Product Specification Sheet
Deep Freezer -20°C
Model Number: MT-326
The Deep Freezer -20°C from Micro Technologies is a low-temperature laboratory storage system designed for controlled preservation of suitable samples, reagents and research materials. Available in vertical and horizontal configurations with capacities ranging from approximately 112 to 340 litres, it features a stainless steel inner chamber, high-grade PUF insulation and microprocessor-based PID digital temperature control.
Product Specification
The Deep Freezer -20°C is designed to provide controlled low-temperature storage for laboratories, research facilities, testing centers and other applications requiring temperatures down to approximately -20°C.
The unit features a double-wall construction. The outer body is manufactured from powder-coated mild steel or stainless steel, while the inner chamber and trays are manufactured from stainless steel sheet for durability and convenient cleaning.
The space between the inner and outer walls is filled with high-grade PUF insulation. This insulation helps minimize thermal loss and supports efficient maintenance of the required internal temperature.
A transparent acrylic inner door allows users to view the contents of the chamber while reducing unnecessary exposure of stored materials to external conditions.
The unit is fitted with a microprocessor PID-based digital temperature indicator-cum-controller, providing convenient setting and monitoring of chamber temperature. The specified operating temperature extends from ambient conditions down to approximately -20°C, with an indicated accuracy of approximately ±0.5°C.
Both vertical and horizontal models are available, allowing laboratories to select the configuration best suited to available space and storage requirements.

Construction Features
Double-Wall Construction
The double-wall cabinet provides a durable structure while creating an insulated space between the outer body and internal storage chamber.
Stainless Steel Inner Chamber
The internal chamber and trays are manufactured from stainless steel, providing a durable surface suitable for regular laboratory storage applications.
High-Grade PUF Insulation
High-grade PUF insulation is provided between the inner and outer walls to minimize thermal loss and improve temperature retention.
Transparent Acrylic Inner Door
The transparent inner door allows users to inspect stored materials without unnecessarily exposing the complete chamber to room conditions.
Temperature Control System
Microprocessor PID Digital Controller
The freezer incorporates a microprocessor-based PID digital temperature indicator-cum-controller for setting, monitoring and maintaining the required chamber temperature.
Cooling Down to -20°C
The refrigeration system is designed to maintain chamber temperature down to approximately -20°C, making the unit suitable for a variety of low-temperature storage requirements.
Temperature Accuracy
The specified temperature-control accuracy is approximately ±0.5°C under suitable operating conditions.
Digital Temperature Indication
The digital display provides clear temperature indication for convenient monitoring during operation.
Vertical & Horizontal Configurations
Vertical Deep Freezer
The vertical configuration provides upright storage and convenient organization while using comparatively less floor area.
Horizontal Deep Freezer
The horizontal configuration provides chest-style storage and is useful where bulk storage and top access are preferred.
