Janitorial cleaning equipment and supplies refer to the tools, machines, and products used for cleaning and maintaining cleanliness in commercial, residential, and industrial spaces. This includes items like floor care equipment, cleaning chemicals, mops, vacuums, pressure washers, carts, and disposable items such as paper towels and trash bags. These products are essential for maintaining hygiene and cleanliness in facilities such as offices, schools, hospitals, hotels, and construction sites.

A gas turbine, also known as a combustion turbine, is a type of internal combustion engine that converts chemical energy from fuel (generally a variety of gases, such as natural gas, process gas, low-Btu coal gas, and others) into mechanical energy through the process of combustion. Gas turbines are commonly used in different applications, including power generation, aviation, and industrial processes. They operate on the principle of continuous combustion, where fuel (gas) and air are continuously mixed and burned to produce a high-speed and high-energy exhaust gas stream.

A geothermal heat pump is also called a ground source heat pump. The system uses efficient renewable energy technology and is gaining popularity among users in both residential and commercial buildings. Geothermal heat pumps are used in buildings for space cooling and heating, as well as water heating. The main advantage of geothermal heat pumps is that they concentrate naturally on existing heat instead of producing heat from the combustion of fossil fuels.

Handling equipment is mechanical equipment used for the movement, storage, control, and protection of goods throughout the process of manufacturing, distribution, consumption, and disposal. Lifting equipment is used for lifting and lowering loads. Advanced equipment can perform complicated tasks with relative ease of movement, especially when compared to traditional handling and lifting equipment. Handling and lifting equipment include cranes, forklifts, conveyor belts, and hoists.

HVAC systems are used for heating, cooling, filtering, and ventilating the air within enclosed spaces or buildings to maintain a comfortable environment for the people living and working within the buildings. Other than space heating and cooling purposes, HVAC systems are also used for regulating the humidity and moisture level in the air and controlling the number of airborne particles.

Industrial machinery remanufacturing involves the process of refurbishing and restoring used or worn-out industrial machinery to like-new conditions, often exceeding its original performance standards. The goal of industrial machinery remanufacturing is to extend the lifespan of machinery, reduce downtime, and provide a cost-effective alternative to purchasing new equipment.
