The Sabroe HeatPAC is an extremely compact, single-stage ammonia heat pump that recovers low-temperature waste heat and converts it into hot water up to 90°C. Built by Johnson Controls, it is a factory-assembled, pre-tested unit that utilizes a high-pressure reciprocating compressor to deliver exceptional energy efficiency with a very small refrigerant charge.
The HeatPAC system is engineered to provide a high coefficient of performance (COP) in a footprint significantly smaller than traditional two-stage heat pump designs. [

- Core Components:
- Compressor: Features ultra-reliable Sabroe HPO, HPC, or HPX high-pressure reciprocating compressors that can achieve differential pressures up to 40 bar and design pressures up to 60 bar.
- Heat Exchangers: Uses a unique integrated design combining a desuperheater, condenser, and subcooler to maximize thermal efficiency.
- Control System: Equipped with a UniSAB III system controller and a Variable-Speed Drive (VSD) as standard to optimize part-load performance.
- Operating Efficiency:
- Refrigerant: Uses natural ammonia (R717), which is environmentally friendly and highly efficient.
- Waste Heat Recovery: Ideal for turning waste energy from equipment like condensers or gas coolers into valuable hot water for industrial processes.
- Applications:
- Widely used in high-demand industrial sectors such as dairies, breweries, abattoirs, and district heating schemes.
- Perfect for processes requiring high-temperature hot water for sterilization and pasteurization. [1, 2, 3, 4, 5, 6, 7, 8, 9]
