CAREL UK figures exceed expectations http://www.r744.com/news/view/5638 http://www.r744.com/news/view/5638 2014-09-02 10:21:26 article CAREL UK has released its latest figures which reveal significant growth. Numbers show that at the end of the first half of this year it was ahead of its 17% growth target and is on track to deliver 65% growth from 2013-15.<br /> <br /> Last year the company launched a three year plan, following the appointment of key management personnel. Following a period of little growth during 2011-2012, it appointed Bob Cowlard as managing director in June 2013. He was joined by Nigel Hillier as national sales manager (NSM) in the Climate Division and Richard Hay as national sales manager for Retail and Refrigeration. CAREL UK says that these appointments have served as a catalyst for a new focus on customer service and technical solutions.<br /> <br /> These three key management appointments joined Jesse Poulter, national sales manager for HVAC OEM and Steve Chapman, responsible for Service and Contracts, to reposition the company, which had long depended on its manufacturing and OEM business. The internal Order Processing and Technical Support teams have been strengthened along with an increase in marketing activity and this shift of emphasis has quickly translated into financial success with 2013 closing at 18% growth and a return to healthy profitability. The latest figures show that this positive trend is continuing into 2014: after only seven months, growth stands at 21% against a target of 17% for the year. UPDATE: ATMOsphere Europe 2015 kicks off in March, registration now open http://www.r744.com/news/view/5077 http://www.r744.com/news/view/5077 2014-09-01 14:43:22 article Taking place for the sixth time, ATMOsphere Europe 2015 &ldquo;Natural Refrigerants &ndash; Solutions for Europe&rdquo; is the forum for HVAC&amp;R industry experts to discuss the latest natural refrigerant technology developments, regulatory updates and market trends. Key topics featuring at the event include CO<sub>2</sub> applications for commercial, light commercial, industrial &amp; transport refrigeration, heat pumps, air conditioning and more. <span style="color: rgb(255, 0, 0);">+ Registration for the event has officially opened with an Early Bird Special rate available until 15 October 2014.</span> BITZER Highlights at Chillventa 2014 http://www.r744.com/news/view/5637 http://www.r744.com/news/view/5637 2014-09-01 11:58:31 article BITZER, specialist in refrigeration compressors, showcases its key 2014 innovations at the international trade fair in Nuremberg.<br /> <br /> BITZER Highlights at Chillventa 2014<br /> <br /> <ul> <li>Reciprocating compressors: new CO<sub>2 </sub>series and CRII capacity control</li> <li>Screw compressors: CSVH3, CSVW2, expanded OS series</li> <li>Scroll compressors optimally combined: BITZER Advanced Header Technology (BAHT)</li> <li>Condensing units: LHE, ECOSTAR</li> </ul> <b><br /> Sindelfingen, 28.08.2014. </b>Chillventa 2014 visitors can look forward to a whole host of innovations at BITZER&rsquo;s trade fair stand (Hall 4, Stand 310 and 408), which measures around 500 square meters.<br /> <br /> One of the many new products the compressor specialist will be showcasing in Nuremberg is the further optimized CRII capacity control. The system delivers virtually infinitely adjustable capacity control for the ECOLINE reciprocating compressors with four, six and &ndash; now for the first time &ndash; two cylinders.<br /> <br /> <b>CRII: low operating costs thanks to efficient compressor control</b><br /> <br /> Depending on the operating 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 two-, four- and six-cylinder compressors. The increased switching frequency, however, ensures smaller fluctuations in controlled value, temperature as well as pressure and, in combination with the expanded range of control, optimizes system efficiency.<br /> <br /> Volker Stamer, BITZER Director of Sales for Stationary Products, explains: &ldquo;With the CRII system, we are offering our customers a whole new level of flexibility and supporting customization to suit all possible ECOLINE compressor operating conditions. This increases system efficiency whilst protecting the environment.&rdquo;<br /> <br /> <b>Further steps in efficiently creating refrigeration with CO<sub>2</sub> compressors</b><br /> <br /> BITZER is also always expanding its range of CO<sub>2</sub> compressors. With the introduction of the 4PTC-6K model for lower displacements and the 4DTC-25K and 4CTC-30K models for higher displacements, the series for transcritical compressors now ranges from 4.3 to 25.6 cubic meters of displacement per hour at 50 Hz. Chillventa trade fair visitors can look forward to an expanded product range and a new CO<sub>2 </sub>series at the BITZER stand.