CAN DRYING - Secomak Supplies Powerstrip Drying System to Carlsberg

Two Powerstrip complete can drying systems are now in use at Carlsberg’s Northampton site.

Cans of beers are dried at very high speed. The Powerstrips are being used after the pasteurising process, and before packing.

Mild detergent based lubricants used to ease the passage of cans through the conveyor system can become concentrated on can tops due to evaporation of water. If moisture form the pasteurising process is left on the can, cans can then become subject to stress corrosion at the final packaging stage.

To counter the problem, can manufacturers, beverage producers and major supermarkets have jointly agreed a new standard of dryness that ensures that the cans are in optimum condition. Secomak’s Powerstrip systems are the first to be able to perform this function at the high speeds required.

High speed lines require special consideration with regard to the handling of the cans through the drying machine, and positioning of the airknives in relation to the can in order to meet the very tight dryness specifications. The Powerstrip system has special features to over come these common can drying problems.

During commissioning, the full range of can sizes was processed, and the optimum machine settings obtained. Digital readouts ensure fast settings for each can size processed.

The performance of the Powerstrip is regularly checked against the dryness specifications to ensure conformity.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
