TC 8 . General maintenance and control
TC 8.1
Before performing any maintenance work ensure that the power supply of the model has been sectioned: the
electrical parts may be connected to automatic controls. All maintenance work should be performed by qualified
and experienced personnel.
TC 8.2
The EPS system principally consists of: the evaporative modules, composed of a supporting frame in stainless steel,
a treated cellulose panel, a cross connection water distribution, high density polyethylene piping for connection to the
water supply, high density polyethylene piping for connection to the wastewater network, and a discharge pipeing UV
resistant polypropylene.
TC 8.3
Periodically check the fixing points of the module, the water supply and wastewater connections, and the electrical
connections that are found in the required equipment configuration.
TC 8.4
The modules of the EPS system are removable for possible winter storage. Consider, in line with climatic conditions,
storing modules during prolonged periods when the adiabatic system is not in use, in order to increase the operative
lifetime of the panels. During storage, keep modules in a dry place, protected from dust and direct sunlight, possibly
by reusing the original packaging.
TC 8.5
The module frame can be completely disassembled for the programmed replacement of the evaporative panel.
The efficiency and lifecycle of the panel material is determined by the mineral characteristics of the water used, the
air intake, and the amount of use and possible storage.
TC 8.6
To obtain an optimal operation, the flow of air must be as uniform as possible across all areas of the panel. This has an
influence on both the effectiveness of the panel and on the operation of the machine (the vertically mounted panels
make the most of this condition). It is advisable to make periodic checks to prevent or remove obstructions to the
passage of air.
TC 8.7
Provide for the inspection and periodic cleaning of the evaporative panel. The correct passage of air and the wettability
of the panels must always be ensured. Not doing so may compromise the operative efficiency of the adiabatic system,
with a consequent reduction of the performance expected when selecting the product. Perform at least one daily
water-wash cycle and one drying cycle of the panels (see chapter on practical conditions of use). Replace the panels
when there is an obvious deterioration or when cleaning is no longer effective (5% of the front surface of the panel).
The performance of the heat exchanger is guaranteed only with panels supplied by ThermoKey.
TC 8.8
Clean the evaporative panels with a soft bristle brush, and then run a cleaning cycle using fresh water.

EN
TC 8.9
Provide for the periodic inspection and cleaning of the water distribution system. Do not use aggressive detergents,
solvents, acid or alkaline solutions containing chlorine or ammonia, or abrasives in general. If sanitising agents must be
used, check their compatibility with the materials first. The nozzles are removable for programmed cleaning, and can
be washed with substances suitable for removing the deposited limescale. If in any doubt, contact the Manufacturer.
TC 8.10
The frequency of inspection and maintenance operations is dependent on the environmental characteristics and on
the specific characteristics of the feed water and any treatments used, and therefore must be defined on an individual
basis.
TC 8.11
To guarantee the maximum efficacy of the EPS system, check that the operating parameters, namely the measurements
of relative humidity, ambient temperature, and air output temperature from the panel conform to the expected
characteristics of the product selected.
TC 8.12
If proceeding with the replacement of worn panels, contact the Manufacturer for replacement materials.
TC 8.13
Provide for the checking of the chemical and microbiological parameters of the water used in the EPS system
before every period of operation, and programme the frequency of inspections so as to maintain the characteristics
required (see chapter on characteristics of the water).
TC 8.14
For any operation on the product not described in this manual, contact the Manufacturer.
TC 8.15
For the cleaning of the heat exchangers see the technical manual IS.
TC 9. Practical conditions of use
TC 9.1
The water used for the adiabatic system with evaporative EPS panel does not require specific treatments. However,
for a longer lifespan and more efficient operation of the evaporator panel and reduction of maintenance work, it is
suggested to use water with the characteristics indicated in the table.