<br /> <br /> <b>World premiere in screw compressors<br /> </b><br /> For the first time, BITZER is presenting a new, eye-catching open-drive screw compressor in the OS series to the public. The model is based on the tried-and-tested construction of the OS series and, for now, is designed for use with NH<sub>3</sub> (ammonia) in medium and low temperature applications. BITZER therefore offers the refrigeration and air conditioning industry a compressor solution tailored to meet the requirements of industrial applications. Further models for industrial applications are already in development.<br /> <br /> <b>Greater cooling capacity with CSVH3 compact screw compressors</b><br /> <br /> The CSVH3 series is a new development in the field of regulated speed-regulated compact screw compressors. BITZER has added two significantly more powerful larger models to its existing CSVH series. The CSVH37 compact screw compressor has a cooling capacity of 550 kW (+5/50&deg;C) with a displacement of up to 960 m3/h. The larger CSVH38 possesses an impressive cooling capacity of 660 kW (+5/50&deg;C) with a displacement of up to 1,156 m<sup>3</sup>/h. BITZER has developed a new housing size to achieve this level of performance. The series is based on the proven engineering and electronics of the CSVH2 series and has a very wide range of applications, from air cooled liquid chillers to heat pumps.<br /> <br /> The CSVW2 is also a compact screw compressor, specially designed for liquid chillers with a low condensing temperature. Its engineering is based on the tried-and-tested CSVH2 compact screw compressor and combines proven strengths with new capabilities at low load conditions. In order to achieve a high coefficient of performance (COP) for this type of application, and thus a good ESEER, BITZER has integrated a permanent magnet motor. The innovative drive technology is beneficial particularly in liquid chillers with a water cooled condenser. The internal volume ratio (Vi) of the compressor was also adjusted to allow the CSVW2 series to achieve much better efficiency in the lower speed and load range than the CSVH series. BITZER modified the frequency inverter accordingly.<br /> <br /> <b>Scroll compressors optimally combined</b><br /> <br /> In the scroll compressor segment, the new BITZER Advanced Header Technology (BAHT) for compressor tandems and trios is pioneering in the design of air conditioning and heat pump systems.<br /> <br /> The newly developed suction gas header plays a key role, as it specifically directs oil to one of the compressors and then, inside the compressor tandem or trio, distributes it evenly among the other compressors. The system even works when uneven compressors are combined and allows the frequency of a single compressor to be adjusted in the unit. The unit does not require active oil management with an oil separator or a lead compressor into which the oil can flow back. Even when one or two compressors are shut off, oil distribution is maintained.<br /> <br /> BITZER Advanced Header Technology offers the following benefits:<br /> <ul> <li>Only one suction line for many compressor combinations without an individual combination of restrictor washers</li> <li>Reliable functioning at high and low suction gas volume flows</li> <li>Uneven capacity adjustment through different displacements in the unit</li> <li>Different compressor housing sizes (GSD6 and GSD8) can be combined in one unit</li> <li>Less warehousing, simpler installation and error prevention in the production of multi-compressor units</li> </ul> <br /> The lower oil carry over rate of the ORBIT scroll compressors and the new suction gas header promote longer operation with equalized oil levels in the compressors, even in demanding conditions, including the integration of reversible heat pumps and iced evaporators. The oil needs to be able to return to the suction line.<br /> <br /> Well equipped for the future: ECOSTAR and LHE condensing units<br /> <br /> The new air cooled LHE condensing units are worth taking a look at, as they already fulfill the European Union&rsquo;s ErP Directive (Energy-related Products Directive) &ndash; the so-called Ecodesign Directive. The Association of European Refrigeration Compressor Manufacturers (ASERCOM) confirms the high standards of the LHE condensing units. The first LHE products have already received the newly created ASERCOM certification for condensing units. Like the optimized ECOSTAR condensing units, they too represent another highlight at the BITZER trade fair stand.<br /> Volker Stamer, BITZER Director of Sales for Stationary Products, notes: &ldquo;We are proud to be able to showcase our latest innovations at Chillventa 2014 and look forward to chatting with visitors. It&rsquo;s well worth a visit, as we have a whole lot more in store.&rdquo;<br /> <br /> <b>About Bitzer</b><br /> <br /> The BITZER Group is the world&rsquo;s largest independent manufacturer of refrigeration compressors with sales companies and production sites for reciprocating, screw, and scroll compressors as well as pressure vessels all over the globe.

