Commercial Air Coolers for Use in Food Preparation

Alfa Laval has developed a portfolio of Eurovent-certified, commercial air coolers for duties in food-preparation areas, chilled distribution depots, supermarkets, petrol stations and restaurants. Called Optigo, the first units released under this name are the CS20 and CS30 air coolers. With an evaporation range of from 100 to -300C, both are suited for general applications in small- to medium-size cooling and freezing rooms.

They incorporate a number of new features, including a coil pattern; energy-efficient, dual-speed EC fan motors (200 or 300mm diameter) as standard and a new supply set up that saves installation time by making mounting quicker and safer. Both types are characterised by an ultra-slim silhouette, making them simple to install even in confined spaces. For instance, the CS20 model is only 15cm deep, which means it can also be wall-mounted to make the most efficient use of the available space. Yet it is available in six different capacities providing airflow of 513 to 1,671m3 per hour.

The CS30 model offers up to 20 variations, the largest of which provides 4,240m3/hr airflow. All of these units operate to a design pressure of 31 Bar. In addition, special versions capable of handling 80Barg are available to order. They can be used with H(C)FC, brine or CO2 as the refrigerant. The smart but durable casing is aluminium coated with a thick epoxy coating to RAL 9003 for a long working life.

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.
