February 28, 2007—DRI-STEEM has introduced insulated tubes as a humidification system option that reduces wasted energy by up to 85% while significantly reducing airstream heat gain and dispersion-generated condensate production, according to the company.
These improvements, explains DRI-STEEM, are achieved by reducing the thermal conductivity of dispersion tubes with polyvinylidene fluoride (PVDF), a robust insulating material recently approved for plenum use (with a fire/smoke index of 0/0), and rated for continuous high-temperature (300 °F) operation.
The PVDF insulating material will not absorb water or support microbial growth, due to its closed-cell construction, and it will not degrade when exposed to UVC germicidal light. Advanced manufacturing processes ensure that the insulation is secured firmly to the dispersion tubes and will not loosen or shift.
Available as an option for new and existing Ultra-sorb and Rapid-sorb steam dispersion systems, the energy savings from DRI-STEEM’s PVDF-insulated dispersion tubes can provide product payback in less than one year for electric humidification systems and in about 1.5 years for natural gas systems.
