Vacuum systems are used in EPS block molding to create negative pressure, which enhances bead fusion and shortens production cycle times. These systems result in more consistent block structure and lower internal moisture, allowing blocks to cure faster in ambient conditions.
The vacuum tank may be cylindrical, configured in either a vertical or horizontal orientation. It includes an internal steam and water condenser, which supports continuous operation. Water collected in the vacuum system is discharged without requiring a separate pump, contributing to reduced electricity consumption.
This traditional evaporative cooling setup includes key components such as hydrospheres, cooling pools, pumps, and cooling towers to maintain operational temperature and process stability.
