Frequently Asked Questions
Can I Modify the Clamshell Process Chambers?
YES.
• The clamshell process chambers (sold separately) are simple and easy to modify.
• The plastic can be cut to customize the box to fit individual process requirements.
• The boxes are disposable. If the box becomes soiled or damaged, replacements are readily available from EFD.
Can I Make My Own Process Chamber?
YES.
For those who wish to make their own process chamber, follow the guidelines below:
• The chamber should cover the entire material path (syringe, valve, fittings, etc, leaving only the needle or exit
point exposed).
• The chamber should have a minimum of “dead air” space. The less space inside the chamber, the easier it is to
maintain temperatures within.
• The chamber should allow the heated / chilled air to circulate freely around the process hardware within.
• The chamber must have a vent that allows air to exit the chamber. Plan ahead to determine where the heated /
chilled air can freely enter, circulate, and then exit the chamber.
• The chamber should either be made of transparent materials, or be provided with a window to allow monitoring
of material levels.
• In order to maintain temperatures well above or below ambient conditions, the chamber should be made
from or contain an insulated material or have double-walled construction. This will help to maintain desired
temperatures.

Troubleshooting
If you encounter a problem that you cannot readily solve, call Nordson EFD.
Problem Possible cause and correction
No power Be sure that there is power available at the wall receptacle.
Unplug the unit. Make sure AC/DC power supply’s main plug adapter is firmly seated and
locked on the supply body.
Make sure that the power lead is firmly inserted and seated at the rear of the unit.
If the unit still does not have power, call EFD for assistance.
Unit will not
maintain pre-set
temperature
1. Make sure the thermocouple is solidly plugged into the rear of the unit and that the lead
is affixed to the process hardware.
2. Check the incoming air pressure and flow. For maximum efficiency, the unit must be
supplied with 6.9 bar (100psi) of clean, dry air.
3. If the pressure is fluctuating or dropping, the unit efficiency will be reduced. Insufficient
air flow will cause degradation to the minimum and maximum temperatures the unit can
provide.
4. Check the air pressure to ensure that it is not varying. If needed, use the filter / regulator
(EFD part #7016547).
5. A slow drop or rise from the desired temperature (usually over the course of several
hours) can be caused by moisture inside the air supply that is causing freezing inside the
unit. This will reduce the air flow and degrade the minimum and maximum temperatures
the unit can provide.
To properly diagnose whether this is occurring, shut off the unit for several minutes to allow
the potential blockage to thaw. Turn the unit back on. If the temperature resumes the required
setpoint, it is a sure sign that moisture is present.
If your process is not dependent on the unit running continuously, shut down the unit in
between runs to prevent moisture buildup in the unit.
The preferred method is to install line dryers: refrigerant type, in-line desiccant, or membrane
dryers. The desiccant and membrane type dryers have been shown to produce substantial
dew point reductions, and are the preferred method to reduce moisture in the unit. These are
available from EFD.
Condensation
forms on the
tubing
Condensation may form on the process supply tubing if temperature setpoints are well below
ambient room temperature and relative humidity is high.
Tube insulation supplied with the unit will prevent condensation from forming and will also
increase overall efficiency.
