Advantages

Benefits of Robur technology

  • Making the most of renewable energy

    Robur absorption heat pumps capture renewable energy from the surroundings (air, ground or water), reducing primary energy consumption and the associated emissions, with electricity consumption practically limited to auxiliaries.

  • Very low electricity demand

    Because no electric compressors are used, the installation's electricity demand falls considerably, making it possible to reduce contracted capacity, minimise supply upgrades and lower running costs in refurbishments.

  • Natural refrigerants with minimal environmental impact

    Robur heat pumps and chillers use ammonia (R717) as a natural refrigerant, with virtually zero GWP and zero ODP, fully in line with the European F-Gas regulation.

  • Reliability and long service life

    Absorption technology uses very few moving mechanical parts. With no electric compressors, there is less wear, which supports high availability and a long service life.

  • Solutions tailored to each project

    Prefabricated thermal plants, fully assembled and factory-tested, combining absorption heat pumps, chillers and condensing boilers in a single hydraulic and electrical package.

  • Wide range of applications

    Configurable solutions for heating, cooling, DHW, industrial processes, hybrid systems and large centralised installations.
