TMG Fire Suppression System Introduction

1. Mine Vehicle Fire Risks

• Nearly 55% of mine fires start from vehicle fires, with hot surfaces and overheating causing over 50% of such fires .

• Emission reduction demands (TIER 4F, EPA 2013) raise fuel pressure and engine compartment temperature, increasing fire risks; mining operations are sensitive to unplanned downtime, and engine fires may cause disasters like vehicle damage and casualties .

2. TMG-SAFETY "矿隧安" Fire Suppression System

(1) Features

• Fully automatic control, heat-induction startup (non-electric, suitable for coal mines), easy installation/maintenance, and applicable to heavy-duty mining machinery .

(2) Specifications
