Natural Refrigerants
High durability and performance
AFTER THE SUCCESSFUL market launch of the transcritical CO2 Bock compressor HGX24 CO2 T, Bock has undertaken further development.
The 4-cylinder CO2 compressor HGX24e CO2 LT, which has been available since May 2021, op- erates in six displacement stages and is available in the motor sizes ML and S.
It offers a wide frequency range and greater op- erating limits, which increases operational flexi- bility. At the same time, risks, susceptibility to faults, operating and service costs are reduced. High efficiency, quality and reliability are also strengths of the new subcritical CO2 compressor.
Climate-friendly and flexible in use, it is ideal for booster and cascade applications in commer- cial and industrial food refrigeration.
In CO2 refrigeration sys- tems, high pressures are not unusual and require a precise consideration of operating and standstill pressure to ob- tain the optimum design for the respective application.
The new Bock LT series can easily cope with higher standstill pressures that exceed the low- pressure range of 40 or 30 bar, because it is de- signed for pressures on the low-pressure side (LP) of up to 100 bar.
BOCK has addressed this issue with the LT compressor series for these special specifica- tions in low temperature applications.
The subcritical HGX24e CO2 LT operates
HGX24e CO2 LT uses R744.
highly efficiently at evaporating temperatures between -50 °C and 0 °C and condensing tem- peratures of up to 25 °C.
With a cooling capacity of 8 to 23 kW, the com- pressor offers performance in the small to medium capacity range with particularly high durability.
The HGX24e CO2 LT uses the natural refriger- ant R744 and the max permissible pressures of the compressors are LP/HP 100/100 bar.
Copeland celebrates centennial
EMERSON IS CELEBRATING the 100th anni- versary of its Copeland brand this year.
Copeland is a name that has become synony- mous with leadership in the design and manufac- ture of energy efficient, reliable compressors to power air conditioning and refrigeration systems.
It is a milestone that Emerson will recognise over the next 12 months as the company contin- ues to innovate advanced Cope- land products to solve critical
industry challenges. Reinforcing its commit-
ment to continue Copeland innovation and intense fo- cus on solving critical cus- tomer problems, Emerson completed a multimillion- dollar expansion of its Cope-
land engineering facility in Ohio, United States.

This investment created 110,000 square feet of new engineering lab space for product research, development and testing of the next generation of compressors, electronics and other critical tech- nologies for the global heating, ventilation, air conditioning and refrigeration (HVACR) industry.
Much of the work in these labs focuses on inno- vative compressor technologies that enable more environmentally responsible refrigerants with lower global warming potential (GWP) to meet and exceed efficiency standards and regulations while empowering success in customer designs.
This investment is the latest addition to Emer- son’s global network of R&D and customer solu- tions centres, which are also in China, United States and Germany.
Emerson’s commercial & residential solutions business executive president, Jamie Froedge, said air conditioning and refrigeration technol- ogies are increasingly crucial and necessary

foundations of daily life around the world.
“Through our Copeland
brand and our inventive
approach, Emerson is us-
ing our stewardship posi-
tion and deep history in this space to drive inno- vation for a more sustainable world.”
The Copeland brand traces its history to inven- tor Edmund Copeland, who founded a company in Detroit, Michigan, in 1921 to transform the re- frigeration industry with his unique inventions.
When Emerson acquired Copeland in 1986, it continued to honour the spirit of enterprise and inventiveness embodied by the brand’s early founder and champions.
Emerson made significant investments in the development of a new scroll compressor product Copeland was working on at the time of the ac- quisition and, in 1987, introduced the first scroll compressor sold under the Copeland brand. ✺
