Undercounter -86°C ultra-low temperature freezer DW-HL50 has a little body for great use. It is designed to store low-temperature scientific experiments, plasma, tunny, biomaterial, and other biological products. This mini deep freezer can be applied to hospitals, blood banks, university laboratories, electronic industries, research institutes, military industries, pelagic fishery companies, sanitation, and anti-epidemic. With the microprocessor-based temperature controller, you can set the temperature range of -40℃~-86℃. The upright type and galvanized steel sheet(stainless steel optional) interior material helps it be cleaned easily. This small ultra-low temperature freezer provides a secure alarm system with keyboard lock and password access.


Microprocessor-based Temperature Control System

The microprocessor-based temperature controller system allows the -40℃~-86℃ temperature range to be set freely.
At an ambient temperature of 32℃, you can set the lowest temperature as -86℃ and make sure the precision of each 0.1℃.


Super Safe Alarm System

This under-counter ultra-low-temperature freezer has a lockable door to prevent unauthorized access. It also has a delayed start and safe stop interval between restart and termination.
The small deep freezer is equipped with an audible and visual alarm system, including a power failure alarm, a high/low-temperature alarm, a door ajar alarm, a communication failure alarm, a high ambient temperature alarm, and a sensor failure alarm.


Human-oriented Structure Design
The four casters make the freezer easily handleable.
Its front lockable door provides VIP Plus vacuum insulation, which can maintain temperature uniformity and avoid overheating.
The foaming design is with 110mm foaming insulation to promise better temperature performance.
