Conditioners
Air to be conditioned is cooled and dehumidified by contacting Kathene in the conditioner. Heat extracted from the air by Kathene is transferred to the coolant by continuously recirculating the solution through a heat exchanger. Coolant flow through the heat exchanger is fully modulated to control the amount of heat and moisture extracted from the air.
A total of 14 different size conditioners is available, each capable of handling either horizontal or vertical air flow arrangements. The smallest in the series is designed to handle airflows from 750 to 1500 CFM, the largest from 42,000 to 84,000 CFM.

Regenerators
To remove the water extracted from air and keep the Kathene at a fixed concentration, a regenerator is required. Heated Kathene contacts a scavenger air stream and is concentrated by evaporation of water from the solution to the air. Heat flow to the heat exchanger is fully modulated to match the moisture load in the conditioner. The exact amount of moisture absorbed in the conditioner is released in the regenerator to maintain Kathene concentration. A small amount of the concentrated Kathene is transferred back to the conditioner.
Kathabar offers a total of eight different size regenerators which are matched with the conditioners required for a given installation.
If desired, Kathabar regenerators can be located remote from the conditioner. Frequently conditioners are located in the space adjacent to the conditioned space and the regenerator is located in the building utility or boiler room. Since one regenerator can handle numerous conditioners, substantial savings can be achieved when one regenerator unit is used with multiple conditioners. As many as 60 conditioners are in operation with a single regeneration system. Savings are realized in space, in utility piping and in ductwork elimination.
