Industrial heat pumps are becoming a practical source of process heat for factories seeking to reduce fossil-fuel use, recover waste heat and control long-term energy costs. Yet choosing a system is more complex than comparing heating capacity or maximum outlet temperature.
An industrial heat pump must work with the actual conditions of the plant. These include the available heat source, required process temperature, operating hours, seasonal ambient temperature and existing boiler or cooling system. A good manufacturer should therefore provide more than a standard machine. It should also help the buyer match the equipment to the process.
The following five industrial heat pump manufacturers represent different parts of the market, from modular air-source systems to large heat-recovery plants. The order is intended as a practical shortlist rather than a universal ranking.
A commercial heat pump usually serves space heating or domestic hot water. An industrial system may need to supply process water, support drying, recover heat from refrigeration, preheat boiler feedwater or produce higher-temperature water and steam.
The temperature printed on a product page is only one part of the decision. Buyers also need to consider the temperature lift. Raising water from 55°C to 90°C is very different from taking outdoor air at a sub-zero temperature and producing the same 90°C output.
The heat source is equally important. Depending on the project, an industrial heat pump may collect heat from ambient air, cooling water, wastewater, exhaust air or another production process. A stable, warm waste-heat source can often improve performance, while an air-source system may offer easier installation when no usable process heat is available.
This is why the most suitable industrial heat pump manufacturer depends on the project itself.
Manufacturer | Main industrial heat pump direction | Published temperature position | Suitable project types |
|---|---|---|---|
Leomon Technology | High-temperature air-source, CO₂, cascade and steam heat pumps | 75°C, 90°C and 120°C hot-water ranges; dedicated 150°C steam series | Process hot water, drying, cleaning, food processing, pharmaceuticals and factory heating |
GEA | Waste-heat recovery and industrial process heating | Up to 95°C for the RedGenium range | Food, beverage, dairy, refrigeration-linked plants and district heating |
MAN Energy Solutions | Large-scale industrial and district heat pump systems | 0–150°C supply range for MAN ETES | Major factories, utility-scale projects, heat networks and thermal storage |
Johnson Controls / Sabroe | Industrial refrigeration and high-temperature heat recovery | Up to 125°C for HitemHP | Food, dairy, pharmaceutical processes and indirect steam generation |
Mayekawa | Ammonia and CO₂ systems combining heating and cooling | Up to approximately 85°C in selected ammonia systems | Food plants, breweries, cold storage and facilities with simultaneous cooling and hot-water demand |
Leomon Technology develops industrial and commercial heat pumps for projects requiring process hot water, high-temperature heating, drying and steam generation. Founded in 2005, the company supplies air-source, CO₂ and high-temperature systems to customers in more than 50 countries and regions.
One reason Leomon stands out is the width of its temperature range. Its high-temperature air source heat pumps include product directions for 75°C, 90°C and 120°C output. This allows buyers to select a system according to the real process temperature instead of automatically moving to the highest-temperature model.
A factory may use a 75°C system for cleaning, hot-water preparation or lower-temperature drying. Higher-output systems can support processes that cannot be served by standard commercial heat pumps. Leomon also lists a dedicated 150°C steam heat pump range for industrial applications requiring steam rather than hot water.
For sites that need process hot water while also managing cooling demand, Leomon offers an industrial CO₂ heat pump. The published range includes heating capacities from approximately 59 to 155kW under stated operating conditions, with maximum outlet-water temperatures of 75°C in the technical table.
This type of system may be considered for parts cleaning, food processing, textile production, pharmaceutical plants and other facilities where heat recovery can replace part of the energy normally supplied by boilers.
Leomon is especially relevant to buyers looking for a Chinese high-temperature heat pump manufacturer with multiple product platforms and customization support. Its OEM and ODM service can cover project-specific capacities, control requirements, operating conditions and system configurations.
GEA is a major global supplier of food-processing, refrigeration and industrial energy equipment. Its heat pump experience is closely connected to refrigeration plants, making the company particularly relevant where cooling and heating need to work as one system.
The RedGenium series supplies hot water at temperatures of up to 95°C. It can recover heat from refrigeration systems, process water and other low-grade sources that might otherwise be released into the environment.
This approach can be useful in dairies, beverage plants, food factories and other facilities with continuous cooling demand. Instead of operating a refrigeration plant and boiler independently, the recovered heat can be upgraded and returned to production as usable hot water.
GEA is therefore a strong candidate for buyers planning an integrated refrigeration and heat-recovery project. Its systems are generally better suited to engineered industrial installations than to buyers seeking a simple packaged air-source unit.
MAN Energy Solutions operates at the larger end of the industrial heat pump market. Its MAN ETES technology is designed for large industrial sites, district heating networks and energy-storage projects, with a published supply-temperature range extending from 0°C to 150°C.
These systems can recover heat from industrial processes, cooling water, seawater or other sources and upgrade it for use in a heat network or production facility. The technology can also be combined with thermal storage when the timing of heat generation does not match the timing of demand.
MAN is most relevant when capacity is measured in megawatts rather than tens or hundreds of kilowatts. A project of this size normally requires detailed feasibility studies, civil engineering, site integration and long-term planning.
For buyers operating a single production line or a medium-sized factory, this scale may be greater than necessary. For heavy industry, large campuses, utilities and municipal heating networks, however, MAN is one of the industrial heat pump manufacturers worth evaluating.
