Brussels, Belgium, February 2, 2024 - Trane®, a leading global provider of indoor comfort solutions and services and a brand of Trane Technologies, announced Trane LEAF, its new generation of air-to-water heat pumps. Delivering heating and cooling capacities ranging from 8-30kW, Trane LEAF was designed to feature non ozone depleting and ultra-low global warming potential (GWP) R-290 (propane) refrigerant and provide sustainable comfort heating, cooling or domestic hot water production to light commercial and residential buildings.

“The Trane LEAF heat pumps seamlessly complement our extensive comfort heat pump portfolio, bolstered by the dedicated expertise of our highly qualified and trained service teams,” said Louis Rompre, portfolio leader for Trane in Europe, Middle East, Africa, Australia and New Zealand. ”Trane LEAF heat pumps are ideally suited for comfort heating and domestic hot water applications. Leveraging propane’s exceptional thermodynamic properties and near zero GWP, Trane LEAF not only allows customers to reduce direct emissions but also contributes to a significant reduction in both direct and indirect emissions. In regions where there's a growing emphasis on green solutions, this product stands out as a smart choice, aligning with our commitment to environmental responsibility."

In response to the evolving landscape of Climate and Sustainability trends, Trane LEAF aligns with regulatory changes, such as the revised European Union F-Gas Regulation, addressing concerns related to the greenhouse warming impact and decomposition of existing fluorinated refrigerants. R-290 (propane) is a non-toxic, refrigerant with a direct GWP of 0,02 and zero ozone depletion potential (ODP).

Key Features of the Trane LEAF heat pumps:

Versatile Operation: Trane LEAF excels in diverse conditions achieving elevated hot water temperatures in low outdoor air conditions. Operating optimally down to -20°C outdoor air, it delivers elevated hot water at +75°C even at 0°C outdoor air and +60°C at -15°C ambient temperature, making it an ideal solution for replacing gas boilers in light commercial and residential buildings.

Modularity Kit: Addressing larger heating demands (>30 kW), an optional modularity kit allows a configuration with up to 4 units, offering flexibility in meeting varying requirements.

BMS Connectivity: The integration of Building Management System connectivity via MODBUS TCP/IP or RTU enhances control and monitoring capabilities, providing users with advanced and seamless management options.

Full Inverter-Driven Technology: Equipped with a full inverter-driven scroll compressor, electronic expansion valve, and EC brushless fan(s), Trane LEAF achieves very high efficiency at all working conditions. This technology ensures optimal performance, contributing to energy savings and environmental sustainability.

The development of the Trane LEAF aligns with Trane’s and Trane Technologies' commitment to sustainable innovation. Providing sustainable cooling and heating solutions is part of Trane’s and Trane Technologies’ overall approach to reducing carbon emissions in the industries and markets they serve. It helps advance the 2030 Sustainability Commitments , including the Gigaton Challenge to reduce customer greenhouse gas emissions by 1 billion metric tons.
