Rooftop Air Handler

Rooftop Air Handling Units (RTU) by EKG (Malaysia) SDN BHD

In the industrial and commercial developments of Kuala Lumpur and Selangor, roof-mounted cooling solutions are essential for maximizing internal floor space. EKG (Malaysia) SDN BHD specializes in the engineering and installation of Rooftop Air Handlers (RTUs), designed to withstand Malaysia’s harsh solar radiation and heavy tropical rainfall. Whether serving a large-scale factory, a retail mall, or a standalone commercial building, our rooftop units are built for durability and high-capacity performance.

As a specialized installation contractor, we ensure every rooftop unit meets MS 1525 standards and remains fully compliant with the energy mandates of EECA 2024.

Engineering for Environmental Resilience

Rooftop units face extreme environmental stressors that indoor units do not. EKG focuses on "hardened" specifications to ensure long-term reliability.

1. Weather-Proofed Construction

• Corrosion-Resistant Casings: We specify units with high-grade galvanized steel or aluminum cabinetry, finished with UV-resistant polyester powder coatings. For facilities in high-pollution or coastal areas, we utilize specialized anti-corrosive treatments for the cooling coils to prevent premature degradation.

• Water-Tight Integrity: Our rooftop installations feature double-sloped roofs and integrated rain hoods on all fresh air intakes. This prevents water ingress during heavy monsoon downpours, protecting the internal mechanical and electrical components.

2. Thermal Management & Energy Shielding

• High-Density Insulation: To combat solar heat gain, we utilize double-skin panels with high-density polyurethane (PU) foam. This ensures that the intense heat on the roof does not penetrate the AHU casing, maintaining the "coolth" of the processed air.

• Thermal Break Technology: We incorporate thermal break profiles to eliminate "cold bridging." This prevents external condensation on the unit, which would otherwise lead to roof rust and structural water damage.

Strategic Operational & Structural Benefits

EKG (Malaysia) SDN BHD ensures your rooftop HVAC system is an asset to both your building’s design and its operational budget:

• TNB Cost Mitigation (VFD Synergy):

  Rooftop units are equipped with Variable Frequency Drives (VFDs) that modulate fan speed based on real-time load. This precision control directly lowers monthly TNB electricity bills and supports your facility's compliance with EECA 2024 energy intensity targets.

• Total 3D BIM Coordination:

  Rooftop MEP environments are complex, involving duct penetrations, electrical trays, and structural plinths. We use 3D BIM modeling to ensure a "clash-free" installation, mapping out service clearances so that routine maintenance is safe and efficient.

• Space Reclamation:

  By moving the AHU to the roof, we free up valuable internal square footage that can be used for production lines, office space, or retail displays.

Why Choose EKG (Malaysia) SDN BHD?

• Technical Integrity: We analyze the structural load-bearing capacity of your roof before installation, ensuring the mounting plinths and vibration isolators are engineered for safety and quiet operation.

• Turnkey Safety Compliance: All units and insulation utilize BOMBA-compliant, fire-retardant (Class 0 / B1) materials, meeting international safety standards (EN 13501-1).

• Specialized Installation Expertise: As dedicated contractors, we handle the complex rigging, precision crane lifting, and weather-proof duct penetrations required for successful rooftop integration.
