DS Series Dry Screw Vacuum Pump

Features
1. Exhaust Path Is Short, Reduce The Deposition Of Reactants.
Compared with other types of dry vacuum pump, DENAIR screw vacuum pump has the shortest gas path in the vacuum pump and that could reduce the contamination of process gas. Screw rotors can act as a powder transmission mechanism, allowing it to perform well even when there is a lot of contamination inside the pump.

2. The Optimal Linear Sealing, Enhancing Pump Performance.
Patented rotor profile provides excellent sealing effects, allowing for larger clearances between rotors. This reduces wear and jamming caused by process contamination.

3.Simple Structure, Low Fault Rate And Easy Maintenance
The screw type vacuum pump consists of a pair of screw rotors and isolation plates, which are not required in different positions. Overhauling the Hanbell dry pump is much easier than other types of dry pumps, resulting in shorter repair times and lower costs.

4.Microcomputer Operation, Remote Monitoring, Considerate Protection
A microprocessor controller offers numerous parameters for monitoring the pump's running status. The pump can be easily operated and monitored through the operation panel. Remote control software helps customers monitor the pump's performance remotely.

Advantages

1.Special cooling liquid cooling, to avoid the cooling water may cause corrosion to the hull. 

2.Mobile operation interface, convenient operation; Display and the actual work of vacuum pump and can be selected to both languages, according to the real close to the customer.

3.Catch the power connector, safe and convenient.

4.The nitrogen gas heater, making the vacuum pump more suitable for CVD, PECVD and other semiconductor technique processes.
5.The control signals and communication signal interface, remote monitoring was carried out on the vacuum. 

Application

1.Health care industry.

2.Lighting industry.

3.A variety of analytical instruments.

4.Electronics, semiconductor industry.

5.Power industry.

6.Refrigeration industry.
