Background

For flammable adhesive and hazardous environment, the customer needed a fluid system that meets both multi-component precise ratio and explosion-proof safety standards. Gluexpert delivered a certified Exd IIB T4 explosion-proof 8-component fluid ratio system.

Safety Challenges

• Flammable & explosive: both adhesive and atmosphere carry explosion risk;
• Multi-component: 8 materials need independent precise metering;
• Compliance: must pass explosion-proof certification before production.

Solution

The whole system is designed to Exd IIB T4 explosion-proof standard, with explosion-proof electrical parts and pumps, 8 independent metering channels under central control, ±2% ratio accuracy.

Solution Highlights

• Fully explosion-proof: certified;
• 8 components: modular expansion;
• Safety interlock: auto shutdown on fault;
• Stable metering: ±2% accuracy.

Results

• 3 years of continuous safe operation, zero accidents;
• Stable multi-component supply, securing high-risk production;
• Passed acceptance, compliant production.
