Electric

Electric Heat Exchanger. Similar in concept to shell and tube heat exchangers, except the heat source is from an electrical element rather than a heated fluid. This type of heat exchanger has an electric heating element placed inside of a tube designed to specifically accommodate the process pressure and temperature of the fluid to which the heat is being transferred. Special fittings at the end of the tubes enable electrical and fluid connections. The intimate contact of the heated tube with the fluid to be heated results in high-energy efficiency and fast response. These exchangers are capable of precise temperature control.

Electric Heaters

Electric Heaters. Used to heat a variety of materials, industrial electric heaters come in many sizes and configurations for purposes of comfort heating to immersion heating. Industrial heaters have myriad applications, from heating tanks filled with liquids and gases to warming warehouses and exposed areas. Industrial heaters heat everything from air and gases to oils and water.

Enclosures

Control Panel Enclosures. These enclosures are cabinets designed for housing electrical or electronic equipment, protecting equipment from the environment, and for protecting users from shock or injury. Front panels provide access to switches, knobs, and displays. The National Electrical Manufacturers Association (NEMA) publishes standards for the performance of various classes of electrical enclosures. These standards cover corrosion resistance and the ability to protect from rain and submersion. Some enclosures are provided with partially punched openings that can be removed to accommodate cables, connectors, or conduits.

Enviromental Chambers

Environmental Chambers: Equipment used to perform scientific testing of products under a variety of stresses and environmental conditions. These chambers can simulate environments with extreme temperatures, humidity levels, altitude, radiation, wind, bacteria, dust and chemical exposure.

Expansion Joints

Pipe Expansion Joints: These flexible joints, which are designed to withstand the internal pressure of the connected piping system, compensate for axial, lateral, and angular deflections in piping systems. Pipe expansion joints are commonly used in piping systems handling high temperature steam or compressed air. They are designed to operate under various environmental and pressure conditions, and are of several common types: flexible expansion loops, and bellows made from metal, rubber, or plastic.

Explosion Suppression & Flame Arrestors

Explosion Suppression and Flame Arrestors. Explosion and flame are related hazards with different protection methods. A flame arrester is a device installed in a process to stop the propagation of a flame traveling along a pipeline by extinguishing it. They are used on storage tank vents and gas pipelines. Flame arresters force a flame front through channels too narrow to permit the continuance of a flame. An explosion suppression system consists of an explosion detector, control system, and suppressor unit. The suppressor unit stores the suppressant under pressure for release at high speed. A good suppressant should have the following properties: quenching ability - rapid heat absorption from the combustion zone by energy transfer; dilution - suppressant concentration should dilute the inburned mixture a point where it is non-flammable; wetting - unburnt dust particles are rendered non-flammable by absorption of liquid suppressant; chemical action - chemical composition of the suppressant directly interferes with combustion.
