Every bus model has different cooling demands — and Caseter delivers custom-engineered HVAC systems to match. Our R&D team works with OEMs to build units that integrate perfectly with your design and performance needs.

End-to-End Customization

From cooling capacity to physical layout, Caseter offers modular system design, software-level control, and voltage compatibility (24V/48V/72V), tailored for different bus types and markets.

OEM Partnership Experience

We support OEMs across Asia, Europe, and Latin America, providing custom HVAC units for school buses, articulated city buses, and electric shuttles.

Testing and Compliance

Every custom unit undergoes climate chamber testing, vibration simulation, and regulatory compliance validation (CE, ISO, etc.).
