Do you need other options?  Here is a short list of some of the most popular choices:

1. Solar Oil Skimming System
   The solar oil skimming option is ideal for locations that do not have access or have limited access to electricity. A 12V DC motor runs off a deep cycle battery that is recharged by the solar panel. Various 12V accessories are available as well.
2. Transfer Package and Underground Oil Skimming System
   

   This option is for applications in which the oil storage tank is far from the point of oil removal or for below ground applications. This turnkey system consists of a small collection tank, a pump, small control panel and three float switches. The oil that the oil skimmer picks up is deposited to the collection tank. When the collection tank is full, the middle float switch signals the pump to turn on. The oil is then pumped to your storage tank or facility for permanent removal or storage.

3. Controls/Accessories
   Abanaki offers a float switch and warning light combination to monitor fluid level in the skimmed oil collection drum, which helps prevent overflow. Other electrical options include timers, heaters, and control panesl. Abanaki also offers poly shelters and discreet secure enclosures as well as a variety of mounting options for the oil skimmer.
4. Concentrators
   Abanaki Oil Concentrators® provide a secondary separation step after oil skimming to virtually eliminate water from skimmed product. Units are available for easy installation on most Abanaki oil skimmers.

5. Specialized mounting arrangements
   The Oil Grabbers have a variety of mounting arrangements design to make setup in even the most demanding applications a breeze.  These include floor mounts, wall mounts, flat mounts, channel mounts, guard rail mounts and boom mounts. 

We love a challenge, so if you need something not mentioned let us know and we will do our level best to give you a great solution.

Choosing an oil skimmer best suited for your application will maximize oil removal while minimizing initial outlay and oil skimming operation costs.

How much skimmer capacity do you need? 

Capacity should be based on the maximum amount of oil to be removed within the shortest available time. For instance, total oil influx may be 200 gallons in a 24-hour period, which averages about 8.3 gallons per hour. But if most of it comes during a single eight-hour plant shift, you will probably need a removal rate that is three times as high, especially if you are trying to prevent an unwanted discharge of contaminated water to a sewer system. As a rule-of-thumb, specify approximately twice the maximum capacity you anticipate needing for normal conditions.

What do the capacity ratings mean?
Oil skimmers usually have an oil removal rate expressed in gallons per hour. The rate varies with oil viscosity, so Abanaki rates skimmers using SAE 30 weight motor oil at 65°F (18°C). It is very important to ask the manufacturer what they are basing their capacities on and get an exact SAE weight or viscosity.  Beware of generalities like ‘a medium-weight oil.’

Will there be water in the skimmed oil?
All oil skimmers pick up some water with the oil they remove. Some designs, particularly suction skimmers, pick up more water than others. High water content increases oil recycling and disposal costs. Generally, the ratio of water-to-oil decreases with thicker films of floating oil and slower moving pick-up media. An Oil Concentrator® or decanter installed at the oil skimmer discharge port provides secondary oil/ water separation that can reduce water content to nearly zero.

How much oil will be left in the tank?
An oil skimmer continues to remove oils as long as there are oils present. Depending on oil influx rate and the oil skimmer's removal rate, residual oil in the water may be as low as a few parts per million. When residual oil reaches this level and further reduction is required, it may be more practical to use a secondary removal method following skimming, such as membrane filtration.

What do I sacrifice if I choose a portable oil skimmer?
Oil skimmer portability is a plus in some applications. For example, in plants, mobile equipment service shops, and at remediation sites, a portable oil skimmer can sometimes service multiple machines, sumps, or wells. Portable units usually have a lower removal capacity than stationary units.  Also, when you move an oil skimmer it can be dripping water or oil when you remove it, so having a few rags on hand is a good idea.

Choosing an oil skimmer best suited for your application will maximize oil removal while minimizing capital and operational costs. The impoundment capacity, shape, and location of a tank and water impoundment are major factors in choosing the right oil skimmer to lower your costs.

1. Size/Design:
   It is critical that oil in the water is given the opportunity to separate. Oil and water can emulsify when subjected to turbulence and other mechanical agitation. Avoid this by having water return to the tank below the liquid surface at as low a velocity as practical. Make sure your tank or sump provides quiet areas, weirs, and sufficient volume to allow adequate time for oil/water separation.
   
2. Shape:
   Tanks without nooks and crannies for oil to get stuck in are best. If you have an irregular shape, put the oil skimmer where the largest amount of oil accumulates. Consider a means of directing oil towards the oil skimmer such as a floating boom or baffle plate.
3. Location/Installation:
   The physical location and characteristics of the tank and collection container are important and it is vital to ask the right questions such as:
   • Does skimmed oil need to be pumped from the oil skimmer to the container?
   • Will oil skimmer access for periodic maintenance be a problem?
   • How much mounting space is available?
   • Are tank or container modifications required?

