Preservation for Storage of ArielReciprocating Compressors

1.0 Purpose1.1 This document is to be used after an Ariel reciprocating compressor has been storedfor 12 months since its last preservation.

1.2 Following the procedures detailed in this document should prevent corrosion insidean Ariel reciprocating compressor for 12 months, provided the protection is notcompromised. If any deterioration is observed, or should the crankshaft be turned,re-preserve per ER-25.

1.3 This document is not applicable to the preservation of non-lube compressorcylinders and distance pieces. Non-lube compressors with VCI powder applied to thecompressor cyl inders and distance piece cavities should be inspected and preserved

per ER-34. This document is applicable to the preservation of non-lube frames andguides.

1.4 For a new compressor that will be stored longer than 12 months from the Arielshipment date, see Warranty Administration Procedure in the Ariel Packager Standards(ER-10.5.1), and apply for a Deferred Start-up status to extend the Standard Warranty.

2.0 Materials and EquipmentTo preserve compressor, use the following, or their equivalents:

2.1 A contact rust preventative such as Mobil Oil Corporation, Mobilarma 247 or CortecCorporation, VpCI 322.

2.2 A liquid vapor phase corrosion inhibitor (VpCI) such as Cortec Corporation (St. Paul,Minnesota) VpCI 329 or VpCI 322. These products are not compatible with polyglycol(PAG) synthetic oils . For PAG appl ications, consult Ariel Corporation (see page 7).The VpCI 329 and VpCI 322 are equivalent in strength and are compatible with eachother.

2.3 Waterproof backed tape: UV resistant Duct Tape such as Shurtape PC667.

2.4 Shipping covers and gaskets to seal cylinder suction and discharge openings.

2.5 Wax impregnated cloth: MARVELPAK #12 JAN-B-121F, TYPE I GRADE C,CLASS II. Available from EDCO Supply (Brooklyn, New York).

2.6 Priming pump if compressor does not have one.

2.7 Tarps and tie down materials if compressor is stored outdoors.

3.0 Procedure3.1 Inspection and preservation must be performed in a clean, dry environment.

3.2 To start inspection and preservation, remove the following:

Top cover.

Crosshead guide covers.

Duct tape and wax impregnated cloth from drive stub.

Suction and discharge nozzle shipping covers.

One crank end suction valve from each cylinder.

One head end suction valve from each cylinder.

If the compressor has been packaged, remove one discharge valve cap.

3.3 Inspect all internal surfaces and cavities of the compressor

Look for signs of corrosion,

Standing water.

Potential leak paths for water and air. If corrosion or standing water is found, photograph the affected areas and contact Ariel

Corporation (see page 7).

Remove water contamination and corrosion prior to coating parts with rust preventative.

Seal any leak paths that are found.

Ensure plastic plugs are tight and replace plugs that appear damaged.

Check exposed stainless steel tubing, making sure metal tubing caps are tight.

Inspect suction and discharge nozzle shipping covers and gaskets for damage.

3.4 Once inspection is complete, thoroughly agitate rust preventative and VpCI beforedispensing from the barrel. Use VpCI within 24 months of manufacture date. Spray all

internal compressor surfaces with a rust preventative such as Mobilarma 247 or CortecVpCI 322 if compatible with the compressor oil. Consult Ariel Corporation (see page 7) ifrust preventative is not compatible with compressor oil.

Spray rust preventative inside the frame, crosshead guides, and distance pieces, ensuringthat all internal surfaces are coated.

Spray rust preventative inside each compressor cylinder, covering all internal surfaces in thecylinder including the unloaders, piston rod, valve pocket surfaces, retainers, valve caps,suction and discharge gas passages, and valves.

Pre-lube the lube oil system before turning the crankshaft. Ensure that oil is visiblyflowing from all bearing positions and crossheads.

Rotate the crankshaft 360 degrees plus 180 degrees and re-spray all surfaces inside of the

frame, crosshead guides, distance pieces, and cylinder bores. There should be no noticeable accumulation of excess rust preventative in the bottom of

treated cavities.




3.5 Prime the lube oil system with a 50/50 mixture of compressor frame oil and rustpreventative such as Mobilarma 247 or Cortec VpCI 322 if compatible with frame oil.

