile refrigerating plants are attacked by chlormethane. In addition, plastic materials react with R40. Refrigerant tubes can be strongly damaged by this refrigerant.

The POE refrigerating-machine oil is strongly emulsified by the reaction with R40 and split into its component materials. Acids and alcohols result.

Also in circulation is diluted R134a, which contains R22 and, at times, propane. This creates the following problems in „hot countries“:

1.1 The temperature/pressure characteristics curves no longer agree. The addition of R22 reduces the pressure by about 1-1.5 bar compared to pure R134a. That means, when the system is at standstill, the correct refrigerant fill amount cannot be specified. Likewise, the apparent suction gas superheating of 7K is not real, but the compressor runs completely liquid.

1.2 Due to the addition of R22, the oil is no longer transported from the system back to the compressor. Some compressors will then break down due to a lack of lubrication.

1.3 The addition of propane increases the fire risk. Fires may result if the refrigerant is not suctioned away properly.

Bock becomes GEA Bock
New stickers with GEA logo

Since 1 April 2011 Bock is part of GEA Refrigeration Technologies. GEA Refrigeration Technologies is international market leader for industrial refrigeration systems and part of the GEA Group AG.

In the course of the integration of Bock into the GEA Group, Bock Kältemaschinen GmbH was changed into GEA Bock GmbH.

For this reason, the stickers on our spare parts, accessories and kits will be changed as well.

Launch in the series: Summer/Fall 2011

The benchmark of mobile air-conditioning – GEA Bock at the Busworld 2011

The benchmark of mobile air-conditioning – GEA Bock at the Busworld 2011

When Busworld 2011 in Kortrijk closed its gates on 26 October, one of GEA Bock’s most successful exhibitions of the last years ended.

The number of vehicles with Bock compressors displayed at the Busworld demonstrated impressively the claim of GEA Bock to be market leader of modern bus air-conditioning systems. Marcus Reuß, GEA Bock Director Sales and responsible for mobile applications drew a positive balance at the end of the exhibition: “We are very pleased to see that two-thirds of all buses exhibited at the Busworld use compressors by GEA Bock. This fact is exemplary for the success of the past years. At the same time we look into the future with optimism. Not least because we already work together with the leading system manufacturers on tomorrow’s air-conditioning systems.“

For example the Aluminum compressor HG34 in lightweight construction with integrated electric drive, presented at the Busworld. A compressor for highly efficient systems, especially developed for mobile applications, such as hybrid or trolley.

In addition, the company presented with its compressors of the FK series open-type compressors for a conventional drive via Diesel engine of the vehicle at its booth in hall 4.

GEA Bock presented itself for the first time as part of the GEA Group. The company that was family-owned until recently is part of the segment Refrigeration Technologies of the GEA Group AG since May this year. The GEA Group is an international system provider for food and energy processes with more than 20.000 employees and a revenue of EUR 4.4 billion.
