HDT
HEATLESS ADSORPTION DRYERS
Flow rate: 19 ÷ 9 060 m3/h
The HDT range is used in situations where a refrigeration dryer dew point is insufficient under ISO 8573.1.
Share
The HDT range is used in situations where a refrigeration dryer dew point is insufficient under ISO 8573.1. This includes electronics, pharmaceuticals, foodstuffs, pneumatic conveying industries, or in installations with low ambient temperatures. With its cold-regenerated adsorption dryer technology, a dew point down to -70°C can be achieved. These dryers consist of two parallel tanks filled with adsorbent material (molecular sieve): while one column dries the air, the other is regenerated with a small part of the already treated air. Units are equipped with an inlet de-oiling filter and an outlet anti-dust filter. The DDC15 electronic controller (industry 4.0 ready), available on the entire range, provides an intuitive interface for monitoring operation and scheduled maintenance. It manages time-based regeneration cycles (or using optional dew point probe).
MAXIMUM WORKING CONDITIONS
- Ambient temperature: + 50°C
- Inlet air pressure: 16 barg (HDT3÷25) / 10.3 barg
- Inlet air temperature: + 50°C
Data refer to the following nominal condition: inlet air pressure 7 barg; inlet air temperature +35 °C
- Desiccant towers
- Shuttle spool valve
- Regeneration drain solenoid valve
- Silencer
- Regeneration nozzle
- DDC15 Electronic Controller
- Inlet oil filter (0.01 micron)
- Outlet dust filter (1 micron)
- Inlet filter condensate drain
- Pressure switches – Fail to switch alarm (optional)
- DewPoint meter (optional)
- Upon request different Power Supply or pneumatic control dryers.
- IP55 pressure switches to enable the “SWITCHING ALARM” function of the DDC15 instrument
- pressure dew point meter, complete with cell and sampling system, interfaced with the DDC15 instrument. Includes instrument calibration certificate.
- Pressure Switch Kit + Dew Point Meter.
- CE certification for pressure tanks up to 16 Bar
- Annual or 3000 hour maintenance kit / Two-year or 6000-hour maintenance kit / 3 year or 9000 hour desiccant material replacement kit
