Product Features
- The interactive touchscreen interface is simple and convenient to operate;
- 7-inch LCD touchscreen display;
- The exterior uses high-strength cold-rolled steel with a powder-coated surface;
- 304 stainless steel chamber;
- The stainless steel shelf supports are height-adjustable and freely removable for easy chamber cleaning;
- The cabinet insulation uses integral foaming with high-density R245fa polyurethane. The 126mm foam layer has an extremely low thermal conductivity for greater energy savings. R245fa is an environmentally friendly foaming agent with high flame resistance and low flammability for greater safety;
- The ergonomically inspired door handle has a long lever arm, allowing one-handed opening;
- A mechanical lock and padlock hole are provided;
- Reinforced shelves support a maximum load of 50kg per shelf;
- A backup battery continues to power the display during a power failure;
- Internal/external pressure equalization valve;
- Anti-condensation function;
- Foam-insulated inner doors;
- Heavy-duty leveling casters;
Three-Level Access Management
- Multiple accounts with assignable access permissions are available. Controller permissions can be assigned to administrator, operator and guest accounts according to equipment management requirements;
Data Recording and Remote Control
- Temperature records can be exported through the USB port on the panel;
- Remote alarm connection provided;
- 485 interface provided;
Alarms and Protection
- Audible and visual alarms are provided.
- Comprehensive alarms include power failure, high/low temperature, low battery, filter cleaning required, sensor failure, refrigeration system failure and prolonged door opening;
- Comprehensive protection includes start-up delay and compressor overheating protection;
- Alarm records: all fault alarms and warning indications are fully recorded and can be downloaded for review;
- Backup battery: after a power failure, a fully charged backup battery provides real-time chamber temperature display and power-failure alarm information for at least 48 hours;
- Self-diagnosis: the display indicates the corresponding fault if the ultra-low temperature freezer malfunctions;
