Introduction Core Components Product Features Parameters & Pumping Speed Curve Diagram Product Structure Diagram Application Scenarios

Introduction

The core components of the DPH vacuum unit are screw pumps and Roots pumps, representing a model of efficient integration in modern industrial vacuum technology. By intelligently combining a dry screw vacuum pump as the backing pump with a Roots vacuum pump, it fully leverages the advantages of both, delivering high pumping speed, high energy efficiency and clean vacuum performance over a wider pressure range.
The complete unit features core strengths including oil-free cleanliness, low noise, energy saving, stability and durability. It is widely used in high-end manufacturing sectors such as lithium battery new energy, semiconductor manufacturing, photovoltaic industry and precision processing, providing one-stop, efficient and reliable vacuum solutions for large-capacity, high-precision vacuum processes.

Product Features

Wide pumping speed range

The pumping speed ranges from 1000 m³/h to 7000 m³/h. The Roots pump and screw pump work in a scientifically coordinated manner: the screw pump quickly completes rough pumping and pressure establishment, while the Roots pump accurately boosts pressure and improves efficiency, achieving dual breakthroughs in pumping speed and vacuum degree.The ultimate vacuum can reach below 0.1 Pa, easily adapting to the vacuum requirements of different chambers and production lines with varying capacities, and greatly shortening the process cycle.

Intelligent interaction hub, control at your fingertips

Equipped with a high-resolution touch screen, it creates an intuitive graphical human-machine interface. The operation logic is clear and concise, with key operating parameters visible at a glance. The system supports real-time panoramic monitoring of the vacuum unit status, and immediately triggers multi-stage audible and visual alarms with precise positioning in the event of an abnormality, realizing intelligent management of the whole process from interaction to operation and maintenance.

Multi-mode intelligence, balanced efficiency and performance

One system, multiple efficiencies. Intelligent operation schemes are tailored for different scenarios such as high-efficiency production, green energy conservation, and stable heavy-duty tasks. With simple selection, an optimal balance can be achieved among extreme efficiency, economic cost, and exceptional reliability, empowering flexible and diverse production strategies.

Simplify complexity for easy maintenance

Simplified design of water cooling channels and water cooling control; the quick-connect cooling system and fully standardized interface design enable rapid assembly, disassembly and replacement of the cooling water circuits.

Standardized interface

Multi-protocol compatible expansion for easy communication and control with external equipment: RS232/485, Profibus, EtherCAT and Ethernet are available as options.
