Unique features
FLEXIBLE SENSOR OPTIONS
The MiniBlue® is available with a range of sensing options, giving you the flexibility to tailor its operation to your HVAC system:
CR Plug (X87-500): Converts your MiniBlue® into a continuously running pump, ideal for environments with constant condensate production. The pump activates as soon as your HVAC system is switched on, ensuring continuous drainage performance.
Temperature Sensor (X87-504): Activates the pump when a 5°C temperature difference is detected between the air inlet and outlet. This ensures immediate and uninterrupted condensate removal, delivering efficient and responsive operation.
*Reservoir option available with the MiniBlue R (X87-509)
FLEXIBLE INSTALLATION
The MiniBlue pump offers flexible installation with the ability to be mounted in any orientation without affecting performance (8m/ 23ft away from the unit). Its compact design and versatile mounting options allow for seamless integration into tight spaces or unconventional setups, ensuring reliable operation across a wide range of applications.
OPERATES WHISPER-QUIETLY
The MiniBlue pump is designed for whisper-quiet operation, making it ideal for sound-sensitive environments. Utilising BlueDiamond’s advanced rotary diaphragm technology, it minimises vibrations and sound while maintaining a reliable performance. Its efficient, valveless design ensures smooth, consistent flow with minimal maintenance, making it a top choice for straight-forward condensate removal applications.
TRUSTED RELIABILITY
