The new Condair dehumidifier range comprehensively covers both desiccant and condensing technologies with extensive standard capacities from 0.5kg/h to 182kg/h (@20°C/60%RH). Custom units are also available, which are capable of providing greater dehumidification or operating under specific or extreme environmental conditions required by an application.

Condair desiccant dehumidifiers use a silica-coated sorption rotor to absorb moisture from the air. This type of technology is said to be ideal for low temperature conditions or applications that require very dry air, below 50%RH. The dehumidifier’s sorption rotor is regenerated with a heated airflow and the wet, hot air is vented externally. As standard, electrical heat exchangers are used for this regeneration process but gas-fired, steam or hot-water heat exchangers can also be used, either alongside the electrical heater or instead of it, to reduce energy and operating costs.

The desiccant dehumidifiers, from Condair, are designed to allow additional modules to be seamlessly attached on either the process or regeneration airflows. These modules provide pre or post-cooling, post-heating or air-cooled condensation removal. Being able to customise the system with these modules allows air to be delivered to an area or room at a precise temperature as well as the correct humidity. The air-cooled condensation module removes the need for external venting of the wet regeneration airflow, making the system even more flexible in its operation.
