Rooftop Revolution
Imbat Says: “There Is a Better Alternative to the AHU + Chiller / VRF Equation”
As one of the pioneers of the HVAC industry, Imbat aims to transform long-established system conventions by offering a simpler, more efficient alternative to the complex configurations traditionally used in centralized air conditioning systems.
This alternative will be showcased to visitors at the Sodex Istanbul Exhibition, taking place October 21–25 (Hall 4, Stand A02), where attendees will have the opportunity to explore the solution firsthand.

AHU + Chiller / VRF Configurations Create Efficiency Debates
Traditional Air Handling Unit (AHU) + Chiller or AHU + VRF combinations often lead to installation complexity on site due to the large number of separately operating components. These configurations typically result in high initial investment costs and challenging commissioning processes.
Each component requires its own infrastructure, automation, and energy management system, creating a significant burden in terms of both time and resources.
Rooftop systems present an integrated alternative to this conventional setup. By consolidating all air-conditioning functions into a single unit, they reduce the number of components, simplify installation, and streamline system management. With fewer elements on site, they achieve higher efficiency while enabling a more streamlined design and faster commissioning. Their centralized control structure also optimizes maintenance processes and reduces operational costs.
In this respect, rooftop systems represent not only a product choice but also a strategic simplification in project management.
At this point, it becomes crucial to see how these structural advantages translate into a real engineering solution in the field. The Perseus Rooftop series, developed by Imbat, stands out as a solution that technically integrates this approach while delivering tangible benefits in terms of energy efficiency and ease of application.
Perseus Rooftop Aligns with the Needs of Next-Generation Projects
Perseus Rooftop not only simplifies the integrated HVAC concept but also sets a new benchmark in long-term performance and sustainability.
The unit stands out with efficiency levels exceeding the latest EcoDesign+ criteria. Its double-skin casing features 50 mm thick A1-class stone wool panels and 70 kg/m³ density rock wool insulation, reducing heat losses, enhancing fire safety, and improving acoustic performance.
In addition to the traditional R410A refrigerant, Perseus Rooftop can also operate with R454B, which has 78% lower environmental impact, significantly reducing the carbon footprint while delivering high efficiency and environmentally responsible performance.
With an airflow capacity ranging from 3,850 to 55,200 m³/h and cooling capacity between 60 and 360 kW, Perseus Rooftop adapts to a wide range of project scales.
Replacing multiple pieces of rooftop equipment typically used in conventional systems, this compact structure shortens installation time, centralizes control systems, and eliminates on-site complexity. Optional features such as a HEPA filter module for improved indoor air quality and a thermodynamic heat recovery system capable of delivering up to 30% energy savings further enhance user comfort while reducing energy consumption.
With the Perseus Rooftop, Imbat is not only introducing a new product but also reshaping the way the industry thinks. By replacing fragmented, high-cost traditional system designs with simplified, integrated, and sustainable solutions, Imbat is leading this transformation in the HVAC sector.
The Perseus Rooftop series will be showcased to visitors at the Sodex Istanbul Exhibition, October 21–25 (Hall 4, Stand A02).
