Nothing demonstrates problem-solving abilities and expertise more than real-world examples, and one of the most impressive is the award-winning Sir Chris Hoy Velodrome in Glasgow,a world-leading cycling facility with an optimal indoor climate. Providing a chimney system designed to suit the overall appearance and architecturally significant design was a primary focus when specifying the system requirement of the flue system. To maintain indoor temperatures whatever the Scottish climate offers, Hoval Condensing boilers temper and heat the fresh incoming air ensuring optimal indoor cycling conditions. Chimney Specialists JRF were asked to formulate an elegant, efficient, and cost-effective proposal. Working in conjunction with SFL a NOVA® twin wall flue system was specified, full technical details were calculated and confirmed enabling the supporting mast structure and associated civil groundworks to be incorporated into the overall design. Serving these high-efficiency boilers a double stack and mast supported SFL Nova® Twin Wall chimney system designed and installed to fully meet the project requirements.
SFL are committed to offering industry-leading technical support, throughout the complete process of design, manufacture, and supply of every project. Their experienced team are on hand to assist at every stage of the process. From initial product selection to flue routing and calculations. From complex header configurations to large-diameter stacks, SFL accommodate almost every requirement for any application, like this project at Lymington Hospital. When flue specialists FBS were contracted to replace an existing flue dilution system for 6 Asida 475Kw condensing boilers using SFL’s EUROPA® and SUPRA PLUS® systems to complete the overhaul replacement at Lymington Hospital in Southampton SFL were on hand to assist.
FBS Flues recommended the entire removal of the flue dilution systems and replacement with two independent conventional flue systems each serving three boilers. 300mm I/D SUPRA PLUS® flues were used to connect each of the boilers into two 600mm I/D common single wall EUROPA® common headers. Each header connected to 600mm I/D, 25mm insulated, EUROPA® flue system rising through the flat roof utilising existing high-level ventilation fan openings, then ran vertically to a height of 6.9m above the roof to ensure compliance with current Clean Air Act regulations. Each flue was supported with two levels of stainless-steel guy wires with one rigid tie bar between the two flues for added strength.
Since 1969 SFL have been leading the way in flue and chimney innovation and technology. From flues and chimneys for data centres, hospitals, stadia and even coffee roasters, by definition, critical business operations that demand zero downtime. They understand that a single data centre can have 20, 30 or more standby generators that all need to be vented, often requiring 10-30m exhaust systems. Working with carefully selected partners they can deliver turnkey solutions, installing exhaust systems with the industry’s most thorough testing and approvals rating ensuring trouble free operation, providing peace of mind for secure environments.
Exhaust systems for emergency backup generators in data centers.
The explosive growth of data traffic worldwide requires the construction of more and more data centers. The continuous functioning of the data center is very important and at the same time challenging, as the availability of the information must be assured at all the times. Therefore, each data centre has back-up generators which ensure uninterrupted working in the event of a power failure. The backup generators need a pressure tight exhaust system which is also suitable for high exhaust temperatures. SFL, provide high-quality, certified exhaust systems that are perfectly tailored for such an application. Fire Resistance Tested to BS EN 1366-13 – Fire resistance test for service installations (Chimneys).
Experience matters – because each project is unique.
SFL’s partners work with the utmost discretion and have vast knowledge of this specialised and important area of data centre operation. They work closely with clients and contractors to ensure the project is delivered smoothly and safely.
The Roasting Party, a simply superb, delightful speciality coffee roasting facility in Winchester, required a fume extract system for their roasting machines. FBS Flues, were the specialist installers on the project, they selected SFL’s EUROPA® and SUPRA PLUS® flue systems which are the expert’s choice for a coffee roasting flue system. Our EUROPA PLUS® flue is ideal for use with appliances ranging from coffee roasting machines to back up generators. Available as standard comprising a 316L Stainless Steel inner and 304 Stainless Steel outer cover with 25mm thick Insulfrax AES blanket insulation all ensuring efficient and safe installation in a multitude of system configurations. SUPRA PLUS® is a single wall stainless steel chimney for 80mm to 350mm diameter systems designed with the commercial installer in mind. Pre-fitted seals make it a go-to product for any commercial condensing and positive pressure applications.
SUPRA XL® is a single wall stainless steel flue and chimney for 400 to 600mm diameter systems.