If provided, remove the suction line from the pre-lube pump and use the pre-lube pump topump the rust preventative oil mixture through the lube oil system at a minimum of 10 psi for2 minutes.

If a priming pump is not provided, connect a priming pump to the Crankcase Oil Prelubeconnection located on the lube oil filter housing and pump the rust preventative oil mixturethrough the lube oil system at a minimum of 10 psi for 2 minutes.

Drain any excess rust preventative mixture from the frame and guides. Lube oil pipingshould remain filled with the rust preventative oil mixture during the storage period.

3.6 Add minimum quantity of VpCI corrosion inhibitor to the frame per TABLE 1. Apply bypouring or fogging the VpCI into the frame. When pouring the VpCI liquid into the frame,distribute evenly throughout the cavity. Do not pour VpCI directly on any bearing surfaces.

3.8 Add minimum quantity of VpCI corrosion inhibitor to the cylinder per TABLE 3. Applyby pouring or fogging the VpCI into the cylinder. When pouring the VpCI liquid into a cavity,distribute evenly throughout the cavity. Distribute 75% of the minimum quantity evenlybetween the cylinder suction and discharge gas passages. Distribute 25% of the minimumquantity evenly between the crank end and head end of the cylinder bore.

NOTE: 4. Inches x 25.4 = mm


3.9 If your compressor is not shown in the tables above, contact Ariel Corporation (seepage 7) to determine quantities of VpCI to be used.

3.10 Add quantity of Cortec VpCI 329 or 322 to the following cavities:

1/2 ounce of VpCI to the cylinder lube box sump via the fill plug.

1 ounce of VpCI to lube oil filter housings that are drained prior to shipment (This step is notapplicable to spin-on filters).

1/2 ounce of VpCI to discharge port of the lube oil pump.3.11 VpCI corrosion inhibitors require protected cavities to remain sealed during thestorage period. Open cavities will deplete the VpCI concentration, rendering the VpCIineffective. To prevent VpCI depletion, seal the compressor as follows:

Plug all openings including vents and breather connections making sure plugs are tight.

Reassemble all covers and the valve assemblies and re-connect the pre-lube pump.

Use shipping covers and gaskets to seal cylinder suction and discharge nozzles.

Check for proper installation of the cylinder shipping covers and gaskets.

Replace any damaged shipping flange covers or gaskets.

Hand-wrench tighten the shipping flange cover bolts in a criss-cross pattern.

3.12 Coat drive stub with rust preventative, wrap with wax impregnated cloth such asMARVELPAK #12, followed by waterproof backed tape such as Shurtape PC667.

3.13 Tape the clearance opening between the drive end dust seal cover and thecrankshaft to prevent any exchange of air to the frame and cylinders.

3.14 Tag the compressor and guide/cylinder assemblies, noting that the crankshaft shouldnot be turned and the date when the compressor was last inspected and preserved. If thecrankshaft is turned for any reason, re-preserve per ER-25.

4.0 Storage4.1 If the compressor is to be stored after being packaged, ensure that enoughVpCI and rust preventative has been used to protect all pip ing and bot tles in the

package, in addi tion to the compressor. Ensure that all openings in the package aresealed.

4.2 Al l Ariel reciprocating compressors must be stored in a clean, dryenvironment. If stored outdoors, the compressor must be protected from directcontact with the elements.

4.3 The compressor must never be stored with the mounting feet directly on theground.

5.0 Re-Commissioning Compressor to Service5.1 At commissioning, the oil fil ter must be changed. There is no need to change oil,or if drained to flush the frame prior to filling with oil, as the rust preventative will mix with thelube oil. Remove temporary covers, gaskets, plugs, tape, tags etc. used to seal thecompressor. Replace all connections including vents and drains.

5.2 Check fastener torque on all bolting which may have been loosened as a result ofapplying this procedure and all critical bolting as a result of re-applying the compressor toservice. Reference Ariel Technical Manual or toolbox torque charts for fastener torquevalues.

5.3 Utilize the Start-Up Check list in the Ariel Technical Manual or ER-10.4.0.
