The x10¹ Pa ultimate pressure specification meets a wide range of research and development needs. The all-stainless steel exterior has an attractive hairline finish. The vacuum pump can be connected to suit specific installation locations, allowing effective use of spaces on top of the experiment table or other fixtures.

DN-30S

Vacuum pump for DN-30S (example)
TSW-100N

The casters improve maneuverability
even in tight spaces.

Features

■High vacuum ... ultimate pressure: x10¹Pa
Connecting the oil-sealed rotary vacuum pump creates a powerful vacuum. The DN-30S provides clean heat treatment in a vacuum chamber with remarkably low leakage.

■Measurements of vacuum degree
The structure is equipped with a gauge port ( φ15 mm) that allows the attachment of a Pirani vacuum gauge sensor to confirm the vacuum degree (Pa value), a value that can't be read by a Bourdon-tube vacuum gauge.

■All-stainless steel specifications
The vacuum chamber is made of SUS304 stainless steel. Individual vacuum components such as valves and vacuum pipes are made of SUS304 and 316. For improved strength and corrosion resistance, Teflon, Viton and silicone are used as sealing materials.

■Programmable functions
The programmable controller provides two program patterns for programmed control, each with ten segments.

■Easy temperature control
The controller automatically sets the ideal PID value for processing temperatures for easy, reliable temperature control inside the vacuum chamber.

■Modular control circuit
The control circuit comprises several module panels that can be individually removed for easy component replacement and repairs.

■Safety and Product Maintenance

1. The temperature controller and overheating prevention device each provides comprehensive safety measures, including a self-diagnosis function and double overheating prevention functions.

2. Made of tempered glass, the observation window is designed to allow clear viewing of the entire structure. For even greater safety, a protective cover made of clear resin overlays the tempered glass window.

Applications

The DN-30S is primarily used in a wide range of vacuum drying experiments involving electrical and electronic components, electronic materials, metals, ceramics, new materials, and so forth, as well as in research and development.
