Raypak Genuine OEM Cupro Nickel Tube Bundle, ASME, 266A/267A, 010369F

The Raypak 010369F is a cupro nickel tube bundle in the ASME rating. It is the genuine Raypak heat exchanger bundle, and the listing carries it for the 266A and 267A heaters.

Confirm the model first

The product data is not fully consistent on models. The title lists 266A and 267A, while the supporting description names CR265A, PR266 and 277A. Both readings come from the same source, so neither has been dropped here. A tube bundle is an expensive part to send back, so read the model and serial off the heater data plate and check them against 010369F before you order.

Why cupro nickel

The tube bundle is the part that transfers heat from the burner into the pool water. Copper nickel tubing is specified where the water is hard on plain copper, which covers salt chlorinated pools and any system where chemistry drifts. It costs more than a standard copper bundle and it lasts longer in those conditions.

The symptoms it fixes

A failed bundle usually shows itself as water where water should not be, dripping through the burner area or leaving the heater when everything is off. A scaled bundle behaves differently: the heater fires normally but cannot hold temperature, because the scale is insulating the tubes from the water.
