An introduction to Diffusion Diffusion, a leading British manufacturer, has been designing and manufacturing heating and cooling equipment in the UK for over 60 years, with the Diffusion sales and technical team boasting over 200 years of combined industry knowledge. Through working closely with customers, Diffusion has established an enviable reputation for the quality and reliability of product, the bespoke design capability, and excellent, personal service. Its competitively priced product portfolio comprises a wide range of fan coil units. Diffusion’s main objective is to design and manufacture high-quality solutions to meet clients’ needs, designing and manufacturing energy-efficient HVAC equipment that can accommodate specific requirements in the most cost-effective way, where the standard is never compromised.
Products available from your company Diffusion offers a range of fan coil units, ranging from standard, specialised to bespoke. Fan coils can be designed and manufactured to meet many applications in a variety of configurations, sizes, and finishes to achieve customer requirements.
The energy efficiency benefits of the range Improvements in fan coil technology have led to lower energy consumption and quieter operation. Advanced designs optimise airflow and thermal transfer, cutting down on energy use. High- efficiency EC motors and fans deliver improved SFPs as low as 0.12 W/l/s, helping reduce overall building energy consumption.
Features that simplify maintenance The award-winning Modular Highline Fan Coil
Range has been developed for performance and practicality, every element has been carefully considered to improve performance while ensuring easy service and maintenance, even in confined spaces. All core components within the fan coil unit can be accessed from beneath the unit for maintenance. Demonstrating Diffusion’s commitment to continuous improvement, a new development is the introduction of a specific side access variant. This simplifies service and maintenance, particularly where services are located in ceilings, which prevent access to fan coil units from below. This new side access option enables the maintenance of the fans simply by sliding them out to the side of the unit, ensuring accessibility even in restrictive installations.
Diffusion’s commitment to Net Zero goals Diffusion is committed to sustainable manufacturing. By prioritising locally sourced materials from UK manufacturers and suppliers, designing products using fewer materials, and utilising the most energy- efficient components, ensures optimal performance with minimal environmental cost. Additionally, with approximately 60% of its fan coils delivered within a 30-mile radius, it minimises transport emissions. Engineered for adaptability, Diffusion’s units can be re-configured to meet changing building needs, avoiding costly refurbishment and product waste. Diffusion developed its own Lifetime ‘Eco’ mesh filter made from sustainable, non-synthetic materials, eliminating the use of synthetic filters that contribute to landfill. To help customers understand its products’ wider life cycle assessment, Diffusion is proud to have completed the CIBSE TM65 collection data for Embodied Carbon Calculations for its entire product portfolio, including its new Modular Highline Range.
Modular Highline Fan Coil Range T
he award-winning Modular Highline Fan Coil Range was initially launched in 2023 with the Highline 235. The range has now expanded with Diffusion’s
new, higher capacity Highline 275, which provides airflows up to 514l/s, ensuring even large-scale spaces can benefit from the range’s unique modular design, such as reception areas and offices. Both the Modular Highline 235 and the Modular Highline 275 come in a choice of 8 sizes, including 13 models to choose from, eliminating the need to over- specify. Meeting noise ratings as low as NR25, the Modular Highline range is ideal for applications where quiet operation is vital, including high-end residential and hotels due to the range of attenuators available. In addition, advanced fan design enables greater
efficiencies, delivering Specific Fan Power (SFP) levels as low as 0.12 W/l/s. The fan coil units also offer optimum performance with their heat exchangers designed to achieve optimum heating and cooling performance using industry-standard hot and chilled water temperatures. Meanwhile, the unique modular design delivers greater flexibility and ease of access to core components in situ. The modularity enables the unit to be reconfigured when required. Both of features ensure the increased longevity of the fan coil units, saving landfill and capital cost.
The advantages of modular design? Modular fan coil design is particularly important to buildings with a change of use. They can be reconfigured on-site to align with a building’s new purpose, resulting in substantial sustainability benefits. The modular design avoids the need for new fan coil units and eliminates the need to discard existing ones, which significantly minimises capital cost, on-site disruption, and waste. Instead, the Diffusion modular design enables fan coils to be reused, reducing a building’s overall embodied energy. Modular design, therefore, offers customers flexibility, quality, and adaptability for future use, ensuring longevity and delivering cost advantages.
What sets Diffusion apart from competitors Diffusion is a British manufacturer offering customers fan coil design and build for over 60 years in the UK. Having expert in-house knowledge offers incalculable benefits to Diffusion’s customers who can benefit from the knowledge that, not only does it have a diverse range of standard products but it has the in-house capability to design and manufacture bespoke products for any specific project application required. At Diffusion’s facilities, clients can observe their product during testing. These tests are conducted in accordance with a detailed method statement explaining each stage of the performance testing process therefore, the client can feel assured that the product will meet or exceed their precise project needs and be certified in their presence. Diffusion offers Volumetric, Acoustic and Thermal performance testing. In addition, it also commissions the industry’s reputable SRL Technical Services Ltd, an independent test facility to verify the sound test results, giving further peace of mind to customers.
