Climatic Wind Tunnel (CWT One)
Our advanced CWT One facility enables customers to test their products under a wide range of simulated, repeatable environmental conditions including extreme cold, snow, solar loading and humidity.
The facility features a 4 wheel drive dynamometer and is utilised by a number of international vehicle manufacturers looking to develop their products for all world markets.
By reducing the need for seasonal in-territory testing, the facility allows customers to compress their development lead times, helping them to deliver products to market far quicker than their competitors.
We offer the following tests in this facility:
- Defrost/Demist
- SC03
- FTTP (Fuel Tank Temperature Profile)
- ATCT (Ambient Temperature Corrected Test)
- UDDS (Urban Dynamometer Driving Schedule)
- WLTP (Worldwide Harmonised Light Vehicle Test Procedure)
- Snow Packing
- HVAC Performance
- AC Pulldown
- Cold Start
- Motorcycle Lugging & High Speed
- EV Range
- Driven Rain
