    Our improved Model 115A Temperature Chamber offers these benefits over our popular Model 115:

    • Bidirectional Control Architecture - reduced energy consumption and better temperature control.
    • Improved Airflow - The conditioning plenum is improved to accommodate a larger fan blade and a more ideal airflow pattern. This results in substantially improved temperature uniformity under real-world loading conditions.
    • Choice of Manual or Programmed On/Off Mode - Allows the chamber to be turned off completely at the end of a stored profile or via computer interface
    • Condensate Drain - The conditioning plenum has a drain to permit removal of condensate from the evaporator that can occur when cycling between low to high temperatures.
    • Field installable GN2 and Dry Air Purge Options - If you change your mind after purchase, you can now install these options easily in the field.

    TestEquity Model 115A Temperature Chamber provides full-range temperature testing in a compact floor standing or benchtop package. Its rugged design includes a variety of standard features, making it an exceptional value.

    Limit ControllerHigh/Low Temperature Limit Controller and Alarm
    Provides independent protection against excess temperatures. Both high and low limits can be set. The limit controller will shut down the chamber and trigger the audible alarm in the event of an out of limit condition.

    Viewing Window and Interior Light
    6-Pane window minimizes thermal losses. Oven-rated interior light fixture protrudes minimally into the workspace.

    Two 3" Access Ports
    Model 115A chambers include two 3" ports (2.83" inside diameter). Lets you attach wires and sensors to your test sample through both the left and right side of the chamber.

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

    Casters
    The 115A-F floor-standing version includes casters to permit easy movement, making the chamber truly portable.

    Reversible Chamber Door
    You won't need to rearrange you whole bench or workflow to accommodate the Model 115A. The chamber door is reversible, allowing the door to open from the left or right side. This is also useful when placing two chambers side-by-side.

    120 Volt Input
    The chamber draws 15 Amps maximum at 120 Volts. You can plug it into any standard 20 Amp wall receptacle. An export version is available with 230 Volts, 50 Hz input.

    TECHNICAL FEATURES

    Reliability and Safety That's Designed In
    Non-CFC refrigerants are used in a cascade (two compressors) configuration. Pressure controls keep the operating pressures within safe limits regardless of load conditions. Liquid injection ensures cool compressor operation during high-temperature cool down for long life. Sequential starting of each compressor reduces the current demand on start-up. 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. 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.

    We use a combination of structural foam and fiberglass blanket insulation for a higher combined R-factor than just fiberglass alone. The result is a cabinet that does not sweat due to condensation during low temperature operation. The side and rear panels are removable to permit complete access to the refrigeration system for ease of service and preventive maintenance.
