Engineered to rapidly overcome the zone of maximum ice crystal formation (-1°C to -5°C), preventing cellular rupture and ensuring pristine textural integrity and weight retention in delicate marine catches.
Optimized for seafood deep-freeze warehouses with enhanced fin pitch to prevent rapid frost accumulation during high-moisture loading.
Constructed with food-grade hydrophilic fin coating, ideal for high-saline coastal seafood packing and rapid processing environments.
Designed for tuna, salmon, and pelagic blast freezers demanding sustained -40°C to -50°C evaporating performance with zero thermal drift.
Features dual-speed axial airflow and intelligent hot-gas/water defrosting to maintain 92-95% relative humidity for fresh catch storage.
The global seafood industry processes millions of metric tons of pelagic, demersal, and aquaculture yields annually. Marine protein is exceptionally vulnerable to autolytic enzyme degradation, lipid oxidation, and bacterial proliferation if temperatures fluctuate even within a fraction of a degree. Modern seafood logistics demand a seamless transition from harvest to ultra-low temperature preservation.
In aquatic processing facilities, conventional industrial evaporators often suffer from rapid frost bridging, uneven airflow distribution, and severe coil corrosion caused by salty, moisture-laden ocean air. Kabel Air Coolers by Kewei Cold are purpose-engineered to overcome these exact thermodynamic bottlenecks.
Over 25 years of specialized refrigeration manufacturing enables us to deliver unmatched thermal heat exchange efficiency, lower energy consumption (kW/ton of refrigeration), and exceptional operating reliability.
Engineered with mechanically expanded inner-grooved rifled copper tubing and corrugated aluminum fins. This configuration multiplies turbulence in the refrigerant boundary layer, boosting sensible and latent heat transfer coefficients by 32% compared to standard smooth tube designs.
Aquatic freezing yields high moisture loads that rapidly turn into dense frost. Kabel air coolers offer intelligent electric defrost, hot-gas bypass defrost, and water shower defrost systems. Heat is focused strictly within the finned core to eliminate ambient room temperature spikes during defrost cycles.
Equipped with high-efficiency, low-noise external rotor axial fans with IP55/IP65 ingress protection. Precision air guide cowls provide air throw distances exceeding 35 meters, ensuring deep cold penetration through densely stacked seafood pallet arrays.
Exposed marine environments and fish processing halls utilize aggressive chemical sanitation agents. All Kabel casings, drain pans, and brackets are available in electro-galvanized powder-coated finishes or marine-grade 304/316L stainless steel for 10+ years of rust-free longevity.
Seamlessly engineered to operate across eco-friendly HFC/HFO blends (R404A, R507A, R448A/R449A), ultra-low GWP Natural Refrigerants including CO2 (R744 transcritical/subcritical systems), and industrial Ammonia (R717) pump-circulation facilities.
Integrated electronic expansion valve (EEV) interfaces and multi-point temperature sensors enable real-time dynamic superheat calibration, optimizing compressor operation and lowering annual power consumption by up to 24%.
Tailored refrigeration solutions addressing every critical junction of the modern aquaculture and ocean-fishing supply chain.
When pelagic fish like Bluefin Tuna, Yellowfin, and Mahi-Mahi are caught, enzymatic decomposition begins immediately. Onboard flash-freezing rooms rely on Kabel high-pressure blast air coolers designed for extreme maritime pitch-and-roll conditions. The units deliver violent, uniform cold air velocities that lock in sashimi-grade freshness within 2 to 4 hours of harvest.
Shrimp and squid require rapid surface glaze solidification to prevent clump adhesion and maintain moisture balance. Kabel evaporators deployed in continuous spiral or fluidized IQF tunnels feature large fin spacing (up to 12mm) to support non-stop 18-hour production runs before requiring quick water-defrosting cycles.
Large-scale port distribution hubs store thousands of pallets of frozen cod, salmon fillets, and crab legs. Kabel high-efficiency industrial air coolers maintain rock-solid isothermal conditions throughout warehouse heights exceeding 20 meters, preventing top-tier pallet thermal degradation and sublimation weight loss.
For fresh, non-frozen oysters, lobsters, and whole wet-market fish, excessive airflow drying can destroy product quality. Kabel dual-discharge air coolers distribute gentle, low-velocity, high-humidity cold air currents that prevent ice melt, preserve gill red color, and extend fresh shelf life by 4 to 6 days.

As global decarbonization targets and strict seafood HACCP/FDA quality mandates converge, industrial seafood refrigeration is undergoing rapid technological transformation.
The phase-down of high-GWP refrigerants under the Kigali Amendment has accelerated the adoption of CO2 (R744) cascade systems and low-charge Ammonia (NH3) units in seafood hubs. Kabel air coolers are built with high-pressure stainless steel circuits rated up to 90 bar to support transcritical CO2 operations reliably.
Fixed-timer defrost schedules waste significant electrical energy and cause undesirable chamber temperature cycling. Kabel systems incorporate AI machine vision and differential pressure sensors that trigger defrost cycles only when frost density reaches critical thermal resistance, cutting defrost power costs by 40%.
By shifting from standard AC motors to variable-speed EC fans, Kabel units adapt their airflow delivery dynamically. During initial blast freezing pull-down, fans operate at 100% capacity; during steady-state holding, fan speed drops to 60%, drastically minimizing cold room power draw while preventing moisture loss.

Key thermodynamic and operational considerations when specifying Kabel air coolers for aquatic preservation projects.
Seafood dehydration occurs when high temperature differentials (ΔT) between the coil and room air draw moisture out of the product. Kabel evaporators are engineered with generous coil surface areas that operate at an optimized low ΔT (4K to 6K), sustaining relative humidity levels above 92% to prevent freezer burn and weight shrinkage.
For fresh, wet seafood blast freezing applications where humidity is extremely high, we recommend a progressive fin pitch of 10mm to 14mm on the air-inlet side and 8mm to 10mm on the air-outlet side. This prevents early frost bridging on outer coils, extending operating intervals between defrost cycles.
All copper tubes undergo automated expanding with tight mechanical bonding to hydrophilic or epoxy-coated aluminum fins. Outer sheet metal is treated with 120-micron electrostatic powder coating or constructed using SUS304/SUS316 stainless steel, passing rigorous 1,000+ hour neutral salt spray (NSS) testing.
Yes. Kabel units feature standardized connection manifolds suitable for direct expansion (DX), flooded barrel pump recirculation, or secondary chilled brine fluids. Multiple circuit distributor options ensure precise liquid distribution regardless of compressor rack brand.
