DX Systems
Direct expansion cooling solutions engineered for commercial performance — designed and installed by CVAC International.
About This Service
Direct Expansion (DX) systems provide efficient, flexible cooling for commercial spaces where centralised chilled water plant is not viable. CVAC International designs and installs DX systems including packaged rooftop units, split DX, and close control units. We work from first principles — calculating cooling loads, selecting equipment, and designing refrigerant pipework to manufacturer and F-Gas requirements.
Service Detail
How DX Systems Work
DX systems operate by expanding refrigerant directly within the indoor unit’s cooling coil, allowing heat to be absorbed from the air and transferred to the outdoor condenser.
