Our DNA
What sets us apart.
Uncompromising Hygiene
Every hygienic AHU is built to VDI 6022 Part 1, the gold standard for hospital, pharmaceutical, and food processing environments. Stainless steel internals, smooth flat surfaces, and sealed panel joints that survive the harshest sanitisation protocols.
Green Innovation
EC fans with permanent magnet motors deliver 20-30% energy savings at rated speed and up to 50% at part load, which is critical in Thailand's variable-occupancy, high-humidity climate. All motors are ErP 2015 compliant with a 5-year warranty.
End-to-End Execution
From load calculation and AHU selection through factory manufacturing, customs clearance, on-site installation, DDC commissioning, and BMS handover. EverCool manages the complete supply chain so you deal with one accountable partner.
Trusted by the Best
TECH FREE systems are installed in private hospitals, GMP pharmaceutical plants, luxury hotels (including The Londoner, London), data centres, and cleanrooms across Southeast Asia. The same rigour applied to international hospitality is applied to every Thai project.
