3/4" NPT. WELL ASSEMBLY FOR T675, T678, & T991

The Honeywell PV4100-3, 4-1/4" Insertion, 1/2" Diameter Copper Well Assy (#1728) is an essential component for the thawing of refrigerant in most models of the Honeywell T675, T678 and T991 refrigeration machines. This assembly also features a 1/8" I.D. stainless capillary tube.

The T75-160 Adapter Kit is designed for use with the T678, T991, and T991C Electronic Air Cleaning System Filters. The kit contains four (4) 3/4" NPT stainless steel well adapters and a filter wrench for use with the electronic air cleaning system filters.

The T678 1/4" Insertion Nozzle for the Honeywell L7580G-85440A small spot lasermeter. The T675 1/2" spring loaded flush nozzle provides a vapor free path between the laser cavity and the measurement point.

The T675 Series features: (1) Instantaneous, total power failure backup; (2) Adaptive load control for efficient operation under various pump and fan conditions; (3) Universal input voltage of 208/240 VAC. The T678 Series features: (1) Instantaneous, total power failure backup; (2) Adaptive load control for efficient operation under various pump and fan conditions; (3) Universal input voltage of 208/240 VAC.

Designed for sanitary (non-potable water) applications. This well assembly is highly efficient with low flow rates. The ½", Copper, threaded nipple is designed for the end user to install in wells drilled 4 1/4" and deeper.

The T775 and T788 are Used in the Control Systems of Airless Paint Sprayers. They Operate as an Interruptible Flow Restrictor, an Initiator of System Pressure, a Shutoff for Paint Discharge to a Separator Tank when the Spray Gun is Removed from the Gun Mounting, and a Displaced Volume Measurement to Trigger Warning Devices and to Control the Pump Start-Up. The T991 provides the same functions as the T775 and T788 plus it will Balances the System Pressure within 10 psi (0.7 bar), and it Monitors the Fluid Levels

The 1728 Well Assemblies are made from high quality bronze. They are designed for a wide range of measurements that do not utilize flow control.
