The new generation of pump core

The new generation of the Si-20 pump core has been significantly reduced in size without compromising the top performance of Sauermann's patented oscillating piston technology, which has proven its extremely high efficiency for over 12 years. This results in a flow rate of up to 20 liters per hour, unique for this format.

Refrigerant leaks contribute to climate change. Refrigerants with a lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with a higher global warming potential (GWP). A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming than 1 kg of CO2 over a 100-year period, proportional to the refrigerant's GWP value. Do not perform any work on the refrigerant circuit or disassemble the unit – always consult qualified personnel.
