Ingersoll Rand Compressor R132

Check - Connections and hoses for leaks

A coolant level sight glass is located on the side of the separator tank. While the compressor is running under load, coolant should always be visible in the sight glass. The normal position is half way. The compressor should be running for at least 40 seconds for this check.

Stop the compressor, ensure the sump pressure is 0 psig and ensure the coolant is still visible in the sight glass.

Run the compressor for a minimum of 40 seconds. The coolant level should be visible in the sight glass. If not:

2. Isolate the compressor from the external air system.

3. Press the emergency stop to vent the separator tank and airend.

Air compressor operating temperatures will be higher than normal if the external passages between the fins of the cooler cores become restricted with foreign material. Regular cleaning of the cooler surfaces will support the reliable operation of the air compressor system, improve the life of the compressor coolant and improve overall compressor efficiency.

When performed frequently as determined by site conditions and airborne contamination, more significant cleaning or replacement may not be necessary.

2. Isolate the compressor from the system.

3. Press the emergency stop to vent the separator tank and airend.

Fixed speed compressors can take more than two minutes to fully de-pressurize once stopped.

4. Ensure that the main power disconnect switch is locked off and tagged.

For any required lifting of air compressor parts or required tools, always use the proper certified lifting equipment, and employ sound working principles.

Replace Food-grade Lubricant (Ultra FG)

Replace Separator element (if using Food-grade Lubricant)

With the compressor running on load, check the separator differential pressure via the controller. It will be necessary to change the element if the differential pressure equals zero or exceeds 1 bar (15 psig).

For R30-37, separator cartridges change procedure is as follows,

1. Stop the machine, electrically isolate and vent all trapped pressure.

2. Loosen separator cartridges with the correct tool.

3. Remove the cartridges from the housing; place in a sealed bag and dispose of safely.

4. Clean the mating faces of the housing.

The flexible hoses that carry coolant through the cooling system may become brittle with age and will require replacement. Replace them as needed or every four years.

1. Depending on the location of the hose, it may contain compressor coolant. It is recommended to drain the coolant into a clean container. Cover the container to prevent contamination. If the coolant is contaminated, replace with new coolant.

3. Install the new hose and refill the compressor with coolant.

4. Start the compressor, check for leaks and check coolant level. Refill as necessary.

Warning: This maintenance check requires trained personnel with PPE!

Is the no loss drain trap checked daily?

Press the test button on the drain and listen for condensate / air passing through the drain. Is it functioning correctly?

If the drain is clogged, what action was taken?
