Ultima Water Cooled Chiller &
Ultima Remote Air Cooled Chiller
The Ultima Water Cooled (UWC) and Ultima Remote Air
Cooled Chillers (URAC) are some of the most advanced
chillers ever produced by Airedale, thanks to our on-going
programme of extensive development and technical
innovation. The new ranges have been designed specifically
for use in plant room applications with energy efficiency, low
sound levels, cost effectiveness and the environment in mind.
Heat rejection can be achieved through either water or
refrigerant by means of a dry cooler or remote condenser.

Key Feature : Low Sound Levels
Airedale recognises that noise pollution is a very important issue in today’s populated environments, with many urban areas
having already introduced strict noise pollution regulations. The new UWC and URAC have been developed with low sound
levels as a key factor in their design.

Key Features
Key Feature : Electronic Expansion Valves
A standard thermostatic expansion valve cannot control the refrigerant superheat and therefore prevent the flow of liquid
refrigerant out of the evaporator at low condensing temperatures, so a head pressure controller is fitted to maintain an
artificially high head pressure so conventional air handling units can operate reliably, but this means the refrigerant system
unit is not running as efficiently as it could do at lower ambient temperatures.
The UWC and URAC use electronic expansion valves as standard. The valve can operate at much lower condensing
temperatures, reducing the need for unnecessarily high head pressures, and as a result significant compressor energy
savings can be achieved whenever the ambient temperature and / or cooling requirements are below design conditions.

Key Feature : Multiple Scroll Compressor Technology
Airedale are utilising multiple scroll compressor technology for the very first time to achieve cooling capacities of up to
450kW on dual circuit machines. The use of this technology brings with it greater flexibility to the Ultima Chiller range.
The vertical orientation of the compressors means the UWC and URAC have a more compact footprint than other 450kW
chillers, and lower vibration levels means they are quieter than other chillers in this capacity range.
The multiple scroll compressors are also considerably more efficient achieving EER values of above 4.0* at nominal
conditions, as well as being more resistant to liquid flood back which enhances unit reliability and life cycle costs.
* Based on nominal water cooled conditions.
Key Feature : Victaulic Pipe work Connections
Airedale utilise Victaulic pipe work on the UWC and URAC as standard. These (cost
option) ‘clamp type’ connections have a range of additional features and benefits
over the flanges traditionally used on all water connections.
> Flexible joint – This can accommodate pipe expansion and contraction due to
changes in temperature, as well slight misalignments in pipe work, often
removing the requirement for expensive on site re-work
> Easy maintenance – Just two simple bolted connections to make a joint
> Noise dampening – Through the use of the integrated rubber gasket section
of the joint
> Even pressure – This is evenly applied around the entire pipe, unlike a flanged
connection where pressure is focussed on the 10-12 bolt holes
> Reduced welding – the Victaulic connections greatly reduce time spent
welding, and the variety of fittings available can also reduce the amount of
welding that is required
