Capsule fill and operation - When placing an order always state

the capsule fill:

Standard capsule - Is marked with 'STD' for operation at

approximately 12°C below steam saturation temperature.

Optionally - The capsule can be supplied for sub-cooled 'SUB'

operation at approximately 24°C below steam saturation

temperature.

For critical applications the 'NTS' fill capsule should be selected

which operates at approximately 4°C below steam saturation

temperature.
