160/225/300mm diameter PVCU socket/spigot.
450, 600, 750, 900 and 1200mm diameter GRP spigot available, for connecting to site pipework via Flex-Seal/Band-Seal or similar flexible couplings.
The nine inlet/outlet options below are available to assist with design and installation.
The purpose of the Automatic Closure Device (ACD) is to close the separator off automatically when the maximum capacity of light liquid/oil is reached.
The ACD ensures that in the event of a major spillage, pollutants do not pass into the drainage system; it should not be regarded as a substitute for an automatic alarm/monitoring system. The oil alarm and ACD are both required to comply with BS EN 858.
If the tank should fill with light liquid/oil the ACD, which is calibrated for a specific gravity of 0.85, will automatically sink and close off the SPEL Puraceptor®.
Normally routine maintenance would include removing light liquid intercepted within the Puraceptor®. If a SPEL automatic alarm/monitoring system is incorporated, it will automatically indicate when the Puraceptor® should be emptied. Only in an emergency will the Puraceptor® fill to its maximum and activate the ACD.
In such an event the Puraceptor® should be completely sucked out/emptied and the ACD lifted out.
Prior to installation the ACD retaining tube should be covered with polythene to prevent ingress of concrete etc., which would fall onto the ACD and cause a malfunction.
Dependent upon site conditions it is advisable to remove the ACD periodically taking care not to raise it too quickly and damage the plastic/copper float. Clean it from debris/silt to prevent premature closing. Check the seating in the base unit is free of debris/silt that could prevent proper closing in an emergency.

**SPEL Separators are designed for a maximum flow (NS/NSB) but can be fitted with larger than the recommended maximum connection size IN/OUT or with the addition of adapters providing the maximum flow (NS/NSB) cannot be exceeded or any increase in the operating level in the SPEL Separator to cause the captured pollutants to escape into the vent connections or through access shaft connections. Any overriding of the above criteria could jeopardise performance to the European Standard BS EN 858-1.
Note: Model FP1C/SC is a special Forecourt separator with 7600 litre spillage holding capacity. Click here for more information on Forecourt Separators.
Operation:
Flow enters the chamber from the inlet pipe, and the separation process begins as the flow moves towards the coalescer. Oil rises to the surface, silt settles out and the cleanest water then enters the coalescer which polishes the flow to a higher level prior to discharge.
The Puraceptor benefits from the unique SPEL coalescer which is the heart of all SPEL separation systems. The foam insert is located in a stainless steel basket and delivers high quality water, long life, and ease of maintenance.
The other key component is the fail safe Automatic Closure Device (ACD) which will shut the system down in the event of a catastrophic oil spill.
Operation:
The SPEL Two Chamber Separator is the result of long development with National Grid and has resulted in a system that can substantially reduce maintenance costs.
The Two Chamber unit has all the benefits of the Class 1 Puraceptor but the addition of a strategically located full height baffle wall protects the unique coalescer from the bulk of the silt load.
The coalescer is mounted in the second chamber (clean zone) where it is more effective as well as being protected. The result is that it will not clog as quickly and this can equate to longer periods between maintenance.
This is the SPEL Puraceptor two chamber model sizing chart. For the difference between single and two chamber models see the explanation below under operation.

Note: only applicable to units fitted with the SPEL Coalescer
Normal servicing of the smaller SPEL Separators frequently requires emptying the unit completely. Guide rails provide access for the coalescer units to be taken out, cleaned and returned and guided accurately to their seating positions. However larger SPEL Separators may only require the hydrocarbon pollutants and silt to be removed.
In order to limit the servicing to sucking off the fuel/oil from the top and the silt from the bottom guide rails are required to ensure coalescer units are replaced into their correct positions.
The system is robust, manufactured throughout in stainless steel and the action positive, leaving no doubt the coalescer unit is located properly.
Brackets fixed to the top and bottom of the coalescer unit simply engage the stainless steel guide rail fixed to the top of the stub access shaft. The coalescer is then lowered in the normal way, being guided at the correct angle into the conical base unit which locates the coalescer unit into its final position.
Extension guide rails can be incorporated into SPEL extension shafts to suit (preferably when ordered with the separator).
SPEL coalescer units lowered into the separator with the SPEL guide rail system are easily guided into the base unit’s conical moulding to automatically sit correctly.
However, when the separator is full of water, debris or silt accumulated over a period, this could prevent the coalescer unit from re-seating correctly after servicing.
The coalescer unit lifting/locating/locking system provides assurance the coalescer unit is seated correctly and can be locked into position to prevent tampering.
The system is particularly suitable in SPEL Separator + Econoskim® systems where the total contents of the separator are not emptied on servicing.
The system comprises a robust stainless steel lifting and lowering handle that locates on the guide rail system. When the coalescer unit is correctly located in the conical seating in the separator, the handle will align with guide rail top bracket i.e.. the handles slotted holes with the top bracket clip locking groove, see diagram.
When aligned the stainless steel clip can be located through the slots and lock into position on the top bracket.
The stainless steel lifting handle can be extended to suit deep tank inverts and provide easy access for lifting manually or with the SPEL tripod and hoist.
For silt, oil and high level detection, compatible with the below alarm probes.
Available with optional flashing beacon, and GMS/ SMS communication, also compatible with the below alarm probes.
Dedicated alarm system for the full range of SPEL Grease Separators.
Detects oil and indicates when the treatment system’s oil storage is full.This probe is required in order for a treatment device to comply with BS EN 858.
Monitors the silt layer in the treatment system and indicates when the silt layer has reached its maximum level.
Indicates when the liquid level in the treatment system rises excessively e.g. in an outlet blockage situation.
Where surface water run-off has a high silt content the coalescer units can become filled, making them heavy to lift out. In order to facilitate easy withdrawal of coalescer units the SPEL tripod and hoist is recommended.
The SPEL Separator + Econoskim System is a patented system designed to maintain oil separators at peak performance for as long as possible. It does this by skimming the oil from the surface of the separator and transferring it to a separate containment tank for simple collection by a waste oil contractor thus reducing costs and further protecting the environment.

1. When the SPEL constant monitoring system detects the level of fuel/oil pollutants has reached the pre-determined volume, the skimmers are brought into operation, transferring these pollutants from the SPEL separator to the SPEL Tankstor® containment tank. When the transference of light liquid pollutants has been completed, the system automatically stops the skimming process and re-sets.
2. During the skimming cycle a small amount of water is transferred from the SPEL separator into the SPEL Tankstor® containment tank. In order to maximise the capacity of the SPEL Tankstor® containment tank for pollutants, accumulated water is automatically transferred back to the SPEL separator.
3. The process repeats automatically every time pollutants reach the pre-determined volume. When the SPEL Tankstor® containment tank is 90% full, the SPEL constant monitoring system signals ‘EMPTY NOW’ with an audible and visual alarm.
