Energy-saving refrigerated dryers with Demand Manager control


Models: TF 171E to TI 901E
Capacities: 600 to 3000 scfm at 100 psig

Demand Manager models efficiently handle systems that are started and shut down routinely and have a constant air demand.

Important features and advantages:

  • Low pressure drop, non-fouling heat exchanger
  • Low pressure drop filtered separator with microprocessor controlled filter monitor removes liquids and particulates down to 3 microns
  • Zero-loss electronic ECO-DRAIN for reliable condensate removal
  • Hot gas bypass control
  • State-of-the-art control system with timed auto-start and stop
  • Optional cold coalescing oil removal filter eliminates oil aerosols to 0.008 ppm

Energy-saving Controls

Real energy-savings are the result of the right dryer and optimized dryer control system. A dryer should only consume electrical power when actually drying air.

For example, a Dual Control dryer is ideally suited for applications with varying demand. Its direct expansion, on/off load refrigeration system ensures a consistent dew point. With a 60% air demand, the controller tells the digital scroll refrigeration compressor to operate loaded at 60% of the time. With the compressor off during the remaining time, 40% of dryer power consumption is saved.

In another example, a Demand Manager dryer with its non-cycling, direct expansion refrigerant system and rapid response by-pass will ensure tight temperature control and uniform performance in applications having consistent demand.

The auto start/stop timer, standard on both models, also contributes to energy savings by allowing the dryer to automatically start and shut off at pre-determined times.

Plus, every kilowatt saved reduces emissions. A dryer running in an air system may handle perhaps 50 to 70% of the full load - conditions that particularly favor a Dual Control dryer. Annual savings can run into thousands of dollars.
