ARHC 2027: ASEAN RHVAC & Cleanroom Industry Expo

A three-day trade show for air conditioning, refrigeration, ventilation and cleanroom equipment, run by Compass Exhibition with the Thailand Convention and Exhibition Bureau listed as a supporter. It is aimed at contractors, building engineers and buyers rather than the public: visitors register on the organiser's site, and admission terms were not published when we listed it (1 October 2026). Hours of 10:00 to 18:00 come from the evntxpo listing; the organiser's own page gives only the dates. IMPACT is in Muang Thong Thani, Nonthaburi, about 25 km north of central Bangkok.
