In the large-scale commercial infrastructures of Kuala Lumpur and Selangor, high-pressure ducting is the critical delivery system for centralized HVAC and specialized smoke extraction. Standard ducting often fails under the intense static loads of high-rise air distribution. EKG M&E Sdn Bhd provides High-Pressure Galvanized Iron (GI) Ducting, specifically engineered to maintain structural integrity and airtightness at pressures exceeding 1000 Pa, ensuring your facility's cooling plant operates with industrial-grade reliability.
High-pressure systems require specialized fabrication techniques to prevent duct "ballooning," excessive vibration, and catastrophic air leakage.
Standard thin-gauge metal will flex and "oil-can" under high pressure. We mitigate this through:
Heavy-Gauge GI (G90): We utilize thicker steel sheets (up to 1.2mm/18G) to provide the necessary tensile strength. The G90 zinc coating ($275\ g/m^2$) ensures the steel remains rust-free in Malaysia's 90% humidity.
Internal and External Bracing: For ducts with large cross-sections, we install internal tie-rods or external angle-iron reinforcements. This prevents the duct walls from bowing outward under peak static loads, maintaining a consistent aerodynamic profile.
As pressure increases, even microscopic gaps become major energy leaks.
TDF/TDC Mechanical Joints: We utilize roll-formed Transverse Duct Flanges with specialized corner bolts. This creates a high-torque mechanical bond that traditional slip-joints cannot match.
High-Performance Sealants: We apply fire-rated, high-pressure polymer sealants to all longitudinal seams and joint faces, achieving a Class C Airtightness rating, which is essential for high-velocity systems.
As an HVAC and M&E Specialist, EKG ensures that high-pressure ducting delivers measurable mechanical efficiency:
TNB Energy Savings (VFD Precision):
High-pressure systems consume massive amounts of fan energy. By ensuring the ducting is Airtight (Class C), we eliminate the "leakage tax." This allows your Variable Frequency Drive (VFD) to run fan motors at lower frequencies (Hz) while still satisfying the furthest VAV box. A reduction in fan load directly results in a significantly lower monthly TNB electricity bill.
BOMBA & Smoke Spill Readiness:
High-pressure ducting is the backbone of Smoke Spill and Staircase Pressurization systems. These ducts must handle extreme pressure surges during a fire emergency. Our systems meet UBBL and BOMBA requirements, ensuring toxic smoke is extracted effectively without duct failure.
EECA 2024 & GBI Compliance:
Optimizing high-pressure networks is a core strategy for meeting the Energy Efficiency and Conservation Act (EECA) 2024 and achieving Green Building Index (GBI) certification by lowering the Building Energy Index (BEI).
| Feature | Standard GI Ducting | EKG High-Pressure GI Ducting |
| Operating Pressure | Up to 500 Pa | 1000 Pa to 2500+ Pa |
| Material Gauge | 0.5mm – 0.8mm | 1.0mm – 1.2mm+ (Reinforced) |
| Jointing Type | Slip / Drive / S-Cleat | TDF / TDC / Companion Flange |
| Leakage Class | Class A / B | Class C (High Efficiency) |
| Durability | Prone to vibration | Rigid / Low-Resonance |
Duct Leakage Testing (DW/143): We don't just "claim" high pressure; we prove it. We perform certified pressure tests to ensure the system meets international airtightness standards before commissioning.
Total Air Balancing: Post-installation, we use Anemometer Audits to certify that high-velocity air is being distributed proportionally across all zones.
Strategic Selangor Support: Based in Kuala Lumpur, we provide turnkey high-pressure fabrication for data centers, hospitals, shopping malls, and Grade-A office towers throughout the region.
