Carrier helps transform landmark Bethnal Green Gas Works Development with FCUs


C


arrier has delivered over 1,000 fan coil units to support the regeneration of Bethnal Green Gas Works into a landmark East


London residential development. Carrier was appointed by installation contractors,


Watkins, to supply 1,027 COMFORT LINE™ Fan Coil Units (FCUs) for the development, scheduled for phased delivery over approximately two years. The FCUs are being delivered with articulated filters and adaptable control systems to match the project’s spatial and acoustic requirements. A key installation challenge was working within


the confined ceiling voids of modern residential buildings, made more complex by the density of building services such as pipework and sprinklers. Space constraints required flexible HVAC solutions that could be changed on-site and integrated without compromising the building’s interior design or service layouts.


There were also logistical and acoustic hurdles: • •


Access hatches were small and restricted.


Strict performance criteria for noise and energy efficiency had to be met, with Specific Fan Power (SFP) and Noise Rating (NR) requirements for residential applications. Bedrooms were required to meet <25NR and living areas <30NR, typically needing additional attenuation.


•


Coordination with other trades was essential due to the configuration of layouts to maximise ceiling heights in living spaces and bedrooms.


The FCUs were equipped with articulated filters. This configuration eased installation in tight ceiling spaces.The modular FCUs offered the ability to reverse handings on site, allowing for swift adaptation to suit access and maintenance requirements. The unit flexibility reduced delays and contributed to smoother installation sequencing. The FCUs also exceeded the <0.5 W/l/s energy efficiency benchmark by significant margins, with SFP


levels of <0.14 W/l/s or less in some cases. The noise, energy consumption and filtration performance data presented by Carrier for its FCUs were a decisive factor in the final specification for the project. The first batch of FCUs was delivered in early December 2024, with subsequent deliveries continuing on a rolling basis.

K65 from Conex Bänninger: the number one choice for high-pressure refrigeration applications


P


erformance in high pressure refrigeration applications is vital and Conex Bänninger’s high strength copper alloy K65 fittings provide a safe, simple and economical solution up to 130 bar. Developed in conjunction with Wieland, the global leader in copper alloy tube production,


K65 was created in response to the increased demand for CO₂ R-744 in commercial refrigeration applications, and in particular supermarkets. As the market phases out high-GWP refrigerants, Conex Bänninger’s K65 braze system provides


installers with a lightweight, easy-to-handle alternative to steel. The material is simpler to cut, faster to transport, and available in a wide range of fittings from 3/8” to 2 5/8”. Standard copper pipe cannot withstand 130 bar, but K65’s copper-iron alloy is engineered specifically


for the demands of high-pressure CO₂ systems. With CO₂ offering zero ODP and a GWP of just one, K65 is identifiable by its slightly magnetic propertyand clear markings. When professionally installed, K65 fittings are backed by a 25-year guarantee.

FULLNESS, the All-in-One heat pump without outdoor unit for Nearly-Zero Energy homes, selected for publication in the ADI Design Index 2025


C


livet presents FULLNESS, the revolutionary all-in-one air-to-air solution without an outdoor unit for single and multi-family applications that exploits heat pump technology to guarantee total comfort for all types of housing solutions: efficiency and sustainability even in small spaces. Feltre, November 3rd 2025 FULLNESS is the air-to-air heat pump with R-454C refrigerant (GWP < 150)


for Nearly-Zero Energy single and multi-family buildings with decentralised system, capable of satisfying all needs: heating, cooling, domestic hot water production, mechanical ventilation with thermodynamic recovery and electronic filtration, dehumidification. Comfort is also ensured by the all-air system that uses heat pump technology to deliver air into the


room at the ideal temperature and humidity conditions, easily selected through a colour user interface that allows the desired comfort conditions to be set in a few simple steps. The low thermal inertia of the air allows the FULLNESS system to quickly reach the set climatic conditions even in conditions where it is necessary to quickly switch from heating to cooling, thanks also to the possibility of working in free cooling. The unit is designed to maintain the temperature of the domestic hot water contained in the optional


tank that can be installed under or beside the heat pump module. Through electronic filtration, FULLNESS allows for the purification of air in any environment and


reduces humidity and pollutants for a natural climate in all seasons. ‘By using controlled mechanical ventilation ducts to maintain room comfort, FULLNESS makes it possible to reduce investment and management costs and simplifies installation, drastically reducing installation times as the heating plant, distribution columns and the installation of the satellite modules required for metering do not have to be built. - comments Stefano De Boni, Clivet Product Manager. - Design is also simplified, offering architects and planners the opportunity to foresee the comfort systems already in the design phase for perfect building-plant integration. A solution that can be easily integrated into the building system, which contributes to increasing the energy efficiency class and therefore the value of the building.’ FULLNESS is designed to be combined with the AIRPATH distribution system, which is suitable for


every plant situation thanks to the flexible, walkable and insulated ducts, which reduce installation space and leave maximum design freedom. The AIRPATH selection software allows to quickly and accurately identify all the elements of the air distribution system, ensuring optimal configurations for every design requirement. The reduced number of elements and Plug&Play connections simplify and speed up installation, guaranteeing perfect tightness and reliability. The silver ion-treated plastic film that covers the ducts provides excellent antibacterial and antistatic properties for maximum fresh air hygiene. The smooth interior ensures low pressure drops, reducing ventilation consumption. The special AIRJET diffusers ensure homogeneous air diffusion. FULLNESS has been selected by the ADI Permanent Design Observatory for publication in the ADI Design Index 2025, the prestigious selection that brings together the best Italian design products nominated for the ADI Compasso d'Oro 2026 award.
