The ATLANTIC R-Series year-roundmaximum condensing boiler hastwo distinct heat exchangers, thefirst of developed quality steeldesign and the second of highgrade plastic design.

The flue gases leave the first heatexchanger at temperatures below90˚C, and are then extractedfrom the second condensing heatexchanger at temperaturesalways below 50˚C. Theintroduction of combustion airthrough the condensingexchanger lowers the flue gastemperature below dew-point,hence there is no need for returnwater temperature to be low.

The boiler will condense to it'smaximum efficiency even at 82˚Cflow & 71˚C return. Forcombustion air, at inlettemperatures below 30˚C,efficiencies always exceed 92%.These conditions applythroughout the year in the UK.

The lower part of the condensingexchanger has a condensateneutralising section built in,eliminating the need for separateequipment in the future. TheATLANTIC R Series boilerpipework requirements are asstraight forward as aconventional boiler or a highefficiency boiler. No specialcircuits are required to createcondensing.

IN-BUILT FEATURESConstant temperaturerequirements are achieved withboiler controller, shunt pump, 4-port valve and flow sensor.

Minimum flow and minimumtemperature requirements areachieved with boiler controller,pump, 4-port valve and sensor.

Variable temperaturerequirements are achieved withboiler controller, shunt pump, 4-port valve, outside sensor andflow sensor.

All the above systems can beprovided by the boiler system.Alternatively, the ATLANTIC RSeries boiler(s) can be enabled bya BMS system and also can

provide alarm signals to a BMSsystem. The boiler(s) will continuetheir own in-house operationalcontrol ensuring correctcombustion and hydraulic function.

As a modulating burner option,the boiler controller system canbe modified on a 0-5 volt and 0-10 volt band to give variableheat output.

The boiler body is made of 3mm thickquality steel with a water-cooled combustionchamber. The burner fires horizontally throughthe combustion chamber and makes a seriesof passes through a horizontal heatexchanger. The steel boiler is externallycovered with an 80mm layer of rock woolthermal insulation. Access to the heatexchanger is through a panel at the front ofthe boiler secured by four bolts.

The condensing exchanger is made ofpolypropylene and contains a series ofsmooth polypropylene heat exchanger tubes.The bottom of the condensing exchanger hasa section containing limestone granules toneutralise the condensate.

The boiler has a pre-wired control panelincorporating an isolator switch with indicatorlamps, modulating, high/low or on/off burnercontrol, water flow sensor with indicatorlamps, a safety limit thermostat, hours runindicator, flue gas thermometer and aweather-controlled programme.

The boiler assembly includes a 4 way valve,a shunt pump, both pre-wired and operatedby the control panel, and a shunt pipearrangement with connections for a restrictedconstant temperature circuit.

The pressurised B100 or gas burner has;aluminium body, motorised fan air supply, oilor gas valve with controlled rate of opening,ignition transformer, air/B100 or air/gasmixing, combustion head, differential pressure

switch, control box with ionisation flameprotection, balanced flue pressure switchcontrols. Burners are available with pre-mix,modulating, high/low and on/off operationdepending on fuel type and model size.

The flue gas fan(s) in each boiler assemblycontain - aerodynamic polypropylenehousing, vibration free mountings, minimumpressure loss inlet & outlet, totally enclosedsynchronous motor, maintenance free, dust &water proof bearings, infinitely adjustable fanmotor speed regulator. The number of fansdepends on the boiler model. From themodel R22-15 to the model R22-90 the fan ismounted within the boiler casing. Frommodel R22-150 upwards, the multi-fanassembly is mounted to the rear of the boiler.

