More than ‘just a chiller’!

State-of-the-art design

Its very low unit height (< 2m) allows a discrete installation on a roof while ensuring a perfect architectural integration. On top, all thermodynamic and hydraulic components are installed inside the casing, protected by aesthetic grilles.

Increased life-time

Main components are installed inside the casing. Thus not only this design is elegant, it also improves product sustainability by protecting the main components against climatic conditions.

Acoustic comfort

The unit presents a quiet operation with the thermodynamic and hydraulic modules mounted in a soundproof technical cabinet. On top, flat top of the units hides the fans and reduces noise level. In addition, two noise level configurations are available.

High efficiency

The Neosys’ components ensure excellent seasonal efficiencies. On top, the eDrive technology allows the use of variable speed drive pumps, generating up to 75% reduction of the pump consumption.

Smart servicing

The Neosys metrics are accessible 24/7 through LennoxHydrocontrol and LennoxCloud. These enable permanent monitoring and local supervision and help predict maintenance operations, offering improved responsiveness.

Heat recovery

Additional options enable rejected heat recovery to provide free hot water for sanitary or industrial purposes.
