Freezing Systems by Havmek

Engineered for Efficiency, Designed for Consistency

Protect what you catch and preserve what you deliver.
Each Havmek freezing system is engineered for uniform core temperature, stable product handling, and long-term performance while keeping energy use and operational variability under control.

Built for Your Process
At Havmek, we engineer freezing systems that are configured to match your product mix, throughput targets, and plant layout. This tailored approach eliminates the need for expensive line adjustments that are often required with standard imported equipment.

Optimized airflow, supported by our in house impeller design, improves heat transfer efficiency and delivers faster, more uniform freezing with reduced power consumption.
IQF Spiral Freezer
What is IQF Spiral freezer?
IQF (Individually Quick Frozen) is a process where each piece of seafood is frozen separately to prevent clumping and maintain natural texture, color, and freshness. In a spiral system, controlled airflow ensures every piece receives the same cooling and dwell time, resulting in consistent core temperature across all pieces.
Technical Features
Refrigerant Flexibility

Supports CO₂ (R744), Ammonia (R717), Ice Water, and Brine systems. Optional CO₂–NH₃ Cascade System, co-engineered with NTNU, for deep freezing performance with reduced refrigerant charge.

Optimized Airflow

Draw through and blow through airflow options, with double impingement or horizontal airflow configurations. Indigenous aerofoil impeller design ensures uniform air velocity and rapid, even core cooling.

Direct Drum Drive

Low tension direct belt to drum engagement eliminates slippage, even under heavy loading. SS316L drum and reinforced frame ensure long-term stability and low mechanical wear.

Belt stability

Designed to handle heavier product weights without belt drift. Precision belt tracking maintains alignment and consistent product spacing.

Dynamic Product Guiding

Maintains product containment on the belt and prevents edge spillage during freezing.

Full CIP and Hygiene design

Fully CIP (Clean In Place) enabled with multiple stage wash zones for alkaline, rinse, and sanitise cycles. The integrated Hot Gas Defrost function minimises downtime during cleaning and product changeovers. Constructed entirely in SS304/316L with food grade welds and an open frame structure for total washdown access.

Integrated Smart Control

Equipped with PLC and HMI based automation for real time control of temperature, dwell time, and belt speed. The integrated IoT data logging platform allows remote diagnostics and performance tracking, ensuring consistent operational control.

Thermal and Energy Optimisations

High efficiency IE4 motors and variable-frequency drives (VFDs) achieve up to 20% lower specific energy consumption than conventional spiral systems. The insulated enclosure with Dow-grade panels (λ ≤ 0.022 W/m·K) prevents energy loss and condensation buildup.

Food Grade Compliance

IP67 stainless steel electrical cabinet for safe operation in cold, humid environments. System design compliant with ISO and HACCP hygiene standards.

FAQs
1. What refrigerants can Havmek IQF Freezers operate on?

Havmek supports multiple refrigerant choices including CO2, ammonia, ice water, and brine systems. Customers can choose the option that fits their energy goals, plant conditions, and sustainability requirements.

2. What is the CO2–NH3 Cascade Freezing System?

The CO2–NH3 cascade system uses both refrigerants in a dual-circuit setup to achieve deep freezing. This design is engineered for temperature stability and is developed in collaboration with the Norwegian University of Science and Technology.

3. How does Havmek maintain hygiene inside IQF freezers?

Havmek integrates multi-level Clean In Place systems, stainless steel construction, and hot gas defrost features. These allow thorough cleaning and reduce downtime during hygiene cycles.

4. How long does it take from placing an order to receiving a Havmek machine?

The overall timeline depends on the level of customization, site requirements, and project depth. Once the specifications are confirmed, our engineering team begins design and fabrication, followed by detailed testing and final commissioning. For clarity on your specific project, our expert consultant will guide you through an accurate schedule.

5. What are the initial steps to order from Havmek?

You can begin by contacting our team or writing to us at info@havmek.com and sharing your process requirements, layout details, and production goals. Once we understand your needs, we start the design and modeling process and outline the next steps for your project.

6. What can customers expect in terms of project communication?

Customers receive structured progress updates at regular intervals, including biweekly and monthly reports with photos, design checkpoints, and milestone summaries. This ensures full visibility throughout design, fabrication, and installation.

7. Can Havmek machines be upgraded or expanded in the future for compatibility and capacity increase?

Yes. During the early requirement discussions, Havmek factors in possible future needs such as capacity growth, product changes, or line expansion. This allows the system to support long-term scalability and remain compatible with future upgrades.

8. What does Havmek do?
