Commercial industrial refrigeration systems rely on components that have to match your cooling load. When you compare complete walk-in freezer kits, the compressor horsepower rating is often the first thing to weigh. Here, two new complete kits face off: a 4 HP model and a 3 HP model. Both are listed as new, custom-bundle walk-in freezer items from China, with a Dixell controller and 220V power requirements.
Quick Verdict
The immediate trade-off is between compressor horsepower and listed price. The two systems share the same general setup: new condition, Country of Origin China, Custom Bundle Yes, and a Dixell controller. So the real buying decision is whether your walk-in freezer refrigeration load needs 4 HP or can work with 3 HP. If you need more compressor capacity, the 4 HP model is the one to pick. If you want the lower listed price, the 3 HP model takes that side.
Comparison at a Glance
| System | Listed Price | Price Bar | Key Spec |
|---|---|---|---|
| 4 HP Walk-In Freezer Complete Kit | USD 5,120.00 | 4 HP compressor, Model W4HP, Dixell controller | |
| 3 HP Walk-In Freezer Complete Kit | USD 4,610.00 | 3 HP compressor, Model W30HP, Dixell controller |
Both kits are new, custom bundles from China. They also share the Dixell controller and 220V design.
Where the 4 HP Kit Wins
The 4 HP model gives you a higher compressor horsepower rating than the 3 HP option. For a walk-in freezer that demands more compressor capacity, this kit is the stronger choice. It is a complete refrigeration system with a 4 HP compressor, Dixell controller, and English instructions.
Where the 3 HP Kit Wins
The 3 HP model has the lower listed price of the two. If a 3 HP compressor is enough for your walk-in freezer, you get the same general kit structure-new, custom bundle, Dixell controller, 220V design-for less upfront.
Product Notes
NEW Walk-In Freezer Refrigeration Cooling System Compressor 4 HP Complete Kit

The 4 HP complete kit is the more powerful of the two listed compressor systems. It pairs a 4 HP compressor with a Dixell controller, 220V power requirements, and English instructions, all in one custom bundle. If your walk-in freezer refrigeration load is demanding enough to need 4 HP, this kit gives you that rating. The trade-off is the higher listed price in this head-to-head; you are investing more upfront to get the higher compressor horsepower rating.
NEW Walk-In Freezer Refrigeration Cooling System Compressor 3 HP Complete Kit

The 3 HP complete kit is the lower-priced option in this pair. It still arrives as a new walk-in freezer refrigeration system with a Dixell controller, 220V design, English instructions, and a custom bundle. If a 3 HP compressor is the right rating for your cooling load, this kit gives you the essential components without the higher listed price of the 4 HP model. The limitation is the lower compressor horsepower rating: you get 3 HP, not 4 HP, which makes it the less powerful choice between the two.
Final Choice by Use Case
Choose the 4 HP Walk-In Freezer Refrigeration Cooling System Compressor Complete Kit if your commercial industrial refrigeration setup requires a 4 HP compressor. Choose the 3 HP Walk-In Freezer Refrigeration Cooling System Compressor Complete Kit if a 3 HP compressor is the right fit and you want the lower listed price between the two.
