Fulton electric boiler provides a cure for Prysmian Group
B
ristol-based heat transfer specialist Fulton has
supplied Prysmian Group’s Bishopstoke facility a skid- mounted electric boiler and ancillaries, steam from which is being used to cure the insulation applied to the company’s electric cables. Commenting on the process, Prysmian’s Nicolas Chevaux explains that curing is used
to strengthen and increase the heat resistance of the insulation. “Without the process, the insulation would have a lower temperature resistance and hence the cable would have a lower current rating.” Following manufacture, batches of up to 16 drums are placed into a container where steam from Fulton’s EP100 Electropack boiler system is injected to start a curing process that can take up to twelve hours at 80°C. The cable that uses this particular curing process is Prysmian’s 6491b low fire-hazard wiring cable – a BS7211 BASEC approved single- core conduit cable for wiring applications in buildings
such as stadia, hospitals,
cinemas/theatres, etc. Unlike PVC-based thermoplastic insulation found on standard 6491x cable, Prysmian’s 6491b cable uses a thermosetting low-smoke material that doesn’t generate dense acidic fumes when burnt.

anything on the top of your foot, you will know exactly the potential damage that can be done to this sensitive part of the body. In response to customer feedback highlighting the need for a comfortable, flexible metatarsal boot, Arco, the UK’s leading supplier of personal protective equipment and workwear, has developed the Arco Internal Metguard Safety Boot made with innovative Poron® XRD foam. Poron® XRD is a flexible, contouring and impact absorbing foam that is flexible under normal conditions but under sudden high impact, it instantly firms to create a protective shield. The foam takes the absorption of the strike leaving the foot unharmed. Prior to impact the foam remains comfortable and non-restrictive as it returns to its ‘resting’ state. The wearer has maximum and reliable protection on every hit as the molecules in the foam will not break down on impact or over a period of time. The foam is manufactured into the tongue, removing the need for an overlaying level of protection, providing metatarsal protection without affecting the flexibility and ultimately not compromising safety and comfort while maintaining the look of a traditional workboot.

Totally integrated lightweight head and eye protection with EVOLite + EVOSpec
SP’s EVOLite + EVOSpec is the lightest, yet strongest, combined safety helmet and protective eyewear solution on the market, weighing in at a mere 332g, considerably less than any other integrated head and eye protection product. Used

together, the easily-assembled combination of EVOLite safety helmet and EVOSpec eyeshield ensure absolute protection for both head and eyes. Designed to fit quickly and seamlessly together, the clear, polycarbonate, retractable EVOSpec slides snugly and securely up into the helmet shell when not in use and can be lowered to protect the eyes in a split second. This not only allows unrivalled protection of the lens, but also leaves the field of vision completely clear when eye protection is not needed. The EVOLite safety helmet and its EVOSpec eyeshield complement each other perfectly and solve the problem of fulfilling mandatory head and eye PPE requirements in one fell swoop, avoiding the risk and hassle of wearing separate helmet and eye protection that have not been developed to be used together. The EVOLite is without doubt the lightest EN397 protective headwear solution on the market.

Seabrook Crisps - Crunch time for crisp pump
component to fail. Should that scenario occur, then the immediate availability of either a replacement part or repair facility is the only solution.
W When the failure of a hot oil pump occurred at Seabrook Crisps in Bradford
in early 2013, the prospect of having to shut down production to remove the pump from service became a reality. Minimising the shut down period was essential and that meant turning to a specialist pump repair and service provider which Seabrook Crisps knew would solve their dilemma. That provider was AxFlow’s Service Division in nearby Huddersfield.
Having worked with Seabrook Crisps for around four years, AxFlow’s team of
engineers were only too well aware of the consequences of a prolonged shutdown and pulled out all the stops to get the Cornell Hot Oil pump back on line. The time taken from collecting the pump, doing the repairs and returning it to the site was just six hours. “This is a specialist type of pump for the food industry and at Seabrook Crisps it is in operation 24 hours a day pumping thermal fluid at a temperature of 255ºC, so it is subjected to considerable workload,” commented Mark Redgrove, AxFlow’s Technical Support Manager.
The Cornell Hot Oil pump serves two purposes: moving thermal fluid into a
heat exchanger on the fryer containing five tons of sunflower oil in which the crisps are cooked; and feeding thermal fluid into heat exchanger on the blancher. Thermal fluid is a slightly viscous mineral oil and the fluctuating temperature of this has an adverse effect on the mechanical seal. The rise and fall in the temperature of the thermal fluid causes the mechanical seals to move, and it is this movement that leads to seal failure. The working life of the mechanical seal can vary between 12 and 18 months, but predicting seal failure is imprecise. Regrettable though seal failure is, according to Tommy Brown at Seabrook Crisps, the Cornell Hot Oil pump is the best pump for the job.
Having been called in to look at the pump, AxFlow removed it from service and took it to the Huddersfield plant where it was stripped and inspected. This

revealed that the mechanical seal, bearings, lip seals and gaskets all needed renewing and work commenced immediately. Once the sealing arrangement was completed and installed in the pump, the pump was hydrostatically tested with water in accordance with AxFlow’s standard test procedures. “Mechanical seal repair and replacement is one of the many engineering services that we offer at Huddersfield,” says Mark Redgrove. “Fortunately for Seabrook Crisps we were familiar with this type of food industry pump and sealing arrangement and had the necessary components available. As a result, the production down time at the factory was kept to a minimum.”
