Design Concern

Mechanical Design

The shielding install for protection of mechanism, it can prevent chemical particles to damage bearings.

FFKM O-Ring is available, please contact us for further information.

​

Accessory Design

Shielding Gate Valve also option for heating jacket.

In the hash process, the chemical particles are easy to attach on metal surface, the pumping line may be stuck. The heater provide stable temperature to keep away the particles.

​
Our heating jacket's form is made by "Nano-aerogel super insulation material" with extremely low thermal conductivity for reducing heat loss.

Etched stainless steel foil as the heating element
–Repeatable
•No variation between heaters
–Reliable
•Contact pads is significantly bigger for spot welding
–Uniform temperature
•Heating film covers >40% of heating area!
–Low cost
Less labor intensiv​e
