The MTST DW-135W58 is an ultra-low temperature laboratory freezer that operates down to -135°C, intended for cold storage and low-temperature testing in research and industrial settings. The 58 L interior is built from 304 stainless steel and reaches deep cryogenic temperatures for sample preservation.

It is suited to laboratories storing biological materials and to electronics or materials testing that requires very low temperatures. A door lock prevents unintended opening, and heavy-duty casters allow the unit to be repositioned within a facility.

The freezer uses computer-based temperature control and an EBM silent fan, with an inner chamber of 410×410×385 mm and external dimensions of 670×765×1025 mm.

How It Works

The unit uses a single-stage autocascade compression refrigeration system with a CFC-free mixed refrigerant to reach its low operating temperatures. Computer-based temperature control regulates the chamber, while manual defrost is used to clear frost accumulation.
