The two models, 350 and 400, with a flow volume of 321 and 372 m³/h (at 2,940 rpm), extend the semi-hermetic screw compressor series from larger to medium and also smaller capacity requirements, the company said.

They combine best efficiencies by using the natural refrigerant, ammonia, a wide, stepless adjustable, variable internal volume ratio and a wide speed range as well as highest safety and reliability through decades of experience in developing screw compressors, the company claimed.

The compact design and the simultaneously high degree of integration also make the CompaX a cost-efficient and space-saving product, the company further claimed.

In the introductory phase, the 350 and 400 models are available as both packages and chillers, the company said. The new Grasso X semi-hermetic screw compressor packages offer maximum flexibility and efficiency with a minimum footprint and overall cost, the company said. Customers can choose between a single version and a multipackage. The multipackage can optionally be configured by the customer with two, three or four identical CompaX 350 or 400 units in parallel arrangement, the company added.

Combined with the wide speed range of each screw compressor, the Grasso X setup provides availability, redundancy and efficiencies at the highest level over nearly the entire full and part load range, the company claimed. Refrigeration capacities range from approximately 200 to 1,900 kW (NH3, -10/+35 °C), it added.

The existing BluX semi-hermetic chiller series is also extended by the new compressors, the company said. The BluX includes all the features and benefits of the unit. The proven, state-of-the-art heat exchanger set completes the product to a compact, highly efficient and safe plug-and-play solution, the company claimed. With refrigerant inlet and outlet temperatures of +12/+6 °C and condensing at ambient temperatures (+35 °C), the BluX capacity range extends from approximately 350 kW cooling capacity with 1x CompaX 350 at 3,000 rpm to circa 1,530 kW with 2x CompaX 400 at 6,000 rpm, the company said. Larger capacities are covered by the GEA BluX with the existing large CompaX 700 and 900 types, it added.

“The compact, safe and reliable products, in combination with their high efficiency, lead to reduced total costs and a most sustainable solution,” said Ron Hoffmann, Product Manager for screw compressors, GEA. In addition, GEA systems require a minimum of maintenance. “We like to convince our customers with the performance and efficiency figures of our machines, Hoffmann said. “We are happy to bring over 50 years of expertise in the development and production of screw compressors to the market with our proven and new products.”

GEA speaks of improving plant efficiency, reducing carbon emissions

DUESSELDORF, Germany, 12 February 2021: Potential energy savings of up to 30% and a significant reduction in CO2 emissions by as much as 90% or even 100% – that’s what its Sustainable Energy Solutions (SEnS), which integrates processes and utilities (refrigeration and heating) solutions, can help in developing optimisation strategies for customers in diverse industries, GEA said through a Press release. Numerous successfully completed SEnS projects from GEA show that these optimisations reduce the customer’s energy footprint and running costs, without compromising output or the bottom line, GEA added.

According to the United Nations, energy efficiency offers a potential 40% of the emission reductions required to help meet global climate goals, GEA pointed out. Due to a growing number of rules and regulations and its own climate targets, there is an absolute need for the industry to reduce its carbon footprint and become more energy-efficient, overall, it said. With cooling and heating traditionally accounting for anywhere between 50% and 90% of a plant’s entire energy consumption, it’s the ideal starting point for GEA’s SEnS initiative, it added.

GEA said its SEnS offering is a culmination of a broad processing portfolio and years of industry know-how, combined with extensive refrigeration expertise. “SEnS supports customers in the food processing, dairy and beverage industries, helping them achieve their climate goals by making them more sustainable,” said Kai Becker, CEO, Refrigeration Technology Division, GEA. As a global industrial technology provider, GEA said, it will continue to strengthen its SEnS offering in 2021. Using the SEnS approach, GEA said it will promote the increased adoption of sustainable solutions, which drive down energy consumption and reduce carbon emissions while helping customers from diverse industry sectors slash their operational costs.

Ulrich Walk, Chief Service Officer (CSO) – Refrigeration Technologies, said: “GEA has developed a structured holistic and proven approach that begins with analysing the customer’s precise energy requirements, then making process optimizations and including utilities in the equation. By connecting heat pump technology to manufacturing processes, the GEA experts ensure energy is moving circularly, rather than being wasted.”

According to GEA, each SEnS project includes a single point of contact, enabling customers to achieve genuine and proven reductions in energy consumption and their carbon footprint. The SEnS process, the company said, is backed up by a cross-functional engineering team, with experts from dairy, food or beverage processing, as required, as well as team members with refrigeration (heating & cooling) expertise in diverse processing industries. Each project, it added, considers the customer’s business parameters and ambitions, formulated as measurable KPIs, against which the installation must deliver.

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.
