1. Refrigerant imitations
2. Compressor and replacement parts copies

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.

GEA Bock at the Busworld Kortrijk

GEA Bock at the Busworld Kortrijk

It is time again. From 21-26.10.2011, the Busworld, the biggest and most renowned specialized exhibition for the coach and bus sector in the world takes place in Kortrijk, Belgium.

This year, the biennial event presents the latest developments and technologies of the industry and attracts once again interested experts and visitors from around the world. On more than 50,000 m2 exhibition space, the Busworld covers the sectors coach and bus builders, bus accessories, public transportation and tourism.

Also GEA Bock presents established solutions and new developments in Kortrijk this year. Besides the vehicle compressors of the FK-series for classical Diesel engines, new technologies have moved into GEA Bock's focus. For example special compressors for the use in hybrid systems.

These electric powered compressors offer numerous advantages for mobile applications. The aluminum version is for example about 40% lighter than comparable standard compressors and contributes to the innovative lightweight construction of vehicles.

Also the GEA Bock classics, the valve plates in K- and N-design are presented at the trade fair. The K-valve plate was specifically developed for the high demands of a bus airconditioning system. With the N valve plate, GEA Bock offers a less expensive alternative for the K-design that can be used for bus air-conditioning as well as all other applications.

With this broad portfolio, GEA Bock is prepared for today’s and tomorrow’s demands of airconditioning systems and is able to present individual solutions and new developments at the Busworld.

The GEA Bock team is looking forward to your visit at booth 4-9 at the Busworld Kortrijk.
