As a leading Korean manufacturer of premium fin tubes, we strive to deliver top-tier quality, fast and flexible service, competitive pricing, and complete customer satisfaction. Our commitment to excellence and continuous improvement is at the heart of everything we do.

Embedded finned tubing is engineered for superior thermal efficiency, particularly in high-temperature applications. Its design ensures optimal heat transfer performance through a robust metal-to-metal bond between the fin and the tube.
Each fin is mechanically embedded into a precisely machined helical groove on the tube’s outer surface. During the manufacturing process, specialized rollers displace the groove’s metal and press it tightly against the base of the fin. This creates a secure, continuous contact area that maximizes thermal conductivity and ensures long-term durability, even under extreme operating conditions.
This construction method eliminates the risk of fin loosening or separation, making it ideal for demanding heat exchanger systems in power generation, petrochemical, and industrial processing environments.

Our advanced Fuel-Saving Antifouling (AF) Paint, formulated with the innovative F-DR-SPC polymer, reduces hull friction resistance by 15%—the highest rate globally. This surpasses leading products from the UK, Japan, and Denmark, which offer only 4–12% reduction. For a 10,000 TEU container ship, this translates to an estimated annual fuel savings of approximately USD 6 million. Environmentally friendly, the paint contains no harmful substances like cuprous oxide (Cu2O), significantly reducing marine pollution. Its superior antifouling properties prevent marine organism buildup, cutting fossil fuel consumption and lowering greenhouse gas emissions.

The AHHOI – Infrared Water-in-Oil Sensor is a technical development of Martechnic® in the area of the in-line oil quality monitoring designed for accurate real-time assessment. Based on the IR principle, the sensor measures continuously the content of water in lubricants of different origin and can be employed for various application systems (diesel engines, gearboxes and hydraulic systems). In comparison to other existing in-line water monitoring systems, the infrared technology of the AHHOI Sensor provides a crucial advantage, namely it enables determination
of water in all three states: saturated, emulsified and free.

The AHHOI Sensor is installed according to the bypass method: thereby it can be integrated on-site and connected to the lubricating oil system of the engine with a pressure ranging from 1 to 10 bars. As the sensor should be operated at a constant pressure of 1 bar, the integrated valve of the device helps to constantly maintain the pressure at the same level. The AHHOI requires a pressure free outlet (atmospheric drain) and incorporates a flush through system for cleaning, while the in-built oil filter protects the measuring cell of the sensor system.

Before starting to measure the degree of water concentration, the sensor needs to get pre-calibrated for a particular oil grade in use. The content of water then can be continuously measured in molecular form up to 10000 ppm / 1.0 vol. %.

The system is housed in a A3 sized IP 54 steel box and requires 100 - 240 V and has both serial and analogue outlets (0 - 20 / 4 - 20 mA) available.

The corresponding software for data recording in the framework of trend analysis is provided by Martechnic®.
