Diffusion’s New Range Creates Perfect Indoor Environment

  • 31 May 2023

British heating and cooling equipment specialist Diffusion launches its new Highline 235 modular fan coil range – differentiated by design, it has been developed to create the perfect indoor environment at work and at home.

With quality, performance and flexibility at the heart of everything Diffusion does, the Highline 235 range of fan coil units offers modular design, compact dimensions and advanced components that deliver low sound levels, reduced energy consumption and optimal performance. Comprising eight models, including 13 fan combinations, the Highline 235 range suits a wide variety of applications.

The new Highline 235 range of fan coil units boasts exceedingly low sound levels. Delivering noise ratings as low as NR25, ensures their suitability for a wide variety of commercial applications including offices and particularly residential applications and hotels where quiet operation is critical.

The Highline 235 has been designed with aesthetics in mind, this makes it an attractive solution for architects that require a ceiling exposed solution, as well as those that prefer ceiling concealed units.

Meanwhile, the range’s high efficiency EC motor and fan assemblies provide improved Specific Fan Powers (SFP) as low as 0.14 W/l/s, reducing overall building energy consumption. Plus, the Highline 235 range provides increased performance due to heat exchangers specifically designed to achieve optimum heating and cooling performance using the industry predominant hot water and chilled water temperatures.

Featuring excellent build quality, the new Highline 235 range is built to last with a galvanised steel chassis for increased durability. Benefitting from its own in-house Design team at Diffusion, and the company’s extensive industry experience, every aspect of the fan coil design has been considered to improve performance, whilst also making the fan coils easy to service and maintain, even in confined spaces.

This is largely thanks to a full width access panel giving easy access to key components including the heat exchanger and fans. Meanwhile, the Diffusion Highline 235 range’s modular design delivers ultimate flexibility, enabling attenuator and plenum options to be easily configured to suit the application.

Design options are almost limitless as the Highline 235 is completely customizable with almost 300,000 configurations allowing customers to choose the fan coil that fits their individual design. This is of particular importance to buildings that have a change of use, as the units can be re-configured on-site to suit the new purpose of the building and new configuration, this saves purchasing new models which is costly and wasteful – a significant sustainability benefit.

John Hepper, Technical Director at Diffusion, comments: “We are delighted to launch the new Highline 235 range which is almost endlessly configurable, and offers quiet, high performance and energy efficient heating and cooling for the perfect indoor environment. Thermal comfort is an important factor in modern buildings and our newly designed Highline 235 range has sizes for all types of applications from hotel rooms to reception areas and offices.

“The Highline 235 incorporates many components that have been designed to improve quality, enhance efficiency, reduce sound and optimise overall performance of the product. These design enhancements are the direct result of Diffusion’s close relationships with our customers and a deep understanding of their project needs.”

All elements of the Highline 235 range have been designed with product performance, ease of installation, and service and maintenance in mind. The condensate drip tray and 22mm diameter drain connection is made from stainless steel for rigidity and longevity, the entire tray can easily be removed on-site for cleaning while the drain connection is located at the lowest position of the condensate drip tray and fitted with a void tray so condensate can drain away easily. 

The fan coil range can be supplied with either ISO grade media filters or the Diffusion lifetime ‘Eco’ wire mesh filter, this option provides a robust environmentally conscious solution that can be vacuum cleaned in situ. The filter can also be easily removed on-site from either the side of the unit or from beneath the unit.

The filters on the larger models are split into two parts, making them easy to remove or clean, this is particularly beneficial when the unit is installed in confined or awkward spaces. Meanwhile, the fan coils are supplied fitted with a controls enclosure which is mounted to the side of the unit for convenience and easy access, this can also be placed away from the unit should this be a requirement for your application.

Forward curved centrifugal fans are used in all models providing the most efficient airflow and acoustic performance. The fan coil units are insulated throughout with class ‘0’fire-rated foam, the thickness of the insulation throughout the unit varies to ensure superior thermal and acoustic performance, 70% of the foam is either 12 or 25mm thick. Diffusion’s new Highline 235 range is compliant with all key performance standards.
