Insulated steam-dispersion tubes

Insulated steam-dispersion tubes are a humidification-system option that can reduce wasted energy by up to 85 percent while reducing air-stream heat gain and dispersion-generated condensate production. These improvements are achieved by reducing the thermal conductivity of dispersion tubes with polyvinylidene fluoride (PVDF), an insulating material approved for plenum use (with a fire/smoke index of 0/0) and rated for continuous high-temperature (300°F) operation. PVDF will not absorb water or support microbial growth because of its closed-cell construction, and it will not degrade when exposed to ultraviolet-C germicidal light. The insulation is secured 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, PVDF-insulated dispersion tubes can provide product payback in less than one year for electric humidification systems and in about one-and-a-half years for natural-gas systems.

Automatic condensate pumps

With fully automatic operation, condensate pumps from F.E. Myers Pump Co. move liquid condensate from an appliance to a drain or outlet. The pumps feature a thermoplastic housing that resists high corrosion and impact and an integrated check valve that prevents liquid-condensate backflow.

Energy-recovery units

E-Z-Aire is a makeup-air unit with a high-efficiency heat exchanger that brings in fresh outdoor air while exhausting stale, polluted air. Air is exchanged while heat energy is recovered from exhaust air and transferred to supply air, tempering incoming air.
