Used Power Packs

Considering a used Power Pack? Here's how to reduce risk.

Used reefer gensets, known as power packs, can offer refrigerated container operators both large and small an inexpensive way to expand their operation and increase refrigerated container throughput. Lower initial investment costs of used power packs also reduces financial barriers, allowing start-up operations the flexibility to gain entry into the reefer market.

Yet, buying anything used is risky. Knowing what to look for is key.

Understand your needs first.

Since the supply of preowned power packs may be limited, there’s a tendency to purchase the first one that comes along, usually the one that first appears to be in good condition. But it’s very important that the power pack you choose fits your needs correctly. A generator that is too large – having a kW rating that’s higher than your expected load - can be almost as bad as having one that’s too small for your needs. Our article on wet-stacking highlights this.

If your operation will need to power 20, 30, or 40+ reefer containers, then be sure your power pack is sized to meet at least 70% of that number consistently. In this way, you will not risk unexpected generator shut-down due to overloading and your connected load will be sufficient enough to avoid problems associated with wet-stacking.

Be realistic

Good or bad, used power packs will have a history to them. It's fair to assume that before being replaced most power packs are typically used right up to the point of near failure; until the very last bit of productivity is squeezed from their essence.

What remains is a worn-out engine that’s unable to maintain horsepower, a generator with windings that are nearly torn from the stator and unable to produce electrical current safely, a rotten container that’s rusted through, broken and unusable receptacles, plus many other failings. With thousands of dollars in perishable cargo at stake, used machines are hardly something that can be purchased AS-IS and be expected to provide quality power generation. This is the risk.

Even if the used power pack that you are considering is not nearly as bad as the one pointed out in this example, it is safe to say that purchasing a used machine will offer limited life expectancy and require some sort of additional investment. Major failures can happen at any time creating huge and unexpected repair bills with potentially long power pack downtime – what’s that worth?

These costs are real and need to be figured into the overall operating expenses of purchasing and owning a used power pack with questionable history and limited records availability.

A better solution,
One that won’t leave you stranded like an old, worn-out power pack might.

Allow Power Pool Plus to provide the right used power pack for you. Our experienced team will identify the right generator package that’s properly sized to meet your requirements. Because finding one that’s sized correctly for your needs may not always be easy.

Through our comprehensive inspection process and in-depth operational evaluations, Power Pool Plus offers peace-of-mind on every used generator package purchased through us.

Here’s how we do it

Once a used generator passes our initial operational analysis, it goes through a process that we call re-qualification.
The engine and generator are the core components of any refrigerated container power pack. So our re-qualification process focuses on documented and historical failure facts based on each make and model genset. And with 30 years’ experience there is quite a bit of history to lean on.

Our intent is to extend the service life of a known low hour engine or generator set at a cost savings to our customers – often times as much as half the cost of purchasing new.

Understanding that the negative effects of fuels, oils, coolants, water, UV rays, age, and dry rot are the #1 enemies of power units, we go through an exhaustive process on any used machine that we evaluate. Key engine and generator parts are evaluated and replaced as necessary to ensure a product that is capable of handling the demands of typical power pack operations.

Other components like the shipping container enclosure, fuel tank, receptacle panels, and controls are reconditioned or replaced as needed.

The end result will allow your operation to be successful through owning a used reefer power pack with the assurances of professional inspection and re-qualification provided at a significantly reduced cost over a new machine.

While it’s difficult to eliminate all risk when purchasing used gear, our team reduces the chances of failure significantly and provides our customers with equipment that will offer productive output while maximizing your operation’s profitability for years to come. And isn’t that why you’re looking for a power pack in the first place?

Don’t take the risk on your own. Trust Power Pool Plus to deliver results and savings.

*Remember to properly maintain your equipment according to manufacturer’s recommendations to ensure long operational life with minimal downtime.

4 Conversation Starters to Creating a Custom Power Pack

A power pack that fits exactly into your unique work environment can help maximize workflow efficiencies and help your team save both time and money.

What if you had a customized power pack that was designed around your operation and the challenges which you face daily?

Typical designs can feature 30, 40, or 50 or more receptacles all placed in one location on the power pack enclosure. Yet, unique yard layouts, stacking limitations due to container handling equipment, and other defining factors create challenges in trying to position all your reefer Power Pack In Use around Reefer Stackstacks around a single power source. These challenges disrupt operations creating extra labor time.

But it doesn’t have to be this way.

And it all begins with having a complete understanding of what the operator is looking to accomplish.

4 questions that help get the conversation started might be.

1) How many plugs (or reefer cord connections) will be needed?

  • Power packs that operate with too many unused plugs on a regular basis operate inefficiently and can create engine problems due to wet-stacking.
  • Having the right amount of receptacles that maintain a level of capacity near 75% is ideal for engine health and fuel efficiency.

2) Where will the reefer stacks be positioned in relation to the intended power pack placement?

  • Too tight and critical airflow might be affected. Creative thought on power pack design can address this.
  • Too far away and reaching the power pack may be challenging. Bringing the receptacles to the reefer stacks through the use of remote trees may be needed.

3) What is the expected run-time between fuel deliveries?

  • Sizing the fuel tank appropriately to this key factor can be the difference that allows an operator to run non-stop between deliveries.

4) What is the operating climate?

  • Certain elements of design can help mitigate the negative effects of either tropical heat and humidity or artic cold.

