Additional Product Information

The Features You Want - Included at No Extra Charge...

Programmable Temperature Controller
Up to 256 steps can be programmed into as many as 40 namable profiles. The context sensitive information key and guided steps make profile programming fast and easy. A four-line backlit LCD displays programming, setup, operating and help information. A large LED readout indicates the actual chamber temperature with 0.1° resolution. Internal logic provides refrigeration compressor control for responsive and reliable performance. Includes two alarms and seven event outputs to control remote devices. RS-232C communications is also included. GPIB, Ethernet and analog retransmit are available as options.

High/Low Temperature Limit Controller and Alarm
Provides independent protection against excess temperatures. Both high and low limits can be set. The upper LED readout indicates the actual chamber temperature while the lower readout indicates the status The limit controller will shut down the chamber and trigger the audible alarm in the event of an out of limit condition. A set of uncommitted contacts are available to provide a safety power interlock for your test sample.

Viewing Window
Our unique design virtually eliminates exterior window sweating during normal temperature cycling conditions.

Two 4" Access Ports
Lets you attach wires and sensors to your test sample through both the left and right side of the chamber.

Adjustable Shelf
A heavy-duty stainless steel wire shelf ensures proper airflow around your test sample for uniform temperature distribution.

Chamber Condensate Drain
Now included in all new 1007C chambers. The chamber floor is sloped and has a drain to permit removal of condensate that can occur when cycling from low to high temperatures.

Casters
Rugged 3" casters permit easy movement.

Built-In Refrigeration Gauges
Provides system status for easy preventive maintenance and service.

World's Best Environmental Chamber Warranty
Only TestEquity offers a 3-year warranty on parts and 1-year warranty on labor. Our nationwide service network is qualified to do the job right. And we always have replacement parts in stock for immediate shipment. Labor warranty applies to the United States and Canada only. See the complete warranty statement here.

TECHNICAL FEATURES

No-Sweat Cabinet
We use a combination of structural foam and fiberglass blanket insulation for a higher combined R-factor than just fiberglass alone. The door sealing surface is kept warm by circulating excess heat from the refrigeration system. The result is a cabinet that does not sweat due to condensation during low temperature operation.

The window is constructed of 6 panes of tempered glass separated by low-conductivity spacers to keep thermal losses to a minimum. Our unique design virtually eliminates exterior window sweating during normal temperature cycling conditions.

The stainless-steel interior liner is heliarc welded, while the refrigeration compartment behind the liner is double-insulated and carefully sealed. These design features reduce thermal losses and prevent moisture migration, ensuring years of optimum performance while keeping the cabinet rust-free.

Reliability & Safety That's Designed In
Non-CFC refrigerants are used in a cascade (two compressors) configuration. Expansion valves provide optimum performance throughout the operating range. Pressure regulators keep the operating pressures within safe limits regardless of load conditions. Liquid injection ensures cool compressor operation during high-temperature pull down for long life. Sequential starting of each compressor reduces the current demand on start-up. Each compressor is protected by high/low pressure switches. Care has been taken to use a minimum number of fittings, joints and welds to reduce the possibility of refrigerant leaks.

All electrical control components are UL approved. Each branch circuit is individually protected with class-CC fuses. A main power disconnect switch is provided on the front panel. The nichrome air-heater has a low watt-density and even heat distribution for reliable performance and fast response. A fusible link provides fail-safe protection against thermal runaways, in addition to the microprocessor-based high/low limit controller.

The side and rear panels are removable to permit complete access to the refrigeration system for ease of service and preventive maintenance. Shown above with the optional circular chart recorder, which mounts conveniently in the front.

Should I buy a TestEquity 1007S Single-Stage or 1007C Cascade Chamber?

TestEquity Single-stage refrigeration systems are capable of achieving workspace temperatures down to -35°C. This is fine for many commercial and industrial tests that require low temperatures of typically 0°C, -10°C or -25°C. A single-stage system uses one compressor to directly cool the workspace. Single-stage systems offer these benefits over similarly-sized cascade systems:

• Faster cooling rates.
• Higher live-load capacity.
• Quieter operation, more energy efficient (one compressor instead of two).
• Higher anticipated reliability and lower cost of maintenance over the life of the chamber (the 1007S has 35 less parts and 26 less refrigeration connections than the 1007C).

TestEquity Cascade refrigeration systems are capable of achieving workspace temperatures down to -73°C. This is required for many ruggedized industrial, automotive and military tests that require low temperatures of typically -40°C, -55°C or -65°C. A cascade system uses two interdependent compressors. One compressor (low-stage) directly cools the workspace. The other compressor (high-stage) cools a heat-exchanger (cascade condenser) to remove heat from the low-stage. If you need to go below -35°C, choose the TestEquity 1007C.
