Recharging/refilling refrigerant in a chiller?

[Coral reefer]

Anyone ever refilled a chiller before? Have one that isn’t cooling enough anymore. Not sure how hard or expensive or possible it is to refill the refrigerant?

it’s not hard to do if the chiller piping has factory schrader valves. If the unit doesn’t come with them. You will need to “pierce the tubing with an adapter, (kinda like the kind that straps to your water pipes when hooking up a RODI unit under your sink. And that can be a pain in the A^*.
