1. Advanced Humidity Control

2. Energy Efficient Desiccant Based Dehumidification New class of desiccants that regenerate at lower temperatures Now able to utilize DX condenser heat for regeneration. Unlike traditional high temp regeneration (gas or electric) we are able to deliver low dew points with much less energy. This technology has opened up commercial markets for desiccant systems.
