Cooling maintenance

­Check if flux is cold after doors. ­Use thermal camera to check doors temperature.

­→ Out air flux is not cold.

• Use thermal camera to ensure and compare with other doors.
• Inspect water arrival and departure pressure if possible.
• Check water quality and PH.
• Determine cooled door heat exchanger material and inspect if galvanic corrosion is not occurring.
• If blocked, dismount door and purge it. Have a special look on solid particles removed: color and aspect are important indicators to identify problem and prevent future fill.

­→ Condensation occur on heat exchanger surface

• Check water temperature and air temperature/humidity, report them in humid air chart and check, dew point is probably reached.

­→ Humidifier is continuously running, or often running (causing electricity, water and maintenance costs)

• Check room humidity with a different probe than the one dedicated.
• Check room humidity regulation.
• Check room air position on humid air chart, and check it doesn’t reach condensation point.
• Check room sealing.

­→ Humidifier is always/often asking for maintenance

• See Humidifier is continuously running, or often running.
• Check inlet water quality.
• Have the equipment checked by a professional.

­→ Condensation occur on heat exchanger surface

• Check water temperature and air temperature/humidity, report them in humid air chart and check, dew point is probably reached.

­→ Compressor is used even with cold water supply

• Check water valves are opened.
• Check if probes values are coherent.
• Check regulation
• If air temperature regulation is too low, unit may use compressor to respond to this high cooling demand.
• If humidity in room is too high, unit will condensate only and not lower temperature (i.e. high load).
• Check internal pipes are not blocked by a fill.
