MKT 150/110 air whistle, suitable for vessels with a LOA > 200m

Regulations Before and After COLREG 1972

Before “COLREG 1972” (International Regulations for Preventing Collisions at Sea), low-pitched tones were often used for smaller vessels. However, the principle of reserving low tones for large vessels was not strictly enforced. The IMO regulations now reserve very low tones exclusively for the largest ships. For middle-sized and smaller vessels, there are broader frequency options available.

Signal Preferences and Frequency Range

IMO regulations prioritize signals that maintain audibility even at a distance. Vessels over 200 meters (656 feet) should use whistles with frequencies of 130 Hz or lower. These frequencies ensure effective communication and compliance with maritime safety standards.

Installation Instructions for MKT 150/110

Mounting the MKT 150/110

Secure the MKT 150/110 whistle with four M12 bolts to an outrigger or similar construction. Ensure the structure is stable to prevent any operational issues.

Cleaning the Supply Pipe
Before connecting the supply pipe to the whistle, blow the pipe thoroughly clean. This step is crucial to avoid any functional troubles caused by debris or contaminants in the pipe.

Installing a Primary Filter
If the pipeline above deck exceeds 100 meters (328 feet), install a primary FILTER TP 15/2 at the base of the mast. This filter protects the whistle from water condensate and rust particles, ensuring reliable operation.

Maintaining the Filter
Regular maintenance is essential for ensuring optimal performance. To begin with, it is recommended to drain the filter approximately once a month. By doing so, you can effectively prevent blockages while also maintaining the integrity of the signaling system.

MTX 150/130 electrically driven piston whistle, suitable for vessels with a LOA >200m.

General Information

The ELECTRO–TYFON® MTX 150/130 is an electrically driven piston ship’s whistle. It features minimal moving parts, a “swinging piston,” a cylinder that requires no lubrication, and an oil-free gearbox.

Key Features

• Unsymmetrical Sound Distribution: The design ensures the sound is distributed unevenly for efficient signaling.
• Adaptability: It operates effectively in all temperatures without additional measures.
• Stability: The whistle remains unaffected by voltage and frequency fluctuations.
• Maintenance-Free: The whistle is oil-free, non-corrosive, and requires no maintenance.
• Easy Installation: Simplified installation process.
• Compliance: Fully complies with International Regulations IMO 1972.

All-Temperature Operation

The ELECTRO–TYFON® MTX 150/130 delivers high performance in both arctic and tropical climates. Its patented system, featuring a high-efficiency rectangular horn and a specially designed motor, automatically adjusts the motor speed to match the horn’s acoustic resonance, regardless of ambient temperature. This ensures the whistle remains unaffected by onboard voltage and frequency fluctuations.

Unsymmetrical Sound Distribution

IMO Regulations demand a high Sound Pressure Level for effective signaling, but the sound level at the vessel’s listening posts should not exceed 110 dBA. To solve this, the whistle is typically placed high above the deck. However, if the highest point is insufficient, doubling the distance between the listening post and the whistle can reduce noise by 6 dB.

General Information

To ensure safety, the TK80 contactor unit includes a thermal overload relay that protects the installation from excessive current. This relay has a set point of 13A, providing reliable protection during operation. By default, the relay operates with an automatic reset feature (A), which simplifies management for users. However, operators can change the relay function to a manual reset option (H). In this case, the user must reset the overprotection using the green pushbutton, adding an extra layer of control.
 

Additional Features

Moreover, the unit supplies heating voltage to the ELECTRO-TYFON®. This heating voltage automatically switches off during signaling, optimizing energy efficiency and enhancing safety. As a result, operators can count on the system for consistent performance and protection under various conditions. Overall, these features make the contactor unit a vital component in ensuring reliable and safe operation.
