Tubular desiccators provide protection against corrosion, dampness and contamination in electronic, electrical, optical, electro-optical, telecommunications, computer equipment etc. These desiccators do not incorporate a humidity indicator; however they can be fitted to a separate humidity indicator or mounting plug for panel mounting onto equipment.
A powerful adsorbing agent (either molecular sieve or silica gel) 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 sensitive applications. It is most suitable for applications where equipment or enclosures may be subject to operation at low temperatures and water vapor condensation must not occur.
