Scottfrio Introduces High-Quality Y-Type and U-Type Refnet Joints for HVAC Industry, Following Japan's Lead

Daikin, a powerhouse in the HVAC industry renowned for its innovative solutions and dominant market presence, has played a pivotal role in shaping the industry's standards. One such example is the transition from Y-type to U-type Refnet Joints, a change that has been embraced by Daikin and has gradually influenced the market.

The decision to switch from Y-type to U-type Refnet Joints stems from practical installation considerations. The Y-type joint, while once widely used, proved to be more susceptible to damage during installation, especially in the central section, leading to potential leaks. Recognizing this challenge, Daikin led the industry in adopting the more robust and installer-friendly U-type joint.

While Japan has adopted the U-type joint due to its advantages, such as easier installation and reduced risk of damage, many markets worldwide still prefer the Y-type joint due to traditional installation practices. However, it's essential to note that the U-type joint offers superior flow distribution, with equal pressure on both sides, compared to the Y-type joint, where there is a pressure increase on the bent side. This distinction is crucial in understanding the practical differences between the two types. Despite the industry's historical preference for the Y-type joint, Daikin's proactive stance and the availability of high-quality Y-type and U-type Refnet Joints from manufacturers like Scottfrio are gradually driving the industry towards adopting the more efficent U joint.


Scottfrio, a manufacturer capable of producing both Y-type and U-type Refnet Joints, ensures the quality and reliability of its products through stringent testing procedures, including leak tests and salt spray tests. This commitment to quality aligns with Daikin's ethos of delivering excellence in every aspect of HVAC solutions.

As the HVAC industry continues to evolve, Daikin's influence remains profound. By spearheading innovations like the transition to U-type Refnet Joints and collaborating with manufacturers like Scottfrio to offer high-quality products, your business can do better
