The MEGA-PURE Automatic Collection System is designed to collect water from the MEGA-PURE stills and control their operation and store up to 45 liters of Type II distilled water. All glass design with glass inlet and outlet tubing. The ACS is preset to shut off the power to the heaters and the water supply to the MEGA-PURE still after the bottle has collected approximately 45 liters. When the purified water supply has been depleted to approximately 38 liters, the system will automatically restart the water still and refill the collection system. When setting up a MEGA-PURE still with the ACS...Catalog No.: D3121-1 | D3121-2 | D3121-3
Designed for durability and consistent quality, the Classic Still was originally designed over 100 years ago, and has withstood all the tests of time. A low water cut-off prevents still burnout in the event of feedwater interruption. Manufactured from copper and bronze, with a coating of pure tin. Pure tin is used due to its inert properties against the corrosive nature of pure water. Pure tin will also not leach any contaminants into the water. Feedwater preheated in condenser conserves energy. Double-walled boiler conserves electricity. Inert pure tin water pathways will assure product...Catalog No.: | D3140-8
