Unlike traditional brine systems, a direct cooling block ice machine uses refrigerant that flows through aluminum evaporator plates in close contact with the ice molds. This approach improves heat transfer, reduces energy use, and produces solid, uniform ice blocks. ICESTA has focused on this technology because it offers consistent ice quality and simpler maintenance for commercial ice production.
Precision Aluminum Welding for the Evaporator
The evaporator is the most critical part of any block ice machine. At ICESTA, all evaporator welding is done with strict standards. Seams are kept sealed, smooth, and tight because any small gap can affect cooling performance and ice quality. Welding quality also helps prevent refrigerant leaks and ensures even freezing across the entire ice mold.
Frame and Refrigeration Assembly
Once the evaporator is ready, it is assembled with heavy-duty frames, slide rails, and cooling pipes. This step forms a complete ice-making unit that can handle daily lifting, tilting, and ice harvesting. The frame is designed for 24-hour continuous operation, making it suitable for busy ice plants and industrial users.

Full System Testing with Bitzer Compressor
The compressor plays a major role in the long-term reliability of a block ice machine. This 20-ton unit is driven by a Bitzer compressor, known for steady and efficient operation. After assembly, the entire system is tested to verify cooling capacity, electrical safety, and automatic control functions before the machine is approved for packing.
Strict Quality Inspection Before Shipping
Each production stage is inspected separately before final assembly. Welding, refrigeration assembly, wiring, and system performance all undergo checks. Only machines that pass every inspection are allowed to leave the factory, which helps reduce on-site failures and improves overall return on investment.
Small seafood processing businesses
Food production facilities
Concrete cooling projects
Local ice distribution
A 20 ton block ice machine is more suitable for:
Large-scale ice factories
Fishing ports and wholesale markets
Industrial cooling operations
Companies planning to expand production
A block ice machine is a long-term investment. The quality of welding, components, and assembly directly affects:
Ice quality: Properly sealed evaporator welds produce cleaner, more uniform blocks.
Energy efficiency: Smart controls and efficient compressors reduce power consumption per ton of ice.
Operational uptime: Strict inspection and quality parts minimize breakdowns and lost production.
That is why ICESTA keeps all major production steps in-house and welcomes customers to visit the factory and see the process in person.

If you need an ice machine 10 ton system or a larger 20-ton block ice machine, ICESTA can provide a configuration that matches your ice production goals. Our team supports you through sizing, installation planning, and after-sales service.
Q1: How much ice can a 10-ton block ice machine produce per day?
A: A 10-ton block ice machine typically produces about 10 tons of ice in 24 hours under standard conditions. Actual output may vary with ambient and water temperatures.
Q2: What is the difference between direct cooling and brine systems?
A: Direct cooling places aluminum evaporator plates in direct contact with ice molds, improving heat transfer and reducing corrosion compared with brine systems. It also allows a more compact design.
Q3: Can I monitor the ice block maker machine remotely?
A: Yes, ICESTA block ice machines can be configured with remote monitoring, so you can view operating status and alarms from your phone.
Q4: What brand of compressor does ICESTA use?
A: Many ICESTA machines, including the 20-ton model, use Bitzer compressors for stable and efficient refrigeration.
Q5: Can I visit the factory before purchasing?
A: Yes, ICESTA welcomes customers to visit the factory and see the production process in person.
