""Underfloor heating (UFH) is a heating system that uses embedded pipes or electric heating cables beneath a finished floor so that heat radiates steadily from floor level.
It is a form of central heating using conduction, radiation and convection. Underfloor heating (UFH)’s advantages main include two aspects: it provides better quality heating without draughts or dry air, but also that, because of its low operating temperature; it can be easily linked in with alternative heating sources that output at the same low temperatures."
Ultrasonic welding is the joining or reforming of thermoplastics or other materials through the use of heat generated from high-frequency mechanical motion. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied force, creates frictional heat at the plastic or other materials components' mating surfaces (joint area) so the material will melt and form a molecular bond between the parts.
Thermal drying technology is based on removal of water from dewatered solids which accomplishes both volume and weight reduction. The added benefit of thermal drying is that it typically results in a product with significant nutrient value. Typically, dewatered solids (at approximately 18% to 35% dry solids content) are delivered to a thermal drying system, where most of the water is removed via evaporation resulting in a product containing approximately 90% solids. In the thermal drying system, the temperature of the wet solids mass is raised so that the water is driven off as a vapor. By removing most of the water from the solids, thermal drying results in a significant reduction in both volume and mass.
"Overhead Cranes is a type of crane found in industrial environments. An overhead crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the bridge. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane (USA, ASME B30 series) or a goliath crane (UK, BS 466).
Mobile crusher and screener machine is designed to crush large rocks into small rocks, gravel or dust. A crusher holds material which is to be crushed between two parallel solid surfaces. Sufficient force is applied to the material by crusher that generates enough energy to crush material by fracturing or deform the material. Screening is the process of taking granular ore material and separating it into multi-grades by size. Various types of screeners are used for the screening process. Both crusher and screens are used in the mining industry to crush the rock and then separate those using screeners.
The pipe wrench (US), Stillson wrench or Stillsons (UK) is an adjustable wrench used for turning soft iron pipes and fittings with a rounded surface. The design of the adjustable jaw allows it to lock in the frame, such that any forward pressure on the handle tends to pull the jaws tighter together. Teeth angled in the direction of turn dig into the soft pipe. They are not intended for use on hardened steel hex nuts or other fittings because they would ruin the head; however, if a hex nut is soft enough that it becomes rounded beyond use with standard wrenches, a pipe wrench is sometimes used to break the bolt or nut free. Pipe wrenches are usually sold in the following sizes (by length of handle): 10, 12, 14, 18, 24, 36, and 48 inches, although smaller and larger sizes are available as well. They are usually made of cast steel. Today, aluminum is also used to construct the body of the wrench, while the teeth and jaw remain steel. Teeth, and jaw kits (which also contain adjustment rings and springs) can be bought to repair broken wrenches, as this is cheaper than buying a new wrench.
