Manufacturer Custom ERV vs HRV unit
In the ever-evolving world of HVAC design, energy recovery has become an essential component of high-performance building systems.
Two of the most commonly implemented technologies—Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs)—offer valuable methods for improving indoor air quality while reducing energy consumption.
At ER Flow, we recognize the importance of selecting the right solution for your specific application, and we offer tailored, low-maintenance options that are engineered for seamless integration with existing infrastructure.

ERV vs HRV: Comparing Heat and Energy Recovery Solutions in HVAC Design
Understanding the Technologies
ERV (Energy Recovery Ventilation) systems are designed to transfer both sensible (heat) and latent (moisture) energy between incoming outdoor air and exhaust air streams. This is particularly beneficial in climates with high humidity or extreme temperature fluctuations. ERVs help maintain indoor humidity levels, reducing the load on HVAC equipment and improving occupant comfort.
HRV (Heat Recovery Ventilation) systems, on the other hand, recover only sensible heat. These systems are better suited for colder, drier climates where humidity control is not a major concern. By preconditioning the incoming air with the heat from the exhaust air, HRVs significantly reduce heating loads and improve energy efficiency.
While both ERV and HRV systems enhance ventilation efficiency, the choice between them depends largely on climate and building requirements. ERVs are generally recommended for mixed or humid climates where controlling moisture levels is as important as recovering heat. In contrast, HRVs are typically deployed in cold and dry environments where moisture recovery might lead to issues such as frost buildup or excess indoor humidity.
A key consideration in selecting an energy recovery solution is maintenance. Unlike traditional energy wheels, which require routine cleaning and bearing inspection, plate-type heat exchangers used in ER Flow’s ERV and HRV solutions are completely maintenance-free. With no moving parts, they offer long-term reliability, consistent performance, and reduced operational costs—an ideal choice for building owners and facility managers looking to minimize service interventions.
The ER Flow Advantage
What sets ER Flow apart is our ability to design and manufacture custom ERV and HRV sections that can be seamlessly integrated with existing HVAC systems. Whether you’re working on a new air handling unit or retrofitting an older one, our flexible design approach ensures that our solutions match your system’s footprint, airflow requirements, and performance targets.
This adaptability makes our products ideal for energy retrofit projects, where improving energy efficiency and indoor air quality is essential but complete system replacement is not feasible. With ER Flow’s custom energy recovery solutions, you can extend the life of your equipment, reduce energy costs, and enhance sustainability—all without compromising reliability or comfort.
