Systemair Topvex FR

Topvex FR is a range of energy recovery ventilators with a low overall height and double rotating heat exchangers. The units are specially designed for maximum energy transfer at the lowest operating costs. This series of efficient ventilation units are designed for offices, shops, schools, daycare centers, or similar premises. The units are designed for high efficiency with very low energy use. Drain pans are not required, making the unit very flexible to install.


  • Low overall height: The unique design with double rotating heat exchangers makes it possible to produce the units with a low overall height. Using the enclosed suspension device, the unit can be installed in a false ceiling. To further simplify the use when mounted in a false ceiling, the hinges can be split, and the panels opened like doors.
  • EC fan motors: Unlike motors with frequency converters, EC motors ensure excellent efficiency even at low speeds. This contributes to low operating costs. EC motors are also very quiet when running at high and low speeds.
  • Pre-heater: The pre-heater enables the system to perform in extremely cold climates to preserve performance and ensure a continuous supply of air. It does this by warming the outdoor air before it enters the energy recovery wheel. The preheater is designed to keep the temperature above the frost threshold while remaining within the temperature range of the system.

Hotel Ella

Under new ownership, the historic building known as Mansion at Judges’ Hill recently transformed into Hotel Ella. The building, located near the University of Texas campus in Austin, went through a multi-million dollar renovation into a boutique hotel that is named after the building’s original owner, Ella Wooten. DXS was named basis of design for the project, retrofitting the common areas with 10 tons of Daikin heat recovery. The ductless units that Daikin offers integrated nicely with the existing architecture of the historic building. As a bonus, the increased energy efficiency and use of VRF qualified the owner for Austin Energy rebates.
