The Dometic Vector Turbo Unit completely revolutionized self-contained boat air conditioning (cooling and heating) with patented innovations in marine air conditioning system design. The rust-free molded composite drain pan has three drains for the rapid removal of condensate water. The drain pan has a small footprint for installation flexibility. A vibration-isolation mounting system results in significantly quieter, virtually vibration-free performance. The enclosed blower motor eliminates overhang for reduced depth. The Turbo series was specifically engineered to harness and maximize the impressive performance of R-410A, a proven and environmentally safe refrigerant gas. The optional Turbo sound cover provides up to 50% further noise reduction. This compact, easy to install sound cover completely encases the compressor to provide a 3- to 5-dB reduction in noise.
