Daihatsu Oil Mist Monitor DOMM
Daihatsu DOMM oil mist monitor for shipboard spaces, based on the class-approved MD-SX detector, detecting abnormal oil mist from seal failures or burst pipes to help prevent fires.
Description
The Daihatsu Oil Mist Monitor DOMM is a version of the class type-approved MD-SX oil mist detector adapted for area monitoring on board ships. Sensor units installed where oil mist may occur detect abnormal changes in concentration early, revealing seal deterioration or pipe rupture so that fires can be prevented.
