Note, Capsule Fill and Operation - When placing an order always state capsule fill:
Standard Capsule - Is marked with 'STD' or 'E' for operation at approximately 12°C below steam saturation temperature.
Optionally - The capsule can be supplied for sub-cooled 'SUB' or 'F' operation at approximately 24°C below steam saturation temperature.
For critical applications the 'NTS' or 'G fill capsule should be selected which operates at approximately 4°C below steam saturation temperature.
