NOTES
Configuration of unit with spray system can change from standard: please take into consideration adiabatic configuration
§ §
of approval drawing of unit.
The unit is supplied complete with all its parts mounted: should the upper ramps result turned downwards (or demounted)
§ §
it is for the scope of meeting the maximum acceptable dimensions of the unit for transportation.
If required, the customer can rotate the entire ramp since they are connected by joints that enable this rotation:
§ §
ThermoKey can answer on matters of nebulization efficiency of the adiabatic system only when in standard configuration
(with nozzle defined by ThermoKey and with installation defined by ThermoKey).

TC 8. Materials
Most sensitive part concerning the promotion of microbiological growth is the coated heat exchanger. Causal for possible
proliferation is:
For some species the polymer coating can be a possible food source.
§ §
The heat exchanger is wet nearly complete with spray water.
§ §
While passing the heat exchanger, the water is warmed up.
§ §
Dirt from the air intake can be caught in the fins of the heat exchanger and is also a possible food source.
§ §
Due to uncorrected make up of the spray water deposition of lime (scaling) can occur.
§ §
Therefore the following actions on the heat exchanger must be done and documented regularly:
Position Inspection for Frequency Action to be done by indication
1 Microbiological growth Monthly Mechanical cleaning* and disinfection**
2 Dirt from air intake Monthly monthly Mechanical cleaning*
3 Scaling Monthly Mechanical cleaning* and control of the spray water quality
4
Spray nozzles Monthly Mechanical cleaning or exchange
5 Damage Half a year Reparation in accordance with ThermoKey
6
Corrosion Monthly Reparation in accordance with ThermoKey
* Methods for mechanical cleaning:
Soft brush.
§ §
Compressed air, maximum pressure: 2 bar.
§ §
Water, maximum pressure: 2 bar.
§ §
To prevent a deformation of the fins, the air and water jet must be directed vertical those, at a minimum distance of
200 mm.
