Rooftop HVAC Renewal for Esso Kalbakken Energy Station in Oslo

Project Information

Location: Oslo, Norway

Sector: Retail / Energy Station

Application: Heating and air conditioning for an energy station

Solution: Replacement of an existing KHA120 rooftop unit with a Redge eBBH035

Project Overview

```

Esso Kalbakken is an energy station located in Oslo, providing retail services in a busy commercial environment. For facilities of this type, maintaining a dependable indoor climate is an important part of supporting daily operations, creating comfortable conditions for employees and customers, and ensuring building services remain available throughout the year.

The site's existing rooftop HVAC installation had reached the stage where replacement was required. As rooftop units age, planned equipment renewal becomes an effective way to maintain heating and air conditioning performance while preserving the continuity of building operations.

The project therefore focused on replacing the existing rooftop unit while retaining the established HVAC configuration. This approach enabled the site's climate control system to be modernised without altering the overall rooftop installation concept.

```

Redge Solution

```

The HVAC upgrade involved replacing the existing KHA120 rooftop unit with a Redge eBBH035 rooftop unit.

1. Redge eBBH035 Rooftop Unit

The Redge eBBH035 was supplied as the replacement rooftop unit to provide integrated heating and air conditioning for the energy station. Installed in place of the previous KHA120 unit, it continues to support the building's climate control requirements through a single rooftop system.

By retaining the rooftop installation concept, the project renewed the site's HVAC equipment while maintaining an arrangement suited to commercial retail applications. The replacement provides an updated rooftop solution that continues to serve the operational needs of the facility.
