DB16扬声器供潜在爆炸性的气体和尘埃环境中使用,此范围达 30 瓦的额定功率及适合使用在石油、 天然气和石油化工行业中找到离岸及岸在恶劣的环境条件下。单元提供双输出,容易安装,此外，25 瓦版本还提供了的输出具有较高环境认证温度 (+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.
