Refra » Propane Chillers
Refra designs and manufactures advanced R290 propane chillers for industrial and commercial applications. These HVAC chillers provide high efficiency, stable temperature control and reliable performance in demanding environments. Using R290, a natural refrigerant with ultra-low global warming potential, these systems meet the latest EU F-gas regulations. Refra R290 chillers comply with EN378 safety standards and integrate advanced technology to ensure safe and consistent operation. Built for durability and flexibility, Refra industrial chillers combine custom design with easy maintenance, helping to reduce long-term operational costs.
GREEN COOLING | Refra has over 10 years of experience in manufacturing sustainable refrigeration systems with natural refrigerants like R290, R744, and R1270, supporting the shift toward low-carbon cooling.
Air cooled chillers remove heat from a process or environment by transferring it to the surrounding air through a coil and fan system. They are self-contained and typically installed outdoors, eliminating the need for cooling towers or additional water infrastructure. This design makes them ideal for locations with limited indoor space or restricted water access, while also reducing installation complexity and ongoing operational requirements.
Liquid cooled chillers use water or other fluids to absorb heat from the cooling system and release it through a cooling tower or external heat exchanger. Known for their efficiency and precision, they are well-suited for large-scale or high-demand environments where space or air circulation is limited. These systems provide stable, continuous cooling performance, making them a preferred choice for industrial plants, data centers, and commercial buildings.
Chillers with free cooling improve energy efficiency by using ambient air to assist or fully handle the cooling process when outdoor temperatures are low enough. Bypassing the compressor and transferring heat directly through a heat exchanger, these systems reduce power consumption. Ideal for cooler climates or processes requiring year-round cooling, they help lower operational costs and environmental impact while extending the lifespan of mechanical components.
