Heated hose assembly. Heated hoses are hoses used for transporting liquids or molten materials where integral heat is needed for temperature control. Heated hoses are used in bonding technology, filling and dosing systems, medical technology, chemical, pharmaceutical and food industry, extruder applications, and research & development.
Whether an extended service plan is worth the extra cost depends on the item and the perceived value by the consumer. Basic service plans on desktop computers, for example, typically come close to the actual average repair cost of a system, with the retailer using the service plan as a way to keep the customer from going to a competing service center.
The first metal hose was technically a stripwound hose. It was invented in 1885 by the jewellery manufacturer Heinrich Witzenmann (1829–1906) of Pforzheim, Germany, together with the French engineer Eugène Levavassèur. The hose was modelled after the goose throat necklace, a piece of jewellery that consisted of interlacing metal strips.
1.25 V or 1.4 V AC from a separate heater winding on CRT horizontal-output transformers, in half-indirectly heated EHT rectifiers; E – 6.3 V parallel heater; for 3-cell lead-acid vehicle crank batteries (mobile equipment) and for AC mains or horizontal-output transformers; F – 12.6 V DC parallel heater for 6-cell lead-acid vehicle crank ...
In 1934 the company was publicly listed as "Ideal Boilers and Radiators" (capital £750,000) in order to raise cash for a factory extension. [25] By 1938 a new plant producing vitreous sanitary ware had begun operation. [26]
Thick-film heaters are a type of resistive heater that can be printed on a thin substrate. Thick-film heaters exhibit various advantages over the conventional metal-sheathed resistance elements. In general, thick-film elements are characterized by their low-profile form factor, improved temperature uniformity, quick thermal response due to low ...
IEC 60917 Modular order for the development of mechanical structures for electronic equipment practices; IEC 60918 PVC insulated ribbon cable with a pitch of 1.27 mm suitable for insulation displacement termination; IEC TR 60919 Performance of high-voltage direct current (HVDC) systems with line-commutated converters
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
