Kahlenberg S-330-DVM-H

The Kahlenberg S-330-DVM-H marine air horn provides a fully IMO compliant and ABS certified sound signal for commercial vessels up to 75m (246ft) with a heater for extreme conditions, all in a very compact package with the same benefits of the purpose-designed Kahlenberg S-330 air horn.

The Kahlenberg S-330-DVM-H features a heated operating valve offering dual electric operation with a manual override to provide for redundancy, enhancing crew and vessel safety.

The S-300-DVM-H’s heater is watertight and thermostatically controlled. It operates on 24VDC and 120VAC or 230VAC.

The finish of the horn is TGIC sky white powdercoat and it can safely operate down to -4°C. The S-300-DVM can be mounted to vertical or horizontal surfaces.

The S-330-DVM-H is an extremely attractive proposition for vessels where weight and space saving is a consideration or where a compact IMO compliant back-up whistle to the vessel’s main sound signal is required.

As with all Kahlenberg sound signals the S-330 is built in quality materials – spun brass and cast bronze, with a special alloy diaphragm. Its seamless bell avoids corrosion trap issues.

Because of the choice of design and materials you can expect extremely long and reliable service.

An unheated version of the Kahlenberg S-330 air horn is available.
