The AC compressor is the heart of your bus air conditioning system—and with Caseter, that heart is built for endurance. We provide heavy-duty compressors compatible with a wide range of buses, from low-floor city models to long-haul coaches.

Our compressors, including TM16, TM21, TM31 and FK40/50 series, are tested under high thermal and vibration conditions to ensure long-lasting performance. Caseter’s compressor models deliver high displacement rates with optimal oil circulation, resulting in faster cooling and better fuel efficiency.

Each unit is precision-machined and available with matching clutches and mounting brackets, ensuring easy integration and minimal downtime for fleet operators.
