British heating and cooling equipment specialist Diffusion has launched the new Ultra-Line 360 fan coil unit (patent-pending) designed specifically for exposed-ceiling applications. Ideal for office, retail, and hospitality projects, the UK-designed and manufactured Ultra-Line 360 combines the proven performance of Diffusion’s established award-winning Modular Highline Fan Coil technology with a unique diffuser and integrated plenum developed to deliver high-performance heating and cooling and thermal comfort, while complementing contemporary architectural aesthetics. Offering true 360-degree air distribution through the Coandă effect, the new unit has been designed to simplify specification, installation, and maintenance by eliminating the need for ductwork, separately specified attenuator, plenums, diffuser and grilles, helping reduce installation time, coordination requirements and associated project costs.

With the growing trend for industrial style interiors with exposed ceilings across commercial developments, architects and designers are increasingly specifying solutions that deliver high levels of comfort and performance without compromising on the design. Developed specifically for these applications, the Ultra-Line 360 combines the proven technology used throughout Diffusion’s CIBSE award-winning Modular Highline Fan Coil range with an innovative diffuser designed by Diffusion and engineered to optimise and deliver energy-efficient air distribution across the larger spaces. By harnessing the Coandă effect, conditioned air remains close to the ceiling surface before gradually mixing in the occupied space, helping deliver energy-efficient comfort without requiring high airflows or additional energy consumption.

Alexis Roberts, Channel Marketing Manager at Diffusion, said:

“As exposed-ceiling designs become increasingly popular, specifiers are looking for solutions that deliver high levels of comfort and performance without compromising aesthetics. The Ultra-Line 360 combines the proven performance of our award-winning Modular Highline Fan Coil range with a bespoke diffuser and integrated plenum developed specifically for exposed ceiling applications. By harnessing the Coandă effect, the unit increases occupant comfort as it can distribute air effectively across the wider space without requiring high airflows and additional energy consumption. Low sound is key to exposed units, and here too the Ultra-Line delivers.”

“At the same time, because no ductwork or separate air distribution components are required, installation is simpler, fewer trades are involved, reducing coordination on site. Projects can also benefit from fewer fan coil units, reduced material use and embodied carbon, lower installation costs, less time on site and lower overall project costs.”

Performance and occupant comfort are central to the Ultra-Line 360’s design. Building on Diffusion’s award-winning Modular Highline Fan Coil range, the unit combines proven EC/DC motor and fan technology with a high-efficiency heat exchanger to deliver high performance and low noise operation. Offering sounds levels as low as NR25 for 125l/s and a low Specific Fan Power from just 0.05W/l/s, the Ultra-Line 360 has been engineered to provide energy-efficient operation without compromising comfort. The Ultra-Line 360 also benefits from heat exchangers specifically designed to achieve optimum heating and cooling performance using industry-standard hot water and chilled water temperatures.

A key differentiator with the Ultra-Line 360 is Diffusion’s bespoke diffuser, which has been designed and manufactured in-house to harness the Coandă effect and optimise airflow within the occupied space. By causing conditioned air to remain close to the ceiling surface before gradually mixing into the occupied area, the diffuser enables air to be distributed over longer distances without increasing airflow rates. This helps minimise draughts, reduce hot and cold spots and prevent cold-dumping, creating a more consistent and comfortable indoor environment. The Ultra-Line 360 ensures 360-degree air delivery, providing energy-efficient, enhanced thermal comfort for occupants.

Engineered for today’s offices, retail, and hospitality environments, Ultra-Line 360 combines Diffusion’s award-winning technology with a versatile modular design. Key to the Ultra-Line design is the complete integration of all core components within a ceiling-exposed unit that distributes the air using the Coandă effect, with no ducting required and no diffuser or plenum to mount. This significantly reduces on-site coordination, air distribution equipment, installation time and costs. 

Meanwhile, Diffusion’s Lifetime ‘Eco’ wire mesh filter is supplied as standard, alternatively, ISO grade 30% coarse media filters can also be supplied. The Lifetime ‘Eco option provides a robust, environmentally conscious solution that can be vacuum cleaned in situ, opting for this filter eliminates approximately three synthetic filters a year going to landfill. Filters can be easily removed on-site from the side of the unit.

Offering flexibility, there is a range of options available to help specifiers meet project requirements. Customers can choose whether to select either a gravity condensate connection, or the ultra-quiet Maxi-Blue condensate pump. Diffusion can also fit controls equipment to customers’ own specifications, or Diffusion’s factory-fitted proprietary option, choosing Ultra-Line offers complete flexibility. Supplied in galvanised steel, the Ultra-Line 360 can also be powder-coat finished in a customer-specified RAL colour to suit interiors.

Reconfigurable and sustainable, the Ultra-Line 360 is ideal for buildings where a change of use is anticipated. Core components can be re-configured, relocated, or reused within another Diffusion product from the modular range of units, further endorsing the benefits of the modular range. This delivers substantial benefits in reducing waste, landfill, installation time, and capital expenditure over the building lifecycle.

Designed and manufactured in the UK Diffusion’s Ultra-Line 360 reflects the expertise of the company’s dedicated in-house design team. Every element has been carefully considered to design the next generation of fan coil units, providing an energy-efficient fan coil unit to meet aesthetic, comfort and performance requirements while ensuring easy service and maintenance. 

To give specifiers a closer look at the engineering technology behind the Ultra-Line 360 and its wider fan coil range, Diffusion hosts regular Open Days at its UK manufacturing facility near Hampton Court. Here, visitors can see fan coil units assembled on the production line; tour Diffusion’s testing rooms, where customers can witness acoustic, volumetric and thermal testing; and meet the Diffusion team, including Technical Director, John Hepper

Consultants wishing to extend their visit can stay for lunch and attend a CIBSE-Approved CPD session, combining structured learning with practical insight.
