HIT Series

It divides the refrigerant of one outdoor unit into multiple indoor units to be able to control one zone independently. That specific flow will assist in maintaining the pressure of the system in equilibrium, allow you to both heat or cool efficiently at once and drive the entire VRF system towards the most energy savings possible.

Copper is an excellent conductor of heat and therefore, it conducts heat well, and copper does not rust thus lasts longer. It is compatible with the high pressures of modern refrigerants and this makes it efficient, prevents leaks and provides you with the reliable performance over the years in those complex, expensive VRF systems.

Yep. Their multi-step design allows them to fit various standard pipe sizes hence making them universal. It means that contractors are able to apply them to numerous projects, which are easier to hold in stock and which will always be in the right place.

Because 5.2 MPa is roughly equal to 754 PSI, it shows that the VRF Y Joint has been hydrostatically tested at that pressure and has held up without any sign of leakage. In practical terms, this gives you the confidence that it will perform reliably under normal system operating conditions.

The XLPE insulation, which is fitted to the factory as fire-grade is laser-cut to fit perfectly. It prevents condensation, eliminates on-site insulation, accelerates installation and provides consistent heat protection without any gaps. That exact fit appears clean and contributes to the overall system remaining energy efficient.

To avoid oxidation and copper oxide, first use nitrogen during brazing. Ensure that the pipes are well supported and sloped in order to allow oil to be returned. Use a dry, clean and tight method. The next step is to check the entire circuit functionality by running a test pressure decay and vacuum test once installed.

Of course. Constructed of premium copper and pressure tested, the HIT Series is compatible with contemporary low-GDP refrigerants such as R-32. Its powerful design addresses the demands of such environmentally friendly coolants to ensure the safety and future-proof performance is reliable.

The HIT Series comes with CE and ISO certification, follows RoHS guidelines, and is built to meet AS 4041 requirements as well.

The right selection really comes down to the system capacity, how many indoor units are being connected, and, most importantly, the refrigerant pipe size. If you check the VRF project specifications along with our detailed datasheets, our engineering team can then help you choose the model that fits the application properly.

We work with high-purity copper, and the brazing is done in an automated setup where nitrogen is continuously passed through to keep the tubing clean from the inside. Once that’s complete, each unit is pressure-tested at 5.2 MPa (754 PSI). By the time it’s ready for dispatch, it has already gone through several checks to make sure it will perform on site without any leakage issues.
