IAQ (Indoor Air Quality) solutions

Breathe easy with our range of air renewal and air quality solutions. With our range of upgrades for existing or newly-installed AC systems, air handlers and easy to use ventilation options, you’ll find a solution to suit the needs of almost any business or commercial space.

Boost Wellbeing with Fresh Air

Today, the average person spends more than 75% of their day indoors; at home, at work, in the gym, shopping or socializing. Many of these environments are effectively sealed and fresh air isn’t easily available.

Without proper ventilation, CO2 levels rise, pollutants circulate and potentially harmful bacteria build-up, impacting on the wellbeing, comfort and productivity of occupants.

Make these spaces as healthy and comfortable as possible by providing fresh air with our premium ventilation systems for commercial buildings.

Our line-up fulfils the ventilation requirements of the desired space by drawing in clean air from the outside and replenishing indoor spaces. It features solutions that suit every type of building; You can use the ventilation technology alone or it can be incorporated into an Hitachi indoor unit via the fresh-air port*. Thanks to accessories like this, you can optimize the design of your system to meet your needs.

We provide heat treatment options that deliver fresh air at the temperature you want, and features like Free Cooling mode* that help achieve significant energy savings. We offer accessories that can further improve indoor air quality and operational efficiency like the optional C02 sensor*, which activates the equipment only when necessary. This lowers energy consumption and generates better savings, which is particularly beneficial for larger installations.

Hitachi ventilation solutions can be combined with filters to work in harmony with your air conditioning units to contribute to an even healthier environment.

Our solutions put the health and comfort of our customers at the forefront, improving the safety of indoor environments to deliver the optimal experience, whatever the weather.

Ventilation solutions that help to cut energy bills by up to 36%

Hitachi’s range of 1-way and 2-way ventilation solutions are compatible with VRF and commercial split systems(1). The All Fresh Air unit is a 1-way solution which brings fresh air into outdoor spaces pre-treating it using the refrigerant loop, while a 2-way energy recovery ventilation (ERV) solution is provided by Total Heat Exchanger which recovers energy from exhaust air to bring fresh air closer to the indoor temperature, thereby reducing loading on the AC system and lowering energy consumption by up to 36% compared with a simple ventilation fan (2).
