Fluid Temperature Sensor (FTS)
Graco eliminated additional fittings that were necessary to install the FTS in-line with Reactor heated hoses. Now, the metal bodies of both the molded FTS and the FTS spacer are machined with the proper thread connections. One side of the FTS is machined with a female JIC thread and the other side with male JIC threads. No changes were made to the thread type or to the hose fittings. The changes to the FTS are retro-fittable to all hoses in the field. The easiest way to install the new FTS is to attach the male hose end to the FTS first, then install the female hose end to the FTS.
Graco has also changed the molding process used on the FTS. The new FTS has a cleaner, more aesthetically finished look, including the Graco logo molded into the part.
Immersion Heaters
The immersion heaters used on all Reactor fluid heaters have been changed from a two-piece design to a one-piece design. The old design required a fitting reducer nut, which included an o-ring, to be used with each immersion heater.
The new design eliminates the need for a fitting reducer nut by incorporating the reducer nut as part of the immersion heater saving time and money on maintenance. No changes were made to the thread type used on the fluid heater block. This change is retro-fittable to all fluid heaters in the field.
To install the new immersion heater into a fluid heater block currently using the old style immersion heaters, the fitting reducer nut must be removed from the fluid heater block before installing the new immersion heater.
A summary of old and new immersion heater parts numbers is as follows:
- 15B138 is superseded with 16A110 and o-ring 124132
- 15B139 is superseded with 16A111 and o-ring 124132
- 15B140 is superseded with 16A112 and o-ring 124132
