🌎 EVER HEAT: Core Heat Exchange Solutions for ERV & DOAS Systems

Modern Buildings Are “Recycling” Waste Heat to Improve Energy Efficiency

Energy Recovery Ventilators (ERVs) capture 70–80% of exhaust air heat and use it to pre-condition outdoor air—significantly boosting a building’s energy performance and operating efficiency.

With today’s strict energy codes, energy recovery is essential for meeting ASHRAE 90.1 and the IECC requirements.

🔍 How ERVs Work (Sensible + Latent Heat Recovery)

An ERV uses a rotating enthalpy wheel or a polymer energy core to exchange:

• Sensible heat (temperature)

• Latent heat (moisture)

In winter: exhaust heat is recovered to warm and humidify cold outdoor air.
In summer: hot, humid air is pre-cooled and dehumidified before entering the building.

🏭 Common Application Areas

• Industrial / Manufacturing Facilities

• Healthcare Buildings & Laboratories

• Data Centers

• High-Density Electronic Environments

• Commercial Offices

• Schools & Universities

• Multi-Family Residential

• Any high-ventilation, high-energy-load environment

🔄 ERV vs. DOAS: A Combined Solution for Efficiency & Air Quality

• ERV (Energy Recovery Ventilator): Transfers heat and moisture between exhaust and supply air, improving ventilation efficiency.

• DOAS (Dedicated Outdoor Air System): A complete system that heats, cools, and dehumidifies 100% outdoor air before supplying it indoors.

Together, they form the backbone of modern high-performance ventilation systems.

🌡️ EVER HEAT: The Critical Role of Finned Heat Exchangers in ERV / DOAS Systems

As a leading manufacturer of finned heat exchangers, EVER HEAT provides the core heat-exchange modules that enable ERV and DOAS systems to perform efficiently and reliably.

⭐ 1. Precision Air Treatment: Heating / Cooling / Deep Dehumidification

In a DOAS system, the air treatment process heavily depends on finned heat exchangers.
EVER HEAT offers:

• Cooling coils

• Heating coils

• Reheat coils

• Multi-circuit custom designs

These coils deliver higher SHR performance, deeper dehumidification, and more stable supply-air conditions.

⭐ 2. Works Together with the ERV Core to Improve Total System Efficiency

Since ERVs cannot fully condition the airstream, EVER HEAT coils provide:

• Additional energy reduction

• Precise temperature control

• Secondary dehumidification (summer)

• Auxiliary heating (winter)

• Improved COP / EER

This combined effect can boost system efficiency by 20–40%.

⭐ 3. Built for Demanding Environments & High-Performance Applications

EVER HEAT offers multiple materials and corrosion-resistant finishes for long-term reliability:

• Copper tube – aluminum fin coils

• Stainless steel coils

• Anti-corrosion fin coatings

• Hydrophilic and anti-condensation coatings

Ideal for hospitals, labs, industrial sites, and other high-humidity, high-corrosion, high-load environments.

⭐ 4. OEM / ODM Support for ERV, DOAS & HVAC Manufacturers

EVER HEAT specializes in providing OEM/ODM heat exchanger modules, including:

• Fully customized dimensions

• Multi-row, multi-circuit coil design
