-86°C PRODUCT FAMILY

A wide range of Ultra-low temperature freezers.

This product family offers different types and models of ultra-low freezer which can achieve and maintain temperatures down to -86ºC (-123ºF) at ambient temperature of 30ºC (85ºF). It is a wide selection, offer- ing a variety of sizes and types suitable for uses such as long term preservation, testing, frozen storage etc.

Specially Designed Compressor for Ultra-Low Temperature.

The refrigeration system is at the heart of producing ultra-low temperature freezing. In the process of developing various technical solutions in order to achieve and maintain ultra-low temperatures, Sanyo designed a compressor especially for ultra low-temperature use. Sanyo is a leading manufacturer of ultra-low temperature freezers that develops and produces all its own components, from the refrigeration units to the microprocessors.

An Ideal Freezing Environment By

and the “Hot Line”.

In Ultra-Low temperature freezers, effective insulation is extremely critical since the temperature difference between the outside and the inner compartment

DESIGN

can be as high as 115ºC. The insulation used in Sanyo’s ultra-low temperature freezers is two layers of rigid,

foamed in place polyurethane. This design prevents the insulation layers from distortion and cracking that might occur due to temperature differences inside and out, and creates the most efficient insulation material available today. Moisture condensation at the top edges of the cabinet due to differences in temperature inside and out causes frost and icing problems, which may reduce heat insulation efficiency and obstruct door movements. They are prevented by the “hot line” by means of which hot gas from the higher temperature circuit is circulated through the problem areas.

Evolutionary Design

■The newly developed refrigeration system and freezer structure minimizes intrusive operating noise.

■The newly developed back cover combined with new aerodynamically designed and placed components in the refrigeration compartment provide supe- rior air flow, making it possible to drasti- cally reduce the stress to the freezer and contributing to excellent durability.

■Two independent and insulated inner doors ensure maximum interior chamber uniformity.

Safety

■High and low temperature warning pro- vides an audible and visual alarm when the temperature deviates more than ±5°C to ±20°C (adjustable) from the set point.

■Alarm ring back function ensures that buzzer will resume operation, should alarm conditions continue after it is silenced.

■Microprocessor-controlled filter-clog check function

protects the refrigeration circuit.

■Control panel with digital display for easy operation.

MDF-U5386SC, MDF-U7386SC specifications

The Sanyo MDF-U7386SC and MDF-U5386SC are sophisticated laboratory refrigerators designed to provide optimal storage conditions for temperature-sensitive biological and pharmaceutical products. These models deliver reliability, efficiency, and advanced technology, making them valuable assets in medical and research environments.

One of the standout features of both models is their precision temperature control system. They utilize advanced digital thermostats that allow users to set and maintain precise temperature ranges, typically between 2°C and 8°C. This capability is critical in ensuring that sensitive samples, vaccines, and other bio-products retain their efficacy and integrity.

The MDF-U7386SC and MDF-U5386SC are built with high-performance insulation to minimize temperature fluctuations. Their double-layered insulated walls help maintain a stable internal environment, while the powerful refrigeration system works efficiently to recover temperature quickly after door openings or power interruptions. This is crucial in laboratory settings where frequent access may occur.

Both models come equipped with a microprocessor-based control system that monitors temperature and operates alarms for potential temperature deviations, power failures, and door ajar conditions. This feature provides an added layer of security for valuable samples, alerting staff immediately to any issues.

The design of these refrigerators emphasizes easy access and organization. They feature adjustable shelves and a spacious interior that can accommodate various types of materials. Transparent door designs allow for easy monitoring without the need to open the unit, improving energy efficiency and temperature stability.

Sanyo incorporates environmentally friendly technologies in the MDF-U7386SC and MDF-U5386SC, including the use of hydrocarbon refrigerants, which have a lower environmental impact compared to traditional blowing agents while still providing effective cooling performance.

Maintenance is made effortless with self-diagnostic functions and user-friendly interfaces that guide users in operating settings and potential troubleshooting. The sleek design contributes to overall workplace aesthetics while ensuring that vital biological samples are stored in optimal conditions.

In summary, the Sanyo MDF-U7386SC and MDF-U5386SC laboratory refrigerators excel in temperature stability, efficiency, and user-friendly features. Their robust performance, coupled with advanced technologies, underscores Sanyo's commitment to supporting scientific research and healthcare with reliable temperature-controlled storage solutions.
