Baffle electric defrosting
The ULT series represents the pinnacle of ultra-low temperature freezing technology, offering processors an unmatched solution for preserving premium products where quality and freshness are non-negotiable. This is extreme cooling performance, perfected.
With its combination of robust engineering and intelligent freezing technology, the ULT series delivers transformative results for high-value cryogenic freezing applications - setting new benchmarks for speed, efficiency, and product quality preservation in the most demanding ultra-low temperature environments.
Extreme Deep Chilling & Cell-Level Freshness Locking
The biological composition of premium catches demands a freezing process that respects their delicate cellular structure. Conventional freezing often results in large ice crystals that puncture cell walls, leading to moisture loss and a compromised texture upon thawing. This system is specifically calibrated to conquer these biological challenges, delivering a ruthless and rapid temperature drop.
Rapid Crystallization Zone Bypass: The system forcefully drives the internal temperature through the critical -1.5°C moisture crystallization zone in record time, preventing the formation of damaging macro-ice crystals.
Absolute Biological Suspension: By achieving a stable -60°C environment, all cellular activity and enzymatic degradation are instantly halted, locking in the peak state of the catch.
Visual and Textural Preservation: Effectively prevents lipid oxidation, ensuring the highly sought-after ultra-red flesh tone and firm, buttery texture remain entirely intact for the most demanding culinary markets.
Premium Market Readiness: Guarantees that the thawed product exhibits the exact sensory profile of a fresh catch, maximizing the financial yield of high-value marine proteins.
Industrial-Grade Evaporator & Core Refrigeration Craftsmanship
Operating consistently at -60°C requires more than just powerful compressors; it demands an evaporator core built to withstand immense thermal contraction and extreme environmental stress. Every component within this system has been selected for its proven resilience in the harshest industrial applications. The craftsmanship reflects a deep understanding of ultra-low temperature physics, ensuring that mechanical failures are virtually eliminated.
Extreme Cold Tolerance: The specialized fan motors, pure copper tubing, and heavy-duty electrical wiring are custom-engineered to remain highly flexible and fully operational in continuous -60°C conditions.
World-Class Compression Power: Driven by industry-leading screw and inverter compressors from renowned brands like Bitzer, Mycom, GEA Grasso, and Hitachi, delivering relentless and stable cooling capacity.
Robust Copper Circuitry: Utilizing thick-walled, high-purity copper tubes designed to handle high-pressure refrigerants without the risk of micro-fractures during rapid temperature fluctuations.
Fail-Safe Drainage Infrastructure: Equipped with specialized, cold-resistant drainage pipes that prevent ice blockages, ensuring seamless moisture removal during defrost cycles.
High-Pressure Airflow Organization & Uniform Freezing Technology
Efficiency in large-scale processing is entirely dependent on how effectively cold air is distributed across the product load. Uneven freezing leads to inconsistent batch quality and potential product spoilage. This system utilizes advanced aerodynamic principles to ensure that every single item, regardless of its position in the chamber, receives the exact same thermal treatment.
High-Velocity Penetration: Employs a high static pressure, forced-air circulation system that aggressively pushes sub-zero air deep into densely packed product racks.
Rapid Core Pull-Down: The intense airflow guarantees that the chilling effect quickly reaches the very center of thick catches, drastically reducing overall processing times.
Zero Temperature Dead Zones: Optional, highly configurable ceiling plenums meticulously guide the airflow, eliminating stagnant air pockets and ensuring a perfectly uniform thermal environment.
Unwavering Batch Consistency: By standardizing the freezing rate across the entire chamber, facility managers can guarantee identical quality metrics for every single piece of high-value protein processed.
System Redundancy Design & Asset Security Guarantee
When housing inventory worth millions, the margin for equipment failure is absolutely zero. A single mechanical fault in a conventional system can lead to catastrophic financial losses. We have engineered this freezing solution with a paramount focus on risk mitigation, incorporating sophisticated fail-safes that actively protect your highly valuable assets around the clock.

Frequently Asked Questions (FAQ)
Navigating the complexities of extreme thermal management requires precise information. Below are detailed technical insights addressing the most critical operational inquiries regarding our advanced freezing systems.
How does the cascade refrigeration system maintain stability at -60°C?
The cascade architecture utilizes two separate refrigeration circuits working in tandem. The high-stage circuit cools the condenser of the low-stage circuit, allowing the system to reach extreme sub-zero temperatures with minimal mechanical strain. This dual-stage approach prevents compressor overheating and ensures highly stable, continuous cooling capacity even under heavy product loads.
Can the ceiling plenum be customized for existing facility dimensions?
Yes, the high-velocity forced-air circulation system is highly adaptable. We engineer custom ceiling plenums tailored to the specific spatial dimensions and racking layouts of your facility. This ensures optimized aerodynamic flow, eliminating temperature dead zones and guaranteeing uniform core pull-down across all batches.
What maintenance is required for the electric heater defrosting system?
The intelligent electric defrost system is designed for incredibly low maintenance. Because it activates based on precise sensor feedback rather than arbitrary timers, it experiences significantly less wear. Routine visual inspections of the heating elements and periodic checks of the specialized cold-resistant drainage pipes are sufficient to maintain peak operational efficiency.
How does the dual redundant system handle a sudden mechanical fault?
In the event of a primary compressor or fan anomaly, the integrated control logic instantly detects the pressure or electrical variance. Within milliseconds, the system automatically routes the thermal load to the parallel standby circuit. This seamless transition ensures zero interruption in cooling, triggering an immediate diagnostic alert while fully protecting the stored inventory.
Are the PIR/PU insulation panels suitable for highly corrosive marine environments?
Absolutely. The 150mm thick, 42kg/m³ density polyurethane panels are clad in high-grade, corrosion-resistant materials. Combined with the SUS304 food-grade stainless steel interior, the entire structural envelope is highly impervious to saline air, aggressive cleaning agents, and the rigorous demands of deep-sea fishing vessel installations.
