The DW-40L92 is an upright -40°C biomedical freezer, compact enough at 810 mm high to fit under a bench for under-counter installation. It is designed to store vaccines, blood plasma, and other biological materials, with installations found in research institutions and clinical sites across the life science, pharma, biotech, medical, and electronics sectors.
A hydrocarbon inverter compressor system delivers power consumption as low as 1.42 kWh per 24 hours, a reduction of more than 50% from the 3.3 kWh per 24 hours of earlier designs. The cabinet cools from 25°C ambient to -40°C in around 110 minutes.
A microprocessor electronic temperature controller with an LCD digital display offers 0.1°C precision, with an adjustable set point of -20°C to -40°C. A mechanical lock with a lock catch secures the door and can be padlocked, suited to multi-user environments.
Certified CE.
