sera has developed a cost-efficient system solution specifically aimed at industries with fluctuating, but large requirements of alkaline detergents, such as sodium hydroxide and whose infrastructure is not mature. This solution ensures the safe and efficient preparation of soda lye on the basis of sodium hydroxide (NaOH) in solid form (pellets, flakes, beads or powder) and water.
The basic system consists of a stainless steel preparation tank, an agitator and a special conveyor, which is separate from the preparation tank. The conveyor consists of a hopper and a stainless steel feed screw which transfers the solids into the preparation tank.
This design ensures that the operator is not in the immediate danger zone of the preparation tank in which the solids react exothermically with water.
The preparation tank is available with a capacity of 1000, 2000 or 5000 litres. It is fitted with a level gauge with shut-off valve, a temperature gauge and a tubular safety frame to prevent accidental body contact.
The prepared solution is transferred into a larger storage tank either using a sera transfer pump which is mounted onto the preparation tank or with the help of a sera transfer unit which is separate from the preparation tank.
An optional hopper cover and a special suction device as an additional safety feature are available.
The entire system can be partially automated or integrated into existing process control systems with the help of a PLC.
