Thermal Shock Chambers
TSA Series

CAT.NO.E14138

Now more reliable than ever,
the TSA series provides network connectivity
The TSA series is ESPEC's best-selling damper-type thermal shock chamber.
The TSA series is equipped with the kind of useful features that are typical of ESPEC.
With new instrumentation featuring significantly increased processing speed and network
connectivity, it is now possible to monitor and manage the status of test chambers in remotelocations while sitting at your desk.
This functionality will result in more reliable tests and reduce the workload of the test conductor.
Experience the improved ease-of-use of the TSA series for yourself.

Automatic setting of
pre-cooling and pre-heatingin energy saving, Eco
operation mode [patent 5204808]
The new series incorporates an algorithm
that calculates the minimum operation
time for pre-cooling and pre-heating byconstantly measuring the amount of heatrequired for these processes in eco
operation mode. This feature can further
reduce power consumption and remove
the inaccuracies and hassles caused byadjustments based on preliminar y
experiments. Tests operation achieves both
energy savings and reproducibility/
reliability.

Parallel refrigerator control
system for energy-saving
control [patent 5487167]
To optimize further the power consumption,
the chamber features a parallel control
system that connects two small refrigerators
in parallel to the secondary side of therefrigeration circuit. The chamber canoperate at the optimal refrigeration capacity
based on the controlled temperature, byswitching operation bet ween t wo
refrigerators simultaneously or a single
refrigerator. At stable low-temperature
exposures, power consumption is also
reduced by limiting refrigeration capacitywith an electronic expansion valve.

Characteristics

TSA-73EH-W
Test start

Until now testing was interrupted for
defrosting when necessary, but ESPEC
has developed a unique structure that stops
frost formation under low temperaturesby preventing the penetration of outsideair (defrost-free operation [patent 3514735]).
Defrosting during cycle tests is thenunnecessary, thus reducing defrosting time
and the power consumed for thisoperation.

TSA−203ES−W measurement example

Specimen temperature(℃)

Dampers with integrated rectifying
function minimize variation in exposure
conditions due to specimen position within
the test area. This reduces the overall test
time and shortens temperature recovery
time, especially during low-temperature
exposure. The uniformity in test conditions
brought by this innovation also contributes
to improved test reproducibility andreliability.

Backtrace function

Backtrace setting● Online Diagnostics Service

Backtrace data are created when thechamber triggers an alarm. All items
required for chamber control including
set temperature, measured temperature,etc. are recorded for the period before
and after the alarm was triggered.
When the chamber stops because oftrouble, the operation state just before
the chamber stops is automaticallyrecorded and saved. Saved data can besent to ESPEC, by using our Online
Diag nost ics Se r v ice, a nd we w i l lperform troubleshooting.

(http://www.espec.co.jp/english/support/onlinediagnosticsservice.html)

Online Diagnostics Service
Online Diagnostics service is available
using the backtrace data recorded by thechamber. Send the backtrace data to
ESPEC via email; we will analyse thecause of the trouble and repor t thediagnosis back to you.
T h i s s e r v ic e e n s u r e s a c c u r a t elyperformed diagnosis s that, in caserepair work is required, appropriate
t roubleshooting will be prescribed
ensuring reduced testing downtime.

International Standards
The TSA series supports the following
safety standards: Safety of machinery(ISO 12100,) Low voltages (IEC 60204,)and EMC (IEC 61000-6 -2 and IEC
61000-6-4).
It is also RoHS- and Pressure Equipment
Directive-compliant.
(Only models with power supply voltage
of 400 V/415 V are PED-compliant.)

Defrost-free operation

For two-zone tests, enables continuous tests
without requiring defrosting for up to 500
hours max.
ESPEC has developed a unique structure(patent: 3514735) that prevents the penetrationof outside air and uses recirculated air during
testing to stop frosting on the low-temperatureside.
This enables continuous tests up to 500 hours,
so around 20 defrost cycles during this period
can be eliminated.
This option can reduce both the test time in
the amount of the defrosting time (approx.
60 minutes each time) and the power
consumption required for defrosting(13.6 kWh each time).
