Randell Expansion Valve Base
This Randell Expansion Valve Base is used to control the amount of refrigerant you have flowing into the evaporator coil. Randell units have separate cooling for the base unit and for the rail. Allowing for more efficient cooling and energy usage. At night you can turn off the rail and keep your base cold with all of your toppings inside. This valve will prevent you from having too much refrigerant being sent to your evaporator coil, too much refrigerant will freeze your toppings instead of just keeping them chilled. Too little refrigerant will not keep your toppings cool enough to be able to serve them to your customers. This is an integral part to your Randell unit and you want it to be functioning correctly.
