SAVE WATER
› Calculated at an assumed average of six operating hours a day on 200 business days a year, a rotary
evaporator (50 l/h) cooled with tap water consumes 60,000 liters of water per year. That amount can
be saved by using a recirculating chiller, not only protecting the environment, but also reducing
operating costs.
SAVE ENERGY
› IKA has succeeded in achieving energy savings of up to 60 % in comparison to competitors' devices,
simply by the afore-mentioned innovations of the recirculating chiller, particularly the speed-controlled
compressor.
POWER CONSUMPTION – A COMPETITIVE ANALYSIS
› Example: Energy consumption of a chiller in a standard distillation of a rotary evaporator (500 ml water in
an 1 liter evaporating flask). Water bath temperature + 60 °C, pressure 70 mbar.
When comparing the average power consumption of the chiller in neutral/idle mode (rotary evaporator is
turned off), the RC 2 from IKA clearly runs more eciently in comparison to the competition (Figure 1).
When considering energy consumption over an entire day, the eciency has an even greater impact. The
on-demand circulation chiller from IKA reduces its power to a minimum, adapting to the actually required
cooling performance. Figure 2 shows that the IKA RC 2 in comparison to competitor 1 consumes less than
one-third of the energy. › Figure 3 shows the mechanism of our on-demand recirculating chiller (red) in comparison to an unreg-
ulated chiller (blue). Depicted is an 8-hour work day, with four 500 ml (H

O) distillation runs. It's easy to
recognize the overall lower power demand when in idle mode, as well as the adjustment of the cooling
performance during the distillation process.
