GEA introduces BOCK HGX24 CO2 T
DUESSELDORF, Germany, 08 February 2021: With the new HGX24 CO2 T range, GEA BOCK is expanding its semi-hermetic CO2 compressor range with a specialised focus on transcritical applications in the lower capacity range, the company said through a Press release.
Cooling capacities from 5 to 26 kW and heating capacities from 10 to 48 kW offer flexible stationary and mobile use in applications for supermarkets, commercial and small industrial refrigeration systems as well as for air conditioning and heat pumps in buses and trains, the company said. With their CO2-specific pressure design of up to 150 bar (HP) and 100 bar (LP) and a frequency range of up to 70 Hz, the gas-cooled compressors achieve the highest EER/COP values within their application spectrum – with up to five per cent higher efficiency in standard medium cooling compared to commercially available compressors in this segment. “The new transcritical compressors have proven themselves in extensive internal testing and in numerous field tests with our customers and will be available from February 2021 – equipped as standard with all the necessary features for use with the natural refrigerant R744,” said Manuel Fröschle, Product Manager Natural Refrigerants, GEA BOCK.
According to GEA, the advantages of the new range for planners, investors and operators include significantly reduced energy and operating costs combined with a long service lifetime with low maintenance requirements, a wide range of applications – from medium- and low-temperature applications to high-temperature heat pumps – with reliable and flexible part load, as well as excellent low-noise and low-vibration running comfort with a minimal oil carry over rate. The basis for this, GEA claimed, is a CO2-optimised driving gear design combined with BOCK compressor technology. This includes, for example, the oil pump for a reliable lubrication system even under demanding conditions, including large permissible inclination angles of the compressors.
“Together with the compact dimensions, the low weight of only 116 kg, maximum, as well as standard market connection dimensions, the HGX24 CO2 T set new standards for transcritical economic solutions for smaller performance requirements in stationary and mobile applications,” Fröschle said. “In this regard, they support the fulfillment of important energy and environmental protection requirements, such as the European F-Gas Regulation or the global Kigali Agreement, and meet strict requirements of European standards and ASERCOM guidelines.”
According to GEA, the new range is now also integrated as an additional module in the free online planning and design software BOCK VAP (compressor selection program) and BOCK CO2 Tool (system and compressor selection program).
For special subcritical requirements in low-temperature applications with high operating and standstill pressures, GEA said, the semi-hermetic BOCK CO2 compressor program will offer the specifically designed low temperature cooling variant HGX24 CO2 LT (Low Temperature) with two motor versions from June 2021.
Danfoss Press Release – Fresh food, with minimum energy
NORDBORG, Denmark, 21, January 2021: Danfoss said it has strengthened its Alsense IoT services with a holistic store-level software suite, moving store maintenance from reactive to proactive. Making the announcement through a Press release, the company said the technology enables food retailers to prioritise and reduce their maintenance efforts across stores and critical events. It added that the software solution was originally developed by Honeywell.
“We are thrilled to welcome the Smart Refrigeration Solution and incorporate it into our Alsense cloud-based services,” said Jürgen Fischer, President, Danfoss Cooling Segment. “We are now putting predictive maintenance into action, allowing the food retail industry to prevent unplanned cooling system downtime and inefficiencies in energy consumption.”
Natalie Schnippering, Head, Product Management Digital Services, Danfoss, said: “Combining the Smart Refrigeration Solution with our existing Alsense portfolio accelerates our ambition of meeting food retail customers’ needs for optimizing and proactively maintaining a high store performance. The solution goes beyond the traditional monitoring systems that are primarily providing alarms and data overviews. It identifies operating issues, such as compressor failure or coil icing, and provides hands-on guidance to fix them.”
According to Danfoss, Alsense provides food retail professionals with transparency and executive overviews of refrigeration assets and energy efficiency at chain level. Going forward, the combined Alsense offering will enable managers to easily benchmark and prioritise efforts across stores to save time and optimise the impact of their maintenance spend, Danfoss said. Further, Alsense will provide service technicians with a prioritised action plan, empowering them to immediately address equipment performance and operating concerns upon arrival at a store, Danfoss added.
Chris LaPietra, Vice President and General Manager, Honeywell Stationary Refrigerants, said, “The Smart Refrigeration Solution software was developed based on customer requirements gathered from leading food retailers, who were looking to save money by reducing energy spend and improving performance of their refrigeration system.”
According to Danfoss, the step follows the launch of its Alsense IoT platform in October 2020 and will accelerate its efforts in providing food retail professionals with intuitive software tools and data-driven, expert-enabled insights to optimise operational efficiency, refrigeration asset performance and energy efficiency.
