Wirtz – Conbro Fully Automatic Acid Mixing System – 15 GPM

Conbro is wholly owned and operated within The Wirtz Group of Companies and has been a market leader in lead acid battery formation equipment design and manufacturing for over 30 years. Different specific gravity sulfuric acid is used in various operations during the lead acid battery manufacturing process. The Conbro fully automatic acid mixing system will monitor, mix and maintain specific levels of multiple different specific gravity acids. This is all done automatically.

The ConBro Acid Mixing System includes a main control panel, a solenoid panel, a mixing unit including support, heat exchanger, mix train and controls, a concentrated acid pump, the reclaim and product tank mix pumps, and adequate pipe fittings and valves, and level sensors, from the mixing unit to the product and reclaim tanks. This system does not include the cooling piping, piping from the mixing unit to the points of use in the plant, any building modifications, installation, start up, or freight. The system is controlled by a PLC with PanelView operator interface for inputting and reading data. The main units are pressure tested at our factory. We will provide a color-coded layout drawing that clearly defines the responsibilities of Wirtz and customer for the scope of supply.

General Operation:

  • Stored concentrated acid is pumped to the mix stand assembly, where either water or diluted acid from the reclaim tank is mixed with the concentrated acid to produce a specified specific gravity
  • The product acid is passed through a heat exchanger to remove heat from the reaction, and a density cell is used to confirm and make minor recipe adjustments to achieve the specified specific gravity.
  • The product acid is pumped to any one of a number of product tanks where it is stored until it is used.

Benefits of a Conbro Washer and Dryer:

Fully automatic (PLC controlled) with tank level sensors.

Accurate and repeatable acid mixing using a unique density cell and recirculation loop.

Heat exchanger to keep acid temperature during mixing lower.

Can have unlimited product acid tanks and recipes.

Acid resistant construction for longevity of equipment
