Chart Industries’ IPSMR natural gas liquefaction process has become one of the company’s signature offerings for mid-scale LNG export and peak-shaving plants, combining proprietary mixed-refrigerant technology with compact cold boxes aimed at cutting energy use and project footprint. At a time when global LNG investment remains robust following Europe’s scramble for non-Russian gas, IPSMR is positioned as a flagship solution in Chart’s portfolio, used in multiple projects from North America to Asia.

How Chart’s IPSMR process works and where it is used

IPSMR is Chart’s integrated pre-cooled single mixed-refrigerant cycle, designed to liquefy natural gas using a single mixed-refrigerant loop and plate-fin heat exchangers packaged in an aluminum cold box. According to the official Chart IPSMR product description, the process targets mid-scale LNG capacities with typical train sizes of roughly 0.2 to about 1.5 million tons per year per train, depending on configuration and ambient conditions. The company highlights that IPSMR can be deployed in onshore export terminals, floating liquefaction projects and utility peak-shaving plants, and that the compact cold-box design can lower plot space and field work compared with stick-built systems. Chart’s own IPSMR process page describes the technology as a proprietary mixed-refrigerant cycle combining efficiency and modularity.

Chart emphasizes that IPSMR’s pre-cooled single mixed-refrigerant configuration is engineered to deliver high thermodynamic efficiency, which can translate into reduced power consumption per ton of LNG and potentially lower operating costs over the plant lifetime. The process packages the core cryogenic equipment, including plate-fin heat exchangers and associated piping, into factory-assembled cold boxes that are shipped to site, a modular approach intended to compress construction schedules and reduce onsite labor. The company also notes that IPSMR can be integrated with different gas pre-treatment solutions and power-generation choices, giving developers some flexibility in tailoring projects to local gas quality, grid conditions and emissions targets.

Real-world deployments underpin IPSMR’s flagship status in Chart’s LNG portfolio. In 2022 Chart announced that it would supply its IPSMR liquefaction technology and cold boxes to Freeport LNG’s planned fourth liquefaction train at the Texas export facility, a mid-scale expansion designed to add roughly 5 million tons per year of capacity. In its Freeport communication, Chart pointed to prior IPSMR references in smaller-scale export and peak-shaving applications, arguing that the same architecture scales for brownfield expansions and new-build projects. The company has also cited IPSMR orders from Asia and the Middle East for city-gas utilities seeking to secure peak winter supply or balance pipeline constraints, underlining that the process is not limited to large coastal export terminals.

Beyond the core process, Chart increasingly bundles IPSMR with related cryogenic equipment and services, including brazed aluminum heat exchangers, LNG storage tanks, loading systems and lifecycle maintenance contracts. This systems approach allows the company to capture more value per project while giving customers a single point of responsibility for much of the liquefaction island. Chart’s marketing materials stress that IPSMR-based packages can be adapted for different feed-gas compositions, carbon intensity goals and space-constrained locations such as brownfield industrial sites or floating units, and that the company’s global fabrication footprint supports delivery to North American, European and Asian projects.

Strategically, IPSMR sits at the heart of Chart’s LNG and clean energy segment, a business that management has repeatedly described as a key growth driver as the company seeks to benefit from long-term demand for lower-carbon fuels and flexible gas supply. In its recent investor presentations, Chart has highlighted a multi-billion-dollar commercial pipeline for LNG and hydrogen projects and pointed out that proprietary technologies such as IPSMR can support margin resilience against commodity equipment competition. Shares of Chart Industries (ISIN US16115Q3083) traded on the NYSE at around $135 on 06/14/2026, reflecting a business that investors closely associate with LNG and broader energy transition infrastructure.
