See how a London city centre developm ent used biofuel on page 44. SUSTAINABLE ENERGY OPTION Key benefits: Using innovative design for delivering excellent hydraulic and combustion performance, the Ensbury offers versatility in system applications. ‰‰ Natural gas, LPG propane, oil, biofuel or dual fuel burners ‰‰ High/low or modulating burners ‰‰ Low NOx burners ‰‰ Flue gas economiser (see page 46) Options: Low temperature, high efficiency, floor standing steel boiler. ARNE ECONOMISER Increase the system efficiency by combining the Ensbury with the Arne flue gas economiser. Use with single & multiple boiler applications. See page 46 f or more information. INNOVATIVE DESIGN Design features enable return temperatures to as low as 15°C whilst preventing the formation of condensate. Combined with the low flow capability this allows the Ensbury to operate with a wider differential temperature and tolerate fluctuating operating conditions. Minimum flow temperature must be maintained. Injection chamber System flow System return Hot water flow
