Overview

Upright style Ultra-Low Temperature Freezers are designed for a variety of uses including shrink fitting, and ultra cold storage of product at -85°C. The upright freezer style allows for easy access and storage. Freezer Sizes range from 13 to 30 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. So-Low Ultra-Low freezers are available in wide variety of sizes and styles, to accommodate for each customers required conditions. Combined with our nation-wide service network, our Ultra-Low Freezers have various options for additional temperature recording devices, providing the highest level of quality temperature transcription.

So-Low's 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.

So-Low's 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.

So-Low's 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 is your assurance of So-Low Ultra low freezers' dependability. Every freezer is fully tested under the most demanding conditions for seven days. The constant ultra-low setpoint operation 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 Ultra Low Freezers are manufactured at the time the order is placed and go through extensive testing before they are released. A 4-6 week lead time should be expected.

Some of the accessories/options available for this product are factory installed and must be purchased at the same time your So-Low freezer / refrigerator is ordered. Please add them to your cart with your freezer / refrigerator before checkout so that they may be included with the submission of your order to the manufacturer for installation during production.

FAQ

What side does the door open from?

The door opens from the left side (the hinge is on the right), as in the picture below. If you need it the other way around, please inquire about having the door customized.

Are the So-Low Ultra Low Upright Freezers UL listed?

No, but they are ETL listed, which is a legally equivalent 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.

 

What is the weight capacity of each shelf?

75 pounds.

 

Do the So-Low Ultra Low Upright Freezers have a lock?

The latch of the freezer is lockable with a padlock. They do not have a built-in keyed lock.

 

What insulation is used and how much is there?

The insulation is a 5 inch thick polyurethane foam.

 

What is the life expectancy of one of the So-Low Ultra Low Upright Freezers?

If a freezer kicks the bucket, it's probably because the compressor went. So this is really a matter of how long the life of the compressor is. The manufacturer of these compressors puts them through a stress test which simulates, in an accelerated fashion by means of having additional load on it, 8 years of normal wear. According to this test, a So-Low ULT should last at least 8 years.

However, there are situations where you can decrease the life of your compressor. Most of these involve additional stress on the compressor, for instance:

  • Opening and closing the door frequently
  • Having the unit in a hot and / or dirty environment
  • Not cleaning the area around the compressor and allowing dust to build up on the components
  • Not replacing worn door gaskets, if necessary

So under heavy load, in a harsh environment or under conditions of poor maintenance, your ULT might not last as long. This would be true for any freezer.

 

What refrigerants are used in the So-Low Ultra Low Upright Freezers?

R-404A, R-508B, and R-170.

 

Are these refrigerants acceptable under the EPA's Significant New Alternatives Policy (SNAP)?

Yes, they all are listed as acceptable under the EPA's Substitutes in Very Low Temperature Refrigeration.

Fun toy for fetch
Size: Medium, Number of Items: 1
Daisy loves this toy. I found it from her dog trainer, and it makes rewarding her with a quick tug of war and fetch really easy. Also it’s shockingly durable. It looks like foam, but she has not destroyed this one.

Definitely recommend, great product!
Color: Grey
Absolutely amazing and great quality. My two chihuahuas have been digging and ripping up potty pads since they were babies. They are now 1 year and 3 months old and still do that. I tried reusable potty pads for a while and washing them, but eventually the smell and amount of time wasn’t worth it anymore. And I was looking for something else. I found these and ordered 3 of these potty trays and they are incredible. They can’t chew the disposable potty pads and they do great with this. I highly recommend! It took about 3 days for them to adjust to the feeling of the material but now they are comfortable. I wipe the top daily and change the disposable potty pads. Then once a week I clean with vinegar and water and towels or just soap and I sometimes spray down with hose outside. It makes it much faster and easier. It still takes work to keep it clean but it’s much better than cleaning up ripped up potty pads every day. It’s a great value also for the price and definitely I can tell is going to last a long time. For reference my dogs are 10 pounds, they are overweight right now and loosing weight, but this completely holds them and is very sturdy, even when both are on it at the same time. They use as their main bathroom area as it is not safe for them to go outside alone because there are coyotes in the area. And when I’m at work they have access to a potty area all day. I definitely recommend for dogs this size and am so happy I found a product that works for my home. Also the grey color is great and matches well in my home.

Absolute LIFESAVER.
Color: Black
A must-buy for any puppy owner that uses potty pads. Our pup still hasn't had all of her parvo boosters and has had to stay inside at all times. She is usually very good about going on her potty pads, but has a terrible habit of grabbing the pad and flinging waste everywhere and tearing the pad itself apart. This potty pad holder is PERFECT. It is sturdy and the grated tray fits in neatly. The dog is unable to get to the puppy pad, no matter how hard she bites or paws at the sides. Believe me, I've seen her try. We bought other puppy pad holders that were cheaper, but she was able to rip the puppy pad out of them easily. It is also really easy to clean. The plastic can easily be washed with soap and water or sprayed and wiped with antibacterial spray. The potty pad itself usually soaks up all of the urine, so there is never any worry of overflow. The only critique I have is that the rectangular shape is somewhat a poor design, because most potty pads are square-shaped. This means that the owner has to fold a standard potty pad in order to fit the tray. But this is not a huge problem, as we're still very happy with the product. Overall, it's worth the money, because now I don't have to worry about cleaning a huge mess, disciplining my pup for the behavior, or any health scares from her eating plastic from the potty pads. We loved the first one so much, that we bought a second one.

Perfect for what we need!
Color: Black
Love this. We have to leave our puppy home alone while we are at work. She’s tiny so I know she can’t hold it in the entire time we’re gone and I knew she would tear up the puppy pads. I came across this and it has been a game changer. She goes right on and does her business. One negative is when she only puts her front paws on and pees while half on the floor but that’s a quirk of the dog. The main negative is that if she poops, it’s sometimes hard to get it up and it gets in the holes. Plus is it’s easy to take apart and hose off. Definitely recommend!