How load affects Power Pack performance

Proper Loading of Power Pack Reefer Generators

Are your reefer loading processes harming your power packs?

In a recent survey we asked the question, ‘What is your typical practice for connecting reefer plugs to your power pack?’ Possible choices included:

  1. We fill the receptacle panel then start the power pack.
  2. We connect one at a time while the power pack is running.
  3. We connect them in groups of 5 or more at a time.

While the number of responses varied between the choices, a significant number selected choice #1, indicating that loading the power pack’s receptacle panel with connections prior to generator start is the preferred choice.

It’s easy to understand, perishable cargo tends to move in large quantities. And with many reefers hitting the docks at any one time, the goal, of course, is to quickly get these refrigerated containers connected to power. But take a moment to consider that this technique may have the potential to cause damage to your equipment which could potentially render your cargo without any electrical power.

Why this is bad.
Loading too many reefer boxes at one time on a power pack can cause the engine to work excessively hard to catch up to the required load. In the meantime, this may result in a drop in generator performance as the engine struggles to maintain sufficient power to meet this sudden demand. The results will be a reduction in hertz or electrical frequency causing potential damage to the generator’s voltage regulator. Loss of frequency can flow downstream to the reefer causing damage to refrigeration compressors. Additionally, there is added stress on the fuel delivery system to maintain engine power.

Either of these scenarios will leave you with a down machine, expensive repairs, and a load of perishable cargo without electrical power to maintain temperature.

How to avoid a problem
A systematic approach to loading Power Packs should be incorporated in order to avoid costly and time delaying damage.

Power Pack Loading Procedure, a Best Practice Approach
Every power pack is different and may have varying engine and generator configurations. It is strongly advised to review and understand all of the manufacturer’s operations manuals prior to beginning any power pack starting procedure.

Once started, here are some guidelines to ensure that you maintain the best performance from your power pack generator.

Applying load
Once power pack is properly started allow the engine to warm up for 5 minutes before loading reefers. Engage Main Breaker to ON Position.
For ESL Power receptacle panels:

  1. Insert a single reefer plug into the panel and secure locking ring by rotating clockwise
  2. Depress the plunger to energize receptacle.
  3. Repeat steps 1 and 2 above for each additional receptacle plug added to the panel.

Continue loading reefers until reaching a load of 50%. At this time, check amperage on the generator control panel. This is important to ensure that your generator is managing the load and working within optimal engine performance. Refer to the specifications of your power pack for total amperage information.

If at 50% capacity total amperage is under the specified maximum amperage of your power pack, then continue to load reefers gradually to full capacity, but continue to monitor the ammeter.

If amperage is OVER the maximum amperage STOP LOADING and wait for refrigerated container compressors to cycle before continuing to load more.

Loading too many reefers, especially hot reefers, at any one time may cause the amperage draw to exceed the limitations of your power pack.

Maximum amperages vary depending on the specifications of your power pack. If you are unclear on the maximum amps for your power pack, contact Power Pool Plus for information. Operating a power pack at near max amp rating should be monitored closely to avoid tripping main circuit breaker and losing all connected reefers.

A special note on loading: At minimum, there should always be at least a load of 25% of total panel capacity. In other words, if operating a 40 plug power pack, minimum load will be 10 reefers or 8 for a 30 plug machine. This will protect your power pack in 2 ways:

  1. Avoid the damaging effects of wetstacking – thick black exhaust smoke.
  2. Allow a more efficient use of your power pack. More reefers attached to your power pack means less fuel burn per reefer – which will save you money.

Unexpected shut down while connected to full load of reefers
Should an unexpected engine shut down occur, either through a run-fault event or manual stop, never perform a re-start while connect to a full load of refrigerated containers. Instead, load should be removed from the power pack and brought back on gradually. Best practice would be; de-energize ALL ESL receptacles, ensure that the main breaker is CLOSED, and re-start the power pack. At this time bring reefers back on line following the procedure highlighted above by energizing the ESL receptacles individually until all are successfully back online.

Manually shutting down an operating Power Pack
Often times, out of convenience, bad habits, or simply insufficient operator instruction, emergency stop (E-stop) buttons are routinely used to shut down a running power pack.

Emergency stop buttons should only be used for emergency situations, such as pending harm to personnel or equipment.
Using E-stop buttons as a regular means of power pack shut down can cause damage to the engine and generator components by not allowing a proper disconnection of electrical current to the load and necessary slow cool down of the engine.

Instead, follow this procedure,

  1. Open main generator circuit breaker
  2. Allow engine to cool down for 10 minutes
  3. Press the stop button located on the generator control panel. The generator will then stop. Some power packs have a built in shut down procedure that initiates upon pressing the stop button on the Control Panel. Check your Owner’s manual for specific information on your power pack design characteristics.

In short, unless it is an actual emergency, use the stop button located on the Control Panel and NOT the Emergency Stop buttons.

Wrapping it up
Each Power Pack is different with unique engine kVA and kW output. But the process for loading them to protect the Power Pack from overloading is the same. Following these quick and easy steps will ensure long lasting performance from your reefer power solution.

Power Pack maintenance doesn’t begin and end with oil changes. It starts with proper machine operation. No matter if your operation handles chilled loads, frozen loads, or pre-trips hot reefer boxes, Power Pack performance can be greatly affected by the way in which load is applied. Following these procedures to ensure that you get the most out of your reefer power system.
