ECOVAPOR

is a system certified as assembly under

PED Directive 2014/68/EU

allowing its operation without continuous supervision

of an authorised operator in compliance with the provisions in force in the country of installation up to 24 hours for

ECOVAPOR

or up to 72 hours for

ECOVAPOR 72

The generator supplied (CE certified by the Notified Body as a whole assembly in compliance with the

European Directive 2014/68/

EU)

consists of an equipment set, assembled and electrically and hydraulically factory tested at

ICI CALDAIE S.p.A

This system, supplied as an alternative to the standard low level probes, is designed to ensure that the water level in the generator
does not fall below the allowed value. It consists of two independent "fail safe" probes connected to two separated electronic
level relays with self-checking feature, capable of indicating:

–

the lack of water below the set level
