BITZER Highlights at the AHR Expo in Chicago http://www.r744.com/news/view/6043 http://www.r744.com/news/view/6043 2015-01-22 12:22:17 article <ul> <li>Wide range of applications: ORBIT 6 and 8 scroll compressors</li> <li>Can be flexibly combined: BITZER Advanced Header Technology</li> <li>With new drive: CSVW2 screw compressor</li> <li>Successful around the world: ECOLINE reciprocating compressor</li> <li>High-pressure innovation: CO<sub>2</sub> compressors</li> </ul> <br /> Right at the start of 2015, BITZER is presenting its latest products at the AHR Expo trade fair in Chicago (Illinois, USA). On the compressor specialist&rsquo;s stand (in South Hall, stand 5036) visitors to the international trade fair can get information about their full product range of scroll, screw and reciprocating compressors.<br /> <br /> BITZER&rsquo;s highlights at AHR Expo 2015 include the ORBIT 6 and 8 scroll compressors, with their high isentropic efficiency and their excellent energy efficiency. The five models in the ORBIT 6 series offer a delivery rate of between 20 and 38 m<sup>3</sup>/h (50 Hz), and really impress with their wide range of applications as well as with their low noise levels. With a cooling capacity of between 27 and 51 kW at 50 Hz, they are especially suitable for air conditioning systems and heat pumps. Just like the ORBIT 6 scroll compressors, the ORBIT 8 series has been designed for the R410A refrigerant. The six ORBIT 8 compressors have a delivery rate of between 29 and 77 m3/h (50 Hz), achieve high efficiency rates and their operating noise levels are up to 3 dB(A) lower than comparable compressors.<br /> <br /> <b>Can Be Flexibly Combined</b><br /> <br /> Thanks to BITZER Advanced Header Technology, it is now possible to operate differing scroll compressors in parallel &ndash; without using any active oil management. This enables BITZER to offer up to 20 different combinations, with different performance, using ORBIT scroll compressors. For example, users can thus combine ORBIT 6 and 8 compressors in a single system.<br /> <br /> <b>A New Drive</b><br /> <br /> The CSVW2 compact screw compressors are an innovation with their integrated frequency inverters. BITZER has developed the compressors for use in water cooled chillers for systems with low saturation discharge temperatures and which are equipped with new permanent magnet motors. These motors are very efficient and, in particular, are more efficient than conventional motor technologies at lower speeds and loading ranges. Thanks to their innovative drive technology, the CSVW2 compact screw compressors have a high energy efficiency rating (EER) and a good ESEER value.<br /> <br /> <b>The Right Screw for Every Application</b><br /> <br /> BITZER is also showing its CSH series at the AHR Expo. Thanks to their optimized oil management, the semi-hermetic compact screw compressors are especially efficient when partially loaded and are very well suited to applications with higher saturation discharge temperatures. They have been designed for use in air conditioning systems, heat pumps and in individual, short circuits. With its OS series, BITZER is also presenting trade fair visitors with an open screw compressor, which was designed for the natural and carbon-neutral refrigerant ammonia (R717). This series&rsquo; special characteristics include its high system performance, its optimal power adjustment and its efficient use of energy when fully or partially loaded as well as its economizer mode.<br /> <br /> <b>Successful around the World: ECOLINE Reciprocating Compressor</b><br /> <br /> The semi-hermetic ECOLINE reciprocating compressors are another highlight which BITZER successfully produces and distributes worldwide. The company has improved the cooling coefficient of performance (COP) of the entire series by up to 12 percent and has designed them to be flexible for the refrigerants R134a, R404A, R407A, R407C, R407F, R507A, R290 and R1270. With the new CRII capacity control, the ECOLINE reciprocating compressor&rsquo;s range of control can be flexibly set between 10 and 100 percent. This lowers operating costs while protecting the environment. In the VARISPEED version, thanks to the frequency inverter being cooled by the suction gas, the ECOLINE reciprocating compressors have very good efficiency values. The smooth speed control minimizes the frequency of switching, thus lowering the energy costs. The suction gas cooling also ensures that the electrical parts operate at their optimum temperature.<br /> <br /> <b>High-Pressure Innovation: CO<sub>2</sub> Compressor</b><br /> <br /> BITZER is also showing its semi-hermetic CO<sub>2</sub> reciprocating compressor from the OCTAGON series for sub-critical and trans-critical cycle applications. The delivery volumes of the sub-critical cycle OCTAGON series is between 1.33 m<sup>3</sup>/h and 46.9 m<sup>3</sup>/h, and for the trans-critical cycle series, it is between 3.3 m<sup>3</sup>/h and 37.9 m<sup>3</sup>/h. BITZER has more than 15 years of experience in the manufacture of CO<sub>2</sub> compressors and is one the established providers of environmentally friendly technology in the USA.<br /> <br /> <br type="_moz" /> <br /> Sainsbury's powers fridges using its suppliers' sugar beet waste http://www.r744.com/news/view/6042 http://www.r744.com/news/view/6042 2015-01-22 10:45:00 article Sainsbury&rsquo;s has pioneered new technology to power its fridges in its Portishead store with the new CO<sub>2</sub> natural refrigerant from A-Gas - eCO<sub>2</sub> - that&rsquo;s produced entirely from waste.<br /><br />eCO<sub>2</sub> is the first high specification Carbon Dioxide refrigerant to be produced sustainably in the UK and is a product that can make a significant difference in cutting a store&rsquo;s carbon footprint.&nbsp;<br /><br />Sainsbury&rsquo;s is looking to reduce operational Carbon emissions by 30% absolute and 65% relative compared to 2005; and at Portishead the supermarket group believes eCO<sub>2</sub> is a refrigerant which can make an important contribution to this.<br /><br /><br /> Why Target opted for CO2 as its prototype http://www.r744.com/news/view/6033 http://www.r744.com/news/view/6033 2015-01-20 17:13:00 article A CO<sub>2</sub> cascade refrigeration system met engineering chief Paul Anderson&rsquo;s efficiency requirements, but victory on total costs remains down the road.At ATMOsphere America 2014, Paul Anderson, Target&rsquo;s Engineering Chiefannounced that retail giant would shift to CO<sub>2</sub> hybrid systems for new stores and major remodels.In the cover story of issue 3 of Accelerate America, Paul Anderson provides an exclusive insight intowhy Target has committed to CO<sub>2</sub>.

