    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.

  3. Service plan - Wikipedia

    en.wikipedia.org/wiki/Service_plan

    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.

  4. Metal hose - Wikipedia

    en.wikipedia.org/wiki/Metal_hose

    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.

  9. Fan coil unit - Wikipedia

    en.wikipedia.org/wiki/Fan_coil_unit

    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.
