Finland: Professional Heat Exchange Technology
Enchoy OY is one of the world's earliest companies engaged in heat exchange research. With its professional expertise and years of dedicated study, the company has maintained a global lead in heat exchange technology standards.
Its innovative technology enables simultaneous exchange of temperature and humidity. The unique vortex-type plate design, along with its high-density and low-thickness characteristics, not only enhances gas isolation and thermal conductivity but also significantly improves heat exchange efficiency. With an enthalpy efficiency of 78%, it far surpasses the industry average of 55%.
In winter, the total heat exchange core absorbs heat from the indoor exhaust air and preheats the incoming fresh air, reducing the loss of indoor heat during the cold season. In summer, the process is reversed, and the total heat exchange core effectively retains the cooling energy from indoor air during energy exchange between indoor and outdoor air. This function optimizes the ventilation capability of air conditioning systems and reduces the cooling load.


Coarse Filtration: Effectively prevents particles in the air from passing through gaps; efficiently filters dust, debris, hair, and other particulates from the air.
Silver Ion + Medium Efficiency + Activated Carbon] Composite Filter:
A multi-layer composite filter integrated into one unit. The silver ion filter effectively inhibits bacterial growth and blocks microorganisms and allergens. The activated carbon filter, made using high-quality coconut shell activation technology with a formaldehyde-locking formula, strongly decomposes chemical pollutants such as formaldehyde, benzene, and TVOCs, offering enhanced and long-lasting adsorption performance. The medium-efficiency filter removes microscopic particles as small as microns, and its special folded design reduces wind resistance, effectively extending the lifespan of the high-efficiency filter.
HEPA High-Efficiency Filter: The filter core utilizes H12-grade HEPA with electrostatic composite filter paper, automatically adsorbing and intercepting 0.3-micron particles, thereby extending its lifespan. It achieves a PM2.5 removal efficiency of up to 99.34%.
