Trane Flex2O Chillers and Heat Pumps with Increased Connectivity, Flexible Control and Bigger Capacities

The Flex2O water-cooled chillers and water source heat pumps are now available in up to 700kW capacity from a single unit, and with the new Trane Symbio™ Controller for increased flexibility, serviceability and connectivity.

Brussels, April  14, 2021 – Trane®, a leading global provider of indoor comfort solutions and services and a brand of Trane Technologies, announced today the latest upgrades in the Flex2O range of scroll water-cooled chillers and water source heat pumps. The Flex2O units, designed to provide all year round comfort and process cooling and/or heating efficiency within a small footprint, are now available in up to 700kW of capacity from a single unit and feature the new Trane Symbio™ 800 controller for building automation and connectivity.

The compact, modular design of the Flex2O offers scalability and flexibility of configuration allowing to combine up to six units to meet the building’s capacity and performance requirements. With the increased capacity by the single Flex2O unit, building owners and facility managers now can easier adapt their system’s capacity to the changing heating and cooling demand throughout the lifespan of the building.

The Symbio™ 800 connected controller brings more value giving business owners and servicers the remote performance monitoring, tracking and controls to manage cooling and heating processes remotely when they aren't on location.  With Symbio™ 800, the Flex2O units now come standard with outputs for easy connectivity to building automation systems. This allows smaller buildings to enjoy the benefits of connectivity and leverage expanded diagnostics capabilities, including remote monitoring and service interface accessible via standard web browsers.

Louis Rompré, portfolio manager at Trane Europe: Improving efficiency, performance, sustainability, serviceability, connectivity - at Trane we’re continuously looking at ways to enhance our systems so our customers can easier fulfil their comfort and process cooling and heating needs. The upgrade of our Flex2O portfolio is just another step on our journey towards continuous innovation. Within our robust screw, scroll and maglev portfolios, we give our customers the flexibility to choose the right technology and solution for any of their applications – and the opportunity make their buildings perform better and be more climate friendly.

The Trane Flex20 water to water heat pump units meet the highest Ecodesign efficiency class A+++ and address the environmental and sustainability efforts in urban areas offering an efficient alternative for traditional gas or oil fuelled boilers and compatibility with geothermal applications.
