MULTI-BOILER PRE-FABRICATED RIGS
The Keston concept has an established history of reliability, with thousands of boilers being successfully installed in commercial, industrial and domestic premises throughout North America and Europe.
The modular design means almost any heating output
can be achieved. The SEDBUK 'A' rating of our complete
range ensures peak operating efficiencies and minimum
running costs.
Factories, commercial and public buildings, ranging from schools, blocks of flats, offices, hotels, pubs and restaurants through to sports halls, department stores, hospitals and museums, are just some of the applications that have benefited from installing Keston condensing boilers.
The Keston Rigs are delivered to site pre-assembled and incorporate up to five units within a floor standing frame and up to 20 boilers operating in sequence across multiple frames. A dual boiler wall-hung rig is also available. The units are pre-piped to a single balance header.
THE MODULAR APPROACH
The compact size and versatility of the Keston makes it the perfect solution for a modular system, offering the designer complete freedom of choice.
A boiler sequencer is included with integral weather compensating control to ensure optimum use of plant to meet demand and rotation of lead unit.
The balance header includes tappings for air vent; fill point/expansion vessel, drain off and system flow and return. The number and size of system tappings is as per the customer's own specification. RIG OPTIONS
In today's complex design approach it's common to have systems which require a number of different flow temperatures such as underfloor heating, weather compensation, DHW via indirect cylinder, air handling units, etc, the Keston plant rig approach can solve this problem by incorporating diverter valves to selected boiler(s). In this way the selected boilers can be seconded from serving the main system flow to serve another requirement at another flow temperature. Once this requirement is satisfied the selected boilers are diverted back to join the other boilers serving the system at the main flow temperature. Whilst the boilers are seconded away, the rig controller automatically increases the power demand from the remaining boilers to compensate. This can be repeated with other boilers at other temperatures to meet user requirements.
Indeed, Keston can accommodate almost and rig requirement including integrated DHW storage, system pumps, pressurisation units and more.
