💡 What triggers thermal glass capsules in automated suppression systems? Heat conduction breaks the fluid seal once indoor temperatures cross the tested threshold.
- Thermal stress fractures the silica tube to release flow fast
- Flange mating surfaces grip tight without cross stripping during swaps
- Gasket compression handles steady municipal pressure drops easily
