Kaeser chases energy savings with TF launch
Kaeser has extended its range of TF-series refrigeration dryers with the addition of a 25-m?/min capacity unit, the TF 251, which offers increased energy efficiency, according to the company.
Kaeser has extended its range of TF-series refrigeration dryers with the addition of a 25-m³/min capacity unit, the TF 251, which offers increased energy efficiency, according to the company.
The TF 251 operates with a low-pressure differential of less than 0.19 bar.
This enables the maximum working pressure of the connected compressor to be reduced.
Lower working pressure equates to less energy demand and reduced costs.
For example, a pressure reduction of only 0.5 bar lowers energy consumption for compressor drive power by approximately 3%.
But these are only some of the advantages that high-energy efficiency dryers have to offer.
Some models, for example, use up to 40% less energy than previous TF-series units, according to Kaeser.
Kaeser’s integrated ‘Secotec’ cycling control also provides energy savings.
The heart of the system comprises a thermal mass that allows the dryer’s refrigerant compressor to operate at partial load.
This means that it is activated only when the heat capacity limit of the thermal mass is reached, enabling savings of up to 90% compared with conventional cycle control dryers.
The resulting reduction in energy costs per dryer can amount to several thousand dollars per year, says Kaeser.
Two operating-hours counters, which can be viewed through a window in the enclosure, enable the user to directly track these savings at any time.
Condensate separation systems ensure that the required compressed air quality is maintained at all times, even under high ambient operating temperatures.
The monitoring function of the temperature sensor provides added reliability.
According to the company, other important features such as compact design and user-friendliness add to the many advantages that TF series dryers have to offer.
Both air- and water-cooled models are available.
