SPEL Synthetic/Midel Oil Separators

The introduction of synthetic cooling oil in transformers has dramatically improved the fire safety record for grid-based substations, these oils are classified as K-class fluids with a high fire point of >300°C to IEC 61039.While the use of such a fluid reduces fire risk and associated costs, the difference in specific gravity (SG = 0.97 at 20°C) presents challenges for capturing this type of oil in a conventional separator in the event of an oil leak or spill. This has resulted in SPEL conducting extensive testing and redesign to ensure that Midel can be safely and reliably captured in the advanced SPEL Midel Separator.A further technical advance in the SPEL Midel Oil Separator is the inclusion of a motorised Automatic Closure Device (ACD) which will shut down in the event of a catastrophic spill.

For Midel Transformer Fluids

Introduction and operation

The SPEL Midel Oil Separator models are designed for high performance and long service life between maintenance periods.

The Midel range is a two chamber system for enhanced performance and reduced maintenance.

An alarm will sound and/or message an alarm on site or to a control room and automatically close off the separation chamber via the auto closing device, closed by a motorised valve. This is actuated by an oil alarm, closing the outlet in the case of a spillage emergency or when the maximum oil capacity has been reached.

Automatic Closure Device

The SPEL Midel Oil Separators have a closure device by way of a motorised valve actuated by an oil alarm. The alarm will sound and/or message an alarm on site or to a control room and automatically close off the separation chamber from the outlet in the case of a spillage emergency or when the maximum oil capacity has been reached.

Shell Design

Designed with reference to BS EN 13121. All tank shells carry the SPEL 25 Year Warranty and life expectancy in excess of 50 years.

Shell Specifications

Different tank shell specifications are available dependent upon tank invert levels, ground conditions and ground water levels. (See Installation Guidance section)

Inlet/Outlet Connections

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 coalescer unit is mounted in the second chamber, providing a coalescence process for the separation of smaller globules of light liquid pollutants before final discharge to the surface water drain.

Larger sizes available upon request*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.

Extension Access Shafts

SPEL Coalescer Guide Rail Systems

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 Lifting, Locating and Locking system (3L)

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.

Alarm Systems

Automatic Alarms/Monitoring Systems

Alarm systems are available for all SPEL separators. These include probes for oil, silt and high level. There are also a range of control panels including solar power, more detail on our alarm systems can be found in Section 8.

Control Panels

Alarm Probes

Tripod & Hoist

SPEL tripod and hoist

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.

SPEL Econoskim

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. For more information, click here.

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.
