Sustainable technology to achieve things never thought possible.
Enabling net zero.
Transforming high-speed flight.
Pioneering access to space.
We are a privately held technology Company pioneering space access and sustainable technologies. For over 30 years we have been at the forefront of engineering innovation – including developing SABRE, a revolutionary new class of aerospace propulsion. SABRE enables us to go beyond the limits of flight both within and outside the atmosphere. Making space travel and high-speed flight more efficient, more accessible, more possible.
Developed for SABRE, our proprietary precooler technology is truly transformational. It delivers world-leading heat transfer capabilities across diverse industries to improve performance in motorsport, enable waste heat to be captured for conversion to electricity and support more sustainable aviation. These revolutionary thermal management solutions have the potential to elevate life on Earth.
