Temperature switch and temperature protection switch
By default, each diffusion pump is operated with 2 temperature switches. Both switches must be ordered separately.
- The temperature switch signals to the controller that the operating temperature of the oil has been reached. Depending on the particular oil used, this temperature ranges between 180 and 220 °C.
- The temperature protection switch triggers when the maximum allowed temperature is reached. The controller interrupts the power supply to the heater plate. The switch needs to be reset with the push button.
Temperature measurement DN 320 – DN 1000
Temperature measurement at the pump base as an alternative to the mechanical temperature switch
- PT100 with bayonet lock for quick replacement during operation
- Protective feedthrough with bayonet lock
- Optional temperature transmitter with display, signal 4-20 mA
Oil condenser
Reduces the oil consumption of diffusion pumps by condensing oil vapors between the pump and the forevacuum pump.
- Water-cooled housing
- Replaceable condensation inserts
- Long service life
- Proven design
- Lower operating costs of the diffusion pump
- Available in 2 sizes, DN 63 ISO-K and DN 160 ISO-K
- No impact on pumpdown time
- Especially suitable for processes with high gas throughput
Refilling device
Device designed for HSR diffusion pumps
- For refilling operating media during operation
- Oil is pumped directly from the container into the diffusion pump
- Optical level control at glass tube
