Driving Fuel Economy Up
and Emissions Down
Sunamp Automotive
Sunamp develops, manufactures and sells compact, highly efficient advanced thermal storage technology called Heat Batteries that can be used to store heat and cold for a number of applications.
Sunamp batteries are based on Phase Change Materials (PCMs) that have high energy and power densities and yet are non-toxic, environmentally friendly and safe.
Our Heat and Cold Batteries help reduce emissions and improve air quality and address vehicle thermal management challenges such as engine and cabin warm up, catalytic converter temperature fluctuation and battery thermal conditioning and HVAC systems.

Sunamp Phase Change Materials (PCMs) are non-toxic, non-flammable and eco-friendly. They are patented in the UK and China, with patents pending in other countries. We have developed PCMs that operate at different melt and freeze temperatures to maximise system performance across a range of temperatures.
