Temperature Cycling Chambers
Global-N Series
Faster test chambers ...
The Global-N series chambers from ESPEC provide the
temperature cycling and humidity performance you need to
validate quality and reliability for increasingly sophisticated
electronics and other products.
The 800-liter (28 cu. ft.) model ts in a space
1.3m by 2.2m (51 by 85 inches), except -15CW models.

The 380-liter (12 cu. ft.) model’s width is just 0.9 meters
(35 inches), tting thru a standard doorway.
Global Features
World-standard performance and features on a minimal footprint
The Global-N chambers have temperature change rates
from 5 to 20°C per minute. In addtion, controlled humidity
from 10 to 95% is an available feature. There are two sizes,
with interior volumes of 380 and 800 liters (12 and 28 cubic
feet). They are compact, requiring the least amount of oor
space for this level of performance.
These chambers feature the classic ESPEC look of stainless steel, with a new, modern style. The control console is
now on the door, making the footprint of the unit even more
compact. A simple, but secure, door latch is easier than ever
to use.
International applications
Global-N chambers meet Mil-Std, JEDEC, IEC, and other
international test performance standards. The units can be
installed around the world for consistent testing at different
facilities, supported by your local ESPEC service group.
Designed for serviceability and safety
For safety and compliance, Global-N series are UL 508A
certied or CE-marked.
Refrigeration service panels are hinged for fast access.
Analog refrigeration gauges help you monitor system performance and pinpoint service needs.
All models feature three levels of overheat protection, plus
two levels of overcool protection. The system controller provides alarm messages with specic troubleshooting help to
quickly resume testing.

Temperature cycling up to 20 degrees
per minute
Global-N’s twenty different models allows you to
choose the size and performance best suited for
your test applications. Temperature cycling rates
from 5 to 20°C/min. are possible. Two different
ultimate low temperatures are available: -40°C or
-70°C.
Models EGNL & EGNX also control humidity, for
expanded testing options beyond temperature
cycling.
Global-N chambers are capable of meeting the
performance requirements of JEDEC, IEC, MilStd, and other international environmental test
performance standards.
Get a performance evaluation to help
select your model
For better assurance of performance for your
temperature cycling application, ESPEC can provide a guaranteed performance calculation based
on your submitted requirements.
Please use these questions (at right) as a guide
to dene your test plan. You can then give this
information to your local sales representative,
or submit at www.espec.com, for review by an
ESPEC engineer. A recommended model with
appropriate refrigeration size will be returned.
SYSTEM & PERFORMANCE OPTIONS
Low and Ultra-low Humidity - Extends •
the humidity control range for EGNL &
EGNX models.
Attached Air-cooled Condenser - For •
applications where water-cooling isn’t
practical. The condenser is on top
of the chamber, adding 350mm (14
inches). Suitable for installation in
sites that are not air conditioned.
Product Temperature Control - See •
next page for details.

Different Global-N models can heat and cool at different rates. Shown
above are change rates for EGNZ12 models, following IEC 60068 3-5
standard, with the sensor in the supply air.
Questions for performance evaluation request:
1. Chamber type
Desired size: 12 or 28 cu. ft.?
Local power: 50Hz or 60Hz?
Humidity control: Yes or No?
Sample description and type of material(s)
Total mass per test, including any racks or cabling
Heat output of samples, in watts, if powered during test
3. Your Test Plan
Test method, if a published standard (e.g. JEDEC JESD22-A104C)
Start temperature for cycling
End temperature for cycling
Ramp rate or time allowed between start and end temperatures
Datalogging Choices - Via traditional •
chart recorders, paperless recorders,
Ethernet, or computer interface.
ECA Modication - Allows condition-•
ing of remotely-located equipment that
cannot be placed inside the chamber.
Dry Air Purge - Keeps moisture in the •
chamber extremely low by purging
with -40° dewpoint air. Compressed
air supply required.
Liquid Nitrogen Injection - Boosts •
cooling rate.

Touch-screen controller enhances performance
Imagine walking up to your test chamber and immediately being able to get your test running. The
exclusive SCP-220 programmer makes it a breeze to
set up, run, and monitor your chamber, even for the
infrequent user.
For temperature cycling, the controller allows you to
select step-ramping for the fastest possible transistion, or controlled-ramping to achieve a desired ramp
rate. Guaranteed soak settings allow you to control
when timed soak periods begin.
Remote operation via Ethernet
ESPEC offers the Web Controller, an embedded
server/software solution that allows monitoring and
programming your chamber via any PC on your
network.
No local software to install, just a web browser and
access to the LAN is required. Because there are
only seven screens, all operational functions are
easy to nd and use. See our separate brochure or
website for more detail.
Remote control and datalogging is also possible via
RS-232 or IEEE-488 options.
The Web Controller is compatible with all USA-built ESPEC models with
touch-screen programmer/controllers, except thermal shock.
Product temperature control generates faster ramp-rates for test samples,
as well as signicant time savings for soak periods.
Ethernet
Optional product temperature control
Monitors product temperature•
Enables faster product change rates•
Shortens testing time •
During cycling tests, product temperature can lag
behind air temperatures by 20 degrees or more. Our
optional product temperature control feature lets
you drive faster change rates by directly monitoring
product temperature and overshooting normal airtemperature setpoints until the product approaches
the desired temperature. By achieving product
temperature faster, soak periods can begin earlier,
saving signicant time.
As shown in the example at left, setting the chamber for a 20°C air temperature boost (air at -60°C)
achieved the -40°C product temperature in just 16
minutes, compared for nearly 50 minutes with the
chamber air set at -40°C.
