Description
The Wilo-BAC series is specifically designed for safe integration into Chillers & Heat Pumps, including new generations using the eco-friendly R290 refrigerant. For that purpose, the BAC50 was tested by an external laboratory to verify compliance with the requirements of clauses 22.116 and 22.117 of IEC 60335-2-40:2022.
Its Victaulic ports make the connection quick and easy. It is available in different power rates with high interchangeability, providing a high flexibility of usage. Designed specifically for continuous operation, the pump also offers a long service life thanks to its corrosion-resistant materials or coatings and maintenance-free roller bearings.
