Y-Type Strainer: The Guardian of LiBr Absorption Chillers
Hope Deepblue A/C, established in 1997 by the Continental Hope Group (CHG), stands at the forefront of energy-efficient cooling and heating solutions. Located in the National High-Tech Zone in Chengdu, China, Hope Deepblue A/C is the largest manufacturer of lithium bromide (LiBr) absorption cooling and heating equipment. We are dedicated to research and development, manufacturing, sales, and service across the fields of air conditioning, refrigeration, district heating, and industrial waste heat utilization. Our product portfolio includes LiBr absorption chillers, absorption heat pumps, and vacuum boilers, which are trusted by clients in over 30 countries and regions worldwide.
In the circulating water system of a LiBr absorption chiller, if waterborne impurities are not properly treated, they can easily lead to issues such as heat exchanger blockage, corrosion, and reduced flow, ultimately affecting the unit's operating efficiency and service life. To address this, Y-type strainers are typically installed at the inlets of the cooling water, chilled water, and make-up water circuits. Named for their Y-shaped appearance, these devices contain removable mesh filters that effectively capture sand, rust, and other particulate matter present in the water, thereby protecting the internal components of the unit.
Compact in structure and convenient to install and maintain, Y-type strainers serve as essential auxiliary devices to ensure clean and reliable system operation. During initial commissioning or when adding make-up water—when impurity levels tend to be higher—it is recommended to use fine mesh filters. Once the system is running steadily, the fine mesh may be removed and only the coarse mesh retained to reduce flow resistance. Regular inspection and cleaning of the filter elements are also necessary to prevent clogging, flow reduction, or increased pressure drop.
Although the Y-type strainer is a relatively small component within the refrigeration system, it plays a vital "gatekeeper" role in safeguarding the entire unit’s safe, stable, and efficient operation.
