Technical Features
Vacuum System
The system incorporates frequency conversion technology to operate the Roots pump under atmospheric pressure startup conditions, enhancing operational flexibility and energy efficiency.
Multiple vacuum pump connections can be designed into the equipment, enabling simultaneous evacuation via several devices to accelerate the vacuum-drawing process.
High-efficiency condensers and buffer devices are installed in the vacuum pipeline to ensure stable and reliable operation while preventing backflow or contamination.
Smoke Extraction Device
A smoke collection system is integrated to significantly reduce lampblack emissions, improving environmental compliance and workplace safety.
Electrical Control
Siemens PLC (Programmable Logic Controller) is employed for precise, automated, and reliable control of the entire system.
Additional Features
Precision-machined components and the use of internationally renowned brands ensure high mechanical and electrical reliability, minimizing maintenance costs and guaranteeing consistent operational efficiency.
