Recommendations for Equipment Storage

1. GENERAL
  1.1 All unpainted surfaces to be covered with corrosion preventative.
  1.2 Extreme heat or cold to be avoided. Storage temperature range to be between 10°C-38°C.
  1.3 Storage to be in a dry location. If equipment is stored in the shipping containers, "moisture absorbent" material should be placed in the container prior to storage. For warehouse storage, the equipment should be covered, the equipment should be well ventilated and the air in the warehouse to be dehumidified.
  1.4 Security to prevent loss or damage should be provided.
  1.5 Overhead cranes or portable cranes of adequate capacity to be available to unload, move and load the equipment safely and correctly.
  1.6 Storage area to be clean and free from dust and other contaminants.
  1.7 Equipment to be stored in the original crates or on the original skids provided by Reichel & Drews. Skid mounted equipment to be loosely covered with tarps to keep equipment clean, but allow air movement.
  1.8 Store equipment out of direct sunlight.
  1.9 When equipment is removed from storage, bearings should be purged of the original grease and filled with new grease.

2. ELECTRIC MOTORS
  2.1 Motors, if not mounted on the equipment, are to be stored in the original crates.
  2.2 The storage area is to be free from any vibration.
  2.3 Bearings:
    a. Ball and roller (anti-friction regreasable type). The bearings are to be fully greased at the time of going into extended storage. Motor shafts are to be rotated manually every 6 months and additional grease added in the bearings cavity. Rotate shaft by hand before putting into service.
    b. Ball (anti-friction non-greasable). No additional bearing precautions are necessary.
  2.4 All drains to be fully operable while in storage, and/or drain plugs removed. The motors to be stored so that the drain is at the lowest point. All breathers are automatic "T" drains must be operable to allow breathing at points other than through the bearing fits.
  2.5 Windings to be megged at the time equipment is put into storage. At the time of removal from storage, the resistance reading must not have dropped more than 50% from the initial reading. Any drop below this point necessitates electrical or mechanical drying. Where a large quantity of motors is stored, an inspection or sampling should be made by removing the end brackets and visually inspecting for the presence of water in the grease or rust on the bearing. If present, replace the bearings and relubricate.
  2.6 All external parts and motors subjected to corrosion to be protected by corrosive resistant coating.
  2.7 Where motors are not stored in the original containers, but are removed and mounted on other pieces of machinery, the mounting must be such that the drains and breathers are fully operable. In this respect, the drains must be kept at the lowest point on the motors and/or the drain plugs removed so that all condensation can automatically drain out. All other storage conditions apply, including rotation of motor shafts. Where such conditions cannot be met, then the equipment must be treated the same as if it were mounted in its normal position, and all protective devices such as heaters, breathers, and drains fully operable.

3. GEAR REDUCERS
  3.1 Lubrication. Reducers have been filled at the factory with sufficient lubricant for their specific mounting position.
    Do not add or remove oil upon installation or change oil after break-in. Change oil only when performing maintenance that requires gearbox disassembly. If oil must be replaced, use oil in accordance with manufacturers' recommendations.
  3.2 Venting. Do not remove, paint over or obstruct vent plugs.

4. ELECTRIC CONTROLS
  4.1 Motor Control Center
    a. Store the motor control center with a heavy duty plastic or similar material to prevent the entrance of foreign particles.
    b. Motor control centers, which are not installed and energized immediately, should be stored in a clean dry space. Storage temperature should maintained between -30°C and +65°C (See NEMA ICS 1-108.03). If storage temperature fluctuates or if humidity exceeds 60%, space heaters should be used to prevent condensation. Preferably, motor control centers should be stored in a heated building having adequate air circulation and protected from dirt and water.
    c. Motor control centers that are designed for indoor applications do not have sufficient packaging for outdoor storage. Additional packaging for protection from outside elements and temporary electrical heating to prevent condensations should be installed. A space heater rated at 200 watts per section is adequate for the average motor control center. All loose packing or flammable material should be removed prior to energizing space heaters.
    d. Unenergized motor control centers for outdoor use should be kept dry internally by installing temporary heating (see item 3) or by energizing optional self-contained space heaters.
  4.2 DC Drive Equipment
    a. Motor-Motors are enclosed. Be sure all covers are on tight. Keep temperature between 0°C and 50°C.
    b. Drive cabinet and operator's station -- Put silica gel in both cabinet and operator's station. Be sure both are closed. If any holes were cut, plug with duct seal and/or duct tape. Keep temperature between 0°C and 50°C.
  4.3 Process Control Equipment -- The process control equipment should be stored indoors in a heated/air-conditioned room.
  4.4 Honeywell (Temperature) Control Valves -- None of the products require other than normal storage conditions. "Normal" is defined as conditions free from heat or cold (50°F to 80°F storage temperature preferred), and where the products are kept dry and protected from dust. Other products should not be stacked on them. If these conditions are met, the products should perform to specifications when they are put into service.

5. ASPHALT AND COMPOUND VALVES
  5.1 Every six months a new lubricant stick should be put in the valve and it should be cycled. This lubricant stick, Resun #101, comes 24 sticks per box.

6. ASPHALT PUMPS
  6.1 Store the pump unit indoors.
  6.2 Coat the wetted internal parts with a rust inhibitor oil. Use an amount that is sufficient to coat all the surfaces. Do not fill the casings.
  6.3 Seal the port openings after coating the parts.
  6.4 Optional: Rotate the pump shaft, one or two turns, once a month.
  6.5 Spray a rust inhibitor oil on any unpainted, exposed shaft.

7. THERMAL FLUID HEATER
  7.1 Use a desiccant drying agent in the electrical panel. The coil should be okay, if the heaters are stored indoors. The only problem would be with the contacts on the electrical panel rusting.

8. VALVES AND CYLINDERS
  8.1 No special treatment is required for valves. On cylinders, all exposed steel (tie rods, screws, cylinder rod ends, etc.) should be coated with light oil. When the cylinders are taken out of storage they should be cycled a number of times to allow the seals to return to their normal condition.

9. MISCELLANEOUS MECHNICAL COMPONENTS
9.1 Belts and Seals -- These items should be stored in a moisture free/dry environment. To prevent degradation the environment should be ozone free and the belts and seals should be kept out of direct sunlight.
  9.2 Bearings -- Bearings should be packed full of grease for storage. The environment should be vibration free. When the bearings are taken out of storage, they should be purged of the storage grease and filled with new grease.
