Seals Help Food Manufacturers Detect Contamination

Eriks Sealing Technology has developed a range of metal-detectable seals for use in sensitive applications where the ability to detect and contain contamination is vital. The elastomers are detectable on production lines by conventional metal-detection equipment, so help to decrease the risk of polymers finding their way into the finished product and supply chain, reduce product wastage, eliminate costly product recalls and reduce equipment-maintenance costs.

The materials are FDA and 3A (class 1) compliant to meet the needs of the food, beverage, pharmaceutical and dairy industries. The compounds are easily detected by most of the conventional metal-detection techniques that are already being employed on production lines. Should a piece of elastomer be detected, the production line can be stopped immediately, contaminated products can be easily removed before they reach the supply chain and the problem on the production line can be quickly rectified.

The seals are manufactured from NBR, EPDM, FKM and Silicone compounds to form metal-detectable O-rings, sanitary gaskets and other moulded seals. Particle sizes as small as 2mm can be readily detected. As well as offering FDA compliance for the food and pharmaceutical industries, and 3A Class 1 (sanitary standard 18-03) compliance for the dairy, food and other hygiene-sensitive industries, these seals can be used as part of a HACCP (Hazard Analysis and Critical Control Points) programme.

These procedures identify potential hazards so that key actions can be taken to reduce or eliminate the risk of hazards being realised. The seals are available in blue or black for easy product identification and offer extended lifetime performance. The seals operate over a temperature range of -60 to 220C and can be used in a variety of applications.

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.
