Kuala Lumpur | February 13, 2026 — EKG M&E Sdn Bhd continues to demonstrate its technical leadership in the MEP sector with the successful execution of multiple high-stakes HVAC restoration and installation projects. These images document our recent works involving advanced cryogenic pipe freezing, large-scale cooling coil replacement, and new unit deployment for our commercial and institutional clients.
Scope of Work: Cooling Coil Replacement, Butterfly Valve Installation, and Cryogenic Pipe Freezing
The existing HVAC infrastructure at this high-occupancy corporate site showed critical signs of mechanical and thermal failure:
Cooling Coil: Heavy fouling and significant fin degradation were identified, which severely reduced heat transfer and increased energy draw.
Seized Valves: Primary isolation valves were non-functional, preventing essential maintenance without a full system shutdown.
Operational Constraint: The client required a solution that ensured zero building-wide downtime during the repair process.
To meet these demanding requirements, EKG implemented a specialized engineering protocol:
Cryogenic Pipe Freezing: Our technicians utilized liquid nitrogen to create a localized "ice plug" within the pressurized pipeline. This allowed us to isolate the work area and replace the seized valves without draining the entire building’s chilled water system.
Butterfly Valve Installation: Once isolated, the old components were replaced with high-performance lug-style butterfly valves for precise flow control and future-proof maintenance.
Cooling Coil Replacement: The degraded, fouled coil was systematically removed and replaced with a high-efficiency unit, restoring the system's original thermal rejection capacity.
Scope of Work: Unit Deployment, Structural Mounting, and Precision Integration
As part of a facility expansion, new high-capacity cooling was required to ensure consistent comfort levels for a large-scale commercial site.
Secure Logistics: EKG managed the safe transport and on-site positioning of multiple high-efficiency Daikin units. Our team ensures all equipment is handled according to manufacturer standards to protect warranty integrity.
Precision Installation: Technicians utilized scaffolding for high-level mounting of indoor units and outdoor condensers. All refrigerant lines were integrated using high-grade Armaflex insulation to prevent energy loss and condensation issues.
Commissioning: Each unit was rigorously tested for proper "Head" pressure and drainage flow to ensure reliable operation under high thermal loads.
0% Operational Interruption: Our use of cryogenic pipe-freezing technology allowed the client to maintain full business operations throughout the maintenance period.
Increased Efficiency: The new cooling coils and AC units are estimated to deliver a 15-20% improvement in thermal performance.
Long-Term Reliability: By replacing seized valves and aged coils, we have significantly extended the operational life of the facility’s MEP infrastructure.
