Full electric air conditioners and zero emission refrigeration units

The Corunclima AC100TB is a built-in fully DC electric air conditioner designed for engine-powered buses, bringing a transformative cooling solution that breaks away from traditional engine-driven air conditioning systems. Unlike conventional setups that rely on belt-linked mechanical compressors driven by the vehicle engine, this all-electric unit requires no mechanical engine compressor installation at all. It operates independently on DC power, separating cooling performance from engine running status completely, which delivers outstanding economic benefits and stable cooling experience for passenger transport fleets.

And that’s a wrap on RACC EXPO 2026! It was a genuine pleasure to meet so many of our valued clients, trusted partners and new industry friends at the show. This warm reception fuels our passion for continuous innovation and pushes us to keep refining reliable, energy-saving HVAC and refrigeration products for commercial vehicles, medical emergency vehicles, minibuses, shuttle buses and cold-chain transport fleets worldwide.

When every second counts in emergency care, stable and reliable climate control inside the patient compartment is not a convenience — it is a critical part of safe patient care. Corunclima high-capacity full-DC electric ambulance air conditioners are purpose-built to meet the unique, rigorous demands of US EMS operations, delivering consistent cooling performance that traditional engine-driven air conditioning cannot match.
