GREENWARE DRYER
The Greenware Dryer is a programmable chamber drying system for sanitary ware after casting, combining controlled heating, humidification, air circulation and moisture extraction in a product-specific drying cycle. Coordinated control of temperature, relative humidity and airflow supports uniform moisture removal, repeatable drying conditions and an efficient transition from casting to downstream production.

Rotating Conical Air Circulation Units
High-volume turbo fans feed slowly rotating conical distributors that continuously redirect conditioned air throughout the chamber. Reference UNIMAK units provide 22,000 m³/h airflow per ACU, with the number of units configured according to chamber size.
Closed-Loop Moisture & Pressure Management
Servo-controlled fresh-air and exhaust dampers operate together with variable-speed extraction and humidity feedback. The coordinated control regulates moisture removal while maintaining stable internal chamber pressure throughout the programmed cycle.
Three-Curve Recipe Automation
PLC/PID control coordinates dedicated set curves for temperature, relative humidity and air-circulation fan speed. Product recipes can be stored, edited graphically and compared against actual process curves during operation.
Modulating Heating with Integrated Safety Control
The heating aggregate regulates burner output and the fresh/hot-air balance according to the drying curve. Temperature monitoring, differential-pressure sensing and automatic burner shutdown protect the process during abnormal airflow or overheating conditions.
In-Chamber Thermal Distribution
Hot-air distribution ducts are positioned inside the dryer so that thermal losses from the duct surfaces remain within the controlled chamber. Insulated enclosure panels further support stable operating conditions and reduced unnecessary heat loss.
Independent Sectional Loading Doors
Sectional doors operate independently, allowing selected chamber sections to be accessed without opening the full dryer. Multiple doors can also be opened together for faster trolley handling and rapid chamber cooling when required.
