– ERV System - Total Heat Exchanger

– Cost-saving energy exchanger
By replacing your ventilation fan with Hitachi's Energy Recovery Ventilation (Total Heat Exchanger), you can reduce your annual electricity consumption by up to 36%* compared to regular AC operation with just a ventilation fan. The heat recovery system brings the outdoor air to the required indoor temperature.

– ERV system with design flexibility
- We offer a total of 14 different types of heat exchanger units, ranging from compact units measuring just 220×962×735mm (200m3/hr) to a most extensive energy ventilation recovery unit measuring 1,730×1,700×850mm (5,000 m3/hr). These options allow a single heat recovery unit to cover a large area.
- Our ventilation units come equipped with a controller as standard, allowing for easy adjustment of the external static pressure

– An ERV unit that brings you comfort and well-being
- You can choose between three ERV system operating modes: free ventilation, automatic ventilation, and heat recovery, to maximize air renewal, save energy, and improve air conditioning performance.
- 2-way ventilation, which involves bringing in fresh air from outside and expelling dirty indoor air, is a central aspect of improving indoor air quality.
