Kathabar SP

The SP series offers a high-efficiency, vertical airflow design in a factory-packaged, plug-and-play system. This system requires only the utilities at your plant and power to a single point. Ready-to-use SP units are ideal for small applications such as waterworks, casting applications, pharmaceutical drying rooms and filling areas.


Small, package conditioner/regenerator

  • A combined conditioner and regenerator on a single skid for easy installation
  • Vertical discharge, with available airflows ranging from 1,500 CFM to 20,000 CFM
  • Industrial fiberglass (FRP) platform base with factory-mounted, desiccant solution pumps and heat exchangers
  • Wiring, controls, and desiccant solution piping factory completed and tested
  • Horizontal, end-suction desiccant solution pumps with seal-less, magnetically coupled motors

The SP liquid desiccant systems are designed for airflow capacities from 1500 CFM to 20,000 CFM.

The smaller SP sizes (SP240-600) are compact skid-mounted units with conditioner and regenerator towers that share a sump and offer our smallest footprint for a complete dehumidification system.

The larger SP sizes (SP800-1600) offer a FV conditioner of the same size paired with a FP 6 on one skid, with all components mounted, and the interconnecting desiccant solution piping and wiring completed at the factory.
