Advantages
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.
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.
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.
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.
Prefabricated thermal plants, fully assembled and factory-tested, combining absorption heat pumps, chillers and condensing boilers in a single hydraulic and electrical package.
Configurable solutions for heating, cooling, DHW, industrial processes, hybrid systems and large centralised installations.

The manufacturer
Founded in Italy in 1956, ROBUR is one of the leading international manufacturers of gas absorption heat pumps, absorption chillers and high-efficiency condensing boilers. With nearly seven decades of experience, the company has devoted itself to developing technologies that combine energy efficiency, renewable energy use and sustainability for heating, cooling and domestic hot water applications.
Its division specialising in gas absorption technologies offers one of the most complete ranges on the market, with air-source, ground-source and water-source heat pumps, reversible heat pumps, gas-fired absorption chillers and condensing boilers, as well as the modular LINK solutions, designed to simplify centralised installations and maximise energy efficiency.
Continuous investment in research and development, the use of natural refrigerants such as ammonia (R717) and the constant evolution of its technologies have made Robur one of the leading international benchmarks in efficient HVAC. Its solutions significantly reduce electricity consumption, make the most of renewable energy and help decarbonise buildings and industrial facilities.
Robur units are found in thousands of installations around the world, providing reliable, high-performance solutions for commercial buildings, industry, hotels, hospitals, sports facilities, public buildings and energy refurbishment projects, where efficiency, reliability and sustainability are key.
