Type



	Your choices are...
	Air-Cooled		Devices have an integral electric motor or fluid powered fan for the cooling or heat removal of media. Some air-cooled heat exchangers do not include a fan, but have cutouts for aftermarket fans.
	Plate		Plate heat exchangers are often used in low-viscous applications with moderate demands on operating temperatures and pressures, typically below 150° C. Gasket material is chosen to withstand both the operating temperature and the properties of the processing fluid. Heat exchangers, such as gasketed, brazed, welded and semi-weld or hybrid types. The most common type of plate heat exchangers is the gasketed plate-and-frame heat exchanger. Gasketed plate-and-frame heat exchangers consist of a series of channeled plates that are mounted on a frame and clamped together. Each plate is made from "pressable" materials (e.g., stainless steel, nickel, titanium, etc.) and is formed with a series of corrugations. An elastomer gasket is also included with each plate. The gaskets contain the pressure and control the flow of each medium. The gasketed plates are assembled in a pack, mounted on upper and lower guide rails, and compressed between two end frames by compression bolts. The gasket arrangement of each plate distributes the hot and cold media into alternating flow channels throughout the plate pack. In all cases, hot and cold fluids flow counter to each other. Brazed plate heat exchangers consist of specially formed plates, vacuum brazed together to form a heat transfer device. Welded plate heat exchangers require no gaskets. They are fully welded and typically constructed of a single material (usually stainless steel). Semi-weld or hybrid plate exchangers consist of pairs of plates that are laser welded together into cassettes. This allows one fluid to flow in a welded channel and another fluid to flow in a gasketed channel.
	Scraped Surface		Scraped surface heat exchangers typically consist of a jacketed cylinder with rotating rows of scraper blades. The product is pumped through the cylinder while a heating or cooling medium is circulated between the cylinder and the insulating jacket.
	Shell and Tube		Shell and tube (tubular) heat exchangers are used in applications where the demands from high temperatures and pressures are significant. Tubular heat exchangers are also used with fluids that contain particles that would block the channels of a plate heat exchanger. There are several types of shell and tube heat exchangers, including U-tube, straight, spiral, and finned tube. The U-tube design consists of straight length tubes bent into a U-shape. The bundle is fitted with tube supports or flow baffles, depending upon the fluid outside the tubes. The tube assembly is placed in a shell to contain the fluid on the outside of the tube bundle. A head assembly is bolted to the shell to direct the fluid into the tube bundle. To handle heavy fouling fluids or applications where temperature cross conditions exist, straight tube designs are available. (A temperature cross occurs when the fluid being heated has an outlet temperature that falls between the inlet and outlet temperature of the heating medium). Because of the straight tubes, the head assemblies can be removed and the tubes can be cleaned mechanically. Depending upon the tube sheet configuration (fixed or floating), the ability to handle large temperature differences between the fluids may be limited. The body of a spiral heat exchanger is made from two metal strips that are wound around a center to form two spiral channels.

Construction


	Primary Exchanger Material:		Use this specification to specify which material the primary component of the exchanger is to be constructed of, such as the plates, tubes, fins etc. In order to be certain that the material you specify is compatible to the media and temperature involved, please check with the supplier.
	Your choices are...
	Aluminum		Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent metallic element with good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Brass		Brass provides good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.
	Copper		Copper alloy castings are specified for services where superior corrosion resistance, electrical conductivity and good bearing surface qualities are desired. Casting readily produces irregular and often complex external-internal contours. All copper-base alloys are easily plated, brazed, soldered and machined.
	Steel		This is a classification for general-purpose carbon steel or mild steel.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
	Titanium		Titanium and its alloys can be technically superior and cost-effective for a wide variety of aerospace, industrial, marine and commercial applications.
	Other		Other unlisted, specialized, or proprietary material.

	Connection Type:
	Your choices are...
	NPT		National pipe thread can be male (NMPT or MPT) or female (NFPT or FPT).
	BSPT		Connections use any size British standard pipe thread (BSPT).
	Metric		Connections use any size metric pipe thread.
	Flange		Connections use ANSI or SAE rated flanges.
	Solder		Soldering is a common term for a group of joining processes that use a filler metal (solder). Most soldering is performed at temperatures from about 350 F to 550 F.
	Tubular / Tube Fitting		Fittings are similar to a hose bard, typically barbed or ridged in design, so that connecting tubes can be fitted and retained by the ridges.
	Other		Other unlisted, specialized, or proprietary configuration.
