BANGSON Mini Freezer, 1.1 Cu.ft Upright Freezer With Removable Shelf, Single Reversible Door, Compact for Home, Kitchen, Office, Apartment (Silver)

Llego muy bien empacado, funciona excelente.

I’ve been testing this freezer for six months and it is very well engineered and constructed. You never know what the failure rates are on these types of products but I believe it’s clearly a five-star mini freezer. It has 1.1 cu-ft of space with 2” thick walls and a 8°F to -7° freezer thermostat. Mini dorm fridges are generally the same size but have 1.6 cu-ft of space with only 1.2” thick walls and a refrigerator thermostat. The L35C5L is a fairly common, good quality compressor that runs at a lower power than the other freezers and fridges I looked at. The compressors in other small freezers are over-powered for such small appliances and overshoot when bringing the temperature down. The thermostat on this model like most of course doesn’t have a frost-free cycle, so it will build up frost every few weeks. I purchased both silver and black units over several months. They were packed extremely well and arrived in excellent condition without a scratch. The evaporator coils are well-placed throughout the walls, ceiling, and floor. It is more energy efficient and has a slightly quieter hum than other dorm fridges I’ve used, although the relay does produce a very light “click” sound two or three times an hour when it powers on and off. At 77° F ambient, it cools down faster than 2° per minute from room temperature which is excellent. It draws 7A on start-up and 0.7A while running the compressor for generally 5-15 minutes per hour. I would buy it again (and I did). —-------------------------------- MORE THAN YOU PROBABLY WANT TO KNOW I bought it to convert from a freezer to a well-insulated higher precision refrigerator (because of the thick insulation). Mini freezers come with a capillary tube type of thermostat that can be replaced fairly easily with one that has a refrigerator range. The replacement (such as a WPF-18) however will not provide as precise or consistent temperature range as I’d like, (better than 8-10°F). This was quite an undertaking requiring modification and a lot of testing. I did not anticipate that changing one setting in such a small appliance would produce such dramatically different temperature results, or a cycle that increased from 21 to 33 min with very very light frost. I was lucky to have found sweet spots for a stable temperature, reasonable temperature range for its size, and long cycle time. All of the mini freezers available have a similar design with different compressors, thermostat, and/or slightly different sized panels. I liked this one the best for its well-matched compressor, solid construction, and even distribution of evaporator coils. Customer service was also very friendly and wrote me back immediately. After the modifications below, I was able to achieve my desired average temperature of 32F (empty) even though the air temperature does fluctuate some, with a range of about 27.5-34.5F, turning on for about 3 minutes during each 33 minute cycle. Adding contents and/or additional ballast(s) will increase stability and narrow the temperature range more. Its long cycles will reduce the number of starts -which is responsible for most of the wear on a compressor. I plugged the appliance into a Johnson Controls A421-ABC temperature controller instead of using the built-in capillary thermostat. It is set to turn on/off at 33/30F. Many of the 1.1 cu-ft freezers sold on Amazon use a 95W compressor but the Bangson’s (L35C5L) is only 65W, which is actually still slightly overpowered for this small appliance. After the compressor shuts off, the evaporator coils are so cold that the fridge temperature continues to fall an amount equal to what it dropped when the compressor was running, (known as “overshoot”). The temperature probe for the A421 is mounted midway between the ceiling and floor, directly against the right wall almost against an evaporator coil, with a baffle shielding it from direct airflow except with an opening facing toward the door. The appliance itself is one big ballast so the probe basically follows the wall temperature. A 40 mm, 12V bearing fan powered with 5V is mounted at a 45° angle a few inches above the probe on the right side wall near the ceiling. It blows air at the ceiling towards the center, drawing air from the Johnson’s probe area below. This lightly circulates, improves temperature stability, and reduces overshoot. 5V was determined optimal for stability (and also lower noise) after trying 5, 6, 7, and 9V. (Aside from the door), the back wall and front of the compressor hump are the two places that don’t have evaporator coils. Ice packs offer slight improvement here as ballasts. Four thin 4.3" x 6.5 ice packs (or different-sized ones that fit each space in pairs) are placed horizontally. They generally come filled with low freezing point liquid (unfortunately designed for lower temperatures) and can either be topped off (sometimes 20% or more) or refilled completely with pure distilled water. The ballasts provide only incremental benefit compared to the other items in the system, but contents added to the appliance will improve the “ballast effect”. A 2” thick, 13.5” x 13.75” piece of Formular XPS insulation with ½” routed out (leaving the edges) will form-fit on the square protrusion of the inside of the door. Adding this additional 1.5-2” of insulation will further insulate and seal the door, improving efficiency by 10-15% or more. A Govee H5108 temperature probe is mounted in the center of the appliance on the front of the compressor hump midway between the floor and ceiling. It sends an internet alert (via Bluetooth) through its Govee H5151 bridge) to its phone app if the fridge’s temperature goes out of range. It retains logs that are easily viewed as graphs. An Ambient Weather WS-16, Supco DVT4, and Winland TC-2HL are other possible measurement tools. Bon Appetite.

K puede ser muy recomendable para los pequeños negocios.

Freezer is slightly noisy. Shipping box was in rough shape. Lots of holes, had no bottom, only styrafoam and bands taped all the way around holding the box together. Poor patch job on the back of the freezer. Due to the patch i was unable to reverse the door. So far the freezer is working fine. Seller was excellent! They gave me a 100% refund.

Tardan mucho en la entrega y llegó averiado, hubo derrame de aceite y un tubo estaba roto. No me hicieron efectiva la garantía, es una desventaja comprar estos tipos de productos.
