We have changed the design to optimize the product structure. The new generation RFKH platform has been optimized maintaining piping connections with no installation impact as below:
Valve body - Compact design leads to smaller installation space. Connection size and position remains the same, so it can be quickly switched between new and old series.
Superheat Adjustment end - Deep into the valve body, screwdriver is easier to locate making it more difficult to slip out when adjusting.
Installation part - Structure optimization and upgrade, results in time saving during installation - more convenient, reliable, and easy to adjust.
Orifice - The same performance as last generation (same cooling capacity) allows you to direct switching between new and old series.
