Innovative AIC

NESTA and NESTA Plus boiler innovations

The AIC NESTA range of floor- standing, high-efficiency condensing boilers from C&F Quadrant is suitable for either medium or large residential and commercial installations. They are perfect for retrofit or new-build projects and are available in four outputs – 120kW, 160kW, 200kW and 250kW – all with a single enclosure size. The small footprint (0.5sq m) and compact dimensions means they can be installed in areas where space is at a premium.

The internal control unit of Nesta boilers allows for management of cascades up to six boilers in a series of direct and mixed circuits and additional DHW circuit, with boiler management and alarm. The Nesta range is also equipped for remote management via ethernet network or GSM router.

Nesta features and benefits

• Stainless steel heat exchanger; • Self-cleaning flue ways; • Internal circuit piping in welded stainless steel; • Low pressure drop; • Compact dimensions; • Reduced maintenance; • Can be installed in cascade up to six boilers; • Low NOx levels.

The NESTA portfolio has recently been extended to include NESTA Plus, a similar range of floor- standing, high-efficiency boilers but with larger output options of 280kW, 420kW, 570kW and 840kW.

The NESTA Plus high-output, single- pass condensing boilers have an impressive 10:1 modulation range that provides high seasonal returns and significant savings on gas consumption. Linear modulation addresses the needs of higheroutput plantrooms and allows the boiler to consistently achieve maximum efficiency, limiting boiler cycling as much as possible. This technology is effective in both new-build and retrofit heating systems.

NESTA Plus features and benefits

• Stainless steel heat exchanger; • Self-cleaning flue ways; • Internal circuit piping in welded stainless steel; • Low pressure drop; • Compact dimensions; • Reduced maintenance; • Lifting points for transportation and positioning; • Low NOx levels.

The NESTA Plus controller enables remote boiler management by web server connectivity. One of the primary benefits of this advanced integrated control system is the optimalisation of periodic servicing using self-diagnostics to assist the engineer prior to attending site.

At the core of all NESTA boilers is AIC’s stainless steel “Fire Tube” heat exchanger technology. The use of high-grade stainless steel alloys ensures product durability, reliability, and higher resistance to corrosion and oxidation.

Another advantage is the selfcleaning feature. The unique design and orientation of the heat exchanger allows the condensate to run down the inside of the heat exchanger tubes and cleans any possible traces of combustion residue. This function allows the boiler to maintain maximum efficiency throughout the lifespan, leading to reduced running costs and maintenance for the end user.
