Features

Stable Temperature Control

Using SANYO microprocessor technology the MDF series provides precise and uniform storage temperatures regardless of ambient conditions, with a settable temperature range from -20°C to -30°C in 1°C increments. Built-in alarm and product safety functions are also provided as standard features.

Sample Protection Functions

Digitally Adjustable Temperature Setpoint, High and Low Temperature Alarm, Door Ajar Alarm, Remote Alarm Contacts, and Non-Volatile Memory Backup. Both visual and audible alarms are standard.

Quiet Operation SANYO’s energy-efficient refrigeration design requires no noisy condenser fan. In combination with low dB level compressor, this unit is uniquely quiet and perfect for in-lab installations.

Easy Maintenance

Natural cooling of the unit’s condenser eliminates the need for a condensor fan. Periodic cleaning of a filter is therefore not required, making periodic maintenance minimal. Standard castors and leveling feet make relocation easy.

SANYO Refrigeration

Sanyo designed and built rotary compressor offers high performance, reliability and peace of mind. Heated mullion under door gasket prevents frost build up.

Sample Storage Security

Standard keyed door lock and integrated padlock hasp are standard features.

Adjustable Shelving System

Four adjustable wire shelves with over 100 pound capacity each allows for flexible material storage configurations.
