As rising health awareness drives the need for clean air across Southeast Asia, Thai air-management innovator FreshNergy has introduced an advanced Positive-Pressure Air Purification System against particulate pollution. Distinguished from other air purifiers, FreshNergy’s systems pump in filtered outdoor air to create a pressure barrier, like an invisible shield, preventing unfiltered air leakage through gaps and ensuring stable oxygen-rich air. The innovation has set a new benchmark for indoor air quality across both modern corporate offices and luxury residences. To sustain this round-the-clock protection, FreshNergy adopts Delta’s new Panel Mount Power Supply - PMT2 Series to provide durable, stable, and safe power for operation.
Power as Bedrock: Exceptional Efficiency for Air Purification
The PMT2 Series, including the PMT-24V50W2BA model adopted by FreshNergy, delivers the efficiency, reliability, and durability required for demanding 24/7 air purification applications. With energy efficiency of up to 89% and industrial-grade durability, the PMT2 Series helps minimize energy loss and thermal stress, extending component life while maintaining stable, high-performance operation over time. Its mean time between failures (MTBF) exceeds 700,000 hours based on the Telcordia SR-332 standard – more than twice that of competing products – providing a highly reliable power backbone that helps FreshNergy’s positive-pressure air purification systems operate continuously with greater stability and reduced maintenance needs.
The PMT2 Series also enables more compact and flexible product designs. With an ultra-slim 29 mm profile, 32% smaller than the previous generation, the power supply helps reduce the overall volume of air purifiers by up to 15%, freeing valuable internal space for more compact and streamlined product integration. Its wide 90 – 264 VAC input range supports deployment across different regions without requiring multiple power supply configurations, while the -30°C to 70°C operating temperature range and -40°C cold-start capability ensure reliable performance even under challenging environmental conditions. Together, these design advantages give FreshNergy greater flexibility in developing compact, reliable, and globally deployable air purification solutions.
Notably, the PMT2 Series complies with IEC/EN 60335-1 and Overvoltage Category III (OVC III) criteria to address the stringent demands of non-stop operation in applications such as residential and office spaces. Meeting the SEMI-F47 standard, the Series effectively withstands voltage sags from lightning strikes or high-power machinery startups, eliminating power fluctuation risks to offer a consistently high-efficiency output.
Market Expansion: Empowering A New Era of Air Purification Market in Southeast Asia
Looking ahead, the PMT2 Series will keep translating exceptional power stability into tangible market success as FreshNergy’s Positive-Pressure Air Purification Systems have been adopted by over 1.6 million households within premium residential projects in Thailand. With deployment increasing sharply by 87% between 2023 and mid-2026, FreshNergy aims to install 650,000 positive -pressure air purification systems by the end of 2026 in Southeast Asia. Building on this momentum, FreshNergy anticipates continuing its partnership with Delta to jointly create healthy, comfortable living spaces.
