Dimplex Launches Air-Eau Inverter Heat Pumps

Dimplex has launched the Air-Eau range of inverter-driven heat pumps, offering energy efficiency and performance, low noise levels and easy installation. With outputs from 6-16kW, the range covers domestic applications from small, well-insulated new build homes, to retrofits in existing homes which will have higher heat requirements. The range achieves very high CoPs of up to 4.7 across a range of operating temperatures.

Designed to work efficiently with underfloor heating, Dimplex Smartrad radiators or conventional radiators, Air-Eau heat pumps offer variable water flow temperatures between 35degC and 55degC for maximum space heating comfort, with weather compensated flow temperature control for improved efficiency. At the heart of the Air-Eau heat pump is a variable speed, inverter controlled compressor, which allows the heat levels delivered to be matched closely to the heating requirements of the building, as ambient temperatures change.

This means that in cold weather heat pump capacity is maintained, eliminating any need for supplementary back up heating, while at warmer air temperatures, heat pump output can be reduced, helping to improve efficiency. A key feature for domestic use, Air-Eau heat pumps have been designed for very low noise emissions; sound pressure levels are typically as low as 50dB at 1m. The new range also features a quiet mode, so noise is kept to an absolute minimum, making it suited for overnight use. The heat pumps are very straightforward to install thanks to the range's monobloc configuration.

With all the system components contained in the outdoor heat pump itself, including heating system circulating pump, expansion vessel and back up flow boiler, only the hot water cylinder and control valve are located inside the building. Additionally, an Air-eau system uses water pipes rather than refrigerant lines to connect the heat pump to the building, meaning there's no need for refrigerant handling expertise. The Air-Eau range is available in a choice of four outputs from 6-16kW to suit a range of applications and can be supplied together with a matched EC-Eau cylinder for easy specification.

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.
