Energy Efficiency Revolution: Direct Cooling Eliminates Intermediate Losses

 1. Direct cooling technology achieves over 30% higher cooling energy transfer efficiency compared to indirect brine-based ice making by allowing refrigerant to directly contact ice molds. 2. Brine-based ice production requires maintaining an additional brine circulation system, resulting in significant energy waste, while direct cooling equipment consumes only 60 kWh per ton of ice—40% less energy than traditional systems.

Environmental safety: Eliminating the risk of brine pollution

Brined ice production requires regular brine replacement, which can corrode equipment and pollute water quality. Direct cooling systems use eco-friendly refrigerants with no brine leakage risk, meeting food industry safety standards.

Intelligence and low maintenance costs

Direct cooling equipment integrates functions such as automatic water addition, de-icing, and fault warning, reducing manual intervention, while brine ice making requires regular maintenance of the brine system, with corrosive media leading to a higher failure rate.

Stronger scene adaptability

Space flexibility: The direct-cooling modular design occupies only 50% of the space required by traditional equipment, making it suitable for fishing vessels, mobile cold chain, and other scenarios. Extreme environment stability: The direct-cooling system has a failure rate of less than 1% in high-temperature and high-humidity environments, whereas brine systems are prone to failure due to salt crystallization.

Long-term economic advantages

Although the initial investment for direct cooling is slightly higher, the payback period can be shortened to 8 months considering the savings on electricity bills, reduced maintenance costs, and extended equipment lifespan.
