Instruction book
• As long as the dew point is below the set point (-54 °C for HTM and -45 °C for HTM2022), the drying
tower will remain drying, until the PDP temperature exceeds the set point. On that moment the
regenerated tower will start drying the compressed air and the other tower will be regenerated.
• As long as the dew point is below the set point, regeneration of the non-drying tower is stopped after
a preset time interval has elapsed. As a result, reduction of purge air is achieved.
• CO sensor
The CO sensor is connected to the ES-MED controller and will trigger an alarm when the level of CO
exceeds 50 ppm.
• CO sensor
2
The CO sensor is connected to the ES-MED controller and will trigger an alarm when the level of CO
2
exceeds 500 ppm.
• QDT oil indicator
An oil indicator is available as an option to control the purity of the air. The oil indicator is a calibrated
measuring instrument, used to detect aerosol-mist levels of oil entrainment that may be present in
compressed air systems. Sensitivity of the indicator is limited only by the total number of hours it is allowed
to remain on the air supply system. The indicator is sensitive enough to measure a concentration of oil
entrainment as low as 0.01 ppm. This sensor will indicate when the activated carbon is saturated and needs
to be replaced. The oil indicator has a maximum pressure of 8.75 bar (127 psi).
• QDT filter with CO catalyst (QDT+)
The basic version (QDT filter) only contains activated carbon. A catalyst that converts CO into CO
available as option (QDT+ filter). This option is strongly recommended in polluted areas and makes sure
that the air quality will always comply with the Pharmacopoeia.
• AirContact notification and visualisation
With these options it is possible to monitor the dMED remotely.