Each boiler has its own header with in-built 4-port valve and shunt pump. This guaranteesminimum water flow and temperature control. Single and group boilers can use abalancing & sedimentation vessel or a low velocity header as a neutral heat outlet. Anynumber of circuits, in order of priority, can then be served adequately from the boiler(s)

PIPEWORK ARRANGEMENTS

TYPICAL ONE BOILERARRANGEMENT One R22 boiler servesdomestic hot water (priority)and weather compensatedradiators. The fast-responseindirect cylinder always needsto receive primary hot waterwithin 1 or 2 minutes ofdemand so it receives priorityfrom the balancing vessel orheader. The radiators have aresponse time of about 20minutes so they take primaryheat as a second function.Consequently the indirectcylinder is served first from thebalancing vessel.

MULTIPLE BOILER ARRANGEMENT This might be a typical medical centre situation where duty and standby boilerplant serves sanitary hot water, air conditioning and underfloor space heating.The ultra-fast response plate heat exchangers need primary heating within afew seconds, the air conditioning (in mid-winter) needs primary  heating withina few minutes, whereas the underfloor space heating has a much longerresponse time. The plate heat exchangers are served first from the balancingvessel, the air conditioning second and the under-floor heating last.

CONDENSING FLUE ARRANGEMENT

The ATLANTIC R Series boilerscan have either conventionalor balanced flues for dieseloil, kerosene, natural gas orLPG. The boiler fluerequirements are economic –often cutting the costs ofmaterial and labour whencompared to other boilers. Asthe flue gas exit temperature isalways low, the volume ofgases is always greatlyreduced throughout the year.

In addition, the ATLANTIC R Series boilers have variable speed flue gas extract fans which permitextensive vertical and horizontal flue ducts in carefully chosen TECHNAFLON condensing flues. The fluesare graded to the boiler(s) to allow the condensate to drain to the tank in the base of each boiler. Thecondensate is then treated using limestone marbles before flowing out to a normal drain.

TECHNAFLON condensing flues are precision-made from polyvinylidene fluoride (PVDF) which isextremely corrosion-resistant, hard wearing and not effected by ultra-violet radiation. The flues areinstalled without insulation. The flue gases cool rapidly, releasing the heat to the building and increasingthe plant efficiency.

Chilham Castle, Kent

BALANCING AND SEDIMENTATION VESSEL

The balancing vessel is located close to the boilers, with its feet placedon a base to allow the boiler flows and returns to normally vent to thevessel. One full size cold feed pipe should be taken to the connection’P’ on the vessel and fitted with a ‘normally open’ ball valve, allowingunrestricted heating system expansion and contraction to take placealong the pipe.

The different flow pipes of separate heating circuits should beconnected progressively down the header from the top flow 'A'. Thereturns should be connected similarly upwards from the bottom return'I'. DHW priority flow and return circuits should be taken from and tothe high level ‘W’ tappings.

When connections are complete and the system is ready for filling.Firstly everything should be isolated from the vessel. This includes theboilers (with their shunt pumps) connected to ‘L’ (flow) and ‘M’(return)and the heating circuits - 'A' and 'I'. - which should be isolated fromthe vessel. The vessel air vent ‘V’ and drain/sludge valve ‘D’ shouldbe closed.

The different heating circuits should then be filled separately. As thecircuits are progressively filled, they should be regularly sludgedthrough the bottom of the vessel by opening the circuit valves and the

drain and sludge valve until thewater clears. This should berepeated for all the circuits. Afterfilling all the circuits, the circuitpumps should be set running tocheck for further sedimentationarriving in the vessel. When this isclear, the boiler valves may beslowly opened and then the shuntpumps set running.

ATLANTIC BOILERS was formed in 1980 to promote highly efficient boilerplant and within twoyears had supplied the first commercial gas condensing boilers in the United Kingdom. For30 years, ATLANTIC BOILERS has supplied both gas and oil condensing boilers to manyUniversities, Hotels, Hospitals, Medical and Social Care Buildings, Leisure Centres, Schools,Offices and Housing Developments plus many other types of buildings. ATLANTIC BOILERSalso supplies condensing and highly efficient domestic hot water generation, based onstainless steel manufacture.

Coupled with the supply, ATLANTIC BOILERS provides back-up commissioning, spares andservicing by way of a network of merchants throughout the United Kingdom.
