Dave Kingston, Group Training Officer at Aspen Pumps, says choosing the right tools can help achieve the perfect joint.
Traditionally, the method of joining two pieces of copper tube together is by using a standard tube expander and brazing the joint. When expanding a tube, ensuring that the result creates a straight clean expansion, means less chance of a sloppy fit and the joint falling apart during assembly. By expanding one end and sliding the other tube into it, there is only one join to braze; this results in less chance of a refrigerant leak.
Dave Kingston, Aspen Pumps Group Training Officer, looks at the equipment needed to work with a refrigerant that is growing in popularity.
CO2 (R447) offers the lowest practical GWP (global warming potential) of all the common refrigerants and as such is rapidly growing in popularity, given the GWP quota reductions the industry is tasked with implementing.
The tools required for installation and maintenance need to be heavy duty, due to the pressures associated with this refrigerant. JAVAC supplies a full range of manifolds, charging equipment and leak detection specifically designed for the application.
Introducing the updated Javac service manifolds… redesigned to meet the ever-changing needs of engineers and the industry.
The rising price of R410A, coupled with the growing influence of F-Gas regulation, now mean a large number of jobs are switching to the lower GWP-rated R32. Therefore, Javac has developed and redesigned its R410A manifolds to be dual scale and include both R410A and R32. This adds to the versatility of the Javac manifold series, allowing the installer to tackle both older R410A reclaims and new R32 charging. The Javac manifolds are available in 2-valve or 4-valve models.
