As cities and businesses across North America strive to become more sustainable, the focus is increasingly on the energy efficiency of commercial building spaces. Urban centers face mounting pressure to reduce carbon emissions, lower energy consumption, and integrate renewable energy sources into their infrastructures.
Heat pumps offer a key solution to these challenges. They efficiently transfer heat from a source, such as air or water, to provide heating or cooling for buildings. This process reduces the strain on traditional heating and cooling systems, such as chillers and boilers, which often consume significant amounts of energy. Heat pumps are often combined with electric boilers or other solutions such as thermal energy storage.
Alfa Laval's cutting-edge plate heat exchangers for heat pumps are at the forefront of this transformation, helping cities and commercial buildings achieve their sustainability goals.
Unleashing the power of heat pumps for businesses
Heat pumps play a crucial role in maximizing energy efficiency by transferring heat to or from sources such as air and water. By pulling heat from or rejecting heat into these reservoirs, heat pumps reduce the load on energy-intensive chillers and fossil-fuel-dependent boilers, enabling businesses to lower overall energy consumption and minimize greenhouse gas emissions. A key component of heat pumps is the plate heat exchanger, which efficiently transfers heat between fluids, optimizing the system's performance and energy use.
In urban areas, a significant amount of energy is lost as waste heat from buildings, transportation and industrial activities. Heat pumps equipped with plate heat exchangers can capture and repurpose this thermal energy, reducing energy usage and costs. Businesses often combine heat pumps with electric boilers or integrate them with other solutions, such as thermal energy storage, to further enhance energy efficiency.
Incorporating heat pumps with plate heat exchangers into energy systems can achieve operational efficiency and support environmental goals. This approach reduces reliance on fossil fuels, lowers greenhouse gas emissions and contributes to overall sustainability goals.

Alfa Laval’s heat pump technology: Leading the way in efficiency
To achieve maximum efficiency and extend the longevity of a heat pump, it’s critical to select the right technology and partner. Alfa Laval offers a range of plate heat exchangers designed specifically for these applications, each with unique features contributing to the system's overall performance and environmental impact.
- Semi-welded Plate Heat Exchangers are a prime choice for industrial heat pump applications, particularly those using ammonia or carbon dioxide as a refrigerant. With design pressures up to 900 psi, these exchangers are designed to reduce the ammonia charge and minimize the risk of leakage, thanks to Alfa Laval’s proven RefTight™ sealing system. They are also available with corrosion-resistant materials, making them ideal for recovering sea or river water heat.
- Brazed Plate Heat Exchangers are compact and efficient, ideal for use in both commercial and residential heat pump systems. They are compatible with most environmentally friendly, low-GWP refrigerants, including natural options like CO2 and hydrocarbons. This versatility makes them a standard solution for evaporating and condensing processes in heat pumps.
- Fusion Bonded AlfaNova Heat Exchangers offer a unique solution. Constructed entirely from stainless steel, these exchangers are resistant to the negative reactions that can occur between ammonia and copper. AlfaNova exchangers are compact and efficient, making them suitable for cooling sensitive liquids while taking advantage of ammonia’s low-GWP potential.
Need a heat exchanger that can withstand extreme pressure? The Alfa Laval AXP is specifically engineered for subcritical and transcritical applications using CO2 (R744) as a refrigerant. It also supports other fluids that require very high pressures.
Alfa Laval’s heat exchanger technology also includes advanced design features, such as subcooling integration and state-of-the-art sealing systems. These elements ensure that the systems optimize performance while minimizing their environmental impact, supporting the broader goal of creating sustainable cities.
