Benefits
Pasteurization is essential for product quality and food safety – but traditional systems rely on fossil fuels to generate heat, and electrical chillers to cool products. To improve the efficiency of your heating and cooling processes, we’ve developed an integrated heat pump system that reuses and upgrades excess heat and simultaneously generates heating and cooling, so you can:
- Lower your long-term operational costs1 by reducing energy inputs required for pasteurization
- Reduce CO2 emissions2 to meet climate targets, comply with emission caps, avoid fees and qualify for incentives
- Improve business resilience with less reliance on external utilities and less exposure to volatile fuel prices
Applications: Pasteurizers
How it works: recover and upgrade heat to power your process
The innovative system applies a heat pump’s ability to recover and upgrade heat to higher temperatures with a four-staged thermodynamic cycle: evaporation, compression, condensation and expansion. A refrigerant absorbs heat and evaporates into a vapour state; the compressor increases the pressure and temperature of the refrigerant; the refrigerant condensates to a liquid, rejecting usable process heat in the condenser to the heat sink. Through expansion, the refrigerant returns to its original state and the cycle starts over. Heat pumps can also recover energy from low temperature heat sources such as tower water and even generate ice water for cooling and heat simultaneously.
How much can you save?
By selecting the right heat pump and components and optimising pasteurizer configurations to your application, we help you maximise savings without compromising product quality, safety, or production performance. A typical dairy production in France, for example, could reduce energy consumption for pasteurization by up to 77%, saving up to €260,000/year on OPEX and reducing CO2 emissions by up to 650 tonnes/year3. A typical beverage producer in Spain, could reduce energy consumption for apple juice pasteurization by up to 68%, saving up to €153,000/year on OPEX and reducing CO₂ emissions by up to 1,165 tonnes/year4.
Rely on seamless integration and optimised design
With a full portfolio of heat pumps and components adaptable to local refrigerant regulations and energy infrastructure – and a deep understanding of your process – we design a heat pump system that is optimised to your pasteurizer and application. You can quickly adopt and easily scale the system across your factories and lines thanks to standard, reusable design. We also help you identify grants and subsidies in your market and provide support and calculations for your application process. Rely on seamless integration, design optimised for your processes, guaranteed performance and support tailored to your needs with our food and beverage expertise.
1. Actual energy savings in pasteurization process will vary based on several specific conditions in your market, including the relationship between electricity costs and fossil fuel costs as well as taxes or fees related to greenhouse gas emissions.