Bitzer's New International Training Center http://www.r744.com/news/view/6013 http://www.r744.com/news/view/6013 2015-01-15 09:55:19 article <div><i>Specialist in refrigeration compressors BITZER has been building an international training center in Rottenburg-Ergenzingen (Germany) since August 2014: the SCHAUFLER Academy.</i></div> <br type="_moz" /> <ul> <li>Completion scheduled for October 2015</li> <li>Innovative Energy Concept</li> <li>A diverse training program focusing on refrigeration compressors, components and system solutions</li> </ul> <br /> Sindelfingen/Rottenburg, January 14, 2015. Construction of the SCHAUFLER Academy, the international training center at the Rottenburg-Ergenzingen location, kicked off in August 2014. Measuring 1,500 square meters, the innovative facility is scheduled for completion in October 2015. BITZER is therefore further pursuing its strategy to expand the Rottenburg-Ergenzingen location, now in construction phase 8.<br /> <br /> &ldquo;With the construction of the SCHAUFLER Academy in Rottenburg, BITZER is clearly demonstrating its intention to continue investing in this region in the future,&rdquo; explains J&uuml;rgen Kleiner, Chief Procurement Officer at BITZER. Named after BITZER CEO Peter Schaufler, Peter-Schaufler-Strasse leads to the current large-scale project &ndash; the SCHAUFLER Academy &ndash; and will be the new address of the Rottenburg-Ergenzingen location following completion of construction. Because the SCHAUFLER Academy was designed to be a multifunctional building, it will also be the new main entrance and representative reception building for the entire factory, providing the location with a unique ambience.<br /> <br /> &quot;We decided to build the SCHAUFLER Academy for many different reasons,&rdquo; says Rainer Gro&szlig;e-Kracht, Chief Technology Officer at BITZER. &ldquo;The complexity of BITZER compressors and products is always increasing, for example due to the integrated frequency inverters, electronic components and new CO2 systems. Technically demanding solutions also require a well-trained service staff. The SCHAUFLER Academy will be the central training location for customers and employees from all over the world. Here we&rsquo;ll offer the training courses that keep the maintenance teams of our business partners up to date.&rdquo;<br /> <br /> <b>Multifunctional</b><br /> <br /> A major advantage of the three-story, ten-meter-tall SCHAUFLER academy is that it can host several training courses at the same time as it offers five rooms for teaching the necessary theory and three for practical training. BITZER planned the SCHAUFLER academy to be a multifunctional building in order to make optimal use of all the new space. For instance, three training rooms can be combined to create a larger space with enough seating for up to 60 people. The SCHAUFLER academy will also serve as a representative reception building for the Rottenburg production facility. &ldquo;The training courses offer a variety of benefits: BITZER can present the theory behind the added value provided by cutting-edge compressors and electronic components as well as demonstrate the practical advantages when used with new technologies and carry out testing on real systems,&rdquo; says Gro&szlig;e-Kracht.<br /> <br /> BITZER will also showcase its latest products at the SCHAUFLER academy, including the CSVH compact screw compressor and the ORBIT 6 scroll compressor in practical applications for heating and cooling. The specialist in refrigeration compressors also designed the SCHAUFLER Academy to offer space for offices for the training staff and a company restaurant with seating for 110 employees and training course participants.<br /> <br /> <b>Innovative Energy Concept</b><br /> <br /> One of the SCHAUFLER Academy highlights will be the innovative energy concept, featuring heat pumps for heating and cooling, underground latent storage (ice storage), the solar thermal collector and the block-type thermal power station. Having pursued sustainability for quite some time, the company is now demonstrating how cutting-edge environmental protection works. &ldquo;We&rsquo;re happy to assume higher investment costs for the ice storage, for example,&rdquo; says Kleiner. &ldquo;We use it to collect temporarily available cooling and thermal energy and retrieve it again when necessary. This allows us to compensate for the fluctuating energy supply and use renewable energy sources that are suitable for heating and occasionally for cooling. Of course we also use the existing waste heat released by the testing and demonstration systems.&rdquo; The concept also has additional benefits: it&rsquo;s eco-friendly, doesn&rsquo;t require any approval processes and can also be used in water protection areas.<br /> 8th EHPA European Heat Pump Forum http://www.r744.com/events/view/803 http://www.r744.com/events/view/803 2015-01-15 01:33:00 event The 8th edition of EHPA&rsquo;s annual forum returns to Brussels in 2015.
