SAUERMANN Si-27 - Quiet mini condensate pump for air conditioning systems | The alternative to the Si-30 condensate pump |

Si-27 - Successor to the Si-2750 and proven like the Si-30!

A technology for every requirement.

The Si-27 is suitable for air conditioning units up to 20 kW - 6700 Btu - 5.6 RT. The technology of the oscillating piston pump was specially developed for draining condensate from these units.
The Si-27 works reliably under all ambient conditions with extremely low running noise, regardless of the amount of condensate to be drained. It is identical in construction to the Si-30 - only the scope of delivery is adapted.

Advantages:

• Patented oscillating piston technology
  - Powerful: Only one pump for all air conditioners up to 20 kW 67000 Btu - 5.6 RT
  - Insensitive to dirt under all ambient conditions. Small particles are flushed out.
  - Proven reliability
• Low noise
  - Very quiet in operation (20 dBA, tested by an independent laboratory)
  - The performance of the air conditioner and the amount of condensate to be discharged have no influence on the running noise of the pump.
• Easy installation
  - Compact design
  - Special bracket for mounting the pump on the wall, on a pipe or suspended.
  - The cable with detachable plug facilitates maintenance work and replacement of the pump.
  - Safety contact
• Energy-saving
  - Increased performance reduces the pump's switch-on times and therefore power consumption.

Main features:

• Low space requirement
• Low running noise: 20dBA
