Combined hot & cold service systems
Dual Insulation Work
Dual-temperature insulation for piping and equipment that cycles between hot and cold service.
Overview
What we deliver
Some process services swing between hot and cold duty — start-up, shut-down, regeneration cycles, or intermittent operation. Zenerclad delivers dual insulation systems engineered to handle both regimes, with carefully selected materials, expansion provisions, and vapor barriers sized for the cold side. Used widely in chemical, refinery, and food processing applications.
Scope highlights
- Hot + cold cycling service
- Engineered for thermal swing
- Vapor barrier on cold side
- Expansion joints for thermal movement
- Anti-CUI primer systems
- Aluminum / stainless cladding
Our Process
From enquiry to handover.
- 01
Service Review
Temperature swing profile, cycle frequency, and material compatibility check.
- 02
Material Selection
Closed-cell systems with sufficient hot-side temperature rating.
- 03
Surface Prep
Anti-CUI primer with thermal-cycling resistance.
- 04
Layered Installation — Dual Insulation
Dual insulation is professionally installed in layers — PIR pipe section as the primary insulation, LRB (rockwool) mattress as the secondary layer, followed by SS / aluminium cladding for durable protection and superior thermal performance.
- 05
Vapor Barrier & Cladding
Vapor barrier installation, precision SS cladding, and thorough final QC inspection ensure moisture protection, thermal efficiency, durability, and quality compliance.
- 06
QC & Handover
Final quality inspection, documentation, and project handover.
