Temperature Control > Microprocessor temerature control. > Digital temperature display > Ajustable temperature range from -126℃ to -150℃ with an increment of 1℃ Safety Control > Malfunction alarm includes audible and flashing alarms for high temperature,low temperature,incorrect voltages setting, sensor failure,condenser efficiency defect,high ambient temperature,and power failure. > Multiple level protections:password,compressor delay start,extra high and low pressure back up. > All separate parts are safely grounded. Cooling System > High efficient CFC-free refrigerant cooling system. > The boiler from up to down ensure the refrigerant flowing efficiently. > Excellent cascade cooling system with dual fan whose blade is designed according to aerodynamics. > The condenser fillter with removal and easily cleaning make sure the best cooling efficiency. Ergonomic Design > Applicable to use far away from the working ambient temperature within 10~25℃. > Gravis type added self-locked caster,it is convenient for moving. > Low temperature level compressor control only if need to avoid mistake for a longer life. > It is easy to wash because of Inner round angle dealing design. > Optional LN2 backup system makes it convenient to use under emergency situation,make the operation safe. > Optional temperature record instrument, so it is convenient to record temperature and save forever. > Optional intelligent monitoring system, you can record the data and monitor on the the computer and realize remote supervising.
