Cougar Fan Coil Unit.


The Cougar manufactured by Dunham-Bush is a high quality, compact, 'slim-line' range of fan coil units, designed to fit in to the shallowest of ceiling voids and perform quietly and powerfully for many years to come.

Cougar fan coil units are built to no-compromise engineering standards using only the most modern and reliable components available. Combined with the very latest design and manufacturing technology, the 'Cougar' provides the ideal solution where ceiling void space is at a premium.

Careful consideration has been given to safe site handling, fast/simple installation and ease of access for maintenance. Designed to offer maximum site flexibility, the 'Cougar 'is one of the most versatile and user-friendly products available in today's market.

Flexibility Is The Key

The 'Cougar' uses a non-handed, dual-purpose coil block covered by a stainless steel 'V' formed condensate pan, terminating with a central drain point at the lowest end of the tray. This universal design is used on both RH and LH configurations and allows the complete coil and condensate pan assembly to be site reversible without the need for any additional parts or metalwork.

The discharge plenum is supplied with a combination of spigots and blanking plates that are screw fixed to the plenum for ease of site interchange. The added facility to re-locate the controls box from one side of the unit to the other gives the 'Cougar' the flexibility to accommodate site layout changes and client fit-outs.

Simple Access For Maintenance

Removing large panels secured by 10-20 screws and then getting them through a 600mm x 600mm ceiling grid, all whilst stood on a stepladder, has made life difficult for the maintenance engineer in the past. Special consideration has been given to overcoming these problems and the resultant 'Cougar' now brings a 'breath of fresh air' to maintenance tasks.

Filters are simple to remove for cleaning - they withdraw from either the rear or side of the unit without the use of tools or the need to remove panels. The main unit access panel is secured by quarter turn 'quick release' fasteners and gives access for inspecting the fan/motor assemblies.

Each fan/motor is mounted separately onto the main bulkhead plate to facilitate easy removal of an individual assembly in the unlikely event of needing to be replaced. On model sizes 4-7 both the filters and fan access panels are split into two smaller sections for easier removal and handling. Electrical and controls work can be easily carried out via a hinged cover giving access to all components housed in the box. The stainless steel condensate pan can also be easily removed for cleaning via its own separate access panel.

Quiet, Powerful Operation

The Cougar incorporates high performance, single inlet, external rotor motor fans as standard. The fan/motor assemblies are individually mounted on to a 'floating' bulkhead plate, isolating them from the rest of the unit chassis, reducing resonance and casing breakout noise. Controlling the fans via the auto-transformer ensures greater performance flexibility. Twelve fan speeds are available via four main transformer tappings each linked to three 'fine adjustment' settings for accurate site commissioning. Use of the highest quality components available is never more important than in the case of the fans/motors to ensure that quiet and powerful operation is consistently achieved year after year.

Long Life Stainless Steel Condensate Pans

Cougar fan coil units incorporate stainless steel condensate pans as standard. By using stainless steel, cleaning is made easier whilst the resistance to corrosion is increased, vastly improving the longevity of the pan. The fully welded 'V' formed pan creates a positive seal against the coil preventing any air bypass. The pan is mounted to provide a positive fall in two directions to the central outlet at the lowest end of the pan. The 22mm stainless steel outlet is welded flush with the bottom of the pan ensuring that condensate flows freely and completely away. The externally insulated pan is mounted in a separate galvanised steel carriage, removing the need for screw fixings in the actual pan. This carriage combined with the inherent strength of the stainless steel pan and outlet offers vital protection against accidental site damage.
