Mitsubishi Heavy Industries is expanding overseas sales of its ETI-W high-temperature centrifugal heat pump, which has been sold in Japan since 2025. The system can produce hot water up to 90°C and has a stated maximum heating capacity of 640 kW; overseas customer availability, pricing and sales volumes have not been disclosed.
Mitsubishi Heavy Industries is expanding sales of its ETI-W high-temperature centrifugal heat pump to overseas markets, taking a system already available in Japan to industrial and commercial customers abroad. The unit is designed to recover low-temperature waste heat and produce hot water at temperatures up to 90°C, with applications including factory processes and building heating.
The ETI-W uses HFO-1233zd(E) refrigerant and has a maximum heating capacity of 640 kW, according to Cooling Post. MHI has sold the heat pump in Japan since 2025. The company’s overseas focus is expected to include electronics, automotive, food, chemical and pharmaceutical factories, as well as commercial and accommodation facilities.
MHI describes ETI-W as a heat-recovery system that captures low-temperature heat from production processes and raises it to a level suitable for hot-water use. In facilities with chillers, the system can also be configured to recover heat carried in the chillers’ cooling water and reuse it to provide high-temperature water.
Cooling Post reports that the heat pump achieved a coefficient of performance of 4.01 during heating while supplying water at up to 90°C. That figure is a reported performance result; the supplied material does not specify the test conditions or say whether it represents performance across all operating environments.
Waste Heat for Factory Processes
Expanding the product beyond Japan gives industrial and building operators another option for turning heat that would otherwise be rejected into useful hot water. Where a site has suitable waste-heat sources and demand for high-temperature water, recovery may reduce the need to generate that heat separately. The actual energy and cost effects would depend on site conditions, system design and operating patterns.
The proposed applications include sectors with process-heating needs, alongside commercial buildings and accommodation facilities. MHI also identifies data centres as a possible use: recovered heat could serve heating and hot-water demand. That use depends on whether a facility has a practical heat source, compatible temperatures and a nearby or on-site use for the recovered heat.

From Japan to Overseas Markets
MHI developed ETI-W for the Japanese market, where it has been available since 2025. Cooling Post previously reported in October 2025 that the company had developed a centrifugal heat pump capable of supplying hot water at 90°C. The current development is the planned expansion of sales to overseas markets, rather than a newly announced change to the unit’s stated temperature or capacity.
MHI Thermal Systems says it will offer thermal solutions tailored to each customer’s circumstances. That points to site-specific configuration, including possible integration with existing chillers, rather than a single standard arrangement for every application. The source does not name the countries or regions included in the sales expansion.

Sales Regions and Performance Details
The source material does not identify which overseas markets will receive the product first, when sales will begin in each country, or whether the expansion is already producing orders. It also gives no pricing, sales targets, installation figures or details of distribution and service arrangements.
The reported COP of 4.01 is not tied to stated test conditions, and no seasonal performance data or independent verification is provided. The actual output and efficiency at a given site will depend on factors such as source-water temperature, required hot-water temperature and system integration. MHI’s description of potential applications does not confirm installations or measured savings at those types of facilities.
Overseas Rollout and Customer Projects
The next developments to watch are announcements naming target countries, sales start dates and local partners, along with details of customer installations. Those disclosures would clarify how quickly ETI-W becomes available outside Japan and which industries adopt it first.
For prospective buyers, project-specific information will matter: available waste heat, hot-water demand, integration with existing equipment and performance under local operating conditions. MHI says it will tailor solutions to customers, but the source material gives no schedule for individual projects or further product-performance data.
Key Questions
What has Mitsubishi Heavy Industries announced?
MHI is expanding overseas sales of its ETI-W high-temperature centrifugal heat pump, which has been available in Japan since 2025.
What does the ETI-W heat pump do?
It is designed to recover low-temperature waste heat from factory processes and other sources, then produce hot water at temperatures up to 90°C.
What is the unit’s stated capacity and reported efficiency?
Cooling Post reports a maximum heating capacity of 640 kW and a COP of 4.01 during heating while supplying hot water up to 90°C. The source does not provide the test conditions for that COP result.
Which overseas markets will receive ETI-W?
The source material does not name specific countries or give a rollout schedule. MHI’s stated target applications include factories in several industrial sectors, along with commercial and accommodation facilities.
Has MHI confirmed customer installations or energy savings?
No. The supplied report describes intended applications and reported product performance, but does not confirm overseas installations, orders or measured energy savings.
