Defrost Method
Automatic
Features
- Forced air circulation ensures uniform conditions and rapid recovery
- Adjustable epoxy-coated wire shelves with optional drawer configuration
- Self-closing door with a 90° stop for secure storage
- Keyed on/off switch with setpoint security to prevent unauthorized changes
- Remote alarm contacts and optional 4-20 milliamp output for monitoring
- Icon-based control panel with a digital display for precise adjustments
- Audible and visual alarms with a push-button test function
- Heavy-duty casters with front locks for easy mobility and stability
User convenience is addressed through its icon-based control panel and a large, easy-to-read digital display that shows temperature variations within 1°C. The graphic thermometer indicator provides visual alerts for overtemperature and under-temperature conditions. Additional features include audible/visual warnings, a push-button alarm test, and a controller battery backup system. The freezer's construction is robust, featuring scratch-resistant cold-rolled steel interior and exterior finishes, and high-density, 2-inch-thick CFC-free urethane foam insulation, which guards against ambient temperature fluctuations. The CFC-free, HFC-blend refrigerant is environmentally friendly. The unit stands on four casters for easy mobility, with the front two being lockable.
All of our equipment is fully tested to perform at factory specifications before being shipped.

Recertification Inspection Protocol
- Inspect the display for pixel clarity and brightness, replacing any dim or dead pixels.
- Test all buttons for responsiveness, resistance, and durability; replace any that don’t meet standards.
- Check the door seal and lock for airtightness, replacing any compromised components.
- Run diagnostics on PCB test points for voltage and current accuracy, replacing faulty components.
- Verify compressor output and airflow, ensuring all internal fans function properly.
- Cross-check internal temperature probe accuracy with a NIST-traceable probe, recalibrating if needed.
- Inspect wiring for frays or tears, replacing compromised sections as necessary.
- Test the start capacitor's capacitance and replace if it’s outside the specified range.
- Replace all internal filters and thoroughly clean condenser fins for efficient heat dissipation.
- Verify the alarm battery holds a full charge and replace if there is any degradation.
- Operate the unit for 72 hours to confirm stable temperatures and operational consistency.
- Perform a final cosmetic check, repairing or touching up surfaces as needed for a professional appearance.
