ZAVE^® Removable Insulation for Marine Exhaust Systems

Problems and Causes

 A shipyard is experiencing heat radiation problems from ship exhaust pipes and exhaust systems due to lack of thermal insulation. This has resulted in high heat accumulation in work areas, creating unsuitable working conditions. The hot pipe surfaces pose injury risks to workers through direct contact, reducing worker efficiency. The heat also affects engine performance, increases fire risks in the engine room, accelerates equipment deterioration, and results in higher-than-normal maintenance costs.

Improvement Method

Newtech Insulation Co., Ltd. has proposed a solution using ZAVE^® removable thermal insulation, specifically designed for marine industries, with these key features:

• Designed to cover entire exhaust systems (exhaust pipes, turbo, exhaust manifold)
• Uses high-temperature resistant materials that are non-flammable and non-combustible
• Easy installation and removal system requiring no special tools
• Durable insulation with long service life
• Fire Classification A1 certified according to DIN EN 13501-1:2019-05 standard

Improvement Results

Benefits after installing ZAVE^® thermal insulation:

1. Safety Aspects

• Reduces fire risks in engine rooms
• Controls exhaust pipe surface temperatures to safe levels
• Prevents direct contact with hot surfaces

2. Efficiency Aspects

• Significantly reduces engine room temperature
• Improves heat dissipation efficiency
• Reduces load on ventilation systems

3. Maintenance Aspects

• Easy to remove for inspection and maintenance
• Reduces maintenance costs
• Durable with less frequent replacement needs

4. Cost-Effectiveness

• Long-term cost savings with extended service life
• Reduced frequency of insulation replacement

ZAVE^® removable thermal insulation is therefore an ideal solution for reducing heat on ship exhaust pipe surfaces, with features that address both safety concerns and engine efficiency enhancement, making it a worthwhile investment.
