Harlequin Oil Tanks are suitable only for the storage of:
All Harlequin Oil Tanks must be installed in accordance with supplied instructions, the requirements of OFTEC Technical Instruction Book 3 and prevailing statutory requirements. Please note that Harlequin Heating Oil Tanks are not suitable for connection to a fuel delivery system incorporating a flexible hose and automatic trigger nozzle.
A bunded oil tank simply consists of a tank within a tank. The fuel is stored in the inner tank and the outer tank acts as a failsafe so that in the event of a spillage, excess fuel will collect in the outer tank - thus averting a pollution incident.
Bunded Oil Tanks have been proven to significantly reduce the risk of pollution at oil storage installations. They are a requirement at commercial, industrial, institutional and commercial premises; all installations in the Channel Islands; and, at most domestic installations in the United Kingdom and Republic of Ireland.
Single skin tanks on the other hand, consist of only one shell or skin. This means that in the event of a tank split, valuabe heating oil will be lost and the surrounding environment will be polluted by the heating oil contained within it.
Top outlet bunded oil tanks are quite simply oil tanks which have the outlet to the burner placed at the top, rather than the bottom of the tank. Oil is then drawn out, as opposed to being gravity fed through the outlet at the bottom. All Harlequin Bunded Oil Tank models can be provided as either top outlet (ITT) or bottom outlet (ITE) tanks.
Top outlet tanks are suitable for use with most pressure jet burners - we recommend to install a Tiger Loop de-aerator, to eliminate the need for a return line to the tank. Pressure jet burners are fitted to most oil boilers sold today in the British Isles.
Top Outlet Bunded Oil Tanks are not compatible with vapourising (or wick) burners, fitted to some oil fired stoves. At such installations, a bottom outlet bunded oil tank should be fitted or else an oil lift device should be incorporated within the oil supply line.
If you are in any doubt as to the compatibility of top outlet or bottom outlet bunded tanks, consult the appliance manufacturer or OFTEC.
If the tank is less than 3500 litres in capacity, it should not be placed within 760mm of a combustible boundary e.g. a fence.
This distance assumes that there are no flu outlets or buildings between the tank and the boundary. Where these clearances cannot be achieved, the protection measures noted in British Standard BS 5410: Part 1: 1997 must be provided, by means of a 30 minutes fire-resistant wall - which extends at least 300mm above and beyond the ends of the tank.
For tanks with a capacity greater than 3500 litres of for fire barrier construction requirements, please contact OFTEC for advice.
Oil Tanks with a capacity of less than 3,500 litres should not be placed within 1.8 metres of a flu outlet.
Where these clearances cannot be achieved, the protection measures noted in British Standard BS 5410: Part 1: 1997 must be provided by means of a 30 minutes fire-resistant wall which extends at least 300mm above and beyond the ends of the tank.
For oil tanks with a capacity over 3,500 litres or advice on constructing a fire resistant barrier, please contact OFTEC.
Oil Tanks with a capacity not greater 3,500 litres should not be fitted any closer than 1.8 metres to non-fire rated (30 mins. minimum) walls or eaves.
It will be necessary to protect exposed eaves forming part of a roof within 1.8 metres of the top of an oil storage tank to provide a 30 minute resistance to fire. Cladding can be applied to the eaves in order to prevent fire spreading to the roof.
If the tank capacity is greater than 3500 litres or you require further advice, please contact OFTEC.
Oil tanks should always be installed by a trained technician, preferably an OFTEC approved tank installer. Harlequin can recommend a tank installer for you, as part of its 'Tankmark' scheme. Tankmark is a network of approved tank installers. You can find your nearest installer by simply visiting the tankmark website and using your postcode to search your area.
As a minimum, all plastic oil tanks should be installed on a flat, level, fire resistant surface, capable of supporting the weight of the tank when fully laden. Where concrete slabs are used, they should be at least 50mm thick.
The base should extend at least 300mm beyond the widest points of the oil tank and fully support the base of the oil tank in its entirety. Piers are not suitable for this purpose and will cause irreparable damage to the oil tank, resulting in premature failure and catstrophic product loss.
Detailed oil tank base requirements can be found within OFTEC Technical Instruction Book 3.

Water will form in any oil storage tank. It is perfectly normal and occurs as a result of the tank warming up during the day and then cooling at night. In single skin oil tanks it will collect in the base of the tank; in bunded oil tanks it may additionally collect between the inner and outer tanks.
All oil tanks should be inspected annually for the presence of water found to be present either inside the oil tank or in the case of bunded oil tanks, between the inner and outer tank. Failure to remove any condensate may result in fuel contamination and irreparable product damage.
Condensate can be removed by most oil tank installers, technicians and most fuel distributors. For details of your local manufacturer approved, OFTEC certified tank installer, vist Tankmark.
No. Harlequin Waste Oil Tanks are only suitable for the storage and disposal of industrial waste oil. To dispose of petrol or any other flammable liquid, please contact your local environmental authority.
As AdBlue is very sensitive to contamination, it is important that it is stored in a containment system which can protect it from contamination threats and which can maintain the AdBlue at an optimal condition.
The de-ionised elements of AdBlue can draw ions from the materials in which it is stored. This can change the chemical composition of the AdBlue and causes salts to form which in turn clog the ceramic head on the SCR.
A common cause of premature SCR failures is the incorrect material selection in AdBlue Storage. Inert materials should always be used to handle AdBlue.
Harlequin AdBlue storage and dispensing tanks have been designed specifically for the safe and secure storage of AdBlue. In addition, all Harlequin AdBlue dispensing equipment has been selected in order to protect both the AdBlue solution and the equipment itself.
AdBlue is a trade name for AUS32 (Aqueous Urea Solution 32.5%). It is injected into the exhaust gases of modern diesel engines as a post combustion process. Its purpose is to reduce the percentage of harmful NOx (Nitrous Oxides) present in the vehicles emissions.
The reaction takes place in a special piece of equipment called an SCR. The requirements to reduce vehicles harmful emissions (pollutants) are specified in European legislation, namely Euro 4, 5 and 6.
In order to reach the reduced levels of pollutants as defined within current and future European legislation, vehicle manufacturers need to call on one of two types of technology: either SCR (Selective Catalytic Reduction) or EGR (Exhaust Gas Recirculation).
This permits the tank to be connected to the SecuTech LRC Overfill Prevention System, used by an increasing number of fuel distributors - and is not for consumer use.
When connected to the SecuTech LRC Handheld Unit it affords failsafe overfill protection to your installation and is a safer and more reliable alternative to old fashioned, mechanical overfill prevention valves.
As a minimum, all tanks should be installed on a flat, level, fire resistant surface, capable of supporting the weight of the tank when fully laden. Where concrete slabs are used, they should be at least 50mm thick.
The base should extend at least 300mm beyond the widest points of the tank and fully support the base of the tank in its entirety. Piers are not suitable for this purpose and will cause irreparable damage to the tank.

Please note that BioDiesel is inherently unsuitable for storage in tanks manufactured from traditional heating oil and diesel polymer grades.
