Chest freezer LFZ-60W series

laboratory220 Vultra-low-temperature

Short description
Chest-type -60°C ultra-low temperature freezer designed for long-term storage of biological materials including viruses, bacteria, erythrocytes, leukocytes and skin. Suitable for blood banks, hospitals, epidemic prevention agencies, research institutes, industrial laboratories, biological engineering and marine fisheries.

Application

• Storage of biological products and temperature-sensitive physical/chemical materials such as blood plasma, vaccines and reagents.
• Suitable for hospitals, blood stations, public health and immunology services, chemical and military industries, electronics, animal husbandry, university laboratories and pelagic fisheries.

Advanced Cooling System
Fully covered evaporator, high-efficiency compressor and optimized condenser layout provide stable and efficient refrigeration.

Precise Microcomputer Temperature Control

• Microprocessor-based controller with digital temperature display; resolution 0.1°C.
• Adjustable internal range: -25°C to -60°C.
• Stable temperature control independent of ambient conditions; meets requirements for reagents, pharmaceuticals and samples.

Operating Security

• Alarm module monitors ambient and system status for safety and reliability.
• Alarms include high temperature, low temperature, sensor failure and power failure (power-failure alarm memory up to 48 hours).
• Two alarm modes: buzzer and flashing.

Avoid Falsification and Wrong Operation
Keyboard lock and password protection prevent accidental parameter changes.

Power Failure Protection
Delay-start function on power restoration prevents simultaneous startup of multiple devices and protects the equipment and power network.

Humanized Design

• Interior: SUS304 stainless steel; Exterior: painted steel.
• Wide voltage tolerance: 187V–242V.
• Lockable lid design to prevent unauthorized access.
• Large-screen display for easy reading.
