When a vessel moves through the water, acoustic noise is created and is known as a boundary layer. This noise layer can cause errors with acoustic devices. By measuring speed through water (STW) farther away from the keel, the DS-85 penetrates through this noise and boundary layer resulting in a mor

PLP is Galletti’s new range of air-cooled packaged chillers and heat pumps for outdoor installation equipped with a modulating scroll compressor driven by an inverter and characterized by the use of R290 refrigerant.
