Variable Speed Delta T Circulators
October 26, 2009
Variable Speed Delta-T circulators by Taco combine a microprocessor-based variable speed differential controller with the reliability of its 00 cartridge circulators.

Variable Speed Delta-T circulators by Taco combine a microprocessor-based variable speed differential controller with the reliability and convenience of Taco’s 00® cartridge circulators. Simply dial in the design delta-T of the system or zone (from 5 - 50°F). The circulator automatically adjusts its performance to match the system’s ideal Btu/hr. output, while reducing fuel consumption 4-5% and eliminating velocity noise.
