 More and more customers in Asia are placing their trust in BITZER quality. Take, for instance, the joint venture Pyramid Wilmar in Colombo, Sri Lanka, which in May 2017 began installing ten ECOSTAR LHV7E. Thanks to the reliable condensing units, it’s now possible to refrigerate perishable goods such as edible oils even in the local climate with its tropical temperatures, whilst ensuring fail - safe energy - efficient operation.

  Boxes containing ten BITZER ECOSTAR condensing units are lined up in front of the Pyramid Wilmar’s cold room in Colombo. The technicians of the Iceman Group of Companies have already opened up one of the boxes and are using it as a shelter from the sun. With endless blue skies and an outside temperature of nearly 35°C, a place in the shade is always welcome. Kwan Chee Wei, General Manager of BITZER South East Asia, and Jan Grübel, Market Sector Expert Commercial Refrigeration at BITZER in Sindelfingen, are working with the technicians of the Iceman Group of Companies to commission the five ECOSTAR. ‘Since 2009, we already installed over 200 of our reliable ECOSTAR in Sri Lanka. But this is our first project with the latest generation of the ECOSTAR LHV7E condensing units installed in the Master-Slave mode,’ says Kwan Chee Wei. ‘Our job is to install reliable fail-safe refrigeration and, because our long-standing distributor, Iceman, has lots of positive experience in coldroom, they’ve also opted for our tried-and-tested quality here for such large coldroom with ECOSTAR. Total ten ECOSTAR will be used to refrigerate two separate cold rooms, with five condensing units installed in each rooms, four units ECOSTAR installed as Master-Slave Mode and one ECOSTAR as standby unit.’ Their ECOLINE VARISPEED reciprocating compressors operate with R134a refrigerant.

  Low starting current plays a key role BITZER and the Iceman Group of Companies have already implemented many successful projects together. Prasadini Thamel, who is an engineer at the Iceman Group of Companies and responsible for the Pyramid Wilmar project, is sitting on a box that until recently held a packaged unit of R134a refrigerant. ‘For us, BITZER is a reliable partner whose high-quality products cover the requirements of our customers to perfection,’ she says. ‘We’ve opted for the new generation of ECOSTAR for a variety of reasons. Here in Sri Lanka, we need to be able to rely on seamlessly operating refrigeration regardless of the voltage quality in the power supply system.’ One of the key benefits of the LHV7E is the very low starting current, which not only relieves the power supply system, but also allows the end customer to double its cooling capacity. Thanks to the new ECOSTAR condensing units, the existing voltage quality can now power two cold stores rather than just one. And the customer can refrigerate double the volume of goods – 2,000 metric tons instead of 1,000.

  BEST Software for user-friendly operation The new ECOSTAR is highly valued by BITZER customers throughout Asia and this success story can now live on with the revised version. ‘The BITZER ECOSTAR condensing units of the next-generation LHV7E boast internal ECOLINE VARISPEED reciprocating compressors and require, for instance, less refrigerant than their predecessor. They’re also extremely energy efficient,’ says Kwan Chee Wei. BITZER has also optimised the LHV5E and LHV7E models in accordance with the F-gas Regulation and the EU’s Ecodesign Directive, and approved them for HFO/HFO blends. These were just a few of the aspects that ultimately convinced Prasadini Thamel to opt for the new ECOSTAR. ‘It was also the ease of use that made the BITZER ECOSTAR the obvious choice for us,’ she says. ‘The user-friendly, easyto-use BEST Software in particular was an important factor for us – and the Bluetooth connection, which even works over a distance of 30 metres,’ Prasadini Thamel adds. In the future, she’s also planning to connect the ECOSTAR units to the Internet, allowing her to more precisely monitor their energy efficiency. ‘Just after commissioning the five ECOSTAR, Jan Grübel from the BITZER headquarters in Germany trained us on how to use the BEST Software correctly,’ says Prasadini Thamel. ‘That’s a great help for my colleagues and me when it comes to future projects.’ She’s fully satisfied with the project. So satisfied, in fact, that there are plans to install additional ECOSTAR applications in other coldroom projects.  Some of them already concrete: The Sri Lanka’s government, Food Commissioner’s Department  is already planning to install another eight BITZER ECOSTAR to store rice grain in Meerigama, 30 kilometers away from Colombo, Sri Lanka.
