For special applications, cylindrical vessels can be supplied with a jacket for heating or cooling. Jacket is sealed to the vessel with Viton 'O' ring and other sealing compositions. The seal prevents high stresses between vessel and jacket by allowing the movement flexibility between two due to thermal expansion.
Glass Jackets
Glass Jacket can be used for a maximum operating pressure of 0.5 bar and a maximum operation temperature of 130ºC in jacket. The temperature difference between jacket & vessel should not exceed 120°C.
