METROPOLIS DGT

The small from the great performances

The Metropolis DGT is Simes very latest compactwall hung gas boiler for central heating and theD.H.W. production, ideal for whom looks and greatperformances but in a small space are important. In particular, the compact dimensions allow easyfitting into kitchen furniture, as well as easymaintenance in the narrowest spaces.

The high technical specifications, the elegantdesign and the facility of use assure the best ofSimes quality for the modern installations. Metropolis DGT comply with the EuropeanDirectives Gas EEC 90/396, ElectromagneticCompatibility 2004/108/CE, Low Tension2006/95/CE and Efficiency EEC 92/42.

The compact dimensions of Metropolis DGT(depth reduced of 5 cm compared to the previousmodel) mean it can easily fit into a kitchencupboard and be serviced even in restricted spaces.Bithermal heat exchanger definitely reduces thedeposits on sanitary equipment, removes unreliablecritical components (spiral heat exchanger andswitch valve) and allows an easy layout in the boiler.Moreover, it helps the access and guarantees asimple maintainability.The flowmeter on the sanitary side allows tomaintain the temperature.

Metropolis DGT is a high performance boiler.It comes equipped with an automatic pilotlight ionisation ignition, electronic circuitboard to continuously vary the heating andproduction of hot water, and anti-freezesystem which activates at 6C via an NTCsensor. If coupled with the external probe, it can adjust thetemperature, reducing the working costs of theheating plant.

All versions, equipped with a special kit, perfectlymatch a heating system with solar arrays.The solar kit is composed by a thermostatic mixervalve and by a temperature controller probe NTC. Itcompares the sanitary water temperature comingfrom solar storage, with the one laid on the sanitarypotentiometer.The boiler starts only if the temperature of the solarboiler is lower than the temperature laid in theboiler.

Metropolis DGT control board is both functionaland technological. For the first time, Sime adoptscapacitive keys, that is to say, electric devices, able torecognize a nearby finger.Moving mechanical parts are so removed and the

panel is watertight (the boiler has actually reachedthe protection level IPX5D). Easy and intuitivecontrols really simplify the usage, the LCD displayand coloured leds immediately show the maininformation and possible working defects.
