DriTec® 4000i desiccant dehumidifier offers outstanding cold weather performance

By Dri-Eaz   


March 9, 2015 - This winter’s snowstorms and icy blasts have wreaked havoc for many property owners. The Dri-Eaz® DriTec desiccant now provides a solution for restorers struggling to dry buildings in less-than-ideal conditions. The DriTec produces very dry air in cold environments, outperforming LGRs and traditional refrigerant dehumidifiers by a significant margin.

The extremely dry air produced by the DriTec makes it especially valuable for drying dense materials like hardwoods, plaster and concrete.
The unit can also help maintain drying rates on the second half of restorative drying jobs, when traditional LGR dehumidifiers typically pull less water as the humidity decreases.

“When humidity drops below 30 or 40%, the performance of refrigerant dehumidifiers really starts to flatten out,” notes Brandon Burton, Director of Technical Training. “This reduced performance can easily add a day or two to the drying process. Restorers can greatly benefit from adding the DriTec to their drying system.”

The DriTec is highly compact, making it easy to include on the truck – it’s one-third smaller than other portable desiccants and it can fit in the same space as an LGR dehumidifier.

One of the DriTec’s unique features is its dual thermostat control, which allows the user to set both a maximum and minimum humidity setpoint. “There’s a strong perception in the market that desiccants can dry materials like hardwoods too quickly and cause damage,” notes John Otero, Director of Restoration Products. “By allowing the customer to control both minimum and maximum setpoints, the DriTec’s humidistat system will help eliminate this concern.”

The unit’s intelligent controls use internal sensors to monitor system operations and optimize performance in all conditions. The control also displays real-time temperature and relative humidity information, and – an industry first – it displays an average 24-hour water removal rate.
