- 30℃ freezing system : UD-30L500 / UD-30L1125

• Excellent freezing function enables long-term frozen storage - Cold storage at up to -30℃ allows long-term storage in medical and biological fields.
• Automatic shutting door - Application of an automatic shutting door can reduce unnecessary heat loss, and in case that the door is not shut owing to outside interference, indication and warning sound will be ringing.

- 40℃ freezing system : UD-40L500

• Inside door - A door that will prevent the rapid cooling of inside temperature of furnace by the outside air when the outside door is open.
• Vacuum relieving system - When opening door again immediately after opening closing, it enables you to open easily by relieving internal negative pressure.

Common Facts

• Door switch - If the door is open for more than 30 sec, 3 times of alarm sound will be initiated and if the door is not closed afterward, repeated warning sound will be generated to prevent unnecessary heat loss.
• Door locking device - A door locking device is basically built in to keep contents safely so it is convenient to use.
• Environment-friendly new refrigerant - Avoid to destroy the ozone layer and less caused air pollution.
• High density polyurethane technology - It minimizes internal and external heat loss through excellent insulation so reduces unnecessary power consumption.
• Compressor with high-efficiency - In order to maximize cooling performance, compressor with high-efficiency is applied that plays an important in supplying cooling air without delay when it needs. That is why it allows end-users to use efficiently.
• Digital controller(Temperature range -30~-10℃ / -40~-20℃) - Beautiful and ergonomic design, and the display showing the function and the condition of tissue at a glance provide more convenience in using the product.
