US Cellar Systems, a California based wine cellar manufacturer that we work closely with recently announced an important new innovation in one of their commonly used components. The LRC Expansion Valve is now externally equalized. Learn how this is to be installed and some of it’s performance advantages.
The Expansion Valve by LRC
New Expansion Valve
The LRC Expansion Valve looks almost like a pressure regulator, mounted inside one of the US Cellar Systems refrigeration system for wine cellars. It is a common component in all of the series offered by US Cellar Systems, except for the CC series.
Installation of the New System by LRC
When installing, add a T with an access shrader. This has a key advantage. You will be able to measure your evaporator coil pressure at the evaporator, instead of having to go all the way out to the condensing unit to look at your gauges. This makes adjustments to your system much more convenient.
Wine Cellar Refrigeration System Adjustment
Adjusting Your Expansion Valve by LRC
Use a 3/8” nut driver or a ratchet and a 3/8” socket.
You can adjust the valve by turning the head on the top of the regulator. To increase pressure you turn clockwise. To decrease pressure you will turn counter-clockwise.
Caution! Remember to make small adjustments. Never go all the way in with the adjustment. If you go too far in you can damage the diaphragm and then the expansion valve will no longer adjust. This damage will not be covered under warranty, so be very cautious when making adjustments to prevent such harm to the system.
