[Birmingham, UK. Sep 2023] Grayson Thermal Systems (GTS), a leading name in thermal management solutions for the zero-emission vehicle space, is set to unveil its latest heating and cooling advancements at two prestigious international trade shows: Europe’s Busworld and North America’s APTA Expo.

From October 7th to 12th, 2023, GTS will proudly exhibit at Busworld in Brussels, Belgium (stand 638, hall 6) and highlight its pioneering thermal management solutions for the next generation of zero-emission buses. This marks the return of Europe’s largest trade show dedicated to the bus and coach sector after a four-year hiatus.

From October 9th to 11th, 2023, GTS Corp, the North American division of the Group, will return to the APTA Expo, taking place in Orlando, Florida (stand 3767). Targeted at the North American public transportation sector, the event will see audiences become acquainted with GTS’s vast array of climate control systems and components.

The events follow the company’s recent accomplishment of developing a complete Vehicle Thermal Management System (VTMS) for the world’s most energy-efficient electric double-deck bus. GTS will now use the exhibitions to showcase its popular third-generation Battery Thermal Management System (BTMS) range, catering to OEMs of battery electric and hydrogen fuel cell vehicles. These cutting-edge battery chillers, configurable to suit the ambient, are also available as a hot water heat pump. The small but mighty package leverages GTS’s efficient refrigeration technology to maintain optimal performance.

Visitors to both trade shows will also have the exclusive opportunity to get hands-on with GTS’s new Magdrive Electric Water Pump, featuring heavy-duty magnetic coupling technology for unmatched reliability and durability. This innovative addition to the Electric Water Pump category builds on the success of GTS’s Mechanical Seal unit.

Stuart Hateley, Managing Director of Grayson Thermal Systems, commented: “We are thrilled to return to Busworld and APTA with a range of ground-breaking developments to share with the industry.

“Since the last Busworld in 2019, we have invested significantly in our New Product Development initiative, pushing the boundaries of heating and cooling for the next generation of zero-emission applications. Having sold over 4,400 of our BTMS, VTMS and Heat Pumps in the past three years, our systems can now be found delivering exceptional cabin, saloon and battery climate control across the globe.

“GTS is now well-positioned to build on this success with new advanced systems and a strong sales pipeline in both the North American and European markets. We look forward to meeting new and existing contacts across different continents, sharing our exciting product developments, and demonstrating how we can support OEMs with their upcoming projects.”

In addition to the BTMS and Electric Water Pump ranges, Busworld attendees can gain insights into GTS’s electric motor and power electronics cooling modules built for battery electric buses.

Meanwhile, APTA Expo visitors will have the opportunity to delve into the manufacturer’s range of HVAC solutions and high-quality components, including the GTS Electric Water Heater range, offering up to 35kW of instant heat for batteries, saloons, or cabins, popular in the extreme cold ambients seen in North America.

Throughout both events, GTS’s thermal management experts will meet with visitors and share their knowledge. To schedule a meeting with one of the GTS team members at the respective stands, attendees are invited to book an appointment via the following links:
