Customized to your footprint and optimized to your exothermic reaction
Our curing chambers and components are sized to optimize the cycle times while obtaining the best results for crystallization, porosity, and moisture. The design of our system is modular and scalable. We can customize it to match your plates, pallet sizes, and factory foot print. Airflow is from one side to the other. Goals are to optimize the bond between paste and grid and to create the pathways for full utilization of the active material.
Wirtz Technology:
The parameters we control for every cycle are:
The curing chambers are designed to control the humidity and the temperature during exothermic reaction phase to oxidize the metallic lead and bond the paste to the grid. Curing takes place at between 40 to 80 oC and at 90 to 100% RH. Cycles range from 16 to 24 hours depending on your specifications.
The drying cycle is to remove the humidity from the plate as fast as possible but without burning the plate or collapsing the porosity. Drying temperatures do not exceed 75 oC and with low RH. Cycles range from 10 to 24 hours depending on your specifications.
Constructed of stainless steel interior and carbon steel exterior with 4 inches of insulation. A skeleton structure is used to reinforce chamber walls and roof. The design allows for additional chambers to be added in a modular assembly utilizing an existing side wall as a common wall. The chamber is designed to hold 12 pallets of plates, 3 high by 4 deep, by 1 wide.
The standard curing chamber includes an automatic fabric roll up door. An individual electric panel type nema 12 is located on the front of the oven. The Model AC143 Curing Chamber is capable of curing and drying for both tetrabasic and tribasic crystals in less time due to enhanced air handling and increased air volume. The chamber design includes full side wall air plenums on both side walls to control air flow across the single wide pallets of plates which provides consistent curing throughout the chamber, and from batch to batch.
All functions of the chamber are controlled by a PLC, sized for up to 4 cure chambers.
A variable adjustable exhaust damper automatically controls chamber humidity to programmed preset limits.
A supply fan automatically adds outside air for cooling to control peak chamber temperatures due to variations in the exothermic reactions.
Atomized water is introduced for humidification for tribasic applications.
Steam humidification is optional for high temperature tetrabasic applications
*These are very general specification and will change based on the exact configuration of the system that is ordered.
