ATLANTIC BOILERS was formed in 1980, from a family

boiler business first established back in 1923, to promote

highly efficient boilerplant and to supply the first

commercial gas condensing boilers in the United Kingdom

in 1982. All editions of those boilers are running today

and, since 1982, ATLANTIC BOILERS has consistently

provided high grade condensing boilers based on smooth

austenitic stainless steel.

ATLANTIC BOILERS now introduce the latest compact,

entirely stainless steel condensing boiler, the M SERIES,

which is long-lasting and highly efficient at heat transfer

The M SERIES joins the earlier E series range of stainless

steel condensing boilers supplied successfully over twenty

years to Universities, Hotels, Hospitals, Social Care

Buildings, Leisure Centres, Offices and many other

buildings.

ATLANTIC BOILERS provides back-up commissioning,

servicing and spares through leading merchants across

the United Kingdom.

The ATLANTIC M-Series Condensing Boiler has a patentedunique fully pre-mix burner with fail-safe ionisation flamesensor. Filtered air is drawn from the boiler room, which thenpasses through a Venturi where it mixes with the natural gassupply before passing through a variable speed centrifugalfan. The air/natural gas mix then passes vertically down acircumferential series of burner tubes where it is ignited to givea circular ‘carpet’ of flame running evenly from top to bottomof the combustion chamber. The air/natural gas volume and,therefore, the heat output can be modulated from 100% downto 25%.

Alongside the vertical burner tubes are a set of smoothaustenitic stainless steel water tubes where circulation of waterfrom the building heating system cools the burner combustionto improve the low NOx performance.

The ATLANTIC M-Series Condensing Boiler has two distinctheat exchangers surrounding the combustion chamber. Bothare manufactured from high grade smoothaustenitic stainless steel tubes surrounded byturbulator sections designed to ensure maximumheat transfer. The hot combustion gases from thevertical burner tubes pass horizontally across thechamber where they transfer high temperatureheat to the first inner circumference of smallertubes as the gases pass through them. The cooledgases then pass through the second outercircumference of larger tubes where the remaining‘dry’ and ‘wet – condensing’ heat is transferred.

FlueARRANGEMENTSThe ATLANTIC M Series boiler flue requirements are economic – oftencutting the material and labour costs when compared to other boilers.As the flue gas exit temperature is always low, the volume of gases isalways greatly reduced throughout the year.

When the comparatively smaller flues are manufactured from highgrade plastics, installations are fitted easily and have up to 20 yearguarantees. Care should be taken when joining multiples of boilersinto one stack to ensure the boiler flue gases are injected togetherrather than interrupting through-put.
