- Advantages
- Retrofit
- Service on demand schedule
- Unisab app for smartphone
- Configurable for both screw compressors and reciprocating compressors, with or without variable-speed drive (VSD), and using any refrigerant
- Built-in regulation of suction pressure, water temperature, discharge pressure, etc.
- Limitations on suction pressure, discharge pressure, motor current, etc.
- Logging of operating history and profiles for effective fault-finding and diagnosis
- Email dispatch in case of alarm or shut down.
The Unisab III systems controller has normal industry-standard communication ports fitted as standard, and therefore does not require additional communication gateways.
