Safekeeping of the operating instructions
The operating instructions for the temperature control unit belong in the
hands of the personnel responsible for start-up and operation. Please
ensure that the operating instructions are read. By doing so, you will
avoid unnecessary expense and problems during start-up as well as pro-
duction downtime.
Inspection of Consumers
Before installing the connecting lines between consumer and tempera-
ture control unit, the consumer must be subjected to the following inspec-
tions:
•
Verify that channels are unobstructed
•
Remove residual fluid and fouling with compressed air (foreign
objects such as shavings etc. can damage the pump)
•
Rust and scale deposits and oil residue must be removed be-
cause they greatly interfere with the heat exchange between con-
sumer and heat transfer medium and increase the pressure drop
in the consumer. Descaling can be carried out using the Re-
gloplas REG descaling unit (see the "Regloplas Temperature
Control Technology" brochure, REG data sheet)
•
Oil deposits can be removed with the SR80 system cleaner (see
the "Regloplas Temperature Control Technology" brochure,
SR80 data sheet)
When converting the consumer from operation with water to thermal oil,
all residual water in the consumer and in the connecting lines must be ful-
ly removed (danger of accident due to vapour pressure when heating) -
see chapter on "Converting the consumer from water to thermal oil"
Water Quality
The water used must meet the following requirements to avoid damage
to the cooler of the temperature control unit:
Criterion
Requirement
Appearance
clear/without sediment
Cloud
< 0.5 NTU (very light cloud)
Total hardness
< 10 °dH
pH-value
6.5-8.5
Conductivity
max. 500 µS/cm
Carbonate hardness
< 5 °dH
Addition of RK93 corrosion inhibitor is urgently recommended (see the
"Regloplas Temperature Control Technology" brochure, RK93 data
sheet).
Thermal Oil
Regloplas recommends the thermal oils Regloplas RO300 or Thermi-
nol 66. The film temperature of the thermal oil must be 40 °C above the
outlet temperature of the temperature control unit.
