Hitachi 2000 mainframe cooling system manufactured in 1992. Comprises of a main control and pumping unit and two refrigerated air handlers. The main input is 3 phase 200v 63A  I believe. and comprises two pumps with magnetic bearings, stainless header tank, and stainless fittings throughout. A large computerised control panel sits at the front. The refrigerator units have a variable speed compressor with synthesised ac frequency from a dc rectifier so could be used from a single phase source. Both units appear to be still fully gassed up. A massive copper radiator with scroll fans dissipates the heat out the top of the units. The whole system was beautifully manufactured to a very high spec as it had to be ultra reliable. Has been stored in the dry for 25 years. Will need a pickup truck or high top lwb transit/sprinter to transport. Have forklift to load. Located in North Cornwall, collection only.