Fact:

Oil skimming makes use of the differences in specific gravity and surface tension between oil and water. These physical characteristics allow the belt to attract grease, oil, and other hydrocarbon liquids from the far side of the tank.

Oil Skimming Tip:

When selecting an oil skimmer, be sure to place the skimmer where oil is already gathering.  This will ensure the quickest removal of the oil.

Fact:

Belt oil skimmers and oil skimming will collect all types of oil including all free-floating oils, LNAPLS, DNAPLS, and some emulsified oils. The various belt materials  allow for any type of hydrocarbon removal.

Oil Skimming Tip:

There are several things to consider when choosing a belt for your oil skimmer. For example, some plastics won’t stand up to heat or strong chemicals, some metal belts won’t skim well from coolants due to rust inhibitors being present and certain plastic belts don’t last in heated applications. It is very important to choose a good oil skimmer vendor that offers a wide variety of belts to handle any situation.   Equally important is to inform them of the details of your application so they can provide assistance in choosing the proper belt material at the start.

Recently, a US automotive parts engineering facility contacted Abanaki Corporation about two issues it was having at its plant.

1. Wanting to reduce the high costs of constantly needing to replace its coolant due to oil contamination
2. Removing the oil from the wastewater recovery trenches.

The Tote-It machine center skimmer was the answer. The skimmer is well suited for parts washing and machining center applications. By removing surface oil from a wash tank, the parts will not be recontaminated as they are withdrawn. Furthermore, by removing tramp oil from a coolant tank, the company prevents excessive smoke and fumes that are caused by oil burning during cutting operations. The Tote-it also reduces bacteria growth in the tank, along with the resulting odor.

Once the facility utilized the Tote-It skimmer in both the cooling tanks and the recovery tanks, it was able to successfully remove the oil from the coolant and from the wastewater.Additionally, with the ability to clean the oil laden coolant, the facility was able to save a significant amount of money and time on coolant disposal costs.

Tramp oil is huge problem for machining centers.  It can affect the appearance of the finished part, lead to worker skin conditions and leave a haze of smoke in the shop creating an environmental hazard.  Many machining centers built today have limited access to the coolant sumps more than they used to.  This creates a dilemma: how do you remove oil from a coolant sump when you barely have access to it? A mini tube skimmer, like the Abanaki’s Tubetastic!®, may be the perfect solution for this problem. The Tubetastic! has an oleophilic tube that snakes into your machining center and removes the oil from the surface of your coolant.  It attaches to the side of the tank lip or it can enter through a slot in the side of the machine.   Furthermore, it has a high capacity to remove oil.  The Tubetastic! can remove as much as 1.5 gph of oil from the surface of cutting fluid, enough to handle virtually any tramp oil problem.

The TubeTastic! features a 50/60hz fan-cooled, continuous duty motor in either 110 or 220v and standard collector tubes allowing reaches of 8″, 12″, 18″ or 24″ with longer lengths available.

Sometimes there are situations where your oil skimmer will collect water. If you are running your skimmer 24/7 and the tank or pit runs out of oil, your skimmer will pick up whatever is remaing in the tank, and most of the time that will be water or coolant. There is a way to prevent this and that is by utilizing an oil water sperator/concentrator in conjuction with your oil skimmer. The oil water conentrator attaches to the skimmer and helps in further separating the water/coolant from your oil. This unit is placed on the back of the skimmer. The skimmed material is drained into the concentrator and then it separates the water from oil. You can then drain the water back into the tank or well through one hose, and the oil drains from another. So, next time you’re wondering how to increase the efficiency of your oil skimmer, take a look at the oil water concentrator to help solve your dilemma.

The Oil Concentrator is non-electrical and contains no moving parts — it simply receives liquid directly from the skimmer. Based on the principle of gravity separation, the Concentrator tank is sized so that there is adequate dwell time for the oil and water to separate. Water discharge is through a tube that has an open end near the bottom of the Concentrator, while oil flow is through a separate drain port near the top. As additional liquid enters the Concentrator, water and oil are
forced out through their respective discharge tubes and ports.

Abanaki Corporation, the world leader in oil skimming technologies, announces the addition of the Oil Boss® Oil Skimmer to its extensive coolant maintenance product line. The Oil Boss solves problems that have plagued regular skimmers in machine shops.

Under most operating conditions, Abanaki’s TubeTastic! picks up oil with only small traces of water or coolant. However, as surface oil is reduced to a thin layer (1/16 inch thick or less), more water (or coolant) may be picked up along with the oil. When used in tandem with the TubeTastic, the Oil Concentrator solves this problem by providing final phase separation. The result is water (or coolant) available for recycling, and virtually water-free oil for disposal.
