Original F4 Temperature Controller
Up to 256 steps can be programmed into as many as 40 nameable 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 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 3in Access Ports
Model 115A chambers include two 3in ports (2.83in 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.

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.
