    What Are Air Source Heat Pumps?

    Refrigeration-based Heat Transfer

    Air source heat pumps function using refrigeration-based heat transfer, similar to air-cooled packaged chillers commonly used in commercial and industrial settings. These systems extract heat from the external atmosphere, converting it into high-grade heating for buildings, manufacturing processes, and production applications. Even in cold climates, air source heat pumps remain highly efficient. Since absolute zero is -273°C, the air always contains usable heat energy, making these systems a practical and effective solution for year-round heating, even in low external temperatures. Pure Thermal’s advanced air source heat pump technology ensures consistent performance, reduced operating costs, and significant carbon savings.

    High-Performance Air Source Heat Pumps

    Pure Thermal’s air source heat pumps are available on a supply, commission, and maintenance basis, ensuring a seamless transition to low-carbon heating solutions. Their range includes low global warming potential (sub-650 GWP) refrigerants, meeting the latest environmental and regulatory requirements. With output temperatures from 35°C to 120°C, these systems are designed for high-performance heating across a range of industrial, commercial, and process applications. Additionally, they offer dual- or multiple-source configurations, allowing businesses to integrate air source heat pumps with cooling or waste heat recovery systems, further enhancing efficiency.

    Flexible System Configurations for Maximum Efficiency

    To meet diverse application requirements, Pure Thermal’s air source heat pumps are available in single-stage (Monobloc) and two-stage system configurations.

    The Monobloc Pure Thermal Commercial Air Source Heat Pump can achieve an output temperature of 80°C from an external ambient of -5°C, making it a reliable and efficient solution for medium-capacity applications. This removes the need for cascade or two-stage systems, simplifying installation while maintaining high efficiency.

    For large-scale projects, the Pure Thermal PLUS SO System offers a two-stage air source heat pump solution with single-system control and operation. This system integrates both an air source heat pump and a water-to-water heat pump, creating a high-capacity, next-generation heating system with enhanced thermal efficiency for industrial and commercial applications.

    Dual-Source and Multi-Source Heat Pump Technology

    Pure Thermal’s industrial air source heat pumps can be configured as dual- or multiple-source systems, improving operational efficiency by utilising additional heat sources. For example, where waste heat is available, the unit can integrate with chilled water return lines, cooling processes, or extract air systems. In scenarios where a 14°C flow from a cooling process is available, the heat pump can prioritise this source over lower-temperature external air, increasing efficiency and reducing electricity consumption.

    By allowing flexible heat sourcing, these systems provide greater efficiency and lower energy costs, ensuring sustainable heating solutions for a wide range of industries.

    Ultra-Low Noise Operation & F-Gas Phase-Out Readiness

    Pure Thermal’s air source heat pumps are designed for quiet operation, ensuring they meet strict noise level requirements. With a standard sound power level of 75dB(A), these units are suitable for urban environments, hotels, healthcare settings, and commercial buildings where noise control is a priority.

    Additionally, these heat pumps are F-Gas phase-out ready, ensuring compliance with evolving environmental regulations. By using low-GWP refrigerants and natural options like CO₂ and hydrocarbons, Pure Thermal ensures future-proof solutions that align with sustainability goals.

    Benefits of Air Source Heat Pumps

    Air source heat pumps offer a high-efficiency alternative to conventional fossil fuel heating systems, significantly reducing carbon emissions and operational costs. Pure Thermal’s advanced air source technology provides reliable performance in all climates, maintaining consistent output temperatures even in sub-zero conditions.
