Today’s HVAC systems are expected to meet increasingly stringent requirements in terms of energy efficiency, sustainability and ease of installation. Among the most advanced solutions available on the market, OPTIMA ROOFTOP packaged rooftop air handling units stand out thanks to their compact design, intelligent controls featuring the MainBrain management platform and ClimaVisa visualization system, as well as their ability to significantly reduce operating costs.
OPTIMA ROOFTOP – A New Standard in Rooftop Air Handling
OPTIMA ROOFTOP is a packaged rooftop air handling unit that integrates cooling, heating and heat recovery ventilation within a single system. Designed as a monoblock unit, all functional components are housed inside one weatherproof enclosure, simplifying both installation and maintenance.
The unit is installed directly above the roof opening on a dedicated steel roof curb. The supporting frame is equipped with integrated lifting lugs, ensuring safe transportation and facilitating installation.
Advantages of OPTIMA ROOFTOP Units
At the core of the system is a reversible heat pump combined with a rotary heat recovery wheel. The components of the OPTIMA ROOFTOP air handling unit have been carefully engineered to enable operation with 100% outdoor air, while fully complying with the requirements of the Ecodesign Directive.
The compact monoblock construction minimizes installation time and eliminates the need for complex on-site assembly or extensive building works. Multiple configuration options allow the unit to be tailored to the specific requirements of each project, including the integration of supplementary heating sources such as hot water, electric or gas heating coils.
Energy-Efficient Technologies
OPTIMA ROOFTOP incorporates a range of advanced technologies designed to maximize seasonal energy efficiency.
Inverter Compressors
Variable-speed inverter compressors precisely adjust cooling and heating capacity to match the building’s actual demand, reducing energy consumption and improving operating efficiency.
Heat and Moisture Recovery
The rotary heat exchanger recovers both sensible and latent energy from the exhaust air stream, significantly reducing heating and cooling loads while improving overall system efficiency.
Integrated Refrigeration Circuit with Optimized Control Algorithms
The refrigeration system is managed by advanced control algorithms that ensure reliable and stable defrosting of the heat pump heat exchanger, maintaining high performance even under demanding outdoor conditions.
Economizer Damper System
The integrated economizer automatically optimizes the outdoor air intake using CO₂ concentration measurement and room temperature sensing, delivering only the required amount of fresh air while minimizing energy consumption.
Free Cooling Mode
When outdoor conditions permit, the unit utilizes cool ambient air for free cooling, substantially reducing compressor operating time and lowering energy costs.
Thermostatic Operating Mode
During periods of low building occupancy, such as nighttime operation, the thermostatic mode maintains the required indoor temperature while minimizing energy consumption.
Intelligent Control System
An advanced automatic control system continuously optimizes energy use according to outdoor weather conditions and building demand.
Centralized management of multiple air handling units is provided by the MainBrain control platform, while ClimaVisa offers intuitive remote visualization, system monitoring, operating data and energy consumption analysis.
Easy Installation and Maintenance
Roof-mounted installation eliminates the need for outdoor condensing units on building façades or additional mechanical plant rooms, maximizing usable indoor space.
Service access to all critical components has been designed to ensure quick inspections and simplified maintenance procedures, reducing service time and minimizing downtime.
Typical Applications
OPTIMA ROOFTOP air handling units are designed for buildings requiring efficient heating, cooling and heat recovery ventilation within a single integrated system.
Typical applications include:
- manufacturing facilities,
- warehouses and logistics centres,
- sports halls and sports facilities,
- retail stores and shopping centres,
- large commercial buildings,
- industrial facilities.
Summary
OPTIMA ROOFTOP represents a modern, high-performance and energy-efficient solution for commercial and industrial HVAC applications.
Its compact monoblock construction, intelligent control systems, integrated reversible heat pump and state-of-the-art energy-saving technologies make it an ideal choice for projects where performance, reliability and operating efficiency are equally important.
If you are looking for a reliable, energy-efficient rooftop HVAC solution for your facility, OPTIMA ROOFTOP is a system well worth considering.
