Care and Maintenance
Thermal Barriers and Heat Sinks
Cooling
Please observe the safety information on page 5 and the information on cooling down the
protective parts on page 14.
Examination
Always take the heat sinks out of the thermal barrier. Shake the heat sinks to find out
whether the cooling agent has changed form solid to liquid state. If the cooling agent is still
in a solid state, the heat sinks need to cool down for 8 hours at a temperature lower than
+10 °C. If the cooling agent has remained solid, it is sufficient to cool down the heat sinks
for 8 hours at a temperature lower than +20 °C.
Make sure that mechanically damaged heat sinks don’t leak.
Contact BYK-Gardner if the heat sink phase change material leaks. It is a non-toxic wax-
like substance that dries hard powdery white and has a slight acidic smell. Wait until it is
dry before scraping of any material that has leaked onto the surface of the barrier. Please
observe the safety information on page 5.
Examine the cooled thermal barrier and heat sinks for damage before storing in a dry
environment to avoid the ceramic insulation absorbing water.
Check the thermal barrier’s seals and closing mechanism, rectify any damage before
further use.
temp-gard Data Loggers
Store in a dust free environment. Remove batteries when storing for more than two to
three weeks.
Return to BYK-Gardner annually for calibration.
Thermocouple Probes
General
Lifting or removing the probes by the cables will damage the cables and connectors.
Examine cables, and replace any probes found to have damaged insulation.
Mineral Insulated Thermocouple Probes
The thermal cycling the probes experience causes the MI cable to age, and eventually to
become brittle. Handle them with care ensuring the minimum bend radius is greater than
25 mm.
