Opto-Matic oilers provide a constant level of oil in wet sump applicationsOpto-Matic® Constant Level Oilers
Opto-Matic Oilers provide a constant level of oil in a pump bearing housing, gear box, or other wet sump application. The Opto-Matic is the standard throughout processing industries. Stainless steel models provide long life in corrosive environments for the chemical, pulp and paper and mining industries.

  • One-piece glass reservoir ensures proper constant level function; there is no possibility of air leakage that would cause overfilling of the bearing housing
  • Adjustable level setting allows use in many applications
  • Multiple air vent slots provide for proper functioning at all times
  • Large surge chamber models help prevent oil overflow during machine start-up and shut-down
  • Side and bottom connections for simplified installation
  • BSPT connection ports available

Opto-Matic® Closed System Oilers
The Closed System Oiler is designed for all types of rotating equipment where a constant level must be maintained in a bearing housing. The closed system design prevents contamination and spillage, while the adjustable collar allows the oil level to be externally adjusted to the desired level.

The Watchdog is a closed-system oiler designed for wet sump applications.Watchdog® Oilers
The Watchdog Closed System Oiler is designed for bearing housings, gear boxes and other wet sump applications, and is ideal for use in the chemical processing, utility and pulp and paper industries. The Watchdog's viewport eliminates the need for separate ways of monitoring lubrication levels and replacing oil. Mounted on the centerline of the desired oil level, these constant level oilers do not require any adjustment or level setting.

  • Closed system design prevents contamination and spillage
  • Simplified installation with no vent line to pump bearing housing required
  • 2 oz. or 4 oz. reservoirs provide oil make-up
  • Integral viewport eliminates the need for separate installation
  • Three styles to choose from: an engineered thermoplastic body and reservoir, an aluminum body with glass reservoir and an aluminum body with thermoplastic reservoir

LCL large-capacity oilers

LCL Oilers
LCL Large-capacity Oilers provide a constant level of oil in a pump bearing housing, gear box, or other wet sump application. They operate on the same principle as the Opto-Matic Oilers and are used in applications requiring a large reservoir capacity. In isolated areas where refilling is a problem, LCL Oilers can save time and maintenance costs.

  • Large capacity glass or acrylic reservoir to 2-1/2 quarts; acrylic reservoir to 1 gallon
  • Side connection of 1/2 NPT makes for durable and rigid installation
  • Oil level setting may be raised by sawing or filing the beveled spout to desired height

Expansion chambers absorb the expansion of gases or fluids in closed systems.Expansion Chambers
Trico Expansion Chambers are designed to absorb the expansion of gases or fluids in closed systems. A rolling diaphragm provides a variable volume that, when properly sized, maintains chamber pressure at or near zero PSI. This reduced pressure build-up will extend seal life and help prevent leakage. Expansion chambers also protect the integrity of closed systems by eliminating the exchange of air from the chamber to the surrounding atmosphere. A choice of thread sizes and capacities offers flexibility to the user.

Watchdog® Air Dryers
The Watchdog Air Dryer is a passive drying system designed for bearing housings and other applications where moisture condensation must be minimized. Relative humidities are substantially reduced in most applications. Standby equipment can be protected from internal moisture damage when the Watchdog Air Dryer is installed.

  • 1" NPT port for easy installation in ANSI and API pumps
  • Desiccant cartridges change color to indicate when replacement is required; replacement takes less than one minute
  • Engineered thermoplastic provides high temperature rating and excellent corrosion resistance
  • Serves as both a viewport and an air dryer

AD-250 air drying system AD-250 Air Drying System
When a positive air pressure purge is desired for a pump bearing housing, this system can save you money and increase bearing life. Instead of using expensive argon or nitrogen gas, the -40° dewpoint of the Air Dryer allows use of ordinary compressed air to prevent damaging water moisture from entering the bearing housing. The AD-250's unique design dries the air at a high pressure and uses a downstream regulator to provide the correct pressure in the bearing housing and extend cartridge life.

Viewports are now available for a variety of applications, with 44 models to choose from. To resist corrosion, these viewports are offered in zinc-plated steel or brass bodies. The lenses can be removed in the field for cleaning, so you do not have to purchase and install a new viewport. Both NPT and BSPT thread sizes are available; lenses are available in 3-D plastic and flat glass styles.

Breather Vents
Trico Breather Vents are specifically designed for centrifugal pumps, or other applications requiring an exact exchange of air. With a choice of 6 thread sizes, these vents adapt to a wide range of equipment.

Sump Bottles collect water and contaminates in wet sump applications.
Sump Bottles
Sump Bottles are used as collection chambers on bearing housings and other wet sump applications. They collect water and contaminates, and have a drain plug for easy inspection and removal of fluids.
