Featured Program

Large tonnage Trane CenTraVac™ chillers are now available for industrial buildings, data centers, and higher education facilities with R-1233zd (Honeywell Solstice® zd). In addition, Trane will launch a small tonnage CenTraVac chiller for offices and municipal buildings, early next year.

CenTraVac Chillers are reliable, efficient, low emission, and quiet. As part of the Ingersoll Rand EcoWise™ line, they are designed to lower environmental impact with next-generation, low-GWP (global warming potential) refrigerants and high efficiency operation. If you are interested in an upgrade, we also provide a service option to convert existing CenTraVac chillers with R-123 to R-514A—Chemours’ next generation, low-GWP refrigerant.
