Suparator oil separators

The most efficient oil separator

  • Very short payback time
  • Maximal cleaner durability
  • Optimal quality of manufactured items
  • Maintenance free construction
  • Minimal operating costs
  • Also effective for smaller installations
  • Several capacities available

The most efficient oil separator

Cleaning- and degreasing baths are widely used in an industrial environment. Good cleaning is of fundamental importance for the quality of manufactured items. The degreasing capacity of hte cleaning agent is gradually decreasing in proportion to the amounts of oil and other pollutants, such as dust and grinding remainders, get mixed into the cleaning agent. Good oil separation equipment is therefore crucial.

Independent research has shown [1] : Suparator® is without doubt the most efficient oil separator avalable in the market. Oil is separated from the cleaning agent within minutes. It will no longer be the oils and greases that will urge you to replace the cleaning agent..

Almost all big car manufacturers are using Suparator®

Also effective for smaller installations

The smart design of the Suparator® unit, together with the patented Suparskim® skimmer, allows to remove even small quantities of oily substances out of a washing unit or degreasing bath. The increasing waste processing cost are making oil separation cost-effective also for smaller cleaning units. This is the reason why Suparator® is introduced in many different industries. Also for waste water treatment and drilling coolant emulsions.

The Suparator® can generate profit for smaller installations, starting from 200 litres

Maximum cleaner lifetime

Maximum cleaner lifetime. An aqueous cleaner is not particularly expensive but the associated costs, however, can be substantial. For instance the costs involved in emptying a bath, cleaning and re-filling it and heating up again. The biggest cost factors however, are the disposal of the spent cleaner and the cost of poor product quality and rework. The Suparator® keeps the cleaner free of oil; that means trouble free cleaning for a much longer period of time.

The Suparator® extends the life of your cleaner 4-10 times over

Optimal product quality

Suparator® systems and solutions differ in a number of essential ways from any other, conventional, separator. For instance the patented Suparskim® skimmer, which automatically adjusts to the level in the bath. Due to its unique construction, the top layer in the bath is quickly transferred into the Suparator® unit where the oil is removed from the cleaner in a matter of minutes. This is important because, inside conventional separators, the oil accumulates on top of the cleaner over a long period of time. This will give entrapped dirt, like dust and grinding residue, ample time to separate from the oil and re-enter the aqueous phase. Oil and dirt accumulate in the bath, causing cleaner performance to drop and resulting in unclean products. Only the Suparator ® maintains the cleaner effectively enough, by separating the oil before dirt settles out keeping the oil concentration in the cleaner low all the time, no matter how long you use it. See the pictures on the right : the left sample was taken right after separation, the right sample from the same solution is showing the liquid two months later.

Maximum cleaner lifetime

Cleaner performance degrades over time, due to pollution. Without oil separation (red line) the effect is noticeable very quickly, making an early bath dump necessary. Skimmers, conventional oil separators or coalescers (orange line) improve matters but nothing more. The Suparator® (green line) eliminates oil as the cause for bath changes.

Very short payback time

The Suparator® requires a slightly higher investment but pays back faster by providing improved product quality, extended cleaner lifetime, and lower costs. As a result, the Suparator® on average has a payback time of one year, often shorter than that. In the mean time you benefit from a cleaner process and because the Suparator® is maintenance free, it soon pays for itself.

Even with small amounts of oil, the initial cost for the Suparator® is soon recovered

Maintenance free construction

The heart of a Suparator® unit is a passive construction without any moving parts. Since the Suparator® does not use a filter or membrane, it is truly maintenance free. Cleaning only needs to be done occasionally; as the oil is separated quickly, dirt does not get a chance to sediment inside the unit. For applications with very high pollution levels, simple, automatic flush provisions are available which practically eliminate the need for cleaning.

Save on maintenance with the Suparator®

A range of capacities

Suparator® units are available in a range of capacities. The variety of different models and options to choose from, make it possible to tailor a Suparator® system to match any manufacturing process. The Suparator® is now used for cleaning baths from 200 up to 400.000 litres !

From large to small there is always a suitable Suparator®

How is the Suparator® used?

The Suparator® is the only oil separator that keeps the oil concentration in the cleaner low at all times. How does it work?

1. It starts with a Suparskim® skimmer which is mounted in the bath or tank and which follows the liquid level. The skimmer is designed to skim off the top layer continuously, inhibiting the formation of a floating layer.
2. The top layer, cleaner with traces of oil, is transferred into the Suparator® unit using special, non-emulsifying pumps which prevent mixing of the oil.
3. Inside the Suparator® unit a laminar flow is generated. With an ingenious construction of valves and plates, the oil is collected, accumulated and concentrated in a number of consecutive steps (see “The four step Suparator® principle” previous page). The clean fluid is discharged via the bottom section of the unit. The oil, with the dirt in it, is separated; without any cleaner.
4. The clean fluid is returned to the bath under gravity or by means of a pump, ready to be used again.
