Designed primarily to meet the requirements of MIL-STD 888, method
1010 temperature cycling, and MIL-STD 202, method 107 thermal
shock, these chambers test the resistance of electronic components and
assemblies to sudden and severe temperature changes.

In addition to the popularly-sized 2 ft
chambers, Tenney offers the T-Shock Jr., a benchtop thermal
shock chamber with ¼ ft
accommodate pilot runs and the smaller production quantities
of sophisticated discrete components, the T-Shock Jr is an
efficient, cost-effective alternate to large capacity thermal
shock chambers. Also, because the cold-zone is a fullrange Tenney Jr. unit, the T-Shock Jr. doubles as a
high-low temperature test chamber.

Performance evaluation was made with a distributed
product load of 16 pin dip devices. Low temperature
-65ºC; high temperature +150ºC. Sensors embedded in
load samples achieved a 15 minute recovery per
MIL-STD-883C Notice 5, Method 1010.7 and air
temperature recovery was 5 minutes per MIL-STD-202F,
Method 107G. Performance data are based on 24ºC
ambient at sea level. Standard operating voltages 208,
230, or 460V; 3Ø; 60 Hz. On 50 Hz, performance may
be reduced.
TSD model capacities are for total load divided into two
compartments.

One of the most compact thermal shock chambers in the world, Tenney’s
T-Shock Jr. takes up fewer than 10-square feet of bench area but provides
complete thermal shock testing while doubling as a standard test chamber.

Thermal shock testing is achieved by
quickly and repeatedly transferring a
specimen between a hot and cold
station by a means of an automatic
work transfer basket. The transfer
method is more efficient than cooling
and heating a specimen within the same
compartment. Most systems are
available in either a horizontal or
vertical orientation.
Thermal shock chambers are
offered in three configurations:
Two-Zone Operation
Three-Zone Operation
Dual Load Operation

a product basket transport system

In this arrangement, the cold chamber
is stationary and the carriage moves in
and out of the cold chamber. The hot
chamber moves back and forth over
the carriage, which when not covered
by the hot chamber or residing in the
cold chamber dwells in ambient air. The
ambient-exposure can be programmed
out, resulting in two-zone hot-cold
operation. The chamber conditioning
systems operate continuously, allowing
continual production testing and
maximum throughput.

The product is transferred horizontally
between hot and cold chambers in a
two-basket transfer carriage. Three
chambers are used, one hot chamber at
each end and a cold chamber in the
center. This configuration allows
uninterrupted operation of the cold
zone, doubling product load handling
capability for high production applications while increasing operation
efficiency and decreasing operation
costs.

All models feature vapor-tight,
continuously welded stainless steel
interiors. Structural reinforcement is
used at all critical points. Through-wall
ports are continuously welded. A
combination of fiberglass and polyurethane insulation surrounds the chamber to maximize insulating characteristics, thus ensuring minimal thermal
transfer.

All thermal shock chambers, with
the exception of the T-Shock Jr., utilize
an efficient water-cooled cascade
refrigeration system designed to
operate with maximum loads for
continuous periods of time. The
T-Shock Jr. features an air-cooled
cascade system.

Low-mass nichrome, open wire heating
elements are used to reduce thermal
lag and provide rapid response to
instrument demand. The heating
elements are isolated from the
workspace to reduce radiant influence
on the test item.

All wiring complies with NEC. Circuit
breakers are used throughout the
electrical system and are located, along
with other electrical components, in a
readily accessible, integral control panel.

Since the unit’s chamber is continuously welded, the door remains as the
final sealing surface to maintain atmosphere integrity. All doors are
equipped with double gaskets that trap
air for the purpose of insulation. A
unique, energy-efficient system circulates hot gas from the refrigeration
system to provide automatic defrost
for the door gaskets, thus ensuring
pliable gasket conditions and extending
gasket life.

Carriage transport is automatically

In line with our policy of continual product improvement, Tenney
Environmental reserves the right to incorporate and use material to
conform to the latest design of our products in keeping with the
specifications of this equipment. Our standard equipment uses a dewpoint
coil (low surface temperature) to obtain low relative humidities. This
approach can lead to time-limited performance at low relative humidities.
Please discuss specific test and cycling requirements with our sales
department.
