Ruskin thinks ‘out of the box’ with new fan coils

Ruskin Air Management has developed an industry first total system approach to fan coil projects, which can reduce installation costs by 70%.

Its Hydropac EC fan coil units (FCUs) are now available as a complete ‘straight out of the box’ system; including fully integrated controls that are factory set to improve accuracy and minimise commissioning time on site. This ground breaking approach to the traditional business of manufacturing and supplying FCUs promises better long-term performance from the installed system and considerably cuts upfront costs.

Ruskin, through its group companies Actionair and Air Diffusion, takes full responsibility for the design and system components, including modulating valves, actuators and sensors, to ensure the complete package works in harmony and is tuned to match demand patterns in the building before it leaves the factory.

The system is manufactured in the UK and, by integrating the controls from the outset; Ruskin is avoiding many of the pitfalls created by having to co-ordinate a number of different suppliers. There are no special software tools needed to ensure the system is commissioned and calibrated as this is all taken care of by Ruskin’s in-house engineers.


There is also no need for the installer to carry out the usual water flow commissioning tasks as the FCUs arrive on site ready to ‘plug and play’. Wiring costs are also reduced because the Hydropac system is line voltage powered.

Ruskin provides an online selection programme that allows specifiers to witness how the system is put together; the impact of adjusting air and water temperatures; and to stipulate their own control options. Tests can also be witnessed at the group’s state-of-the-art facility in Whitstable, Kent.

Hydropac FCUs are equipped with the latest variable speed EC external rotor motor technology, which is particularly efficient at low speeds when compared with traditional motors. The motors are cold running and the system is built around load dependant control, which reduces the amount of air passing through each unit. This increases motor operating life by 50% to an estimated 50,000 hours or 30 years usage in a standard commercial office building.

The FCUs also comfortably meet the stringent Part L 2013 requirement of 0.5 W/(l/s) of air delivered, and in most cases, will be well below 0.35 W/(l/s). They are also very quiet in operation, thanks also, in part; to the fact they come as a pre-engineered complete system.

“The demise of the fan coil, which was predicted some years ago, has clearly not materialised,” said Ruskin managing director Kevin Munson. “In fact, this tried and tested approach to managing the cooling and heating needs of commercial buildings is more popular than ever – in both new build and refurbishment projects.

“Often dismissed as a ‘cheap and cheerful’ option in the face of more sophisticated air conditioning systems, FCU technology has surprised its critics by becoming more adaptable, quieter and more energy efficient. Ruskin’s new ‘system approach’ is the latest stage in the evolution of this popular, cost effective and flexible solution,” said Mr Munson.
