SFD Sub-Freezing Dryers

Air flow rate from 360 m³/h to 1600 m³/h

The revolutionary SFD dryer is currently the only -20°C PDP refrigerant dryer available on the air treatment portfolio. It combines the subfreezing pressure dew point of a traditional regenerative adsorption dryer with the low functioning and energetic cost of a refrigerant dryer, offering an extremely reduced total cost of ownership.

Features

Standard features:

Removable panels for easy inspection and maintenance
Electric protection IP42
Electronically actuated smart solenoid drain valves (no-loss drain)
with electronic feedback to the controller
Programmable controller
Victaulic© fittings for and easy maintenance
R452A refrigerant gas

Optional features:

Kit for low ambient temperature (SFD 360-420)
Kit for low inlet temperature (SFD 360-420)
External modification/IP54 protection (all models)A single condensate drain is used for the entire package.

High air quality, Class 3 ISO: 8573-1 with a -20° PDP

Delivered without any interruption throughout the whole recommended working range.

Excellent for systems where piping or pneumatic equipment are exposed to subfreezing temperatures.

Patented heat exchanger

With a double cooling chamber and a pre-cooler that provides a subfreezing pressure dew point, reducing functioning and energetic costs.

No purge air needed

For the regeneration, with remarkable improves in the energetic efficiency.

No expensive consumable

Such as drums or desiccant media that need to be changed, reducing the cost of maintenance.

Innovative controller with embedded connectivity module

Which ensures high air quality and, thanks to his intuitive and high definition display, allows to monitor the performance. Moreover, it is equipped with a remote connection with Internet browsing and a SD card that stores constantly the I/O of the dryer.

Easy to install

Footprint reduced of the 40% compared to a corresponding adsorbing dryer and complete match with all compressors, without any need for expensive change outs or previous particle filtration.

Smart exhaust valve

Which works differently according to the demand, to guarantee a complete clearance of water in every cycle.

Three options that make the SFD dryer suitable for all needs:

• Opt low inlet air temperature: extends working range up to a minimum compressed air temperature of 5°C (SFD 360-420)

• Opt low ambient temperature: extends working range up to a minimum ambient temperature of 10°C (SFD 360-420)

• Opt outdoor installation: allows the dryer to be installed outdoor , sites protected by a roof, thanks to the IP54 electrical protection level (all models)
