Nautilair Launches Blowers For Gas-Fired Burners

Nautilair 8.0 (204mm) blowers for gas-fired burner systems deliver a measured air/fuel mixture to optimise combustion and reduce nitrous-oxide and carbon-monoxide emissions. These high-efficiency variable-speed pre-mix brushless blowers are designed to resolve system design or performance challenges often associated with conventional fixed-speed or two-speed blowers, intake-damper systems on fixed-speed blowers and inverter-driven variable-speed blowers.

Their brushless DC motor technology promotes virtually maintenance-free operation exceeding 20,000hrs in commercial and residential boilers, water heaters, furnaces, foodservice equipment, kilns and fuel cells. These single-phase, standard output blowers can achieve maximum sealed pressure capabilities up to 9in of H2O and maximum open flows exceeding 100CFM. They can accept line voltage input of 120V AC (internal electronics convert AC input to DC).

The compact, lightweight and rugged blowers incorporate polypropylene housing and impeller; long-life and sealed ball bearings with high-temperature grease; and a sealed and moulded fan housing. Speed can be adjusted internally with an onboard potentiometer or with an external PWM or DC control that actively varies blower performance. Onboard Intelligen controller electronics integrate a factory-programmed digital-signal processor (DSP) and add-on expansion cards, and other options can be specified to meet particular application requirements.

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.
