Key Features: 1.2 Cubic Feet Work Capacity Maximum Temperature Range from -90°F to +350°F (-67.8°C to +177°C) Air-cooled, mechanical refrigeration system with hermetically sealed compressors Immediate operation with suitable power connection High volume air circulation fan Stainless steel access port

Cabinet:

• The entire chamber is built of high quality steel. No wood, fiberboard, plastic or similar materials are used in the construction.
• The interior is constructed of 304 Series, high-nickel content stainless steel with 2B finish. The liner is heliarc welded for hermetic sealing to prevent moisture migration to insulation space.
• The exterior shell is constructed of die-formed, 16" gauge galveneal.
• Gaskets are extruded, designed to be used with seamless corners. Two separate gaskets are installed to insure minimum heat loss from the chamber -- a silicone inner gasket and a vinyl outer gasket.
• The circulator motor is located outside the chamber. It has a solid stainless steel shaft; no extensions are used. Ball bearings are lubricated for life and located out of the conditioned area.
• A hinged instrument panel makes service and calibration easier.

  Electrical System:

• The chamber has a solid-state, photo-isolated, zero-voltage switching, heat-power relay.
• Chamber has a fusible link heater cut off at +460°F (+288°C).
• All motor electrical components, switches, and fuses are located in a self-contained panel.
• All components are fused.
• Chamber wiring is contained in "panel channel" and is accessible with completely unlacing or unthreading any wires.
• All wires are identified.
• Identification provided on pilot lights and switches for all major circuits.
• Wiring meets NEC and NEMA standards.

  Refrigeration System:

• Refrigeration system has all silphosed or silver soldered joints - no soft solder is used.
• The system is air cooled and capable of starting under various ambient conditions.
• The condensers are manufactured to meet our exacting standards.
• Cooling coils are heavy-duty copper tubing with specially designed aluminum fins.
• The system is sealed and balanced to achieve the ultimate in performance and reliability.

  Performance*: Temperature Pull Down from a Stabilized Control Conditioned of +75°F:

• to -40°F: 15 Min.
• to -65°F: 25 Min.
• to -85°F: 30 Min.
• to -100°F: 35 Min. Temperature Heat Up from +75°F Ambient:
• to +240°F: 20 Min.
• to +350°F: 45 Min.
• (-100°F to +75°F in 15 minutes) Capacity for Holding Live Loads at Temperatures Below +100°F only (dissipation in watts):
• at 0°F: 350 Watts
• at -40°F: 250 Watts
• at -65°F: 200 Watts Control: Air temperature control as measured at the controller thermocouple +/- 2°F. Sensitivity +/- 1/4°F. *: Performance based on 60 Hz operation and +80°F ambient air. For 50 Hz operation, refrigeration and air flow performance will be approximately 17% less. (.8333)
