Grayson Thermal Systems – The leading supplier of Cooling, Heating & Air Conditioning Products

Grayson are a specialist engineering company with a strong reputation for quality, innovation and working in partnership with customers. We pride ourselves in being able to develop and supply solutions to specific business issues.
We design and manufacture OE and aftermarket cooling and heating products for bus and coach, specialist off-road vehicles and commercial vehicles. Our customers include some of the best known OE manufacturers and vehicle operators.
We are a proud Birmingham business with two extensive manufacturing facilities, dedicated engineering, research and test operations, and a separate service centre. From the heart of England, we serve customers in Britain and right around the globe. Client locations range from China, the US, Eastern and Central Europe and New Zealand. We have opened Grayson North America Corporation, and plan a further programme of satellite businesses across the world.
Grayson has come a long way since 1978 when chairman, Graham Hateley, opened a radiator repair business from a small unit in Hay Mills, Birmingham. Now, we are a proud family-run business with an excess of 290 employees across two continents. Our employees include three generations of the Hateley family.
More importantly, we’re still brimming with new ideas to take us – and our customers – through the next generations.
We are ISO 9001:2015 certified. Click Here if you would like to view our certificate of registration.
