Head Clamp
Assembly
The Head Clamp Assembly:
1. Carries the hot jet
2. Mechanically accepts the Column Holder
3. Centers the modulator tube (loop “apex”) in the gas jets.
This module is extremely reliable, but field-replacable just in case.
Head Clamp
Assembly
The Head Clamp Assembly:
- Carries the hot jet
- Mechanically accepts the Column Holder
- Centers the modulator tube (loop “apex”) in the gas jets.
This module is extremely reliable, but field-replaceable just in case.
- Estimated MTBF > 7 years
- Field Replaceable Module
- Set-and-Forget Installation
- Can modulate two loops in one Column Holder
("buy one thermal modulator, get one free") - Modulates two parallel Column Sets
- Hot Jet Gas Fitting: 1/4" Swagelok
