Condensate return units for systems up to 90,000 sq. Ft. EDR. The CB is designed for systems with low return lines. This condensate unit features the B-35 pumps which has a sudion inducer to create a positive pressure at the centrifugal impeller thus guaranteeing low NPSH pump requirements. The CB units require only 2′ NPSH and can pump condensate up to 210°F (99°C) at sea level. Series CB units include cast iron receivers, sized from 6 – 250 gallon (Z3 – 946 liters). The cast iron receiver includes a 20 year warranty against corrosion. CB units are available in either simplex or duplex design. Receivers have a low height NPT inlet for easy return line piping and a separate NPT overflow that can be used as a secondary vent. All simplex units include a two pole float switch. Duplex units include float switches (a mechanical alternator is available). All pumps are bronze fitted with bronze case wear rings and stainless steel shafts.
