In the 2026 healthcare landscape, HTM 03-01 (Health Technical Memorandum) remains the gold standard for specialized ventilation in healthcare premises. While originating in the UK, its principles are widely adopted in Malaysia for private healthcare facilities seeking international accreditation and alignment with MOH (Ministry of Health) clinical safety standards.
At EKG (Malaysia) SDN BHD, we engineer AHUs that strictly adhere to HTM 03-01 design philosophies—ensuring that every component is accessible, cleanable, and aerodynamically optimized for EECA 2024 energy compliance.
HTM 03-01 places extreme emphasis on preventing the AHU from becoming a source of contamination through design and accessibility.
Internal Accessibility: All sections of the AHU (coils, fans, filters) must be easily accessible for inspection and cleaning. We engineer our units with full-height access doors on the service side, equipped with large, pressure-rated viewing ports and internal LED lighting.
Component Withdrawal: To comply with HTM 03-01 Part A, our heating and cooling coils are designed for easy withdrawal on slide-out tracks. This ensures that the deep cleaning required for Infection Control can be performed without dismantling the ductwork.
Anti-Corrosive Interior: We utilize SUS 304/316 Stainless Steel for the internal lining and all wet sections (drain pans and coil frames). This ensures the unit can withstand the aggressive biocides used during statutory clinical sanitization.
HTM 03-01 is particularly strict about stagnant water, which is the primary cause of Legionella and mold proliferation.
Open-Side Drainage: We utilize "Side-Withdrawal" drain pans that can be pulled out for inspection while the unit is running. These pans are multi-sloped to ensure a "Dry-Pan" condition within seconds of the unit being powered down.
P-Trap Design: Our systems utilize clear, medical-grade P-traps with a "Break-Tank" air gap. This prevents the back-siphoning of foul air from the drainage system into the sterile air stream.
The filtration sequence in an HTM 03-01 compliant unit is designed to protect both the building occupants and the internal components of the AHU.
Primary (G4) & Secondary (F7/F9) Stages: These protect the cooling coils from fouling, ensuring the unit maintains its Specific Fan Power (SFP) rating of < 1.1 $kW/m^3/s$ over its lifecycle.
Terminal HEPA (H13/H14): For high-risk areas like Operating Theaters, HEPA filters are placed as the final stage. HTM 03-01 mandates that these filters are tested "in-situ" using DOP/PAO ports, which are built into every EKG clinical unit.
UV-C Germicidal Integration: We integrate 254nm UVGI modules to continuously sanitize the coil surfaces, preventing the "bio-film" buildup that causes energy drift and odor.

HTM 03-01 units are traditionally large to ensure low internal air velocities. This aligns perfectly with the energy goals of 2026.
Low Face Velocity: By sizing the units for a face velocity of < 2.0 m/s, we reduce the static pressure drop across the coils. This allows our IE5 EC Fan Arrays to run at lower RPMs, slashing the Building Energy Intensity (BEI).
Airtightness (L1 Class): To ensure that every watt of "coolth" reaches the patient, our units are certified to L1 leakage standards. This prevents the "parasitic" loss of conditioned air into the plant room, a critical factor for statutory energy audits.
Technical Integrity: We provide the Validation Documentation (IQ/OQ) and SFP Performance Reports required for clinical accreditation and energy audits.
Precision BIM Coordination: We model the "Maintenance Envelopes" in 3D to ensure that the AHU rooms provide the clearance required for HTM 03-01 compliance.
BOMBA-Compliant Safety: All materials, including non-shredding insulation and clinical gaskets, are fire-rated (Class 0 or B1).
