AT40M specifications
Description
AT40M is the M-series plate configuration of the Mueller Accu-Therm AT40 frame. It is a distinct part from the base AT40: the frame and port geometry are shared, but the plate pressing is not, so an M plate and a base plate are not interchangeable in a pack and their gaskets differ. The M plate is a high-pressure pressing per the Accu-Therm I&O manual plate-code table, and it is the series Mueller carries as a stocked replacement plate assembly on this frame (codes such as 40MH, 40MV, 80M, 120M, 405M, 805M). It is the plate most commonly found in installed industrial units of this size. Frame geometry is unchanged - 70-1/4" by 27" plates on 4" ports, packs from 33-7/8" - 159-7/8", roughly 99 - 2,292 sq ft of surface at about 4.2 square feet per plate, and water flow to 800 GPM. Gaskets attach by the Loc-In method. Frame styles offered: F Frame - intermediate size, bolted head and tail plate; B Frame - for larger units, plates hang from the upper guide bar; capacity to 900 plates. If you are matching a nameplate, the series letter is part of the part number and needs to carry through to any plate or gasket order.
