ADI CD Boiler – Technical Manual

1. INTRODUCTION
The global trend, European and international, aims at improving energy efficiency both in buildings and generators,
in order to reduce pollutant emissions in the atmosphere (SAVE directive, KYOTO agreement).
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 HEATING, BY HITECSA, 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 CD boiler.
The main characteristics of the
ADI CD
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.), in accordance with anti-legionella regulations.
-
EEC Approval by CERTIGAZ, high energy efficiency (according to the European directive 92/42/EEC).
-
Seasonal Efficiency up to 108% ref. to L.C.V.
-
Boiler agrees with the ErP (Energy related Products) Ecodesign Directive.
-
Boiler certified as “Low temperature”: flow temperature up to 90ºC, no limit of return temperature.
-
Boiler heat exchanger in stainless steel.
-
Power outputs from 70,4 to 904 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 23% of power (depending on the installation conditions and
models).
-
Burner power modulation by varying the premix air-gas flow by means of a variable speed motor fan.
-
Reduced electric consumptions per year thanks to a variable speed motor fan 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 Management System (B.M.S.).

It can be connected to telecomputing.
-
Reduced dimensions and weight:
Boiler heat exchanger ADI CD 450 (440 kW of output)
 Large: 81 cm, Long: 94 cm, Weight: 460 kg.
Easy installation in boilers rooms of difficult access.
Installation in terraces (reinforcement of the structure is not required).
Space saving in boilers rooms (440 kW in less than 0.76 m
2
).
