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, treaty of KYOTO).
Carbon dioxide (CO ) is one of the greenhouse gases that remain the longest in the atmosphere. In accordance
2
with IEO2007, predicted CO
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 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.
-
Seasonal efficiency up to 108%.
-
In compliance with the European Directive Ecodesign ErP (Energy related Products).
-
Boiler certified as "Condensing": flow temperature up to 90ºC, no limit of return temperature.
-
Boiler heat exchanger in stainless steel.
-
Power outputs from 70.5 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 30% of power (depending on the installation conditions and on
-
the boiler 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 the 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
Boiler control adaptable to all systems available on the market:
-
The boiler can operate by means of its own control.

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
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
emissions will be 33.9 billon tons in 2015 and 42.9 in 2030.
