The Arcobaleno collectors by Emmeti, the practical and efficient heater/hot water solution in the public and private building industry, have now become equipped with new and even more functional differential regulators with microprocessors.

The range of products, recently completed with the innovative VP evacuated-tube collector - in addition to the well-consolidated N models, with black collection area surface, and the SX and SI models (built-in), with a blue selective surface - is used in closed-circuit solar energy systems for producing domestic hot water, heating swimming home pools or pre-heating and/or additional heating in room heating systems with extremely reduced pressure losses.

The new solar stations, available in various versions, are equipped with high-temperature safety and vent accessories that allow to complete the solar energy system in maximum efficiency as well as adapt it to the various local environments. The presence of two differential regulators allows the solar energy to be used for the heating system also.

Built in minute detail with highest-quality materials that guarantee the reliability and long life of the product, the Arcobaleno collectors are compliant with the standards UNI EN 12975-1 and UNI EN 12975-2 and are guaranteed for 5 (N model) to 10 years (SX, SI and VP models).
The thermal insulation furniture, for the N, SX and SI models, is in high-density mineral wool with a thickness of 50 mm.
The internal surface of the double-walled evacuated tube of the VP Arcobaleno collector has a selective coating in high-absorption aluminium nitrite. In addition, the parabolic shape of the CPC modern mirror further concentrates the sunlight and increases the system's efficiency.

It should also be noted that the innovative technology of the Emmeti systems allows to utilize the heat in an ideal manner even in unfavourable weather conditions, and the construction costs of a solar energy system represent an investment which is recovered in a surprisingly short time.
