Johnson Controls has launched the Frick HeatPAC, a packaged ammonia heat pump designed for food and beverage processing facilities. The company says it can recover heat from ammonia refrigeration systems to supply hot water, but its efficiency and cost claims depend on application and energy-price assumptions.
Johnson Controls has announced the Frick HeatPAC, a packaged ammonia heat pump for food and beverage facilities that captures waste heat from refrigeration systems and uses it to produce high-temperature hot water. The launch matters to processors seeking to reuse heat already generated on site for uses such as pasteurisation, sanitation and space heating, though performance and savings will vary with operating conditions.
The HeatPAC uses a reciprocating ammonia heat pump and is rated for heating capacities from 200 kW to 2,000 kW. Johnson Controls says it can provide hot water between 130°F and 190°F (54°C to 88°C). The system is intended to connect the heat rejected by an ammonia refrigeration plant with processes elsewhere in a facility that require heat.
The company describes the equipment as factory-assembled and pre-tested, with a standardised design intended to reduce the complexity of installation compared with engineered-to-order industrial heat pumps. Johnson Controls says this approach can reduce upfront investment and cut lead times by weeks; the source report does not provide independent cost or delivery comparisons.
Listed components include a welded plate-and-shell condenser with an integrated desuperheater, two-stage oil separation and a variable-frequency drive with a standard 4:1 turndown. The reported ammonia charge is as low as 87 pounds (40 kg). A Frick Quantum HD controller is designed to integrate with a range of plant control systems, and the company says the touchscreen can coordinate operation with other refrigeration equipment and support remote access.
Reusing Heat in Processing Plants
Food and beverage plants can have simultaneous demand for refrigeration and process heat. A heat pump that draws on refrigeration-system waste heat could reduce the need to generate some of that heat separately, potentially lowering fuel use and operating costs. The practical benefit depends on how much recoverable heat is available, the hot-water temperature and volume required, and the plant’s operating schedule.
Johnson Controls says HeatPAC can be up to seven times more energy efficient than a natural gas boiler for typical food and beverage applications. That is a company claim, not a reported result from an identified installation. The source gives no measured field data, test protocol or definition of the comparison boundary, so the figure should not be treated as a guaranteed saving for every site.

Packaged Design and Performance Estimates
The HeatPAC is described as the first Frick product built around a Mark 5 Sabroe reciprocating compressor platform. Its packaged format combines the compressor platform, heat-exchange equipment and controls rather than requiring a project-specific system design for each installation. Standardisation may simplify procurement, but the source report does not establish how the system will fit a particular plant or what modifications may be needed.
Johnson Controls also points customers to its Frick Coolware selection software. Users enter application details to estimate waste-heat requirements, heat output and efficiency, and to obtain performance ratings that can help estimate operating costs. The company’s example is a modelled cheese plant requiring 2,000 kW of hot water at 140°F (60°C): the software projects annual energy-cost reductions of up to 40% against natural gas boilers under the energy-price and operating assumptions entered. This is a modelled case, not a reported customer outcome.
Site Results Still Need Verification
The launch report does not identify a customer installation, provide measured operating results or state when commercial deliveries will begin. It is also unclear how much waste heat a facility must have available to reach the product’s rated output, or what installation work and integration costs a specific site would face.
The efficiency and savings figures depend on application and modelling assumptions. Johnson Controls does not provide the energy prices, boiler efficiency, operating hours or other inputs behind the cheese-producer example in the source material. The report also does not give independent testing or a full comparison of emissions. Prospective users would need site-specific engineering and cost estimates before treating the projections as likely results.
Site Assessments Will Shape Adoption
The next practical step for interested processors is to assess whether their refrigeration systems produce recoverable heat at the times and temperatures needed by their processes. Coolware can provide preliminary performance estimates, according to Johnson Controls, but those estimates would need to be checked against actual plant data and operating requirements.
Further details that could clarify the product’s commercial prospects include installation schedules, delivered-system pricing, measured performance at operating sites and the assumptions behind company savings comparisons. The launch announcement does not specify a timeline for those details or name an initial customer project.
Key Questions
What is the Frick HeatPAC?
It is a packaged ammonia heat pump from Johnson Controls, designed to recover waste heat from industrial ammonia refrigeration systems and provide hot water for food and beverage operations.
What capacity and water temperatures does it support?
Johnson Controls lists a heating capacity range of 200 kW to 2,000 kW and hot-water temperatures of 130°F to 190°F (54°C to 88°C).
Does the HeatPAC cut energy costs by 40%?
Not as a confirmed result for every facility. Johnson Controls reports a modelled cheese-producer example projecting up to 40% lower annual energy costs than natural gas boilers under the inputs entered into its software. The report does not provide measured customer results or all modelling assumptions.
How much ammonia does a unit contain?
The source report says the ammonia charge can be as low as 87 pounds (40 kg). It does not give a single charge amount for all configurations.
