Kathabar FV conditioners
The Kathabar FV design offers the most efficient and effective latent and sensible performance, lowest unit air pressure drop, smallest footprint, and lowest equipment cost in our range.
Kathabar FH conditioners
The Kathabar FH design is ideal for applications with space and height limitations that prohibit the use of the FV series.
Kathabar FP regenerators
These packed-tower regenerators can be used with all Kathabar FV and FH conditioners. They are available in a range of sizes, with moisture removal capacities from 120 lb/hr to 6000 lb/hr.
Kathabar SP system
A high-efficiency plug-and-play system with vertical airflow discharge. Designed for applications with airflow capacities from 1,500 CFM to 20,000 CFM.
Temperature and humidity control for your application
Flexible, customisable Alfa Laval Kathabar solutions are perfect for a wide range of applications that require precise temperature and humidity control, including pharmaceutical, confectionery, brewing, hospital facilities, commercial bakeries, cold storage, gelatin, and meat processing, among others. Let us design your perfect solution.
How it works
Alfa Laval Kathabar liquid desiccant dehumidification systems use Kathene, a non-toxic solution composed of lithium chloride salt and water, to absorb moisture from the air. Kathene does not vaporize and is not degraded by common airborne contaminants.
Kathene’s absorbency depends on the temperature and concentration of the solution, which can be adjusted to create any relative humidity level between 18% and 80%. For a given Kathene concentration, lower solution temperatures enable the conditioner to deliver cooler, dryer air.
The basic elements of an Alfa Laval Kathabar system are illustrated below.
Kathene in the conditioner cools and dehumidifies air on contact. The continuous circulation of Kathene through a heat exchanger extracts energy from the air and transfers it to a coolant. By controlling the flow of coolant through the heat exchanger, the amount of heat extracted by the Alfa Laval Kathabar dehumidifier can be modulated to match the load.
As moisture is absorbed by the Kathene solution in the conditioner the solution becomes diluted. As the level in the conditioner rises, a portion of the solution is pumped to the regenerator, where the moisture is driven back out of the desiccant with heat. The Kathene is heated in the regenerator with the heat exchanger, creating an area of high vapor pressure. The Kathene meets the scavenger airstream and moisture is released from the desiccant into the air stream to be exhausted outside. This process is continuous, and constantly modulating the cooling and heating provides precise conditions for the process.
