Field Sensitive "BULLET" Proximity Switch

Stop Cold Weather Compressor Shutdowns and Broken Spring Problems

The Problem:
Premature/phantom shutdowns in cold weather or when the compressor is operating at high discharge pressures are directly attributed to the current design of the oil filled, spring loaded proximity switch used with No-Flow Shutdowns such as the DNFT, ProFlo products and Proximity Switches.

The Cause:
Why does the oil filled, spring load magnet assembly cause phantom shutdowns? The DNFT, ProFlo Jr., ProFlo PF1 and proximity switch housings are spring loaded and full of oil. When the divider block piston pushes the magnet of the proximity switch into the housing, the oil behind the magnet is forced back into the divider block with each piston cycle. When the outside temperature drops to a specific range, the oil in the housing becomes very thick and creates higher pressure in the system. The cold oil trapped in the magnet housing causes the divider block to stall, then slams the magnet in to the housing causing the spring to break, causing the no-flow device connected to the control panel to go into alarm state, shutting down the compressor. The same scenario can also take place when the compressor is operating at high discharge pressures and utilizes high viscosity oils (ISO 460 - 680).

The Solution:
"PATTON FIELD SENSITIVE "BULLET" PROXIMITY SWITCH" Fluid flow in the divider block moves the piston within magnetic range of the end of the switch, the internal magnet in the switch moves towards the piston and closes the dry contacts, sending a switch closure signal to the PLC, No-Flow or "MinuteMan" shutdown in the control panel. The Patton "BULLET" proximity switch is not affected by oil viscosity switch or temperature and is designed for use with all divider block systems.

Low and High Pressure Filters

B118-A Delta-P Filter Assembly

The Patton "B118-A Delta-P Filter Assembly" is a low pressure non-bypass in-line filter. The low pressure filter must be installed upstream of the lubricator pump in the oil supply line. The B-118 filters trash out of the oil supply eliminating pump failure caused by debris in the oil. The delta-p across the filter is displayed on the 2" liquid filled pressure gauges to alert the operator when, "It's Time To Replace The Filter."

SSFH-10ML High Pressure Filter

The Patton "SSFH-10ML" High Pressure Filter should be installed in the oil supply line on the discharge side of the lube pump to remove suspended debris down to 10 Micron. Filtering oil eliminates divider block and check valve failure caused by trash. All divider block systems should have a high pressure in-line filter installed to increase reliability.

"MinuteMan" No-Flow Shutdown

Revolutionary Design

The Minuteman no-flo device can be mounted anywhere on the compressor frame, skid, control panel or wall mount because it is no longer coupled mechanically to the proximity switch. The operation can be set to either a normally open or normally closed configuration. The Minuteman No-Flo device has a Form C alarm output as well as a traditional LED proximity switch pulse indicator. This fully encapsulated device comes with a 2 year factory warranty and can operate in temperatures from -4 degrees C to +80 degrees C.

Patton HP Divider Block

When You Can’t Afford Failures or Downtime!

Positive Lubrication:
The Patton HP divider block assemblies have the tightest piston to valve tolerance in the world at 80 to 90 millions-of-an-inch! This incredibly tight tolerance both ensures precise amounts of lubrication to vital components as well as superior piston stalling for positive shutdown of the system if any lubrication point plugs.

High Pressure Capability:
The Patton HP divider blocks are designed to be assembled and mounted with reduced torque of only 65 inch pounds. This assures a leak free operation to 7,500 PSI.

More Piston Options:
Patton HP divider block pistons come in more sizes so systems can be designed to deliver lubrication quantities at a more efficient rate. This saves money in lubrication costs.

O-Ring Outlet Checks:
Patton HP divider blocks come with O-Ring outlet check valves. This reduces leak paths and assures the reliable operation of your divider blocks.
