KTV 75/400 Air whistle,  suitable for vessels with a LOA up to 20m.

General Information

The KTV 75/400 signaling apparatus is lightweight, durable, and powerful, making it ideal for (Inland) ships. The KT 75/400 can be used for various applications, including, industrial settings, military use, and heavy vehicles. It is made from high-impact, vibration-resistant plastic resin, with some parts reinforced by glass fiber for extra strength. The design is entirely maintenance-free, and the diaphragm never wears out, ensuring long-lasting reliability.
 

Mounting and Installation

The valve comes equipped with a filter and complete fittings for both plastic tubing on the outlet side and copper piping (O.D. 8mm or 0.3”) on the inlet side. For optimal performance, avoid outdoor placement unless protected by a cover. Additionally, the short connection between the valve and the signal apparatus should be made from flexible material, such as rubber hose or plastic tubing, for improved durability.
 
For distinct code signals, keep the pipeline between the whistle and the valve under 6 meters. If placed outdoors, always protect the valve with a cover to prevent exposure to harsh elements. Before connecting the signal apparatus or valve, thoroughly blow the pipe line clean using compressed air to avoid any blockages.

MLT 75/345 Air whistle, suitable for vessels up to LOA 20m. Approved for inland vessel.

Compact and Efficient Signaling Whistle

The TYFON® MLT 75/345 ND is designed for vessels up to 20 meters in length, meeting IMO requirements for signaling equipment. It achieves a sound pressure level of 120 dB within one 1/3 octave, ensuring compliance with international maritime standards. The system offers practical features tailored for effective and reliable performance on board.
 

Key Features for Optimal Performance

• Electrically driven compressor: Eliminates the need for pressurized air on board.
• Thermostatic heating: Ensures consistent operation even in colder conditions.
• Low power consumption: Designed to deliver high sound output with minimal energy usage.
• Easy installation: Simplifies the setup process, saving time and effort for ship crews.

Installation and Electrical Setup

For optimal sound distribution, mount the whistle as high and free of obstructions as possible. This positioning ensures all-around sound radiation, which is crucial for effective signaling. Additionally, the compressor is housed in a protective box with a built-in heating unit, ensuring reliable operation in all weather conditions.
 
When connecting the compressor, wire it to the power relay, which is controlled by a push-button switch. Be sure to check the polarity of the compressor during installation. For a 24 V system, use a cable section of at least 2.5 mm² and protect the circuit with a 16 A slow-blow fuse for safety and performance.
 
With its durable design, ease of installation, and energy efficiency, the TYFON® MLT 75/345 ND is an ideal choice for small vessels, offering robust performance while fully complying with IMO regulations.
