Adopts 3D three-direction counterflow heat exchange channel and nanoporous moisture-permeable membrane material, ultra-high heat recovery efficiency up to 95%. Antiviral & antibacterial, washable reusable core, widely matched with ceiling-mounted and wall-mounted ERV fresh air systems for villas, apartments, offices, schools and hotels. OEM custom total height size available.

· Core Structure Composition: ① ABS Outer Cover ② Nanoporous Moisture-permeable Membrane ③ ABS Support Frame ④ SUS Stainless Steel Outer Protective Shell

MENRED counterflow heat exchanger core is a high-efficiency energy recovery element specially developed for ERV energy recovery fresh air ventilators. Breaking the traditional single-plane cross heat exchange mode, it adopts innovative 3D three-direction cross counterflow channel structure. Supply air and exhaust air conduct full counterflow heat exchange from three directions, greatly expanding the heat transfer contact area and extending heat exchange duration, pushing the overall heat recovery efficiency up to 95%.

The heat exchange medium adopts high-performance nanoporous moisture-permeable membrane material, with excellent thermal conductivity, air tightness, oxidation resistance and mildew-proof performance. The membrane realizes enthalpy exchange of temperature and humidity, simultaneously recovering sensible heat and latent heat, balancing indoor humidity in summer and winter without extra humidifier/dehumidifier equipment. The material passes authoritative tests to reach 99% antiviral and 99% antibacterial rate, effectively inhibiting bacteria, mold and virus propagation inside the fresh air pipeline, improving indoor air health.

Different from disposable non-woven heat exchange cores on the market, this counterflow core is fully washable and reusable. Users can take out the core and rinse it with clean water regularly without purchasing replacement cores, reducing long-term maintenance cost of ERV equipment. The integrated ABS frame and SUS stainless steel outer cover provide strong structural rigidity, no internal air leakage, stable airtight performance under long-term wind pressure operation.

A complete range of counterflow specifications covers small household single-room ERV to large commercial multi-airflow HRV units, with multiple height and thickness options to match different ventilation equipment sizes. Custom OEM service is supported: customers can customize the total height of the core according to their own ventilator shell size. The product has wide working temperature adaptability with frost-resistant and moisture-resistant characteristics, stable heat exchange performance under low-temperature northern winter and high-humidity southern coastal climates.

All counterflow heat exchanger cores pass CNAS laboratory certification, and meet CE & RoHS environmental safety standards. Stable monthly mass production capacity supports customized size, private brand logo and neutral export packaging, serving global fresh air ventilator manufacturers, HVAC engineering contractors and fresh air system distributors.
