Mitsubishi Heavy Industries is expanding overseas sales of its ETI-W centrifugal heat pump, already available in Japan since 2025. The system is designed to recover low-temperature waste heat and produce hot water up to 90°C; MHI reports a heating COP of 4.01 under that supply condition.
Mitsubishi Heavy Industries is expanding overseas sales of its ETI-W series centrifugal heat pump, a heat-recovery system designed to turn low-temperature waste heat into hot water at up to 90°C. The expansion brings the Japan-market product, available since 2025, to customers abroad, including industrial plants and commercial facilities that need process heat or hot water.
The ETI-W has a maximum heating capacity of 640 kW and uses HFO-1233zd(E) refrigerant, according to Cooling Post’s report on the company’s announcement. MHI describes the unit as a centrifugal heat pump intended to capture low-temperature heat left over from factory production processes and reuse it to produce higher-temperature water.
The company’s overseas sales focus is expected to include process applications in electronics, automotive, food, chemical and pharmaceutical factories. MHI also identifies heating and hot-water supply for commercial buildings and accommodation facilities as potential uses. The source does not specify which overseas markets will be served first or when sales will begin in individual countries.
MHI Thermal Systems says it will propose thermal systems based on each customer’s circumstances. In sites that already have chillers, ETI-W may be configured to recover heat carried in the chiller’s cooling water and reuse it as high-temperature water. For facilities such as data centres, the unit could use available heat to help meet heating and hot-water demand. These are described as possible applications, not confirmed installations.
Recovering Heat for Industrial Hot Water
The expansion puts a system designed for heat recovery at industrial temperatures in front of customers beyond Japan. For factories, some heat from production is discharged rather than reused; a heat pump can raise the temperature of a usable heat source so it can serve process or water-heating needs. Whether that makes sense at a particular site depends on its heat sources, temperature requirements, operating schedule and system design.
MHI reports that ETI-W achieved a heating COP of 4.01 while supplying hot water up to 90°C. COP is a measure of heat output relative to the energy input under stated operating conditions. The figure is a manufacturer-reported performance result; the source does not provide a test protocol, the full operating conditions or independent verification. It should not be treated as a guaranteed result for every installation.
For commercial operators and industrial energy managers, the relevant question is whether recovered heat can reliably meet a useful share of demand. Chiller heat recovery and data-centre heat reuse are among the potential arrangements MHI cites. The expansion signals an effort to sell the technology for such applications internationally, but the available report provides no customer orders, installed capacity overseas or projected energy savings.

From Japan Launch to Overseas Sales
MHI’s ETI-W was available in Japan from 2025, according to Cooling Post. The new development is the expansion of sales to overseas markets, rather than the announcement of a new model or a change to the unit’s stated capacity. A related Cooling Post report dated October 4, 2025, described MHI’s development of a centrifugal heat pump for the Japanese market that could supply hot water at 90°C.
The system’s stated role is distinct from a conventional chiller: it is presented as a way to recover low-temperature waste heat and deliver higher-temperature water. In a facility with a chiller, MHI says the heat retained in cooling water may be recovered for reuse. That approach could be relevant where cooling and heating needs coexist, though the report does not give details on required equipment, retrofit costs or site-specific performance.
The source identifies several sectors and building types as sales targets, but does not name distributors, specific countries or a timetable for the overseas rollout. It also does not say whether the company has secured overseas projects. Those details will determine how quickly the expansion translates into installations.
“It will offer thermal solutions according to the specific circumstances for each customer.”

Markets, Projects and Performance Details
The overseas sales announcement does not identify which countries will receive the product first, when it will be available in each market or how the company plans to distribute and service it abroad. No overseas customer names, orders or completed installations are cited in the source report.
Several technical and commercial details also remain unreported, including installation costs, required temperature and flow conditions, maintenance needs, operating limits and performance across different climates or load profiles. MHI’s COP figure is attributed as a reported result, but the source gives no test method or comparison baseline. The degree to which individual customers can reduce energy use or emissions cannot be established from the announcement alone.
The system’s proposed applications are possibilities, not evidence that every factory, data centre or commercial building can use it effectively. Suitability will depend on the site’s available waste heat and demand for hot water or process heat. The report does not quantify those requirements or describe project-specific assessments.

Overseas Availability and First Installations
The next developments to watch are the countries where MHI begins selling ETI-W, the timing of local availability and whether the company announces distributors or project partners. The source provides no schedule for those steps.
Further information from MHI on installation requirements, verified performance conditions and customer projects would help buyers judge the system’s fit. The first overseas deployments, if announced, could show how the heat pump performs in different industrial processes and building systems. Until those details are available, the confirmed development is the sales expansion itself and the product’s stated specifications and target applications.