Sabroe, part of Johnson Controls, has a long history in industrial refrigeration and heat recovery. Its heat pump portfolio is aimed at factories that need to reuse heat from refrigeration or another controlled source.
The HitemHP range can supply temperatures of up to 125°C and covers heating capacities from approximately 100 to 1,000kW. Potential applications include pasteurization, sterilization, cleaning, food production, pharmaceuticals and indirect steam generation.
Sabroe also offers industrial ammonia heat pumps designed to work with higher-temperature heat sources. These systems may suit plants where refrigeration equipment already operates for long hours and produces a steady supply of recoverable heat.
The main advantage is system integration. Rather than treating heating and refrigeration as separate utilities, the plant can use one process to support the other. Buyers should still assess refrigerant policy, machinery-room requirements, operator experience and local safety standards before selecting an ammonia or hydrocarbon-based solution.
Mayekawa is another established name in industrial refrigeration and thermal engineering. Its heat pump systems use natural refrigerants such as ammonia and CO₂ and are often installed in food processing, beverage production, cold storage and other refrigeration-intensive industries.
Selected Mayekawa ammonia heat pumps can provide hot water at temperatures of up to around 85°C. The company also offers CO₂ systems capable of supplying hot and cold water as part of the same process.
This combined approach is useful when a plant has simultaneous demand on both sides. A brewery, for example, may require refrigeration for production and storage while also needing hot water for cleaning or pasteurization. Recovering heat from the cooling process can reduce the amount of energy rejected outdoors and lower boiler demand.
Mayekawa is particularly relevant when natural refrigerants and refrigeration integration are central to the project.
The best supplier depends on how the heat pump will be used.
A factory that needs 75°C to 120°C process water without a convenient waste-heat source may start with an industrial air source heat pump. This arrangement can be easier to install because it collects energy from ambient air and does not depend on another production process running at the same time.
A plant with constant refrigeration, warm wastewater or process cooling should also examine waste-heat recovery. GEA, Sabroe and Mayekawa are strong in this area, especially when heating and cooling loads occur together.
Very large industrial sites and heat networks may need the project scale offered by MAN Energy Solutions. These projects are usually based on detailed system engineering rather than a standard product selection.
Leomon covers a useful position between these groups. Its product range can serve individual factories requiring packaged high-temperature air-source systems, CO₂ heat pumps, cascade configurations or industrial steam solutions. Buyers can review its wider range of industrial applications to see how different heat-pump configurations fit production processes.
A useful quotation starts with operating data. Simply asking for a “100kW industrial heat pump” is not enough because the same rated capacity can produce very different results under different conditions.
Information to provide | Why the manufacturer needs it |
|---|---|
Required water or steam temperature | Determines the appropriate heat-pump cycle and model |
Inlet and return-water temperature | Defines the true temperature lift |
Required heating capacity | Establishes unit size and number of modules |
Available heat source | Affects system design and expected performance |
Outdoor design temperature | Important for an industrial air-source heat pump |
Daily and annual operating hours | Helps estimate energy use and return on investment |
Existing boiler or chiller details | Shows whether the system will replace or support current equipment |
Electrical supply | Confirms voltage, frequency and installation requirements |
Required redundancy | Determines whether several modules should operate in parallel |
Site and control requirements | Helps plan installation, communication and plant integration |
Buyers should also request performance data at their intended operating conditions. A coefficient of performance measured at a low temperature lift should not be used to predict efficiency at a much higher outlet temperature.
Leomon’s product range gives buyers several possible routes rather than forcing every project into one configuration. The company can match lower-temperature hot-water demand with conventional industrial units, use high-temperature systems for more demanding production processes and offer dedicated equipment where steam is required.
Its published operating range also includes solutions intended for cold climates. However, final output and efficiency should always be checked at the project’s actual ambient temperature and required supply temperature.
Leomon combines product manufacturing with system selection, customization and export support. According to its company information, it operates two production bases, maintains TUV-certified testing laboratories and has supplied heat pumps to more than 50 countries and regions.
For an accurate proposal, buyers can contact Leomon with the required temperature, heating capacity, heat-source conditions, operating schedule and destination market. This gives the engineering team enough information to recommend a suitable industrial heat pump instead of quoting a model based only on nominal capacity.
Industrial heat pump manufacturers do not all serve the same type of project. GEA, Sabroe and Mayekawa bring strong experience in refrigeration-linked heat recovery. MAN Energy Solutions focuses on large industrial and district-scale systems. Leomon offers a broad selection of air-source, CO₂, high-temperature and steam heat pumps for factories seeking a more flexible product and customization route.
Before choosing a supplier, buyers should define the available heat source, required output temperature, heating load and operating schedule. These four factors will usually narrow the field more effectively than comparing brand size alone.
The right system should deliver the required heat under real operating conditions, integrate with existing equipment and remain practical to service throughout its working life.
Provide the required outlet temperature, inlet temperature, heating capacity, heat source, operating hours, ambient-temperature range, electrical supply and installation location.
It can in some applications. In others, the heat pump supplies the base load while an existing boiler covers peak demand or higher-temperature stages.
Air-source systems are often easier to install. Waste-heat systems can be more efficient when a stable heat source is available throughout the required heating period.
No. Buyers should also compare capacity and efficiency at the actual inlet temperature, outlet temperature, heat-source condition and ambient temperature.
Yes. Leomon provides OEM and ODM support for project-specific capacity, temperature, controls, configuration and market requirements.
