    Industrial Oven Insulation Rehabilitation

    A critical curing oven was consuming excessive energy with ±10-15°F temperature deviations causing scrap. CleanCap's thermal imaging revealed collapsed ceramic fiber and thinned firebrick. Complete multilayer insulation rehabilitation transformed the failing asset.

    Executive Summary

    A leading automotive components manufacturer depended on a high-temperature industrial curing oven. The oven began consuming excessive energy and exhibited temperature variability, leading to increased operating costs and scrap rates. CleanCap's investigation revealed severe deterioration of the insulation system. A complete insulation rehabilitation was executed, resulting in a 25% reduction in energy consumption and restored temperature uniformity.

    Customer Background

    The customer produces high-precision automotive components requiring tightly controlled thermal curing cycles. Their primary curing oven is a critical asset directly linked to production throughput. Recent issues included elevated fuel use and temperature deviations of ±10-15°F.

    Project Background

    Earlier attempts to diagnose the problem focused on burners and controls, but symptoms persisted. CleanCap mobilized an engineering team to perform a full thermal system audit using advanced diagnostics and infrared imaging.

    The CLEAN Approach

    C

    Consult & Analyze

    • Thermal Imaging: Hot spots discovered across oven walls and roof panels.
    • Internal Inspection: Identified collapsed ceramic fiber blanket and thinned firebrick sections.
    • Heat-Loss Modeling: Found 30% increase in heat loss compared to baseline.
    • Root Cause: Systemic insulation failure, not mechanical or controls issues.
