Johnson Controls has launched the Frick HeatPAC, a factory-assembled ammonia heat pump designed to recover heat from refrigeration systems at food and beverage facilities. The company says it can deliver hot water at 54°C to 88°C and, in a modelled cheese-production case, cut annual energy costs by up to 40% versus natural gas boilers; actual results depend on site conditions and assumptions.
Johnson Controls has announced the Frick HeatPAC, a packaged reciprocating ammonia heat pump intended for food and beverage processing facilities. It is designed to recover waste heat from ammonia refrigeration systems and use it to produce high-temperature hot water for processes such as pasteurisation, sanitation and space heating.
The HeatPAC has a stated heating capacity range of 200 kW to 2,000 kW and is designed to supply water at temperatures from 54°C to 88°C (130°F to 190°F). Johnson Controls describes it as a pre-engineered, factory-assembled and pre-tested package, rather than a system engineered from scratch for each customer. The company says this standardised approach can reduce upfront investment and shorten lead times by weeks compared with engineered-to-order industrial heat pumps.
The package is the first Frick product engineered around a Mark 5 Sabroe reciprocating compressor platform. Listed equipment includes a welded plate-and-shell condenser with an integrated desuperheater, two-stage oil separation, a crankcase ventilation system and a variable-frequency drive with a standard 4:1 turndown. The reported ammonia charge can be as low as 40 kg (87 lb).
Each unit includes a Frick Quantum HD controller with Unity architecture. Its 15-inch touchscreen is configured for the application and, according to Johnson Controls, can integrate with other refrigeration equipment and a range of plant control systems. The company also points to its Frick Coolware selection software, which uses customer-entered application parameters to estimate heat demand, output, efficiency and potential operating costs.
Recovering Heat at Food Plants
The product targets a recurring energy mismatch in food manufacturing: refrigeration removes heat from one part of a facility while other processes require hot water or space heating. A heat pump that transfers recovered heat between those needs could reduce the amount of fuel or electricity required to generate process heat separately. The possible benefit is particularly relevant where facilities already operate ammonia refrigeration systems and have a suitable, steady demand for hot water.
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 a named operating installation. The economic and energy impact at any site will depend on factors such as the refrigeration system, temperatures required, operating hours, energy prices and the amount of usable waste heat available.

HeatPAC Design and Performance Estimates
HeatPAC is presented as a way to connect existing ammonia refrigeration equipment with a facility’s heat requirements, rather than as a replacement for refrigeration. Its packaged format is intended to simplify project selection and installation planning. The source report does not provide installation details, customer deployments or independent testing results.
For an example, Johnson Controls used Coolware to model a cheese producer needing 2,000 kW of hot water at 60°C. The company says the model projected annual energy-cost reductions of up to 40% compared with natural gas boilers. That figure reflects the energy-price and operating assumptions entered into the software; it is not a guarantee of savings for other plants or a measured outcome from an installed HeatPAC unit.
Site Results Still Need Verification
The announcement and source report do not identify a customer installation, provide field performance data or state when the first units will be delivered. It is also unclear how the product’s performance varies across different plant layouts, refrigeration loads and hot-water temperature requirements. The seven-times efficiency claim and the modelled cost reduction are presented by Johnson Controls, with the latter tied to assumptions entered in its software; neither figure is established here as a universal or independently measured result.
The source material also does not give pricing, installation costs, warranty details or the precise lead-time reduction customers can expect. Those details matter when comparing the packaged equipment with a boiler or a site-specific heat pump project.
Customer Projects Will Test the Claims
Prospective buyers can use Johnson Controls’ Coolware software to enter plant-specific operating parameters and request estimates of heat availability, output, efficiency and operating costs. The company has not named a first customer or set out a deployment schedule in the report. Further information about availability, pricing and project timing has not been provided.
The clearest next evidence will come from installations that show how much heat the units recover under actual operating conditions and how those results compare with the assumptions used in the estimates. Until such data are available, manufacturers will need to assess the equipment against their own refrigeration loads, process temperatures, energy prices and project costs.
Key Questions
What is the Frick HeatPAC?
It is a packaged reciprocating ammonia heat pump from Johnson Controls, designed to recover heat from ammonia refrigeration systems and supply hot water for industrial processes and facility heating.
What capacity and water temperatures does it support?
Johnson Controls lists a heating capacity of 200 kW to 2,000 kW and hot-water temperatures from 54°C to 88°C (130°F to 190°F).
How much could a facility save?
The company says the system can be up to seven times more energy efficient than a natural gas boiler in typical applications. Its modelled cheese-producer example projected annual energy-cost reductions of up to 40% against gas boilers. Those figures depend on application and modelling assumptions and are not guaranteed results.
Is the system already operating at customer sites?
The source report does not identify customer installations or provide measured field results. Availability dates and a first deployment have not been specified there.
