Heat and Cold…When it is Needed.

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.

What Are PCMs?
Why Heat Batteries?

Improve Air Quality

Thermal energy stored and re-used to keep engine components operating at peak efficiency means less emissions and cleaner air.

Engine & Cabin Warm Up

Reduces start of day engine idling with fast warm up of engines and cabins, reducing emissions and saving time.

Climate ... Controlled

Simple integration into existing HVAC cooling circuits allows you to store and release heat where it’s needed, improving driver and passenger comfort.
Vehicles Waste Heat, But They Also Need Heat
Sunamp aims to solve several vehicle thermal management challenges with their Heat Battery Technology, by storing excess heat for use when and where it is needed.

Applications and Solutions
Daily Challenges…Solved.
These are some of the various applications of our Heat Battery technology.
The Challenge: Climate impact on range of EVs or refrigerated BEVs.
  • Increased mileage and reduced charging time.
  • 10-100% CO2 reduction, depending on electricity source.
  • £5000 a year saving per vehicle over diesel.
  • Low vehicle noise, allowing night deliveries.
  • Cold store temparature consistency.

  • Low vehicle noise, allowing night deliveries.
  • Cold store temparature consistency.
Cabin Heating
The Challenge: Idling for up to an hour to warm up a bus before leaving the depot. This increases local emissions and reduces fuel economy.
  • Coolant waste heat (from previous drive) used as a thermal source for the Heat Battery.
  • Rapidly pre-heat drive, lower and upper saloons.
  • Cold soak test results indicate 30 minutes reduction in cabin warm up times, with engine idling.

The Challenge: Idling for up to 5 minutes before engine reaches operating temperatures.
  • Rapidly pre-heat engine 5x faster.
  • Small Heat Battery store with high power.
  • Can be packaged under the bonnet.
  • 3-4% reduction in CO2 emissions (NEDC simulation).

What Are PCMs?
We Develop and Manufacture Our Own PCMs.
Sunamp has developed a range of PCMs to work at many temperatures

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.
