Refrigeration

Cold chain refrigeration is a low temperature control supply chain system involving the whole process of food, medicine and other temperature sensitive items from production to consumption. In cold chain refrigeration, Sunwell fluid ice slurry system, cold chain cold storage transport. Heat exchanger products of Shen Technology: tube heat exchanger for fluid ice slurry system; Shen's tube heat exchanger, refrigeration heat transfer capacity, high reliability, used as a condenser in the fluid ice slurry system.

Solution

Fluid ice slurry crystals are very small, smooth and round, and they enter every corner of the product to be cooled. This allows for the fastest heat transfer, instantly and evenly cooling the product, and prevents potentially harmful bacteria formation, enzyme reactions, and discoloration. Fluid ice slurry maintains peak product freshness for longer.

Coaxial Tube Heat Exchanger for Fluid Ice Slurry Systems
Fluid ice slurry crystals are very small, smooth, and rounded, and they reach every corner of the product to be cooled. This achieves the fastest heat transfer, evenly cooling the product immediately, and prevents the formation of potentially harmful bacteria, enzyme reactions, and discoloration. Fluid ice slurry helps maintain peak product freshness for a longer time.
Heat Exchanger for Ice Making Bins
An ice machine is a refrigeration mechanical device that generates ice by cooling water through an evaporator with refrigerants from a cooling system. It uses a refrigeration system with water as the medium, and ice is produced when the system is powered on and processed by the equipment. Shen's coaxial heat exchangers are commonly used in ice machines as condensers, where the heat absorbed during ice making is expelled through the condenser via the cooling system.
Economizer
Coaxial tube economizer is actually a special heat exchanger, which is widely used in refrigeration and heat pump systems. The main role of the economizer is to increase efficiency in the system, especially in large commercial and industrial refrigeration systems.

Case Stories

Seafood Transport – Spoilage Reduced from 20% to Under 2%

A leading seafood exporter was losing 20% of inventory during long-haul transport due to slow, uneven cooling and bacterial growth. The installed fluid ice slurry system with coaxial tube heat exchangers achieved rapid, uniform cooling throughout the entire load. Spoilage dropped to below 2%, shelf life extended by 40%, and annual losses decreased by $500,000.

Pharmaceutical Cold Chain – Eliminated Temperature Excursions Entirely

A pharmaceutical distributor faced repeated temperature fluctuations outside the required 2–8°C range during vaccine transport over 1,000+ km routes, risking batch rejection and regulatory penalties. High-efficiency economized refrigeration units with precise heat transfer control were deployed. Result: temperature deviation kept within ±0.1°C, zero excursions or compliance issues recorded, and energy consumption reduced by 30%.

Food Processing – Cut Ice-Related Waste and Downtime

A large dairy processor experienced inconsistent ice quality and slow production cycles, leading to enzyme reactions, discoloration, and 15% waste of fresh milk batches. Ice-making bin heat exchangers were installed to optimize heat expulsion and produce uniform, round ice crystals. Ice production cycles shortened by 25%, waste fell by 18%, and plant uptime significantly improved within six months.