REFERENCE WATER PARAMETERS FOR EPS SYSTEM
pH (@25°C) 6.5 ... 8.0
Total hardness 3.5 ... 4.0 °d (1°d = 17,85 ppm CaCO3, 1°f = 10mg/l = 10 ppm
CaCO3)
El. Conductivity (@25°C) < 1500 mS/cm
Chlorides < 50.0 mg/l
Sulfates < 90.0 mg/l
Nitrates < 50.0 mg/l
Silicon < 20.0 mg/l
Iron dissolved < 0.1 mg/l
To avoid spontaneous corrosion and/or incrustation, the Langelier saturation index (IL) and the
Ryznar stability index (IR) should be within the following range: IL -1 ... +1 / IR 5.5 ... 6.6
TC 9.2
Water shared by the common water network or water derived from other water resources can be used, possibly to
be treated appropriately with the expectations of material durability and cost of treatment, but measures must be
taken for all chemical and microbiological parameters directly related to health in compliance with the current
legislation and Directive 98/83 / EC. In accordance with what is stated in the use and maintenance manual, the
Thermokey Adiabatic Evaporative System is in compliance with the requirements of VDI 2047-2.
TC 9.3
The feed water should never get down below the minimum level of pH 5 and overcome the maximum level of pH 9,
in order to avoid problems of chemical aggression to the panels. Water hardness should never exceeding 250 ppm
CaCO3. In the event that the system is configured to recirculate the water, purging cycles should be performed in
order to prevent the salinity level exceeding the acceptable limits.
TC 9.4
The installer must ensure that the treatments and chemical substances added, in order to respect the parameters
indicated, are compatible and do not cause any corrosion and damage to the materials used in the module. If necessary,
the water used must be conditioned by the addition of suitable inhibitors of corrosion and incrustation
TC 9.5
Do not routinely add oxidising agents to the feed water as this can create problems for the cellulose sheet of
the panel. If necessary, endeavour to use them only in minimal quantities: max 1 ppm in the case of continued
treatment, or max 5 ppm in the case of a one-time treatment.

TC 17. Operational guidelines
TC 17.1
The EPS system is not suitable for operation at ambient temperatures below 3°C. The system is therefore provided
with solenoid valves for the discharge of the piping and possibly of the recirculation tank when present. If the
ambient temperature falls below the limit specified the operating command is blocked.
TC 17.2
The environmental characteristics of temperature and relative humidity determine the cooling capacity of the
evaporative panels. Preset the detection of these parameters for monitoring as provided for by the design.
TC 17.3
Operation for assisting the motorised fan (or water saving): the main parameter that must determine the start up of the
EPS system, or the opening of the discharge solenoid valve, or the signal to the recirculation pump in systems with a tank,
is the reaching of a programmable temperature or process pressure that the ambient air can no longer control. Shutdown
will occur if the detected value falls below of a range that can be programmed to optimise and reduce uctuations in
operation. A control panel must manage the operation of the EPS system (e.g. the consent to the intake and discharge
valves, the possible regulation of the water ow rate, the washing cycles, the sanitisation cycles, the reading of the sensors,
the ranges of intervention, etc.). If the model is equipped with regulated motorised fans (electronic or inverter) from a
dedicated control panel, the fan motor control logic will pilot the control panel of the EPS system.
TC 17.4
Combined operation for the motorised fans (or energy saving): the EPS system can be put into operation to reduce
the temperature of the air intake in combination with the operation of the motorised fan for choking the airflow. This
function can be used on models equipped with regulated motorised fans. The main parameter that must determine
the start up of the EPS system, or the opening of the discharge solenoid valve, or the signal to the recirculation pump
in systems with a tank, is the reaching of a programmable speed of the motorised fan. Shutdown will occur if the
detected value falls below a range that can be programmed to optimise and reduce fluctuations in operation. A control
panel must manage the operation of the EPS system (e.g. the consent to the intake and discharge valves, the possible
regulation of the water flow rate, the washing cycles, the sanitisation cycles, the reading of the sensors, the ranges of
intervention, etc.) that is piloted by the control panel dedicated to the motorised fan.
TC 17.5
For the setting of the operating parameters, refer to the manual of the electric control panel of the EPS system.
TC 17.6
For the water consumption of the adiabatic system, the following parameters were defined:
MIN = theoretical water consumption referring to technical data
MID = practical working water flow (about 4 l/min of water per panel)
MAX = cleaning water flow (discretionary, about 6 l/min of water per panel)
TC 18. Disposal and recycling
TC 18.1
Disposal must be carried out by qualified and qualified personnel in accordance with the environment as prescribed
by current legislation.
