A unit load is a collection of goods packed for easy transportation, often stacked on a pallet and wrapped together. It can be any quantity of product similarly packed for transport, from pushcart-sized units to intermodal shipping crates. The load unit is secured as one solid piece, and can be wrapped using packing wrap or […]
A distillation unit separates mixed liquids by heating them until each component reaches boiling point. It consists of a boiler, a column, a condenser, and storage vessels. Different types of distillation units include fractional, simple, steam, and vacuum distillation. A distillation unit is a set of machinery that is used to separate two or more […]
Coker units recover valuable elements, including petroleum coke, from residual oil or pitch through thermal cracking. The coke is collected in a drum and ejected by water jets for further processing into fuel or anode grade products. A coker unit is a thermal cracking process in the petroleum refinery industry used to recover valuable elements, […]
An HVAC unit regulates a building’s internal temperature and climate through centralized heating, ventilation, and air conditioning. It draws warm air into the system, cools it over refrigerated coils, and sends it back into the building. The heating function works similarly. HVAC systems also improve indoor air quality through ventilation and filtration. Filters protect the […]
An A unit is a manned master unit in multiple locomotive train configurations, controlling the B units through a cable link. B units lack driver amenities and are controlled by A unit conductors. A units can be converted to B types if necessary. An A unit is a railway locomotive used as a manned master […]
Power distribution units (PDUs) manage power distribution to multiple devices, ensuring essential equipment receives sufficient power. There are two types: rack-based and heavy floor-mounted. Remote management is increasingly common for ease of access and safety in emergency situations. A power distribution unit (PDU) is a form of equipment used to manage the allocation and distribution […]
Slewing drives consist of a radial gear, axial worm shaft, and drive component, used to transform axial motion into radial motion. They have many applications, including wind and solar energy systems, and are made of materials such as steel and phosphor bronze. They have a long history, dating back to ancient Greece. The term “slewing […]
Pumping units are used to extract oil from wells in oil fields. Reciprocating piston pumps are commonly used. The head of the device swings up and down to create pressure. Personnel inspect and maintain the units. Companies offer a range of designs and support for their products. A pumping unit is equipment used to extract […]
A tractor unit is a large vehicle that can tow trailers and has between two and five axles. It can uncouple from one trailer and hitch up another before the first one is unloaded, making it versatile for transporting goods. Tractor units can tow shipping containers, tank trucks, and other types of trailers. They are […]
A terminal unit is an outlet in ductwork that supplies air to a room. It can have heating and cooling coils and is installed by a technician. The size and placement of the unit must be considered for efficiency. Unused ductwork can be closed off, and cleaning is necessary to reduce dust and bacteria. A […]
A switchboard, also known as a residential circuit breaker box, divides the electrical circuit of a household into separate circuits with their own switches. Older switchboards use fuses, while modern ones use circuit breaker switches. Bypassing fuses is dangerous and most US mortgage lenders require circuit breakers. Each breaker or fuse is labeled in amps […]
A hauling unit is used to remove damaged casing and drilling equipment from a well. Smaller units are used in agricultural pumping applications. The construction of the unit varies, but its purpose is to remove systems without digging. The units are portable and mounted on heavy-duty trucks. A hauling unit is one of the oilfield […]
Condensing units convert gas to liquid through cooling and are used in refrigeration, air conditioning, chemical reactions, and power plants. Surface condensers recycle steam in power plants, while laboratory condensers distill water. Direct contact condensers combine identical substances in different forms. A condensing unit is a device which is used to condense a gaseous substance […]
Condensing units are heat exchangers that condense gases into liquids through cooling. They are used in refrigerators, air conditioners, chemical reactions, and power plants. Surface condensers are commonly used in steam power plants to increase efficiency by recycling steam. Air conditioner condensing units have three essential components: condenser, compressor, and blower/fan. Laboratory and chemical condensers […]
Dementia is a group of symptoms affecting brain function, leading to memory loss, paranoia, and difficulty learning. Dementia units should be quiet, have locked exits, and single-story buildings with a circular wandering zone. Staff ratios and training are also important. Dementia is characterized by a group of symptoms that negatively affect a person’s quality of […]
Unit testing is a process where developers evaluate the function and performance of small software modules. Developers write small programs to verify inputs, behaviors, and outputs. Unit testing is an ongoing effort to confirm code works as intended and is an integral part of the development process. It encourages early discovery of problems, reducing errors […]
A floating point unit (FPU) is a processor block that performs floating point arithmetic, often accessed through the same addressing arrangements as the rest of the processor. Many processors do not include an FPU, but most processors and software systems implement the IEEE standard for floating point operations. FPUs can perform many operations, including trigonometric […]
A clock drive is used in astronomy to automatically move a telescope at the same speed as the Earth’s rotation, allowing for steady observation and astrophotography. It rotates the telescope at one rotation per sidereal day, and is now electrically powered. It reduces human error in astrophotography. A clock drive is used in astronomy, especially […]
Organizational units (OU) group and organize components of an organization’s structure for management. X.500 standards developed OU for electronic directory services. Users and groups can be organized into OUs for easy management. OUs are also used for digital security certificate management. An organizational unit (OU) is a method used in computer systems administration to group […]
The power management unit controls the power functions of Apple computers, acting as a powerful microchip that coordinates essential activities. It monitors power connections, battery status, and system components, and can malfunction due to power surges. Malfunction signs include the inability to initiate a battery charging session or recognize devices. The power management unit, or […]
