Product Overview
The ThermoVault Max is an extreme, high temperature thermal
barrier designed for use with the HiTemp140 series. This
durable thermal barrier can withstand temperatures up to
+400 °C in dry heat applications and +250 °C in wet applications
when used with the TMAX Wet Seal Kit (optional accessory).
Getting Started
Dry Applications
The HiTemp140-FP, HiTemp140-PT HiTemp140-M12 can be used for dry applications up to +400 °C.
1. Unscrew the lid of the thermal barrier.
3. If using the HiTemp140-M12 data logger,
screw the probe into the bottom end of the
barrier lid.
2. Feed the probe of the data logger through
the bottom end of the lid.
4. Slide the data logger and lid back into
the barrier body and screw the lid back on
tightly.

Wet Applications
For use in wet applications, the TMAX Wet Seal Kit (sold seperatly, optional accessory)
should be used with the HiTemp140-FP, and HiTemp140-PT data logger. When used in wet
applications the maximum operating environment cannot exceed 250 °C (482 °F).
The TMAX Wet Seal Kit Includes:
»PTFE Thread Sealing Tape
»Fitting Body
»Dome Nut
»Compression Ferrules: PTFE (5), Stainless Steel (1)
»O-Ring
1. Unscrew the endcap of the thermal barrier. 2. Stretch the O-Ring over the endcap so it sits
in the groove just beneath the knurled shoulder.
Installing the O-Ring: The O-Ring ensures a tight seal which prevents liquid from entering
the inside of the barrier. O-Ring maintenance is a key factor when properly caring for the
ThermoVault Max. Please refer to the application note “O-Rings 101: Protecting Your Data
Logger,” found on the MadgeTech website, for information on how to prevent O-Ring failure.
1. Wrap the provided PTFE thread sealing tape
around the Fitting Body threads.
2. Screw the Fitting Body into the end of the
stopper assembly (finger-tight).
Securing the Compression Fitting: The compression fitting is used with the HiTemp140-FP
and HiTemp140-PT data loggers to ensure a water tight seal.

7. Insert the data logger and stopper assembly
back into the thermal barrier and screw the
endcap of the thermal barrier until the O-Ring
is no longer visible.
3. Holding the smooth metal end of the stopper,
use a 7/16” wrench or socket to tighten the body
into the stopper.
5. Feed the data logger probe throw the
Compression Fitting until the base of the probe
is tightly against the Dome Nut.
4. Insert the Compression Ferrule into the
Fitting Body and hold it in place loosely with the
Dome Nut.
6. Tighten the Dome Nut to secure the data
logger in place (finger-tight).
Compression Ferrule Note: The stainless steel Ferrule provides the most reliable seal, but becomes
permanent crimped onto the probe. The PTFE Ferrule will become more deformed with multiple uses
and will eventually require replacement. It’s benefit is that it allows easy removal and repositioning of
the probe.

Please consult the measurement range of your data logger for temperatures over 250 °C (482 °F).
The thermal barrier extends the operating temperature of the data logger up to, but not exceeding
the measurement range.

Listed specifications can be used to determine maximum allowable exposure times for the
HiTemp140 with ThermoVault Max. The barrier extends the operating temperature of the logger up
to, but not exceeding, the measurement range. Please consult the measurement range of the probe
for temperatures above 250 °C (482 °F).
Both the data logger and ThermoVault Max must be at ambient temperature, approximately 25
°C (77 °F) before being placed in the extreme temperature environment. Immediately following
exposure to high temperature, the data logger should be removed from the ThermoVault Max, using
appropriate precautions, as it could be VERY hot. Failing to remove the data logger may allow heat
trapped in the ThermoVault Max to continue to heat the data logger to potentially unsafe levels.
The ThermoVault Max may take hours to fully cool down. Even if the exterior of the ThermoVault Max
is cool to the touch, the interior of the barrier and its contents may still be VERY hot.
The ThermoVault Max is primarily intended for use in dry air environments, but with the addition of
the TMAX Wet Seal Kit, the ThermoVault Max may also be used in liquids and steam environments.
If your application involves a ramp up to a temperature above 150 °C (302 °F) and/or any complex
temperature profile that isn’t a constant process, please contact MadgeTech to determine whether
the HiTemp140 with ThermoVault Max is suitable for the application.
To determine if the HiTemp140 with ThermoVault Max is suitable for the application, please provide
MadgeTech with a detailed description of your process, including temperatures, durations, ramp
times and process media such as air, steam, oil or water. If MadgeTech is unable to definitively
calculate the suitability of our product for your application, a test unit outfitted with a high
temperature indicator can be provided.
