Fisher Scientific Isotemp Explosion-Proof Laboratory Refrigerator/Freezer Combination

The Fisher Scientific Isotemp Explosion-Proof Laboratory Refrigerator/Freezer Combination is a laboratory-grade cold storage system engineered for the safe storage of temperature-sensitive flammable chemicals in hazardous locations where ignitable vapors may be present. With a combined storage capacity of 10.1 cubic feet (286 L), separate refrigerator and freezer compartments, and explosion-proof electrical construction, this combination unit provides dependable refrigerated and frozen storage while meeting the stringent safety requirements of chemical laboratories, pharmaceutical facilities, petrochemical operations, and industrial research environments.

Unlike flammable material storage refrigerators that are intended for non-hazardous laboratory spaces, the Fisher Scientific Isotemp Explosion-Proof series is specifically designed for installation in Class I, Division 1, Groups C and D hazardous locations. Spark-free interiors and exteriors, explosion-proof electrical components, manual defrost operation, and a CFC- and HFC-free refrigeration system help reduce ignition risks while maintaining dependable laboratory temperature performance. These units are hardwired directly into the building electrical system rather than utilizing a standard power cord for additional safety.

Many laboratories pair explosion-proof refrigeration with chemical fume hoods, biosafety cabinets, laboratory freezers, and laboratory refrigerators to create a complete hazardous-material handling workflow.

2. Functional Testing
• Power on the refrigerator and verify that display screens, alarms, and controls function properly
• Test door latches and sealing mechanisms to ensure secure closure and insulation
• Run preliminary temperature cycles to observe startup behavior and cooling response

3. Temperature and Stability Testing
• Test internal temperature sensors and controllers using thermometers/probes
• Monitor temperature at multiple points within the chamber over an extended period
• Verify accuracy across user-defined setpoints (e.g., +4°C, +2°C to +8°C range)

4. Cooling System and Compressor Evaluation
• Test compressor startup, cycling, and operating noise levels
• Inspect condenser coils and fans for proper function and cleanliness
• Check refrigerant pressure (if applicable) and confirm there are no leaks or system inefficiencies

5. Electrical Safety and Compliance Checks
• Ensure all internal and external electrical components are properly grounded
• Perform insulation resistance and leakage current tests
6. Final Quality Assurance Checklist
