Project Overview
In the heart of France's Savoie wine region, Redge carried out a full HVAC
retrofit at a winery by replacing five rooftop systems originally installed in
2002. The outdated R407C-based units were retired after over 20 years of
service and replaced with advanced
eBALTIC rooftop units running on
R32 refrigerant---a more sustainable, lower-GWP solution
compliant with the latest environmental standards.
Working in close partnership with the site's long-standing HVAC contractor,
Redge ensured the replacement process was executed with minimal disruption to
ongoing operations and full respect for the facility's architectural
integrity.
Challenges
The site posed several retrofit-specific constraints:
-
Existing roof structure and ducting had to remain intact
-
Downtime needed to be kept to a minimum to maintain
production flow
-
The solution had to support energy efficiency and
regulatory compliance
-
HVAC performance had to remain stable in a
sensitive production environment
Noise management and reliability were also critical due to the facility's role
in the regional wine supply chain.
Redge Solution
Redge selected the eBALTIC rooftop range for its compact
format, retrofit-ready design, and improved component efficiency.
Key features of the solution included:
-
R32 refrigerant, offering low GWP and PFAS-free performance
-
EC plug fans, replacing legacy belt-driven components to
reduce energy use and improve acoustics
-
Built-in smart regulation, optimizing energy consumption
across variable loads
-
Adaptation curbs, which allowed seamless installation on
existing roof openings without structural modification
The new rooftop systems delivered substantial gains in thermal performance
while reducing both operational costs and environmental impact.

eBALTICrooftop range for quick, sustainable upgrades in industrial and production
environments.
Key Outcomes
The winery now benefits from:
-
A modern HVAC platform compliant with the latest
refrigerant regulations
-
Enhanced airflow efficiency and
low-noise operation
-
Reduced maintenance frequency and improved lifecycle
economics
- A future-ready system supporting sustainable production practices
This successful retrofit demonstrates how Redge helps blend tradition and
innovation---modernizing vital infrastructure while preserving the quality and
integrity of the production environment.
