Chilled Water & Cold Insulation Systems

Insulation is necessary to prevent condensation (sweating) on cold pipe surfaces, reduce thermal energy losses, maintain water temperature, and protect against corrosion under insulation (CUI). It ensures energy efficiency and long-term system durability.

Common materials include Nitrile rubber (elastomeric foam like Armaflex), closed-cell rubber insulation, Polyurethane (PU), Phenolic foam, and PIR. Material selection depends on temperature range, humidity, and fire safety requirements.

Thickness is calculated based on operating temperature, ambient temperature, relative humidity, pipe diameter, and desired surface temperature. We perform dew point analysis and heat gain calculations as per IS/ASHRAE guidelines to select the optimal thickness.

A vapour barrier is a material (membrane, foil tape, or coating) applied over the insulation to prevent moisture ingress. It is critical because moisture penetration leads to insulation failure, corrosion, and mold growth.

Cold insulation is required for all surfaces operating below ambient dew point, including chilled water piping, CHW valves & fittings, FCU/AHU drain lines, refrigerant suction lines, and cold process pipelines.

Yes, we provide comprehensive repair and retrofitting services including damaged insulation replacement, moisture ingress correction, joint resealing, valve re-insulation, and CUI rectification to restore system performance.

Yes, we offer customized AMCs including periodic inspection, joint resealing, vapour barrier verification, moisture monitoring, and preventive replacement planning to ensure long-term insulation integrity.

CUI is corrosion that occurs on the external surface of piping due to moisture trapped under the insulation. It is a major risk in cold systems if the vapour barrier fails, leading to pipe degradation and potential leaks.

Proper insulation minimizes heat gain into the cold fluid, reducing the cooling load on the chiller. It also reduces pump load by maintaining consistent fluid temperature. This leads to significant energy savings and lower operational costs.

Our service includes surface cleaning, insulation sleeve installation, adhesive bonding, joint sealing, vapour barrier application, cladding, and inspection. We ensure a seamless, gap-free installation with continuous vapour protection.
