Keep Lobbies Comfortable with the Berner RevolvAir

Keep lobbies comfortable

The Revolvair, the Air Curtain System for Revolving Doors, supports the expectation that lobbies are comfortable and welcoming.

New Castle, Pa. – Berner International has now announced the RevolvairAir Curtain System for Revolving Doors.

The RevolvAir allows buildings to meet the expectation that occupants can comfortably socialize, work, and hang out in the lobby.

Comfortably socialize, work, and hang out in the lobby – with the Berner RevolvAir

The RevolvAir – takes the revolving door to a whole new level

While revolving doors significantly reduce a building’s energy consumption, they are not “airtight.” The revolving door acts as an air lock, bringing in people, but also outside temperatures and fumes, into the lobby. When outdoor temperatures are extreme – as they can be in Winter – the entrance of cold air & fumes is quite noticeable.  This ruins the ambiance of the space. Conversely – when it is extremely hot outside, the entrance of hot air & fumes is also noticeable. When outside temperatures affect indoor temperatures, the HVAC system runs to compensate. In climates with temperature extremes, adding the RevolvAir over the revolving door works to negate the airlock effect.  This keeps the lobby comfortable for those spending time in it.  It also reduces the building’s overall energy consumption.

Designed to fit with the aesthetic of the entrance

The Revolvair is specifically-sized to fit each revolving door’s diameter, configuration and brand. It creates a separating air barrier at the building’s conditioned interior by blocking unwanted exterior air trapped within the moving door sections. Therefore, lobby entrances are protected from outdoor air elements, fumes and odors infiltration from the moving sections, as well as through the revolving door assembly’s gaskets and seal gaps. The Revolvair offers plenums in either concealed or aesthetically exposed configurations.  These can also be installed within a bulkhead. Trim packages come standard in a white powder coating to blend in with the space. However, any hue from the RAL color chart is available as well as metal finishes, such as anodized aluminum or brushed stainless steel to aesthetically match the finishes of the revolving door.

Controlled by the Intelliswitch digital controller with the Option to operate from your phone

One of the Revolvair’s unique features is Berner’s patented Intelliswitch. This digital controller is designed exclusively for air curtain operation in commercial occupied spaces. The Intelliswitch can operate as a stand-alone air curtain controller or it can be interlocked with any building management system (BMS). The Intelliswitch has a time clock, time delay, built-in thermostat, 10-speed fan control and other integrated features.  This is so that end-users can customize their air curtain functions.

the Berner Air Curtain App

The new “Berner APP” wi-fi mobile application for smartphones can also monitor and program Intelliswitch functions. The air curtain can be activated by the revolving door manufacturer’s interlock, the BMS or motion sensors.

Berner Engineering ensures air stream is V,V,U Balanced

The 10-speed fan feature, facilitated by an energy-efficient 1/2-hp motor and direct-drive fan blower, is critical.  It allows for the proper air curtain performance and balance of volume, velocity and uniformity (VVU Balance). As there is no wind pressure / air pressure difference for the system to overcome, the flexibility of the Intelliswitch allows for lower motor speeds. This, in turn, allows the system to provide enough CFM at the proper velocity to reach the threshold, without overdoing it, so that the air screen forms.

Supplemental Heat Available

Electric, steam and hot water coils are available as heating options to improve the air comfort of employees and patrons near the revolving door.  Additional heat is also used to offset thermal losses within the door enclosure itself. Electric heating utilizes Berner’s patented Venturi Heater, the world’s most efficient electric heater for air curtains.

Other RevolvAir features are:

  • Factory assembled and tested, then shipped as easy-to-install, lightweight modular sections. These consist of the air curtain, transition plenum and discharge plenum
  • Utilizes many proven components, technologies and quality control practices used in Berner’s renowned Architectural Series
  • Factory-mounted UL-listed control panel
  • Proprietary, high efficiency Pro-V Nozzle design strategically discharges air to meet the floor at the threshold or “break” for a total air seal around the opening
  • Intelliswitch is RoHS compliant
  • Parts warranty is five years—ambient; two years—heated

The Berner RevolvAir is the first air curtain system for revolving doors designed and engineered by a U.S. manufacturer.
