Product notes

NEW Walk-In Freezer Refrigeration Cooling System Compressor 4 HP Complete Kit

NEW Walk-In Freezer Refrigeration Cooling System Compressor 4 HP Complete Kit

At the upper end of the price range, this 4 HP freezer kit is the higher-priced complete unit in this comparison. It's listed as a custom bundle, model W4HP, and the description mentions a Dixell controller and updated English instructions. That controller is included, so you don't need to source it as a separate part. If you want a 4 HP freezer package that comes as a kit, this is the direct choice. The trade-off is the price, which is above the 3 HP options, so the extra horsepower comes with a higher upfront cost.

NEW Walk-In Freezer Refrigeration Cooling System Compressor 3 HP Complete Kit

NEW Walk-In Freezer Refrigeration Cooling System Compressor 3 HP Complete Kit

This 3 HP freezer kit shares the W30HP model with the walk-in cooler unit but is specified as a walk-in freezer. It also comes as a custom bundle and includes a Dixell controller. The lower listed price places it at the bottom of the price range for freezer kits in this comparison, which is helpful when you want a complete package at the lower end of the price range. The limitation is the 3 HP motor, which is less powerful than the 4 HP options in this set, so it trades some raw capacity for the lower listed price.

NEW Walk-In Cooler Refrigeration Cooling System Compressor 3 HP Kit W30

NEW Walk-In Cooler Refrigeration Cooling System Compressor 3 HP Kit W30

This kit is for a walk-in refrigerator rather than a freezer. It has the same model number W30HP and is also a custom bundle with a Dixell controller. If your space needs cooler temperatures instead of freezer temperatures, this is the one product that matches that use case directly. The trade-off is that it addresses only refrigerator duty, so it's not a match for freezer applications, and the 3 HP output is on the lower end of this group.

4 HP Walk In Freezer Refrigeration System Compressor Condenser 220V Single Phase

4 HP Walk In Freezer Refrigeration System Compressor Condenser 220V Single Phase

This is the only system carrying the Elite Kitchen Supply name. The description includes ETL certification, a temperature range from -8°F to 41°F, and a warranty of one year on parts and two years on the compressor. It's described as a 4 HP walk-in freezer system with a single-phase 220V condenser. If you want a branded system with those stated protections, this is the match. The limitation is the highest listed price in the comparison, and the 4 HP output is the same as the other 4 HP kit but at a slightly higher price.

Final recommendation

If you need a complete 4 HP freezer kit with a controller, go with the NEW Walk-In Freezer Refrigeration Cooling System Compressor 4 HP Complete Kit. For a lower-priced 3 HP freezer kit, the NEW Walk-In Freezer Refrigeration Cooling System Compressor 3 HP Complete Kit is the choice. If your space is a walk-in cooler rather than a freezer, the NEW Walk-In Cooler Refrigeration Cooling System Compressor 3 HP Kit W30 covers that duty. And if you want a branded 4 HP system with ETL certification and a stated warranty, the 4 HP Walk In Freezer Refrigeration System Compressor Condenser 220V Single Phase is the one to consider.
