Drier
Efficient Drying Solutions for Galvanizing
In the hot-dip galvanizing process, effective drying and preheating of metal components are essential for achieving a high-quality zinc coating. At Gunatit Builders, we offer advanced Dryer Systems that prepare materials before they enter the furnace for zinc coating. Our dryers minimize zinc splashing, reduce thermal shock, and optimize furnace operation times, resulting in a smoother and more efficient galvanizing process.
Our dryers utilize excess heat from the furnace, which is typically vented to the chimney. By recirculating these flue gases, the system eliminates the need for additional energy, making it both cost-effective and eco-friendly.
Older dryer designs often directed combustion emissions into a pit, which led to low efficiency and issues such as salt “burns.” Our modern dryers, however, use advanced chamber or tunnel designs to preheat materials at high temperatures, enhancing conditions for a protective zinc layer and improving the speed and quality of the galvanizing process.
Types of Dryers Offered by Gunatit Builders
Re-Circulating Air Dryer
Hot Plate (Conventional Type Dryer)
Re-Circulating Air Dryer
Built from premium carbon steel and insulated to prevent heat loss, our Re-Circulating Air Dryer efficiently transfers furnace heat to the dryer. It uses a blower to recirculate hot air, and the flue ducts are lined with insulation and finished with epoxy aluminum paint for corrosion resistance. The design is easy to maintain and clean, ensuring reliable performance.
Hot Plate (Conventional Type Dryer)
The Hot Plate Dryer is a conventional yet effective solution for drying and preheating materials before galvanizing. It ensures that fluxing salts adhere to the metal surface, minimizing the risk of zinc splashes. The system uses excess furnace heat redirected from the chimney, providing a cost-effective heating process without additional energy.
