The operational and technical requirements for temperature control systems in motor vehicles differ from those for other applications. Genuine Thermo King belts are designed to provide the highest levels of performance in your work environment, taking into account stress, temperature and geometry. Belts manufactured by competitors usually only fit Thermo King belts in size but do not provide the same trouble-free performance. Belts from other manufacturers may be “suitable” for your installation, but they are not designed to meet the technical requirements of this installation, including the cross-sectional length, materials, and intended performance.
