3. Efficient enthalpy recycling
The internal HTR polymer membrane boasts excellent transmission performance, with test results showing exceeding 8000 g/m².24h, enhancing enthalpy efficiency significantly.
4. Superior gas-tightness
Featuring an optimized frame design with HTR polymer membrane, the core maintains an exceptional airtightness of 99%.
5. Low resistance surface
The core's HTR polymer membrane construction has a smooth inner surface, significantly reducing wind resistance.
6. Prevents condensate build-up
Thanks to the HTR polymer membrane Our innovative High-Efficiency Heat Recovery Core, with its exceptional high moisture permeability, is masterfully designed to prevent condensation even in environments with significant temperature differences. This advanced feature dramatically enhances the total heat exchange efficiency of your equipment, effectively reducing the need for frost drainage and ensuring optimal operation.
7. Outstanding Longevity
The robust integration of the durable ABS frame and high-performance HTR polymer membrane
bestows remarkable aging resistance to the cores. This extraordinary property ensures that the cores enjoy an extended lifespan of up to 5 years, with performance degradation kept impressively below 10% throughout their life cycle. Such durability translates to sustainable and reliable energy solutions.
Leveraging the superior performance attributes of the HTR Energy Recovery Core, our Energy Recovery Ventilation System offers users a remarkable combination of energy efficiency and comfort. It delivers a consistently fresh and invigorating air experience that has made it the preferred choice across various applications, including educational institutions, large retail complexes, upscale residential areas, and eco-friendly low-energy constructions.
