*Based on restaurant meals (BS 825-2)

**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.

Larger/intermediate sizes available, contact our team for more information.

Shaft Extensions

All SPEL Separator Systems have a large range of technical accessories to ease maintenance and monitoring.

Circular access shafts are supplied in 450, 600, 700, 900 and 1200mm diameter. Rectangular shafts are supplied in 800, 900 and 1000mm X 1000/1250/1500mm. GRP ladders can be incorporated for more access, complete with stainless steel fixings.

200/300 Series

Shafts can be laminated onto the tank up to a maximum height of 1.2m. Above this height extension shafts can be supplied separately for on-site fitting during installation.

400 Series

Shafts up to 400mm high are laminated onto the tank. Above this height extension shafts can be supplied separately for on-site fitting during installation.

500 Series

Shafts up to 300mm high are laminated onto the tank. Above this height extension shafts can be supplied separately for on-site fitting during installation.

600 Series

Stub access shafts are fitted 100mm high and extension access shafts fitted as 500 series. Above this height extension shafts can be supplied separately for on-site fitting during installation.

Extension Shafts

These are supplied in 500mm increments and are available in different laminate specs to suit site-specific invert levels and applications.

Guide Rails for Coalescers

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 unit lifting/locating/locking system for positive location and security locking

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.

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 here.
