It is a technically advanced con-

 

trolled mechanical ventilation sys-

 

tem designed to meet the require-

 

ments of modern, tightly built and

 

highly insulated buildings. It pro-

 

vides a consistent supply of fresh

 

air while lowering heating costs

 

during the winter by transferring

 

heat from the exhaust air to the

 

fresh air stream. During the sum-

 

mer it also reduces the load on the

 

air conditioner by lowering the tem-

 

perature of the fresh outdoor air.

 

(For southern climates, where air

 

conditioning costs are the major

 

concern, it can be provided with an

 

enthalpy core, on special order, to

 

reduce the humidity of the fresh air

 

as well as lower the temperature.)

HRV 700SFD, HRV 700SDD specifications

The American Aldes HRV 700SFD and HRV 700SDD are advanced heat recovery ventilators designed to enhance indoor air quality while maintaining energy efficiency. These units are ideal for both residential and commercial applications, providing a balanced airflow that promotes a healthier living environment.

One of the main features of the HRV 700SFD and HRV 700SDD is their exceptional heat recovery capability. These ventilators can recover up to 80% of the heat from stale indoor air, transferring it to the incoming fresh air. This process significantly reduces heating and cooling costs, making the units highly economical and environmentally friendly.

These models are equipped with advanced energy-efficient ECM (Electronically Commutated Motor) fans, which provide quiet operation and optimal airflow. The ECM motors adjust their speed automatically according to demand, ensuring that the system operates at peak efficiency without compromising comfort.

The HRV 700SFD features a vertical configuration, making it suitable for tight spaces or applications where ceiling height is limited. On the other hand, the HRV 700SDD is designed with a horizontal configuration, making it an excellent choice for situations where horizontal space is a consideration. Both models allow for easy installation and maintenance, as their thoughtfully engineered design facilitates access to key components.

Furthermore, these heat recovery ventilators include a robust control system that allows for customizable operation. Users can set specific operating modes and schedules, ensuring that the ventilation aligns with their unique lifestyle needs while optimizing energy use. The models come with both wall-mounted and remote control options for added convenience.

The exchange core used in both the HRV 700SFD and HRV 700SDD is made from durable materials that resist moisture and mold growth, ensuring longevity and hygienic performance. Moreover, the units are backed by American Aldes’ commitment to quality, providing peace of mind to consumers.

In summary, the American Aldes HRV 700SFD and HRV 700SDD are outstanding choices for heat recovery ventilation. With their high heat recovery efficiency, advanced ECM motors, versatile configurations, and user-friendly controls, they stand out as practical solutions for achieving superior indoor air quality while reducing energy consumption.
