Thermo King Coaches HVAC issued a “Call for the Longest-Used Products” to China and other Asia-Pacific countries in March 2013.
After more than six months of searching, the longest-used products in China and the Asia-Pacific region were revealed: the RD series used in the early 1980s at Akzo Nobel Peroxide Co., Ltd. in Tianjin, China, and the Thermo King D series bus air conditioners in Indonesia. These proven products have contributed to the business development of their customers and are a testament to the superior quality of Thermo King products.
The successful application of Thermo King Coaches HVAC in Indonesia
In 1982, PO PAYA in Indonesia selected Thermo King products—the D series bus air conditioners. This was due to Indonesia’s hot climate year-round. Riding on buses without air conditioning under the scorching sun was extremely unbearable for passengers. How to provide a more comfortable riding environment for customers had always been a problem for PO PAYA, one of Indonesia’s top ten bus operators. They then approached Mark IV, the Indonesian distributor for Thermo King. Through evaluation, Mark IV’s extensive experience in bus air conditioning and the superior quality of Thermo King products earned PO PAYA’s trust, leading PO PAYA to ultimately choose Thermo King products for their first bus air conditioning unit.
Thermo King Coaches Hvac’s Successful Application in China
For the past 20 years, Thermo King’s RD series refrigeration units have served Tianjin AkzoNobel Peroxide Co., Ltd. This company, headquartered in the Netherlands, is a world leader in the organic peroxide and organometallic materials industry. In 1994, when Akzo began expanding its business in China and needed to select equipment for transporting peroxides, they unhesitatingly chose Thermo King products. This is because organic peroxides are inherently flammable and explosive, decompose rapidly, and are extremely sensitive to heat, vibration, and friction. The transport of organic peroxides falls under the category of hazardous materials, making temperature control accuracy and reliability the primary considerations for selecting refrigeration units. Therefore, Thermo King, with its industry-leading technology and product quality, won Akzo’s trust and became Akzo’s designer and supplier of hazardous materials transport solutions.

Coaches Hvac China Factory has rapidly risen to prominence by leveraging the advantages of local bus manufacturing, with SONGZ and BUSCLIMA being typical examples.
Ac For Bus Factory has established a differentiated competitive advantage in the global market through three core strengths: full-industry chain integration capabilities, deep customization response, and rapid technology iteration. It excels particularly in modular production, extreme environment adaptability, and cost control.
Ac For Bus Factory has developed extreme environment resistance capabilities covering a full temperature range from -40℃ to 60℃. Through material innovation, system redundancy design, and intelligent thermal management technology, it has achieved stable operation in scenarios such as the high-temperature deserts of Qatar and the extreme cold of Mohe, China, with core performance indicators reaching international leading levels.
From high-temperature vehicles serving the Qatar World Cup to buses operating in the frigid regions of Northern Europe, Ac For Bus Factory has formed a three-in-one extreme environment solution integrating materials, systems, and algorithms. This resistance capability not only supports the global expansion of companies like Yutong and BYD, but also extends comfort to the most demanding climate zones on Earth, even when traditional Coaches HVAC fail at 45℃ due to outdoor unit shutdown. This Chinese solution, through technologies such as liquid cooling and intelligent prediction, extends comfort to the most challenging climate zones.
If you find that Thermo King Coaches HVAC is not suitable for your country’s circumstances, or if you cannot purchase Thermo King products for other reasons, you can choose Bus AC from China, which offers better value and more stable quality. Chinese manufacturers have rapidly risen to prominence by leveraging their domestic bus manufacturing advantages; SONGZ and BUSCLIMA are typical examples.
