Manila Water Company Inc., one of the Philippines’ largest water service providers, faced rising operational costs due to outdated blower units in three of its STPs. The issues included:
- Excessive energy consumption
- Limited availability of spare parts
- Inaccessible or unreliable service support
These challenges made the existing units unsustainable, prompting the company to seek a more efficient and cost-effective alternative.
The Solution: Robuschi Robox Screw Technology
Robuschi proposed a targeted replacement strategy:
- Two units replaced with Robuschi WS 85 Robox oil-free screw compressors
- One unit replaced with a Robuschi WS 105 CDL Robox oil-free screw blower
