Industrial heat pump suppliers: temperatures and process integration

Industrial heat pump suppliers should be selected against the heat source and the process that will receive the heat. A maximum outlet temperature alone cannot establish suitability: source availability, temperature lift, heat duty, refrigerant, delivery medium and operating hours all matter. The six manufacturers below provide a non-exhaustive starting point, verified on 29 September 2026. Their product descriptions establish areas of activity, while a procurement decision requires a performance offer and acceptance conditions for the actual installation.

What information should a plant establish before contacting suppliers?

Begin with measured heat-source and heat-demand profiles. Identify the source fluid, inlet and outlet temperatures, flow variation and contamination. Define the required delivery temperature, return temperature, pressure and heat rate at the process connection. Hot water, a thermal-fluid circuit and steam are different duties. A process described as requiring 150°C may need that temperature at a heat exchanger surface, in a product stream or at a steam header; the distinction changes the equipment specification.

The IEA Heat Pumping Technologies Annex 58 report examines technologies supplying heat above 100°C, including working fluids and components. This category is useful for research, but it is not a universal product specification. Establish the temperature lift between the available source and required sink, then ask for the operating envelope and efficiency map. A catalogue value measured at a favourable condition should not become the annual energy forecast.

Which manufacturers provide a useful starting point?

GEA offers standard and customised industrial heat pumps, including ammonia screw-compressor equipment and systems connected to refrigeration plants. Its portfolio is relevant where process cooling and heating can be considered together. The overview describes applications around hot-water production and heat recovery; it does not establish that every GEA model can serve every steam requirement. Ask which named model, compressor arrangement and refrigerant meet the proposed temperatures, and who designs the process-side connections.

Johnson Controls' Sabroe HeatPAC is an ammonia-based reciprocating-compressor heat pump. The product page gives a 300–2,700 kW capacity range and hot water up to 90°C. Those are product-family descriptions, not simultaneous guaranteed conditions for a particular installation. This is a relevant enquiry for hot-water duties such as pasteurisation or cleaning, with a separate check on source conditions and part-load performance.

Mayekawa lists ammonia heat pumps and CO₂ heat-pump products, including hot-air heating. That variety matters for plants deciding whether useful heat should enter a water circuit or a drying-air stream. Request the specific product datasheet and source-to-sink balance rather than treating a refrigeration supplier's entire catalogue as interchangeable. Check local engineering and service coverage alongside the equipment's thermal capability.

Heaten's HeatBooster uses a piston-based compressor and addresses higher-temperature waste-heat recovery. Its current materials describe water delivery up to 200°C and steam configurations, with operating conditions varying by arrangement. The website uses differing steam-temperature descriptions, so a buyer should obtain a version-controlled specification rather than infer one universal steam limit. Published capabilities should be separated from a customer's accepted installation, operating history and guaranteed duty.

Everllence, formerly MAN Energy Solutions, provides large industrial heat-pump systems. Its industrial heat-pump material describes source options including industrial waste heat and water sources, and the ETES system. This is a relevant route for larger integrated projects. A district-heating reference can demonstrate machinery experience, but a factory needs its own assessment of delivery medium, pressure, production continuity and the interface with existing equipment.

Friotherm engineers, manufactures, installs and services heat pumps and chillers, with the Unitop centrifugal-compressor product family. Its scope includes industrial and district-energy applications. The useful procurement question is which configuration covers the plant's simultaneous heating and cooling conditions. Request a project-specific refrigerant declaration, capacity map and maintenance arrangement; the existence of a suitable compressor family does not by itself establish the complete system design.

How should refrigerants and integration affect the shortlist?

Require the refrigerant to be identified in each offer, together with charge, containment, ventilation, maintenance access and the site's applicable safety requirements. A generic description such as natural refrigerant does not answer installation questions. Ammonia, CO₂, hydrocarbons and other fluids create different engineering duties. Local permitting and competent engineering review should be incorporated into the project specification before a layout is frozen.

Examine source reliability as carefully as compressor reliability. Heat recovered from an intermittent production line may disappear precisely when another line needs heating. Dirty streams may need an intermediate exchanger, adding temperature differences, pumping and cleaning. Record who supplies that exchanger, the controls, electrical connection, civil works and backup heat. These interfaces often explain why a technically promising unit is difficult to integrate economically.

What evidence makes a quotation comparable?

Request useful heat delivered at the agreed boundary, electricity consumed by the complete system and performance over the expected load profile. The coefficient of performance relates useful heat output to electrical input, but its meaning depends on whether pumps and other auxiliaries are included. Agree how simultaneous cooling benefits are counted so that the same recovered energy is not credited twice in different budgets.

Acceptance should include minimum-load operation, start-up, transitions between production modes and loss of the heat source. Identify the meters and measurement uncertainty before testing. References should state the equipment configuration, source and delivery conditions, operating period and maintenance burden. A successful demonstration at another plant supports an enquiry; it does not remove the need to test the conditions that dominate this site's risk.

When should the technical assessment become an investment decision?

Translate the agreed performance map into annual operation using actual electricity tariffs, demand charges, fuel costs and production hours. Model the consequences of fouling, source interruptions and reduced demand. Avoid sizing solely for the brief annual peak if most operating hours occur far below it. The industrial heat-pump investment guide develops that financial boundary, while thermal storage addresses a different question: whether heat production and consumption should be separated in time.
