Grayson Thermal Systems keep it cool with E-Drive success

30th March 2017

Winter is finally on its way out and the summer months are looming, but with the warmer climate comes the annual challenge of soaring engine heat and the associated increase in vehicle overheats, resulting in lost mileage and additional operating costs.

Grayson Thermal Systems has the answer. The world’s leading provider of engine cooling, heating and air conditioning products is enjoying great success with its innovative E-Drive electric fan system, reducing operator costs and environmental impact, aiding noise reduction up to 30% whilst in service and achieving up to 10% savings on fuel costs.

With the company’s outstanding build quality and unique configuration, this electric fan drive cooling system is an innovative solution that replaces traditional hydraulic/viscous fan systems found on passenger service vehicles and is the lightest most efficient fan on the market.

First sold in 2011, the E-drive continues to meet demands within the industry to reduce emissions and costs with no sign of orders slowing.

Stuart Hateley, Managing Director, commented: “We have a healthy 2017 order book for the E-drive, with over 800 systems scheduled for aftermarket retrofit so far this year.

“The Grayson designed and manufactured E-drive has fast become the number 1 choice, and is now OE fit with a number of vehicle manufacturers. With 5-year cover on all major parts and components when taken with the 5-year maintenance package, our customers can have complete peace of mind.”

With over 80 years of industry knowledge, the Hateley family have been building heat exchangers since 1935. Graham Hateley, the current Chairman, incorporated Grayson Thermal Systems in1978 and so the journey continues….

Things have changed a lot since the early days and, in more recent years, the company has invested heavily in its brazed aluminium technology centre, which is now delivering in excess of 1000 heat exchangers per week to its global customer base.

The 25-strong engineering team continues to create class leading products that are playing a critical part in cooling system performance.

This includes using thermal simulation and performance mapping to design one of the most efficient Transit bus cooling systems in the world and development of a rigorous new testing system that ensures each cooler passes over 1 million pressure pulsation cycles and 10,000 thermal fatigue cycles.

Stuart went on to add: “Our unique fin and tube designs allow us to ensure not only does the product perform when new, but maintains great performance throughout years of operation.

“Yesteryears older plate and bar construction heat exchangers just do not offer the same thermal performance, weight and cost point that our own product delivers today.”

Grayson Thermal Systems’ experienced design team can provide a bespoke ‘E-Drive’ solution based on individual specifications and are equipped to retrofit your current hydraulic systems with minimum on-costs and around a 12 to 15-month payback.

Ian Hateley, Technical Director, concluded: “We take great pride in leading the market on new thermal management systems. Quality in our product and service remain the key drivers of the business, ensuring longevity of life in both the systems provided and the customer relationships they are built on.”
