-40⁰C Upright Freezer LUF-B50

Labtron’s -40?C Upright Freezer LUF-B50 is equipped with multiple alarms—covering high/low temperature, door ajar, power loss, condenser overheating, ambient temperature rise, and sensor faults—to promptly alert users to any condition that could threaten stored materials. Its microprocessor-based control system ensures accurate temperature regulation (±1?°C) for stable preservation. Durable PCM-coated steel construction enhances insulation and resists corrosion for reliable long-term use. Manual defrosting prevents abrupt temperature changes, common in automatic defrost units. Levelling feet maintain freezer stability, minimizing risks like tipping or gasket misalignment.

The -40?C Upright Freezer LUF-B50 is optimized for energy efficiency, operating at just 2.5?A, 220?V, and 115?W to reduce electricity costs. It utilizes R290 refrigerant, an eco-conscious and high-efficiency cooling agent that lowers environmental impact. The manual defrost system helps maintain consistent energy usage by avoiding the high loads caused by automatic cycles. PCM-coated interiors support better cold retention, easing the compressor's workload. Its space-efficient 106?L storage avoids energy waste from underutilized capacity.

Yes, the -40?C Upright Freezer LUF-B50 is built to operate across dual voltage systems, making it suitable for lab environment. This enables smooth transition of temperature-sensitive samples between international locations. It integrates into labs with mixed voltage setups, operating within the safe limits of standard electrical circuits. Plug-and-play adapters eliminate the need for complex installation, offering quick and easy setup without additional hardware.

To maintain peak performance, the -40?C Upright Freezer LUF-B50 should be manually defrosted once frost accumulation exceeds 5?mm. Regularly cleaning condenser coils and fan components every 3 to 6?months prevents overheating and mechanical stress. Keeping the unit level ensures the door seals remain tight and effective. Gasket inspections should be done frequently, with prompt replacement if cracks or wear are observed. Test alarm functions during simulated outages to verify system reliability and preparedness.

The -40?C Upright Freezer LUF-B50 includes an integrated microprocessor with LCD readout but lacks built-in USB or Ethernet ports. For remote monitoring, external data loggers or lab monitoring systems are required. While the freezer’s standard alarms are both visual and audible, they do not transmit alerts remotely. However, users can connect alarm relay outputs to third-party IoT devices, enabling extended remote monitoring capabilities and enhancing unattended lab safety.

Yes, the -40?C Upright Freezer LUF-B50 operates with a sound level of just 58 dB, which is quieter than many standard lab appliances. This low-noise design helps maintain a peaceful working atmosphere in laboratories, clinics, and academic settings. It's ideal for shared or open-plan lab environments where noise reduction is essential. A quieter unit also supports uninterrupted concentration for researchers during long working hours. Despite its silent operation, it delivers powerful and consistent cooling performance. The reduced noise is a result of optimized compressor design and insulation.
