Self Build Kits ASU

Isotherm's range of ASU fridges and freezers use a patented intelligent energy management system in which the holding plate is charged using surplus energy from the alternator whilst the engine is running. Designed for use in sailing yachts in which battery energy is at a premium, the charge is released when needed.  If you need any assistance then please contact our Sales Team.
