General description
Rooftop solution is the most cost effective package solution for high efficiency comfort air conditioning of single volume buildings.
• First class efficiency system thanks to multiscroll compressor technology associated with chlorine free R410A refrigerant. The rooftop unit product line is Lennox most innovative equipment for commercial applications.
• eDrive variable speed direct transmission ventilation system to save even more energy on BALTIC and FLEXAIR ranges.
• Advanced eClimatic controller, designed to improve energy efficiency and reliability. This controller integrates master slave capability and a wide choice of communication interfaces.
• Cost effective package solution for fast and easy installation.
• Low weight construction for easy lifting in all site configurations.
• Many standard airflow configurations and wide range of adjustable roof curbs to suit all type of building designs.
• Multiple auxiliary heating options available, with intelligent control to allow the selection of the most efficient way to generate heating based on the outside temperature and/or energy costs.
• Fresh air control and free cooling/heating management for healthy and comfortable environments.
• Heat recovery solutions on exhaust air or to recover calories generated by refrigeration equipments
• The units are available with the following versions:
> Cooling only
> Heat pump
> Cooling only with gas burner standard heat or high heat
> Multiple fuels units combine heat pump with gas fired heating
EC fan technology
EC fan technology offers the maximum efficiency together with the minimum power consumption. That’s why BALTIC provides EC fans both in indoor and exhaust section.
For both supply and exhaust, the units can be configured up to 800 Pa external static pressure (ESP).
The EC plug-fan technology allows:
• Adapting airflow at commissioning
• Varying airflow during unit operation providing progressive inflation smooth /textile ductworks
• Easy maintenance operations, as there is not pulleys and belts regulation

The New Reference for Packaged Air Treatment Solutions
The new Rooftop eNeRGy is the adaptable Packaged solution offered by Lennox, to provide ventilation, cooling, heating and filtration functions for large volume buildings.
Main applications
• Industry/Logistic
• Commercial HVAC
Why this choice ?
• Indoor air quality
• Modularity and adaptability to any energy source
• Very high effi ciency
• Low thermal losses
• Optimized «Total Cost of Ownership» (TCO)
Modularity concept
Nowadays, buildings are taking advantage of the best construction techniques, and the different improvements in isolation and lightning technologies contribute to decrease the cooling or heating demands.
eNeRGy range is fully adapted to this new trend and can offer different combinations of thermodynamic refrigerant circuits with the same indoor airflow, giving different cooling or heating capacities
Architectural features
eNeRGy indoor section is built in an aluminum structure with double skin panels mounted with a special locking system to reduce air leakages to the minimum.
Double skin doors, panels, corners and roof offer a double-wall construction with 50 mm Rockwool insulation to provide an increased thermal resistance versus current ranges.
With a Fire class A2, s1, d0 (M0), this construction provides an increased thermal resistance (R=1, 43).
EC fan technology
EC fan technology offers the maximum efficiency together with the minimum power consumption. That’s why eNeRGy provides EC fans both in indoor and exhaust section.
For both supply and exhaust, the units can be configured up to 800 Pa external static pressure (ESP), whatever the options or accessories are chosen in the unit.
The EC plug-fan technology allows:
• Adapting airflow at commissioning
• Varying airflow during unit operation providing progressive inflation smooth /textile ductworks
• Easy maintenance operations ,as there is not pulleys and belts regulation
Filters
eNeRGy is fitted with G4 filters as standard and can offer as well, two higher levels of filtration as an option :
• G4+F7 filter option / efficiency > 85% / 0,4 μm particles
• G4+F7+F9 filter option / efficiency > 95% / 0,4 μm particles.
Heat recovery options
eNerGy range includes fully integrated modules to recover the energy from the installation.
Regarding the extraction air, eNeRGy offers two energy reco- very options :
• Rotary wheel
• Thermodynamic heat recovery circuit
Additionnaly, eNeRGy offers an option to recover the energy released by refrigeration equipments, called eRecovery.
