In the tropical, high-humidity climate of Kuala Lumpur and Selangor, "sweating" or external condensation on mechanical equipment is a pervasive issue that leads to structural corrosion, mold growth, and water damage. EKG (Malaysia) SDN BHD specializes in the engineering and installation of Double-Skin Air Handling Units (AHUs). These units are specifically designed with an insulated sandwich-panel construction to eliminate the thermal bridging that causes condensation, ensuring a dry and sterile plant room environment.
As a specialized installation contractor, we focus on high-integrity casing standards that meet MS 1525 energy requirements and support the longevity of your HVAC investment.
A double-skin AHU utilizes two layers of metal (typically galvanized or stainless steel) with a high-density insulation core, creating a "thermal break" between the cold internal airstream and the warm, humid ambient air.
1. High-Density Insulation Core
Polyurethane (PU) Injection: We specify panels injected with high-density polyurethane foam. This material provides superior R-values (thermal resistance) compared to traditional fiberglass, ensuring that the external surface of the AHU remains at ambient temperature even when the internal coil is at 7 degrees Celsius.
Anti-Fungal Properties: The closed-cell structure of the PU foam prevents moisture absorption, ensuring the insulation does not become a breeding ground for bacteria or lose its thermal properties over time.
2. Thermal Break Profiles
Eliminating Cold Bridges: Standard AHU frames can act as "conductors" for cold air. EKG utilizes units with specialized thermal break profiles—non-metallic gaskets or composite spacers that decouple the inner skin from the outer skin. This prevents "sweating" at the joints and panel frames.
EKG (Malaysia) SDN BHD ensures your double-skin system supports both building health and operational efficiency:
Corrosion Prevention & Longevity:
By eliminating external condensation, we protect the AHU casing and the surrounding floor from rust and water-borne degradation. This is essential for maintaining the professional appearance and structural integrity of mechanical rooms in high-spec corporate offices and factories.
Indoor Air Quality (IAQ) & Hygiene:
The smooth internal skin of a double-skin unit is significantly easier to clean than exposed insulation. This prevents "fiber stripping" (where insulation particles enter the airstream) and ensures a sterile environment critical for medical centers, pharmaceutical labs, and food processing plants in KL.
Total 3D BIM Coordination:
Double-skin units have a slightly larger physical footprint due to panel thickness. We use 3D BIM modeling to ensure a "clash-free" installation, mapping out service clearances to ensure that filters and coils can be replaced without interfering with structural beams or fire protection pipes.
| Feature | Single-Skin / Standard AHU | EKG Double-Skin AHU |
| Condensation Risk | High (Sweating on Exterior) | Zero (Thermal Break Engineered) |
| Energy Loss | Significant Thermal Leakage | High Thermal Retention |
| Cleaning & Hygiene | Difficult / Fiber Shedding | Smooth Internal Skin / Sterile |
| Acoustic Dampening | Minimal | Excellent (Noise Absorption) |
| Durability | Prone to Surface Rust | High Corrosion Resistance |
| Compliance | Basic | MS 1525 & EECA 2024 Compliant |
Technical Integrity: We don't just install equipment; we engineer the installation. We analyze the ambient dew point of your plant room to ensure the panel thickness and insulation density are correctly specified for zero condensation.
TNB Energy Optimization: By preventing thermal leakage through the casing, our double-skin units ensure that 100% of the cooling capacity reaches the occupied space, supporting compliance with EECA 2024 and lowering monthly TNB electricity bills.
Turnkey Safety Compliance: All double-skin panels utilize BOMBA-compliant, fire-retardant (Class 0 / B1) materials, meeting international safety standards (EN 13501-1).
