INDUSTRIAL ELECTRIC MOTORS


Motor range to cover smaller applications


Three smaller frame sizes (90, 100, and 112) have been added to ABB’s IE5 synchronous reluctance motor (SynRM) portfolio, extending the power range from 0.75 kW to 450 kW. The motors are magnet- and rare earth- free and are designed for applications such as pumps, fans, and compressors. They offer speed options up to 3600 RPM and can be paired with ABB variable speed drives for controlled, efficient operation. ABB reports that IE5


SynRM motors reduce energy losses by up to 40% compared with IE3 motors, with payback periods often under six

months. For example, a single 90 kW motor could save roughly €79,800 and cut CO₂ emissions by approximately 95,760 kg over 20 years. The motors are suited to continuous- duty or space-constrained environments where efficiency under partial load, thermal performance, and precise control are important. The motors are part of ABB’s EcoSolutions


portfolio, which provides transparency on the environmental impact and circularity of products. This portfolio includes third-party verified Environmental Product Declarations under ISO 14025 Type III, supporting informed decision-making for sustainability and efficiency in industrial


operations. ■ www.abb.com


The range of air cooling equipment for data centres from TRANE has been expanded with the launch of new Computer Room Air Handlers (CRAH) and Fan Wall Units (FWU). The CRAH units are available in several configurations and provide up to 260kW of cooling capacity per unit, while the Fan Wall units can deliver up to 600kW, supporting a variety of co-location and hyperscale data centre applications. Both ranges incorporate variable speed fans and heat exchangers with hydrophilic coatings. These units are designed to work alongside Trane’s Sintesis air-cooled chillers and XStream water-cooled chillers, which are available in mega-watt sizes and use HFO refrigerants with low global warming potential. The modular design of the CRAH


and Fan Wall units allows for scalable deployment and flexibility in different data centre layouts. Key components, including EC fans, pressure-independent valves, and integrated control technology, are designed to maintain consistent temperature control and


operational reliability while optimising energy efficiency. The units are intended to provide a coordinated airside solution when paired with Trane’s chillers, enabling adaptable cooling capacity and system


integration. ■ www.trane.eu


COOLANT DISTRIBUTION UNIT HEAT PUMP


Heat pump technology that copes with regulatory change


Designed for commercial and light- industrial use, WEATHERITE’s new R290 heat pump provides an option for businesses looking to adopt low-GWP refrigerants. The system has been developed to run on propane (R290), a natural refrigerant, in response to regulations that are phasing down synthetic refrigerants with higher global warming potential. The system incorporates fully hermetic


compressors, optimised heat exchangers and an advanced defrost cycle intended to improve performance in varying weather conditions. It also includes a safety architecture that is designed to reduce risks associated with the flammability of propane, addressing one of the main

barriers to wider adoption of R290-based systems. The proprietary safety system provides


layered protection, not just during routine operation, but also during maintenance and any abnormal conditions that may arise, offering peace of mind to facilities managers and HVAC engineers alike. In parallel, the intelligent defrost cycle


ensures superior stable performance in real-world weather conditions, reducing system downtime and energy waste. The result is a robust, high-performing system designed for retail, commercial, and light- industrial environments where heating and cooling demand is both constant and


critical. ■ www.weatheritegroup.com


Liquid cooling platform boosts efficiency in high-density computing


JOHNSON CONTROLS has launched the Silent-Aire Coolant Distribution Unit (CDU) platform, a liquid cooling system designed for high-density data centre environments. The units offer scalable cooling capacities ranging from 500kW to over 10MW and can be installed within rack rows or in the perimeter whitespace of a facility, providing flexibility to suit a variety of deployment layouts.


The Silent-Aire CDUs deliver precise and efficient cooling for a broad range of setups, from edge inference deployments to large AI training facilities. By enabling targeted thermal management, the system helps data centre operators reduce non-IT energy consumption by more than 50%,


supporting operational efficiency and sustainability objectives. The platform’s design accommodates


both new and existing data centre infrastructures and can be configured in hybrid liquid-cooling arrangements, allowing integration with other cooling technologies. Johnson Controls says that the Silent-Aire CDUs are engineered to manage the increasing heat loads of next-generation computing hardware while maintaining consistent performance, reliability, and energy efficiency. This makes the units a scalable solution for organisations seeking to support high-density racks without compromising operational


standards or environmental goals. ■ www.silent-aire.com/cdu
