Remote breather desiccators provide protection against corrosion, dampness and humidity contamination in electronic, electrical, optical, electro-optic, telecommunications, computer equipment etc. These remote breathers can incorporate a humidity indicator, which monitors saturation and signals when desiccant replacement is required.
The humidity indicator is blue when the desiccant is dry and turns pink when the maximum amount of moisture has been adsorbed.
A powerful adsorbing agent (either silica gel or molecular sieves) reduces the existing or incoming moisture to acceptable levels. The use of molecular sieve desiccant is recommended when the equipment may be subject to immediate failure as a result of water vapour condensation. The molecular sieve desiccant maintains an ultra low relative humidity for extremely moisture sensitive applications. It is most suitable for applications where equipment or enclosures maybe subject to operation at low temperatures and water vapour condensation must not occur.
