Blanket Wrap Insulation Systems

Flexible, removable thermal insulation solutions for complex geometries and maintenance-intensive equipment

The Challenge

Nuclear plant components with irregular shapes, frequent maintenance requirements, and space constraints demand insulation solutions that combine flexibility with performance. Traditional rigid insulation often results in gaps, thermal bridges, and extended installation times. Equipment requiring regular inspection and maintenance needs insulation that can be quickly removed and reliably reinstalled without degradation.

Our Solution

Moeller Nuclear's blanket wrap insulation systems deliver exceptional thermal performance through engineered flexibility. Our custom-fabricated blankets conform precisely to complex geometries while maintaining consistent insulation values. Advanced fastening systems enable rapid removal and reinstallation, reducing maintenance windows and ensuring repeatable performance through multiple cycles.

Conformable Design

Multi-layer construction with flexible core materials adapts to valves, flanges, pumps, and irregular surfaces, eliminating gaps and ensuring complete thermal coverage.

Durable Construction

High-temperature fabrics and reinforced seaming withstand mechanical stress, thermal cycling, and environmental conditions while maintaining insulation integrity.

Quick Access System

Innovative closure mechanisms including stainless steel drawstrings, hook-and-loop fasteners, and snap systems enable tool-free removal in seconds.

Advanced Features

Integrated Accessories

Optional features include inspection ports, thermocouple pockets, lifting handles, and identification tags to enhance functionality and maintenance efficiency.

Environmental Protection

Weather-resistant outer layers protect against moisture, chemicals, and UV degradation. Optional metal mesh guards provide mechanical protection in high-traffic areas.

Custom Engineering

Each blanket is precisely engineered using 3D scanning and CAD modeling to ensure perfect fit. Multi-piece designs accommodate complex assemblies while maintaining thermal efficiency.

Primary Applications

Our blanket wrap systems are optimized for:

Performance Benefits

Energy Savings

Reduce heat loss by up to 95%, lowering energy costs and improving system efficiency. Typical payback period of 12-18 months through energy savings alone.

Safety Enhancement

Touch-safe surface temperatures protect personnel from burns. OSHA-compliant designs maintain surface temperatures below 140°F on high-temperature equipment.

Maintenance Efficiency

Remove and reinstall in minutes versus hours for conventional insulation. Reusable design eliminates material waste and procurement delays.

Quality Standards
