Reduced life cycle costs thanks to optimized efficiency
Standard condensate drainage holes in the motor housings
Can be used flexibly in air-conditioning and cooling systems, with application benefits due to direct draining of condensate via optimised lantern design (patented)
High standard of corrosion protection thanks to cataphoretic coating
High worldwide availability of standard motors (according to Wilo specifications) and standard mechanical seals
