ERV90HC, HRV90HS, HRV90H, ERV90HCS specifications

The Broan HRV90H, ERV90HCS, HRV90HS, and ERV90HC are advanced energy recovery ventilators designed to optimize indoor air quality while efficiently managing energy consumption in residential and commercial spaces. These models exemplify the marriage of function, effectiveness, and technology to ensure that you have a constant supply of fresh air without sacrificing comfort.

One of the main features of these units is their energy recovery technology. The HRV models are designed to recover heat from the outgoing stale air and transfer it to incoming fresh air, while the ERV models go a step further by transferring both heat and moisture. This is especially beneficial in climates where maintaining humidity levels is crucial for comfort. By using these units, homeowners can enjoy fresh air without throwing away energy costs associated with heating or cooling.

The compact design of the Broan HRV and ERV systems allows for flexible installation in various settings. They can be easily integrated into existing HVAC systems or used in new constructions. Each model is equipped with user-friendly controls, featuring various operation modes to suit different needs, whether it's a high-demand situation or a standard ventilation requirement.

Another standout characteristic is their quiet operation. Engineered with sound-dampening materials, these units ensure that they run quietly, allowing you to enjoy a peaceful indoor environment. Additionally, their high-efficiency filters capture airborne particles, thus promoting a healthier living space by reducing allergens and other irritants.

In terms of energy efficiency, the Broan HRV and ERV units boast impressive performance ratings, which can help homeowners save significantly on energy bills over time. The technology used in these products meets industry standards and certifications, ensuring that they not only perform well but also adhere to environmental regulations.

With a commitment to quality and reliability, Broan offers these energy recovery ventilators as a smart choice for those looking to enhance indoor air quality while remaining energy-conscious. The HRV90H, ERV90HCS, HRV90HS, and ERV90HC are the perfect solutions for creating a more comfortable, healthy, and efficient living or working environment. Whether you are renovating an older home or planning a new build, these systems provide an innovative approach to modern ventilation needs.
