Overview

Chest style Ultra-Low Temperature Freezers are designed for a variety of uses including shrink fitting, and ultra cold storage of product down to -85°C. The chest freezer style allows for efficient storage. Freezer Sizes range from 2 to 27 cubic feet capacities.

Manufactured in Cincinnati Ohio, So-Low Ultra-Low -85°C freezers are produced with high quality craftsmanship, heavy-duty materials, and over 50 years of experience. These freezers use a cascade refrigeration system, providing reliable and durable environmental conditions for your product’s vital temperature requirements. Available in wide variety of sizes and styles.

Superior Construction

Ultra low freezers have a 16-ga. exterior (cold rolled steel). Interiors are 14 gauge vs. competitions 16 gauge.Ultra low freezer interiors are galvanized, non-corrosive steel. Galvanized steel conducts temperature more efficiently than stainless steel. This creates less stress on compressors making them run cooler and longer.

Digital Control

So-Low is the only ultra low temperature manufacturer to utilize a dual display digital temperature control. A red LED display indicates the actual interior chamber temperature while a green LED display located directly below the red display shows the actual setpoint temperature. This will give assurance that the freezer is operating at the correct temperature range whereas other manufacturer's temperature controls show only the actual temperature and not both the setpoint and actual temperature.

Dependability

Laboratory professionals all over the world have recognized the dependability and efficiency of So-Low Ultra Low Freezers, the first to combine all of these performance features and deliver a level of quality construction, reliability and value unequaled anywhere in the world. Performance testing: every freezer is fully tested under the most demanding conditions for seven days. The constant ultra-low setpoint operating temperature is assured in warm temperature environments. Dependability is backed up by a 12 month warranty.Technical assistance is provided by a Nation-Wide-Network of service companies.

Please note: So-Low refrigerators and freezers are manufactured at the time the order is placed and go through extensive testing before they are released. A 2-3 week lead time should be expected.

 FAQ

What is the temperature stability of the C85 Series Chest Freezers?

The temperature stability is +/- 3°C. For example, if you set the temperature to -80°C the compressor will engage at -77°C then turn off again at -83°C. This is done such that the compressor has some "off" time between cycles and reduces wear on the compressor, thereby extending the life of the freezer.

 

Can the chest freezers be placed on casters? Are the casters included and pre-installed?

Yes, all of the So-Low ULT chest freezers come with casters pre-installed.

 

What does the warranty cover? Is there a longer warranty on the compressor? there an extended warranty available?

The warranty is a 1-year parts & labor warranty, which includes the compressor. Extended compressor warranties are available for purchase which extend the compressor warranty for 4 years (5 years total from date of purchase) but the extended warranty covers parts only, not labor. Extended warranties must be purchased at the same time as the freezer. Please contact us for pricing information.

 

Are the So-Low Ultra-low Chest Freezers UL listed?

No, but they are ETL listed, which is a similar marking from a different organization. Just like UL listing, ETL listing serves as proof of product compliance to North American safety standards in both the US and Canada.

 

Do the So-Low ULT Chest Freezers Come with a locking mechanism?

The latch to close the door has a space for a padlock or combination lock to be inserted. There is not a keyed lock built into the freezer.

 

If the gaskets need to be replaced, can we order replacement gaskets? Is installation of new gaskets a complicated procedure?

Yes, replacement gaskets are available. There are two gaskets - one in the lid and one around the body where the lid makes contact with it. Installing them requires use of a staple gun and adhesives. If you're handy, or you have facilities staff at your institution, you can likely install the replacements yourself.
