In the high-humidity climate of Kuala Lumpur and Selangor, sensible cooling is only one part of the equation. High-Efficiency Latent Heat Recovery targets the energy-intensive process of removing moisture from 33°C outdoor air. Under the Energy Efficiency and Conservation Act (EECA) 2024, managing this "humidity penalty" is a regulatory requirement for achieving a compliant Building Energy Index (BEI).
At EKG M&E Sdn Bhd, we implement advanced recovery technologies that "recycle" the dry, cool state of your exhaust air to pre-dehumidify incoming fresh air, reducing chiller latent loads by up to 30%.
Unlike standard heat exchangers, high-efficiency enthalpy membranes allow for the simultaneous transfer of temperature and water vapor.
The Mechanism: The exhaust air ($24$°C, $50$% RH) is separated from the hot outdoor air by a semi-permeable polymer membrane. Water vapor molecules migrate through the membrane from the humid intake to the dry exhaust stream.
The Efficiency: Modern 2026 membranes, such as those utilized in EKG optimized ERVs, achieve a Latent Recovery Efficiency (LRE) of 60% to 75%, significantly lowering the dew point of the fresh air before it reaches your cooling coils.
For industrial and high-occupancy commercial spaces in the Klang Valley, liquid desiccant systems represent the pinnacle of latent recovery.
Direct Contact Dehumidification: The system uses a concentrated salt solution (desiccant) to absorb moisture directly from the air. The exhaust air is then used to "regenerate" or dry the desiccant, creating a continuous, high-efficiency moisture loop.
Energy Impact: Liquid desiccant systems can eliminate the need for over-cooling air to its dew point (and the subsequent need for energy-heavy reheat), slashing monthly TNB electricity bills for high-ventilation facilities.
In 2026, latent recovery must be monitored and verified to satisfy Energy Commission (ST) audits.
Enthalpy-Based Setpoint Reset: We program your Building Management System (BMS) to modulate the ERV bypass based on real-time outdoor enthalpy rather than just dry-bulb temperature. If the outdoor air is cool but "heavy" with moisture, the latent recovery remains active.
Star Rating Optimization: High-efficiency latent recovery is a primary driver for securing a 4-Star or 5-Star Energy Intensity Label. Our systems provide the digital data logs required for mandatory annual energy intensity reporting.

Total 3D BIM Coordination: We model complex recovery paths in 3D to ensure "clash-free" installation of ERVs and desiccant modules in congested ceiling or plant room spaces.
Psychrometric Forensic Audit: We conduct site-specific air stream analysis to calculate your exact tonnage reduction and ROI before installation.
Turnkey Validation: Every project concludes with a full Testing, Adjusting, and Balancing (TAB) report, providing verified recovery effectiveness data for your official energy audit.
