DB16揚聲器供潛在爆炸性的氣體和塵埃環(huán)境中使用,此范圍達 30 瓦的額定功率及適合使用在石油、 天然氣和石油化工行業(yè)中找到離岸及岸在惡劣的環(huán)境條件下。單元提供雙輸出,容易安裝,此外，25 瓦版本還提供了*的輸出具有較高環(huán)境認證溫度 (+65°C).
This range of loudspeakers, intended for use in potentially explosive gas and dust atmospheres, has a power rating of up to 30 Watts and is suitable for use in the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries.
With an integral increased safety chamber, for termination, this unit offers both high output and easy installation.
In addition, the 25 Watt version still offers superior output with a higher ambient certified temperature (+65°C).
The flamepaths, flare and body, are manufactured from a UV stable glass reinforced polyester. Stainless steel screws and mounting stirrup are incorporated to ensure a corrosion-free product.
