TestEquity Model 3007C FastRate™ Temperature Chamber provides fast temperature transition rates in a compact, self-contained package. Dual 3.5 HP scroll compressors, boost heaters, and two heavy-duty blower motors give you the extra capacity you need for ramp rates in excess of 10°C/minute without liquid nitrogen (LN2). If you need even more cooling capacity, optional LN2 boost cooling is available.

More Effective Reliability Screening
Many temperature cycling specs require ramp rates of 5°C/minute to 10°C/minute in order to effectively screen for various failure mechanisms. Model 3007C FastRate™ Temperature Chamber is capable of meeting these requirements.

Faster Test Time
Model 3007C FastRate™ Temperature Chamber is ideal for applications requiring fast throughput. For example, you might need to cycle an item from +85°C to -40°C. A 1007C would take about 1 hour to cycle hot-to-cold and cold-to-hot, while the 3007C can do it in 17 minutes. If you need to repeat this cycle 10 times, the 3007C will save you 7 hours of test time!

High/Low Limit ControllerHigh/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 sampl

Heavy Duty Blowers
The system includes two forward curved stainless-steel, welded-construction blower wheels in a counter rotating pattern to provide high velocity airflow throughout the workspace, driven by two heavy-duty motors.

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

Event Relays Standard
Three uncommitted solid-state relays are provided to switch the power to remote AC devices via the F4 Temperature Controller

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
The chamber floor is sloped and has a drain to permit removal of condensate that can occur when cycling from low to high temperatures.

Rugged casters permit easy movement.

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

World's Best Environmental Chamber WarrantyWorld'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.


LN2 (Liquid Nitrogen) Boost Capability (optional)
Provides extra cooling capacity for higher ramp rates and increased load capacity. For example, cooling with compressors only from +85°C to -40°C in an empty chamber is at a maximum rate of 12°C/minute. With optional LN2 Boost, the cooling rate for that condition increases to 20°C/minute. Or, with a 25 pound load, the rate increases from 8°C/minute with compressors only to 12°C/minute with LN2 Boost.

The system uses a specially-designed cryogenic solenoid valve to regulate the flow of LN2 in the chamber. A redundant cryogenic solenoid valve provides low-temperature protection in the event of a control valve failure, a controller failure, or operator error. The valves are located in a double-insulated sealed compartment to minimize thermal losses and prevent moisture condensation.

No-Sweat Cabinet
We use a combination of structural urethane 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 fused. 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.
