The ultra low temperature freezer offers a wide variety of research and storage applications, such as low temperature scientific experiments, preservation of plasm, biomaterial, tunny, biomedical products, and testing low-temperature-resistant properties of military products. It is suitable for blood banks, hospitals, sanitation and anti-epidemic stations, research institutes, electronic industries, chemical industries, biotechnology engineering, university laboratories, military industries, pelagic fishery companies, etc.

Forefront Refrigeration Technique

CFC-free refrigerant, invented by the Technical Institute of Physics and Chemistry, Chinese Academy of Science

Unique refrigeration loop and single stage refrigeration technology

Secondary foam insulation technology protects insulation layer from being damaged by low temperature,

International renowned brand “Danfoss” high-efficiency hermetic compressor, energy saving, quiet running

International renowned brand “E-bm” fan motor

CFC-free foamed polyurethane insulation. Extra thick thermal insulation layer and vacuum insulation panel provides better low-temperature preservation.

Advanced Control Technology

High-precision microprocessor control system. Platinum resistance temperature probe.

Adjustable temperature range from -10℃ to -65℃ with an increment of 1℃.

Digital display of temperature. Operator can monitor running state at any time.

Optional accessories: temperature chart recorder, backup battery, remote alarm indicate light, voltage compensator, and remote monitoring system.

User Friendly Design

Power-assisted door handle let the user open the door manually at a reduced force. (Chester Freezers: top open, balanced hinge is installed to the door for easy opening)

Adjustable shelves are convenient to store articles. (Upright freezers only)

Double door design minimizes cold air loss. (Upright freezers only)

Safety Control System

Keyboard locker and password-protected setting on control panel prevents parameters from being changed without authorization.

Protection functions like delayed start-up, delayed stop ensures stable running

Perfect audible and visual alarm for monitoring freezer conditions like probe failure, high temperature, low temperature, low battery, door open, clean filter, system failure, and so forth ensures the safety of storage.

Safety lock prevents unauthorized access.
