1. INTRODUCTION
The global trend, European and international, aims at improving energetic efficiency both in buildings and
generators, in order to reduce pollutant emissions in the atmosphere (directive SAVE, treaty of KYOTO).
Carbon dioxide (CO
2
) is one of the greenhouse gases that remain the longest in the atmosphere. In accordance
with IEO2007, predicted CO
2
emissions will be 33.9 billon tons in 2015 and 42.9 in 2030.
This is why the European campaign known as “20-20-20 in 2020” has been created, with the aim, among
others, of cutting carbon dioxide emissions by 20% by 2020.
ADISA CALEFACCION, company specialized in the manufacturing of gas boilers with high efficiency
performances and reduced pollutant emissions (“clean combustion”), has developed an innovating and
revolutionary product contributing to a technological evolution in the field of water boilers for centralized
installations: the ADI LT boiler.
The main characteristics of the ADI LT boiler are:
- Maximum efficiency in every kind of installations at any working temperatures.
Renovation of installations with traditional heat radiators
New installations of very Low Temperature (heating floor, fan-coils, A.H.U., etc.).
Domestic Hot Water (D.H.W.S.), in accordance with anti-legionella regulations.
-
EEC Approval by AFNOR, with 3 performance stars for its high energetic efficiency (according to the
European directive 92/42/EEC). Nett efficiencies from 96% to 104% ref. to L.C.V.
-
Boiler certified as “Low temperature”: flow temperature up to 90ºC, no limit of return temperature.
-
Boiler heat exchanger in stainless steel.
-
Power outputs from 104 to 695 kW.
-
Maximum efficiency per year :
Variable temperature on boiler.
Boiler power modulation according to the demands of the installation.
High reduction of stop/start cycles.
Minimum heat losses due to convection/radiation through the boiler.
Inconsiderable heat losses through the chimney when the boiler is not operating.
-
Gas boilers with modulating burner starting from 30% of power (depending on the installation conditions and
models).
-
Burner power modulation by varying the premix air-gas flow by means of a motor fan of variable speed.
-
Reduced electric consumptions per year thanks to the motor fan of variable speed for the air-gas inlet.
-
Ecological combustion (“PREMIX” burner of innovative design).
NOx: about 10 ppm, CO: about 50 ppm (both referred to 3% O
2
).
-
Boiler regulation and control adaptable to all systems available on the market:
The boiler can operate by means of its own regulation.
It can be connected to a sequence control unit in an installation with several boilers.
It can be connected to Building Manage System (B.M.S.).
It can be connected to telecomputing.
-
Reduced dimensions and weight:
Boiler heat exchanger ADI LT 475 (464 kW of output)
Large: 81 cm, Long: 96 cm, Weight: 490 kg
Easy installation in boiler rooms of difficult access.
Installation in terraces (reinforcement of the structure is not required).
Space saving in boiler room (464 kW in less than 0,78 m
