UK:  BITZER has optimised its proven CR capacity control system by adding blocked suction and with the new CRII system, BITZER offers a whole new level of flexibility with the option to adjust the operation of ECOLINE compressors in line with operating conditions. 

Depending on these conditions and refrigerant, a special control algorithm allows compressors to be infinitely adjusted.  With the CRII, BITZER has achieved an exceptionally wide range of control between 10 and 100% for four and six-cylinder compressors.  The increased switching frequency ensures smaller fluctuations in controlled value, temperature and pressure. In combination with the expanded range of control, this optimises system efficiency.

Compressors are available with the CRII cylinder heads pre-installed.  The CRII system is also backwards compatible and available for retrofitting to the ECOLINE four to eight cylinders models including 4FES-3(Y) to 6FE-50(Y) as well as the two external cylinder banks in the 8GE-50(Y) to 8FE-70(Y) compressors.

The software has been updated to the latest Apple system IOS 7 and for Android tablets, the programming has been optimised to achieve a better presentation and simpler handling of the functions. 

Various languages

As well as German and English, now French, Russian, Spanish, Portuguese, Chinese, Japanese, Hindi and Indonesian languages are also available on the app.

Unique material recommendations

After numerous tests and laboratory analyses, Güntner have published recommendations for material combinations for components depending on the planned application. This unique information overview, much sought-after for years, is now an implemented app function. It lets you check the ambient conditions for a suitable unit design at any time.

Refrigerant slide

The app function "Slide" displays the pressure-temperature correlation for more than a dozen of the most commonly used refrigerants. These include refrigerants that are relevant today such as 245fa. Users enter a specific temperature as required and the refrigerant slide shows the corresponding gauge pressure in bar.

The refrigerant-specific ODP (Ozone Depletion Potential) and GWP (Global Warming Potential) values are also shown.

"Converter" for easy conversion

A total of 18 refrigerating variables such as pressure, temperature, volume and mass flow density, can be converted into every unit globally used and then displayed. As a result, users will always find a common basis for measurements – regardless of where in the world a construction site happens to be.

"Service Documents" – a complete collection of documents

The "Service Documents" function provides you with documents for all the Güntner lines of business and units. Documents are first sorted regionally. This is done automatically depending on the basic mobile phone or location settings. Users can then select the required documents according to the sorted languages and units. From info brochures to operating instructions, information is just a click away. This is particularly useful for service technicians and others who might want to take a glance at the unit’s operating instructions on site.

Contact information immediately available

The "Contacts" function offers an overview of all the Güntner field representatives. All stated contact data are active, meaning users can plan their route from their current location on the basis of the address, they can call/e-mail a contact directly, share information with others or add the details to their own list of contacts.

The contact information also includes details for the Service and Spare Parts departments. As a result, you will always reach the right contact person.

UK:  With such a large focus on high GWP refrigerants the big brand Air Conditioning manufacturers have all moved forward with the use of HFC-32, a viable lower GWP refrigerant replacement for R410A.

The technology has been available for just over 2 years now and companies such as Daikin, Panasonic, Fujitsu General, Hitachi and Toshiba are all now using HFC-32.

With more manufacturers releasing R32 systems and the inevitability of larger R32 systems hitting the market in the future, it is imperative that technicians are fully trained on the new tools and equipment needed to service this market as well as understanding the safety of what is still considered a flammable refrigerant.

Many service technicians may not be aware that specialist tools are needed to service R32 systems. R32 is mildly flammable and has higher operating pressures and not using R32 compliant equipment can compromise safety which could result in injury. 

While some technicians may not have yet started working on R32 air conditioning systems, it is highly likely they will in the future, so when buying new equipment, they should make sure it is R32 compliant as this will ensure safe work practice and save equipment upgrade costs in the future.

USA: With discussions very much focused on the phase out of R22 and the general state of the US refrigeration industry, which has now been charged with following in the footsteps of Europe and must completely eliminate the use of R22 by 2020, ATMOsphere was the perfect place for Azane Inc. a US manufacturer of industrial chillers and freezers, to showcase their low charge ammonia refrigeration technology to industry professionals and leading end-users. 

Ammonia is the natural refrigerant of choice used in all Azane products. It has a zero global warming potential and a zero ozone depleting potential. Ammonia is also highly efficient, with research showing energy savings of 20%+ when compared with HFC's.

Azane seems the best choice for the R22 replacement as its low charge systems use an equivalent of just 20% of the ammonia charge of a traditional ammonia refrigeration system, which makes them a particularly safer and energy efficient solution.


Engineering expert Derek Hamilton, a US Business Development Manager for Star Refrigeration, discussed the different options available for R22 replacement, including drop-in refrigerants, HFCs, blended and natural refrigerants such as low charge ammonia and CO2.

"Different alternatives are readily accessible, but only natural refrigerants ensure a regulatory free, environmentally friendly and long-term solution," said Hamilton.

"With a total duty of 190 TR, the Azane low charge system is designed to supply cooling water at 40°F using a high efficiency air cooled Azanechiller."

"Analysis of the Azanechiller showed that the energy bill will be reduced by over $40,000 a year, compared to an equivalent HFC air cooled chiller."

About Azane Inc: Azane is a subsidiary of leading European refrigeration contractor Star Refrigeration, renowned for its work in natural refrigeration technology since 1970 and numerous technical papers on CO2 and ammonia published through ASHRAE.
