ENERGY EFFICIENCYWith everyone’s attention focussed

on global warming and carbon foot

prints, Cormac’s drive towards constant

improvement and development has resulted

in a new generation of energy-effi cient

vertical tanks for use with most bitumen

based products. Our Cortherm™ system

uses a combination of traditional insulation

materials, combined with a special refl ective

thermal coating, which together produce

spectacular energy savings compared

SAFETYWorking in conjunction with the UK’s

leading level measuring specialists we

have developed our RBA compliant safety

system to prevent overfi lling and spillages.

The safety control equipment incorporates

a special bitumen TDR guided radar

continuous tank level measuring system

and an independent high level alarm

probe. Measuring levels in bitumen tanks is

particularly diffi cult: the hot vapour rapidly

coats everything in the tank with bitumen,

rendering some level systems inaccurate or

ineffective, sometimes in a matter of days.

By contrast the Cormac TDR system has

an impressive track record in bitumen level

measuring and continues to give reliable

results even when the stainless steel

conductor cable becomes coated.

The system uses data from the TDR sensor

to provide an early warning high level

alarm (HLA) set at 90% of the available

tank contents, whilst an independent

ultimate high level alarm is set 2.5% higher,

providing a ‘belt and braces’ warning

should anything fail or affect the reading

from the TDR.

with conventionally clad tank designs.

Independent tests carried out on one of our

100 m3 tanks have shown that users can

benefi t from an annual energy saving of over

40000 kWh! To reduce energy consumption

even further, our tanks are fi tted with

proprietary progressive multistage heating

systems, which maintain the temperature

of bitumen within 1.5˚C of your required set

point. This winning combination offers the

unbeatable performance demanded by our

clients and we are confi dent that the new

tanks will pay for themselves twice over

during their lifetime.

The control panel clearly displays the

current bitumen level in the tank, the total

available space left in the tank (ullage) and

the current bitumen temperature, taking into

account the RBA recommendations that

there must always be 10% of the available

tank level kept empty.

A simple unambiguous traffi c light system,

which uses multi LED technology for bulb

redundancy and increased brightness,

clearly shows the tanker drivers the status

of each tank. A green light means the

complete tanker can be safely discharged,

whilst amber or red lights indicate either

the HLA or ultimate high level alarm has

been initiated. If for any untoward reasons

the early high level alarm is reached during

the fi lling process, an amber beacon at the

control panel and the amber traffi c light

fl ash together with an audible warning,

giving suffi cient time to shut down the

fi ll and safely blow the tanker lines clear.

However even if this fails, the independent

high level probe alarm will still provide

ample warning to prevent overfi lling.

MOBILE TANKSCormac’s range of trailer mounted mobile

tanks has been developed to meet the

demand of the asphalt manufacturing

industry where short term contracts in

different locations are necessary. The

tanks are designed for moving in the

empty condition and have a jacking leg

system to support the fully loaded tank

on site. Capacity ranges from a 20 m3 litre

unit capable of taking a full tanker load of

BITUMEN TANKS

material to larger capacity units to meet

the production requirements of our clients.

We build the complete units based around

proprietary tried and tested axle units.

Heating of the tanks can be carried out by

direct oil fi ring or electrically, either from

an external power source or self-contained

generator mounted on the trailer. Operation

of the heating, pump discharge system

and RBA compliant level control cum alarm

system is all carried out by the onboard

control panel, conveniently situated at the

rear of the trailer. The bitumen pump is

incorporated in the trailer with the discharge

pipe work providing either an automated or

manual plant feed.

SUPPLY AND DEMANDManufacturing sites rely on raw material

availability and optimising stock holding

versus cost is essential for uninterrupted

profi table productivity. To further enhance

our tank installations we are now offering

remote inventory management (RIM)

and vendor managed inventory (VMI)

capabilities. RIM and VMI systems provide

security and fl exibility for the management

of raw materials and fi nished product.

SIZE MATTERSTraditionally bitumen tanks have been

designed to hold a single tanker’s worth of

product. However this puts strains on both

the asphalt plant operator and the supplier,

whilst making it diffi cult to comply with

recommended safety guidelines.

Smaller tanks can no longer accommodate

full loads from the larger tankers and in

order to improve bitumen logistics, Cormac

have pioneered the development of tanks

up to 340 m3 capacity. These can be heated

via a variety of sources including electricity,

thermal oil, steam and renewable energy.

The ability to store larger quantities of

bitumen allows plants to even out their

delivery requirements, removing the need

for the traditional early morning delivery

scramble.

Cormac manufacturer a wide range of

mixed material storage equipment to fi t any

make of asphalt plant. Our scope of supply

includes single 50 tonne hot storage bins

and multiple bins with capacities of 120 or

210 tonnes. Bespoke sizes can be supplied

on request. The bins are fi tted with load cell

weighing systems which allow the operator

to weigh out accurately into vehicles whilst

continuing to mix.

We also manufacture a range of mixed

material storage bins for use with high

level plants. These high level units provide

increased storage capabilities and a

horizontal skip car travelling below the

mixer eliminates traditional problems

associated with winch ropes.

Cormac manufacture a full range of rotary

aggregate dryers for most makes of asphalt

plants. Our high-effi ciency internal lifter

design, together with the high density

insulation fi tted to the outside of the

dryer, signifi cantly reduces burner energy

consumption.

Our range of cold feed bins, which are

available in mobile or fi xed confi gurations,

fi t most asphalt plants and range in size

from 6 to 30 tonnes.

The bins come with optional collecting

conveyor and dryer feed conveyor with

variable speed control. They are also

available with coloured profi le sheeting

canopies to protect the aggregates from

inclement weather.

OTHER SERVICESASPHALTBUNDED FUEL TANKS &FILLER SILOSOur range of fuel tanks are manufactured

to meet not only today’s legislation but to

meet the requirements of potential further

regulations. Our horizontal and vertical self

bunded tanks already come with radar level

devices and bund indicators.

We have recently introduced heated fuel

tanks - for use with heavy fuel oil (HFO)

- insulated to maintain the product at the

suppliers recommended temperature.

We also manufacture a wide range of

fi ller silos for use with a range of products

including cement, limestone dust and

hydrated lime.

PUMPS AND VALVES At Cormac we carry an extensive range

of pumps and valves - to complement

our bitumen systems or to supply as

replacement items.

We stock both submersible and external

pumps - the former is ideal for horizontal

tanks whilst the latter is the preferred option

for vertical tanks. The external pumps have

both a pressure relief valve and a triple lip

mechanical seal as standard and can be

heated by electric, steam or hot oil. Both

types of pump come in a wide range of

sizes from 13 m3 to 300 m3 per hour.

We have a vast range of valves in various

sizes operated either manually, electrically

or pneumatically.

Free standing in various volumes they come

with the expected level devices, fi ll line, vent

pipe, high level alarms and when required

dust conditioners and conveyors.
