Sinergi has a manufacturing Ammonium Chloride Processing Unit (NH4CL) located in the Cilegon industrial area, precisely in the PT Timah Industri area. The Sinergi Ammonium Chloride Processing Unit consists of 7 parts, namely the holding tank, boiler, heat exchanger, evaporator, crystallization unit, packaging, and water treatment. The product of Ammonium Chloride Processing is in the form of solids or concentrated solutions, for example salt obtained from saturated brines (an example of a purification process). The evaporator turns water into steam, leaving mineral residue inside the evaporator. This vapor condenses into desalted water. In the cooling system, the cooling effect is obtained from the absorption of heat by the rapidly evaporating coolant.
