    Robur Heat Pump Features

    Robur heat pumps are designed for high-performance heating and cooling, integrating advanced semi-hermetic reciprocating compressors to deliver efficient and reliable operation. These compressors ensure precise temperature control, making them ideal for residential and commercial applications that demand consistent performance.

    Using the natural refrigerant ammonia, Robur heat pumps provide a low environmental impact while maintaining exceptional efficiency. The system operates effectively in extreme conditions, with a minimum external air temperature of -20°C and the ability to produce water temperatures exceeding 65°C. This makes them suitable for applications requiring substantial heating capacity, including district heating and process industries.

    Equipped with axial fans, the heat pumps achieve optimal airflow and heat exchange, maximising efficiency even in demanding environments. Their gas-powered design functionality allows seamless integration within existing gas heating systems, enhancing versatility. By combining high efficiency, sustainability, and robust performance, Robur heat pumps offer a future-proof solution for modern temperature control requirements without the need for electrical system upgrades.

    Robur Heat Pumps Natural Refrigerant Systems

    Robur heat pumps utilise natural refrigerants to provide sustainable and efficient temperature control. These refrigerants offer low global warming potential (GWP), making them a future-proof solution as industries move away from high-GWP synthetic alternatives.

    Gas Absorption Heat Pumps deliver exceptional efficiency while operating at low pressures, extending system lifespan and reducing maintenance costs. Ammonia’s zero ozone depletion potential (ODP) and ultra-low GWP make it a preferred choice for businesses prioritising environmental sustainability.

    By integrating natural refrigerants, Robur heat pumps combine high performance, regulatory compliance, and long-term cost savings, supporting businesses in transitioning to eco-friendly heating and cooling solutions.