Growth in the world heat pump market http://www.r744.com/news/view/5633 http://www.r744.com/news/view/5633 2014-08-29 09:50:12 article The world heat pump market increased 7.2% by volume in 2013 to almost 2 million units. The growth was driven by the strong progression of sales of heat pump water heater in the USA especially on the one hand, and the recovery of the European market on the other hand.<br /> <br /> However, in value terms, the market went down 6.9% in 2013 compared with 2012; the reason behind the drop is attributed to the decrease in sales of large output units as well as increasing competition among suppliers.<br /> <br /> In 2013 there was an increasing penetration of air-to-water cylinder integrated units, also known as heat pump water heater, following almost 40% growth in 2012, the world market posted a 26.5% growth in 2013. However this growth was mainly outside of Europe, within Europe the market size remained limited to a few thousand units.&nbsp;<br /> <br /> Among the other air-to-water types, split systems continued to enjoy wide popularity, growing 15.6% globally. These units are dominating the sales in Europe notably, with small capacity products accounting for a significant share of the market. The growth appears to have taken place at the expense of monobloc systems, the volume of which decreased by 2% in Europe overall. The global demand for split unit systems was counterbalanced in China where sales of monobloc heat pumps accelerated by 13.8% resulting in a positive 5.1% growth worldwide.<br /> <br /> Poor performance in the geothermal heat pump segment was again recorded at a global level in 2013. Despite a 5% rise in the USA and China markets, the sales declined within Europe resulting in a reduced volume of 1%. High initial investment and lack of political support are stated as the major obstacles to the development of the ground-water heat pump market by suppliers.<br type="_moz" /> <br /> PTC+ http://www.r744.com/companies/view/ptcplus http://www.r744.com/companies/view/ptcplus 2014-08-29 00:00:00 company PTC+, based in the Netherlands, specialises in enhancing knowledge, skills and promoting entrepreneurship via the operation of targeted &quot;learning by doing&quot; expertise centres.

Pick n Pay exceeds carbon emissions reduction goals http://www.r744.com/news/view/5617 http://www.r744.com/news/view/5617 2014-08-25 16:34:26 article Pick n Pay has more than achieved its target on reducing carbon emissions set in 2010 &ndash; a full year ahead of schedule. The company is now focusing on reducing emissions further, through greater in-store energy efficiency and other means.<br /> <br /> David North, Group Strategy and Corporate Affairs Director at Pick n Pay, explains that reducing carbon emissions in stores and distribution centres has been a key sustainability goal for Pick n Pay for a number of years: &ldquo;In 2010, Pick n Pay set a target to reduce carbon emissions by 15% by 2015. We have met and exceeded this goal ahead of our target date. Measured against our 2010 baseline of stores, our emissions have already been cut by 19.4%. We reduced carbon emissions per square meter by 4% in 2013 alone,&rdquo; says North.<br /> <br /> Pick n Pay is also focusing on reducing fugitive emissions from refrigerant and air-conditioning gases. &ldquo;We are addressing the environmental impacts of fugitive emissions in two ways: by reducing the amount of leakages and by replacing the gases with less harmful alternatives. For example, 20% of our corporate stores use CO2 for refrigeration, while almost all our new stores opened in 2013 used a combination of CO2 and other gases, with much lower global warming impact.
