18.4.2019 09:23:11 CEST | Business Wire | Press release
Premiering for the first time in the world, Mitsubishi Heavy Industries Thermal Systems, Ltd., a Group company of Mitsubishi Heavy Industries, Ltd. (MHI) (TOKYO: 7011), is adopting R454C, a refrigerant with an extremely low global warming potential (GWP), in a 1-horsepower (HP) class residential air-conditioner. The conventional shortcomings of the R454C,for example; inferior heat exchanger performance attributable to it being a mixed refrigerant have been overcome through the use of proprietary technology that optimize the heat exchanger’s flow volume and other measures. The company has already developed a demonstration unit of the residential air-conditioner featuring R454C and preparations are underway towards mass production with an eye on an initial launch into the European market, where environmental regulations are particularly stringent.

The R454C refrigerant has an ozone depletion potential (ODP) of 0 (zero) and a GWP of 146 (CO2 =1). The latter value is approximately 1/14th and 1/5th the respective GWP levels of refrigerants currently and most widely used in air-conditioners of small/medium scale: R410A (2090) and R32 (675). The overall global warming impact (GWP x refrigerant volume) from the demonstration unit’s refrigerant represents a 91.3% reduction from the level of MHI Thermal Systems’ previous model for the European market*1 .
Worldwide initiatives aimed at stopping global warming were strengthened in October 2016 with the adoption of the “Kigali Amendment” to the Montreal Protocol on Substances that Deplete the Ozone Layer. Named after the capital city of Rwanda where the delegates met, the Kigali Amendment mandates progressive reduction in hydrofluorocarbons (HFC), substances that do not deplete the ozone but do adversely impact global warming*2 . In addition, since 2015 the member nations of the European Union (EU), where environmental awareness is deeply entrenched, have gradually expanded regulations affecting the sale and usage of substances, including HFCs, that have GWP values of 150 and higher, contributing to global warming. MHI Thermal Systems’ development of the world’s first small-capacity residential air-conditioner adopting the R454C refrigerant is thus a leading and positive response to these international movements.
Going forward, MHI Thermal Systems will continue to dedicate its resources to developing and marketing high-performance products using low-GWP refrigerants, thereby contributing to protection of the global environment in markets everywhere.

Grafana Labs Charts the Path to Agentic Operations with Watchers, Pages, and Agent Observability at ObservabilityCON 202620.10.2026 19:00:00 CEST | Press release
Grafana Labs delivers AI for observability and observability for AI: always-on agents to operate systems, and OpenTelemetry-native visibility into the agents you ship Grafana Labs, the company behind the open agentic observability cloud, today announced new releases at ObservabilityCON 2026 that move Grafana Cloud towards agentic operations, including the general availability of Agent Observability with OpenTelemetry support and of Assistant Watchers, and previews of Grafana Pages and Grafana Managed Sandboxes. As AI moves into production, teams face two connected challenges: using agents to operate their systems and understanding the behavior of the agents themselves. In the 2026 State of Observability Report, also released this week by Grafana Labs and ETR, a Futurum company, 68% of the 300 IT and engineering leaders surveyed have moved AI for observability past investigation into pilots or production. But confidence depends on the task and readiness varies: 85% report comfort with r
Grafana Labs Brings Faster Full-text Search and Smarter Data Optimization to Grafana Cloud at ObservabilityCON 202620.10.2026 19:00:00 CEST | Press release
Adaptive Logs Archive lets teams keep more logs for less, and faster queries for rare values in Grafana Cloud Logs help them, and their agents, find what matters in seconds Grafana Labs, the company behind the open agentic observability cloud, today announced new releases at ObservabilityCON 2026 that help teams manage their telemetry in the AI era, finding the right log line in seconds and keeping only the telemetry worth paying for as AI workloads scale. Major query performance enhancements to Grafana Cloud Logs, built on technology from the company's Logline acquisition, are now generally available, and Adaptive Logs Archive is in public preview. AI is massively increasing telemetry volumes. Coding agents are turning everyone into a developer, so more software is being built, faster, and all of it needs to be watched. The agents add to the load too, since every agent call and tool call emits its own telemetry. Left alone, observability costs grow with every new workload, which makes
Nissan Technical Centre Europe Adopts Sonatus Fastlane™ Platform to Accelerate Vehicle Test and Validation20.10.2026 18:37:00 CEST | Press release
Event-driven data collection and AI-powered root-cause analysis to become standard practice for new NTCE vehicle programs; Proven to cut investigation time from two weeks to two days Following a successful proof of concept and ongoing engineering development over the past 12 months, Nissan Technical Centre Europe (NTCE), Nissan’s primary R&D hub for its global regions, is expanding its use of the Sonatus® Fastlane™ Platform across its pre-start-of-production (SOP) validation workflow. The platform’s event-driven data collection and root-cause analysis have reduced the time NTCE engineers spend investigating vehicle software issues from two weeks to two days. NTCE plans to make the platform a standard part of validating future vehicle programs, including upcoming models such as the Nissan JUKE. With the Fastlane Platform, engineers have the data they need from the moment a fault occurs. Teams deploy targeted data-collection policies from the cloud, and capture begins automatically when
