Fire dampers (or fire shutters) are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to prevent and isolate the spread of fire inside the ductwork through fire-resistance rated walls and floors.[1] Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside…
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.[1] An air handler is usually a large metal box containing a blower, furnace or A/C elements, filter racks or chambers, sound attenuators, and dampers.[2] Air…
An air washer is an air purifier that cleans the air using water to trap pollutants and impurities. Air washers typically consist of a fan that draws air through a series of damp pads or plates, where the water in the pads or plates absorbs dust, dirt, and other particles from the air.
A fan coil unit (FCU), also known as a Vertical Fan Coil-Unit (VFC), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or with central plant cooling. FCUs are typically connected to ductwork…
Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat.[1] The heating element inside every electric heater is an electrical resistor, and works on the…
