LM110

LM110 is a Mueller brazed plate heat exchanger from the L-Line, a vacuum-brazed stainless assembly with no gaskets, frame, or tie bolts. Herringbone-embossed 316L stainless plates are stacked and brazed at every contact point, which is what lets a package this small carry 362 PSI of working pressure - the braze joints carry the load that a gasketed frame would otherwise need bolts and a head to resist. Overall dimensions are 24.4" by 7.5" with port centers at 20.5" and 3.6", and connections are 2". The model accepts up to 200 plates, ordered in ten-plate increments. Maximum flow is 200 GPM. Copper braze is standard; nickel and stainless braze are available where copper ions are unacceptable, which is the usual specification for ammonia service and for potable and sanitary duty. Temperature range is -320°F to 446°F on the standard copper-brazed build (US-market literature lists -150°F to 445°F). Typical applications are domestic hot water generation, radiant floor and snow melt heat exchange, hydraulic and lube oil cooling, chiller barrels, refrigerant evaporators and condensers, subcoolers, and brewery wort chilling.
