Our AC
receiver driers are compact reliable aftermarket replacements engineered for Koster coaches, fully compatible with R134a refrigerant. These CD-3XXX small aluminum inline units adopt lightweight seamless aluminum housings, supporting cross-reference OE numbers for precise fitment. Built for medium-sized shuttle buses, corporate and tourist shuttle services, frequent stop-and-go and medium passenger loads, they maintain stable moisture capture and impurity filtration. Every drier undergoes strict air-tightness and pressure cycling tests. Manufactured to OEM tolerances for plug-and-play installation, these factory-direct components supply global minibus parts distributors.
