Trane – by Trane Technologies (NYSE: TT), a global climate innovator, has announced the new Trane® Hydronic Branch Conductor that helps retrofit and new buildings achieve higher energy efficiency and zone comfort from decarbonized, electrified heating and cooling without major structural disruptions. The Hydronic Branch Conductor supports simultaneous heating and cooling capabilities, improving heat pump heating efficiency by more than 35%.
“To advance the decarbonization of buildings, we need innovations that simplify the retrofitting process from fossil fuel systems to heat pumps,” said Oakley Roberts, Vice President of Product Management, Commercial HVAC Americas, Trane Technologies. “The Hydronic Branch Conductor from Trane is an excellent example of such an innovation, effectively addressing this challenge in hydronic-based thermal systems.”
The company is expanding its portfolio of chillers, adding three efficient, sustainable process chillers. “The recent acquisition of Italian-based manufacturer MTA has strengthened our sustainable HVAC offerings and today we announce Trane’s first series of process chillers built specifically to meet the cooling needs of manufacturers, including pharmaceutical, food and beverage, and automotive manufacturers, among others,” added Roberts.
Trane has also announced it has transitioned Series R™ RTWD and RTHD models and the remainder of the AxiomTM Water Source Heat Pumps portfolio to low global warming potential (GWP) refrigerants.
Trane® Hydronic Branch Conductor Improves Building Efficiency, Sustainable Comfort
A practical path to decarbonization for new buildings and retrofits, the new Trane Hydronic Branch Conductor is a system component that enables the repurposing of existing cold-water piping for both heating and cooling distribution, even in buildings with existing two-pipe branch systems, to help achieve sustainable comfort with minimal structural changes and installation costs.
When it is paired with hydronic heat pump systems, building owners and managers can:
- Change heating and cooling loads area by area multiple times a day without the need to switch from hot to cold water seasonally for the entire building.
- Replace six-way valves at each terminal unit on a branch with a single conductor.
- Convert existing buildings with 140 to 180 degrees Fahrenheit hot water (60 – 82 degrees Celsius) to a more energy efficient 105 degrees Fahrenheit hot water electrified heating supply (60 degrees Celsius).
The Hydronic Branch Conductor is ideal for education and government buildings, commercial offices, hotels, medical offices, and high-rise residential buildings with multiple thermal zones.
Trane Chillers
Purpose-Built Process Chillers for Industrial Process Cooling Available Through Trane
Following its acquisition of MTA, Trane now offers chillers purpose-built for industrial process cooling, with different cooling capacities that meet the specialized needs of pharmaceutical, food and beverage, automotive and general manufacturers, and more.
Fully packaged with a compact design, the TAEevo TECH and TAEevo TECH MINI are well-suited for indoor and outdoor applications that have space constraints. The TAEevo TECH has a nominal cooling capacity of 2 to 53 tons and the TAEevo TECH MINI has one ton. These models also have:
- A finned-tube evaporator to provide lower pressure drop and reduced fouling.
- Cleanable, removable aluminum condenser air filters and hail guards for added condenser protection and ease of maintenance on units from 3 tons and under.
- Pre-packaged on-boarding pump(s), coolant buffer tank, and controls for plug-and-play installation.
- An insulated, pressure-rated tank for a steady supply of cold process fluid that operates as an open or closed loop.
Series R™ Helical Rotary Screw Chillers
Building on a legacy of trusted performance, these two proven, modernized workhorses continue to meet evolving industry needs.
Series R™ Model RTWD (80-250 tons; 600 – 3,000 MBH)
Now with expanded heating capabilities and low-GWP refrigerants.
To meet your evolving needs, RTWD chiller heat pumps now offer expanded heating capabilities of up to 165 °F (74 °C) for boiler replacement in a wider range of applications. RTWD chillers can help meet building codes for heat recovery and use low-GWP R-515B refrigerant for heating or R-513A for cooling. RTWD chillers also feature our Symbio® 800 equipment controller.
