5 GENERAL SPECIFICATIONS
ACK2 boilers are reverse flame, 2 pass, wet back, cylindrical shell type, hot
water, liquid or gas fired, B
23
steel boilers.
They are manufactured and tested in accordance with TS EN 303-1, by an
ISO 9001-2000 registered company.
They are economical and environmentally friendly.
Compact design ensures easy transport into boiler rooms.
The boilers have been specially designed and produced to perform efficient
combustion with both gas and liquid fuels.
Boiler gas side pressure loss is well below the limited values in EN standards.
Economic ad safe heating system operation through optional boiler control
panels. Control Panel in Three Different Models: a) Standard Single stage
boiler control panel b) Standard Two stage boiler control panel c) Weather
Compensated Economy Panel.
ACK2 boilers have 21 different capacities between 80.000-3.000.000 Kcal/h.
(93 – 3488 kW) and standard working pressure is 4 bar.
Minimum heat loss with perfect insulation.
Wide water galleries and the return water connection is from the back bottom
side provide excellent natural circulation and safe heat transfer.
No additional intermediate flow pieces required. All necessary connections are
already on the boiler.
They have low combustion chamber loading for clean combustion with low
nitrogen oxide emissions.
Boiler front door can be opened in both directions, very useful in boiler rooms
with limited space.
6 OPERATING PRINCIPLES
These boilers have been designed to heat hot water and must be connected
to a heating plant and/or a domestic hot water plant within the limits of its
performance and output.
ACK2 boilers are hot water boilers with a maximum outlet temperature of 90
°C (up to 105 optional) and a maximum allowable operation pressure of 4 bar
gauge (up to 8 bar gauge optional). Return water temperatures must not be
lower then 55 °C on oil and 60°C on gas firing .
These boilers are not suitable for use as a direct water heater. Where potable
or sanitary hot water is required, a matching indirect heat exchanger must be
provided in the system.
These boilers are suitable for Liquid (6 cSt at 20˚C oil) and gaseous (Natural
gas, Town gas, LPG) fuels. Please ask your seller for the details of the Local
suitable fuels which can be fired in ACK2 series boiler.
This boiler must be fired by a compatible burner (CE marked) certified to EN
76 (gas firing) or EN 267 (oil firing) to comply with the Boiler Efficiency
Directive 92/42/EEC.
This boiler is suitable for use in either open vented or pressurized expansion
vessel heating systems. The system must have a matching expansion system.
Second pass heat transfer combustion gas pipes have turbulators in order to
maximize heat transfer to water.
