Taco offers three bronze casing models and nine flanged cast iron models of its "00" Series of circulators for Load-Match® single-pipe system applications. Taco's Load-Match series circulators have been designed for quiet and efficient operation on Load-Match-designed fan coil heating and cooling systems. All Taco LoadMatch circulators include a removable Integral Flow Check (IFC) to prevent gravity flow and reduce installation costs and an exclusive anti-condensate baffle (ACB) to prevent the build-up of condensate on the motor windings when pumping chilled water.
