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.

Shecco to host annual trade show on natural refrigerants

BRUSSELS, Belgium, 05 February 2021: Clean Cooling market accelerator, shecco has opened free registration for its second Virtual Trade Show (ATMO VTS 2021) for natural refrigerant and sustainable cooling technologies, the body said through a Press release. The registration page can be found here, it added.

According to shecco, the event, designed for the global refrigeration, air conditioning and heat pump industry, will take place over a 24-hour period, from 10 am CET (Central European Time) March 30 to 10 am CET March 31. The show is designed to fill the physical trade show void, as the world continues to grapple with the COVID-19 pandemic, shecco added.

shecco said it is expecting 5,000-10,000 registrations and more than 100 exhibitors of natural refrigerant products for ATMO VTS 2021. Premium exhibitors so far include Teko, Zudek, ebmpapst, Carel, Alfa Laval and Dorin, it added.

The inaugural ATMO VTS took place from September 1 to 2, 2020, shecco said, adding that it attracted 77 natural refrigerant companies as exhibitors and more than 4,200 attendees from 1,500+ organisations from around the world.

“ATMO VTS 2021 will give that ‘real’ trade show feeling, which is much needed these days,” said Marc Chasserot, CEO, shecco. “The platform allows us to explore different halls, listen to live presentations, and make valuable connections with customers and suppliers from all over the world.

“In addition to some great exhibitors, with more signing-up each week, we’ve made some big changes, including new Product Innovation Awards and 24 hours of live webinars, including panel discussions, so that everyone, no matter where you are in the world, can listen live to some key discussions from cooling thought leaders.”

The live webinars will include presentations on shecco’s first Annual Report on the natural refrigerants industry, global training, the new EU F-Gas Regulation update and food retail experiences from around the world.

ACR Project Consultants aims to drive Green cold chain applications across India

Arvind Surange

Pune, India, 19 March 2019: ACR Project Consultants has placed a strong focus on the cold chain sector over the last 30 years, said Arvind Surange, CMD. It was while working on large number of cold chain projects, Surange said, that the company realised the need for integrating Green design concepts in the sector. “We introduced this concept in 2008 and have been promoting it at a global level, highlighting the importance of environment friendliness, energy efficiency, water saving, waste heat recovery, application of renewable energy and other green features,” he said.

Surange said that realising the importance of natural refrigerants, ACR took the lead in designing the first few low-charge Ammonia DX systems in India for cold storage projects. He said: “The basic features of these are: Ammonia charge reduction; compact and lightweight equipment; full automation, including use of electronic expansion valve; and air-cooled or water-cooled setup, based on water availability.

Providing an example of one of the company’s Green projects, Surange pointed to the integrated cold chain facility of Savla Foods and cold storage in Navi Mumbai, which includes recycling of water, waste heat recovery for generating hot water for processing, along with other Green features. He added that the project was named Best Green Cold Chain Solution by the Cold Chain and Logistics Industry in 2017 and Best Food Processing and Cold Chain Project by RefCold India Emerson Awards in 2018.

In addition to this, Surange said, the latest projects the company is working on involve PEB structure with insulated panel enclosures, mechanised loading and unloading systems, eco-friendly and energy-efficient refrigeration and electrical systems, water-saving techniques and full automation. “These projects,” he said, “have been implemented in right from the northern to the southern and from the eastern to the western regions of the country.”
