Saving Energy & Improving your Air Quality

Our technology improves your HVAC system and cuts costs

Our Internet of Things (IoT) system of air filtration devices and proprietary management software lets you tailor how you manage your HVAC system in real-time.

It’s a win-win for real estate owners and occupiers – a pragmatic, agile approach to addressing HVAC system shortcomings that helps you – and everyone in your existing spaces – breathe more easily.

The problem with HVAC today:

Central HVAC

Mechanical ventilation (central HVAC system) is the largest energy consumption item in a typical office building

Physical parameters

Energy consumption is unnecessarily high due to the large volume of outside air that needs temperature and humidity conditioning when entering a building. Using traditional HVAC, this is very expensive and difficult to optimise

Traditional ventilation

Traditional ventilation simply seeks to dilute indoor air pollutants with outside air. This is energy intensive and often ineffective – according to the US EPA, Indoor air quality is on average 2-5x worse than outside air quality

Regulations

Regulations, for instance EPC ratings and Local Law 97, as well as Net Zero ambitions means that doing nothing is not an option – however incumbent solutions are too expensive and slow to implement

Our Solution solves each of these challenges, and we can prove it

We retrofit HVAC systems without the complexities of in-duct work, or the cost of rip and replace. Our engineering team analyses buildings for optimal ventilation, implements standalone filtration devices throughout and adjusts the central HVAC system accordingly, unlocking significant energy efficiencies. All is monitored and managed via our software platform, Rensair Cloud®

SDCV: Smart Demand Controlled Ventilation

Rensair delivers SDCV for organisations to transform their HVAC.

9x less energy consumed per m3 of air through a traditional HVAC system

Rensair Energy Consumption: 0.6 Watts per m3
Typical Ventilation System: 5.5 Watts per m3

Reducing outside air intake, substituting with air purification:

SDCV optimizes the ventilation mix in a building by part substituting the mechanical ventilation with a more cost-effective air purification.
The total air volume remains unchanged, but energy consumption and carbon emissions are substantially lowered.

IAQ – Improving your Indoor Air Quality

Rensair has delivered best in class technology for decades. Here’s how our experience shapes our patented, award-winning hardware:

1. ENTRY

Dirty air enters the top of the device from 360 degrees

2. PROCESSING

Driven by a powerful centrifugal fan, dirty air passes through pre-filters before being forced into the HEPA filter for purification

3. CLEANSING

Our combination of filters and a UVC lamp traps particles, pathogens and gases

4. EXIT

Clean air leaves the device at 360 degrees

Tried, tested, patented technology, certified globally

Our patented air flow design combines HEPA H13 filtration, UVC light and gas removal.

The efficacy of Rensair’s patented technology is documented by leading independent scientific laboratories, including Eurofins, Norconsult, Oslo University Hospital, and the Danish Technological Institute.

Our technology has been adopted by hospitals, doctors surgeries and dental practices, and care homes worldwide, including many NHS trusts in the UK.

Rensair meets all of the air purification standards recommended by the UK SAGE committee and US EPA, and ASHRAE, and was included in Newsweek’s list of Best Infection Prevention Products 2021.
