ERV Core Suppliers — Sourcing Energy Recovery Ventilator Cores
An Energy Recovery Ventilator (ERV) core is the heart of any HRV/ERV unit, transferring sensible and often latent energy between supply and exhaust airstreams without mixing them. Sourcing the right core—and the right supplier—drives efficiency, indoor air quality, and total cost of ownership. This guide covers what to specify and where to find verified ERV core suppliers.
What Is an ERV Core
An ERV core is a stacked or wheel-shaped heat- and moisture-transfer element. In a plate core, supply and exhaust run in adjacent channels separated by thin walls; in a rotary core, a sorbent-coated wheel spins through both streams. Both recover energy; the rotary version also recovers humidity.
ERV Core Types
| Type | Recovery | Best use |
|---|---|---|
| Paper / cellulose plate | Sensible + some latent | Cost-sensitive residential/commercial ERV |
| Polymer / membrane plate | Sensible + latent, washable | IAQ-critical, humid climates |
| Aluminum plate | Sensible only | High-temperature, robust duty |
| Enthalpy (rotary) wheel | Sensible + latent | Large airflows, humidity control |

Key Specs to Define
- Effectiveness: sensible and (if needed) latent recovery at your design airflow.
- Pressure drop: lower drop reduces fan energy; balance against effectiveness.
- Frost control: required in cold climates; ask about bypass or preheat.
- Cleanability: washable polymer membranes suit contaminated or humid air.
- Dimensions: match your AHU cassette; custom sizes are common.
How to Evaluate ERV Core Suppliers
- Confirm material and membrane certifications for your market.
- Request a performance curve at your operating point, not just a nameplate number.
- Use our supplier qualification checklist and vetting guide.
- Validate with a sample and a third-party or in-house test.

Frequently Asked Questions
What is the difference between an ERV core and an HRV core?
An HRV core transfers heat only; an ERV core transfers heat and moisture. ERV suits humid or dry climates where humidity control matters.
Which ERV core material is best?
Polymer membranes offer washable latent recovery and good IAQ; paper is lower cost; aluminum is robust for sensible-only duty.
How long does an ERV core last?
With proper airflow and periodic cleaning, quality cores run 5–10 years; washable polymer types extend service life.
Can suppliers provide custom sizes?
Yes—most offer custom cassette dimensions and fin geometries; see OEM/ODM services.
