Buffer Tanks

Buffer tanks are essential components in modern air conditioning and refrigeration systems, helping stabilize temperature, increase flow, and provide additional volume for both heating and cooling setups. Refra manufactures customized cold and hot water buffer tanks for commercial and industrial applications, offering both standalone models and integrated solutions with Refra chillers or heat pumps. An available heat recovery option allows reusing excess heat, helping to reduce energy consumption, lower operational costs, and support sustainable system performance.

Buffer Tanks For Cooling and Heating

Buffer tanks play a critical role in modern cooling and heating systems, improving efficiency, temperature stability, and energy management. In cooling setups, they act as thermal reservoirs—storing chilled water during low demand and supplying it during peak times—reducing compressor cycles and energy use. In heating systems, they store excess hot water, ensuring consistent heat output while minimizing wear on equipment. These systems are increasingly used in commercial and industrial refrigeration setups for their cost-efficiency and energy recovery potential. Adding a buffer tank ensures consistent fluid levels and helps avoid system disruptions.
