ASEAN long-haul operators in Thailand, Vietnam, Indonesia, Malaysia and the Philippines run trucks in 28–38°C ambient with 80–95% humidity year-round. Drivers resting at border crossings, ports and roadhouses face uncomfortable sleeper conditions and rising fuel costs. Vethy rooftop parking AC — 12V or 24V — provides engine-off cabin cooling with strong dehumidification performance tuned for tropical climates.

ASEAN long-haul corridors and rest-stop infrastructure

Trans-ASEAN corridors (Bangkok–Phnom Penh–Ho Chi Minh, Singapore–Kuala Lumpur–Bangkok, Jakarta–Surabaya, Manila–Davao) lack shore-power infrastructure at most rest stops. Drivers idle engines 6–10 hours per shift to power OEM HVAC, burning USD 600–1,200/year/truck in diesel.

Tropical humidity and dehumidification performance

Vethy units run an oversized evaporator coil that handles latent (humidity) load alongside sensible (temperature) cooling. Net result: cabin humidity drops from 85% RH ambient to 55–60% RH within 30 minutes, even at 32°C ambient — a major comfort upgrade vs OEM idle AC.

Sizing for Hino, Isuzu, FAW, Sinotruk and Mitsubishi Fuso

ZH 1000 (12V) suits Hino 500-series, Isuzu Giga, Fuso Fighter sleeper cabs up to 8 m³. VS02 PRO (24V) suits FAW Jiefang JH6, Sinotruk T7H and premium Isuzu sleepers up to 12 m³. Recommended battery bank: 200 Ah 12V or 150 Ah 24V LiFePO4.

Distribution and after-sales in ASEAN

Vethy partners with authorised distributors in Bangkok, Ho Chi Minh, Jakarta, Kuala Lumpur and Manila with stocked spares, local-language service documentation (Thai/Vietnamese/Bahasa/Tagalog) and on-site commissioning for fleets over 30 units.
