01 Overview
Which adsorbents protect refrigeration, glazing and cryogenic equipment?
3 Å molecular sieve keeps refrigeration systems and insulating glass units dry because it adsorbs water while excluding refrigerant and air molecules. Silver Zeolite Hydrogen Getter captures hydrogen released into the vacuum space of cryogenic tanks and pipes.

03 Challenges
What does moisture or hydrogen do to this equipment?
Four failure modes the adsorbent prevents.
Ice blockage
Moisture freezes at the expansion valve and stops refrigerant flow.
Acid and corrosion
Water reacts with refrigerant and lubricant to form acids.
Fogged glazing
Moisture in an insulating glass unit condenses between panes.
Vacuum loss
Hydrogen in a cryogenic vessel’s vacuum space raises boil-off.

08 From our plant
What you receive
The adsorbent, the packing and the plant it ships from.
Why is 3 Å sieve used in refrigerant driers?
Water enters the 3 Å pore while refrigerant molecules stay outside.
Which molecular sieve is used in insulating glass?
3A Molecular Sieve beads in the spacer bars keep the gas space dry.
Does the silver zeolite getter need activation?
No. It is supplied ready to use, is non-flammable and withstands up to 500 °C.
Which refrigerants is the sieve used with?
R-134a and other HFCs, and hydrocarbon refrigerants such as butane.
