Components for renewable energy systems

The air vent valves and deaerators ensure systems operate with water that does not contain any air. They are therefore capable of absorbing – and then eliminating – bubbles and micro-bubbles of air nestled in the critical zones of the system.

Circulation units are used on the primary circuit of solar thermal systems to control the temperature in the hot water storage.

The direct heat meter is suited to measuring heat consumption in residential buildings and is capable of metering the energy used in both heating and cooling modes.

Constructed to withstand temperature conditions and a high percentage of glycol, these valves are used for the balancing and management of the medium in solar thermal systems.

The thermostatic diverter valve is used in solar thermal systems that produce hot water for domestic purposes. Its function is to divert the water coming from the solar water storage to the users or to a storage system for integration according to the set temperature. This particular series of diverter valves can work continuously with hot water supplied at high temperatures from the solar water storage tank.

These safety relief valves ensure excessive heating capacity is discharged if the temperature of the medium exceeds the set point and are essential in biomass systems.

The thermostatic mixing valve is used in solar thermal systems that produce hot water for domestic purposes. It is designed to maintain the preset temperature of the mixed water delivered to the user outlet, when there are variations in the temperature and pressure of the hot and cold water at the inlet, or in the drawn-off flow rate.

The solar storage-to-boiler connection kits automatically control and optimise the thermal energy contained in the solar water storage, ensuring that domestic hot water is distributed throughout the system at a controlled optimum temperature.

CALEFFI GEO® series manifolds are used to control and distribute the medium in closed circuit geothermal systems.

This family of products is used to manage the main operating parameters for biomass systems, to guarantee their efficiency and safety.
