MachineValley Half Coil Reactor is engineered for processes where conventional full-jacket heat transfer isn't sufficient, either because the heating/cooling medium operates at higher pressure, or because the process demands faster, more localized temperature control. Instead of a single enclosed jacket space, half-pipe (semi-circular) coils are welded in a helical pattern directly onto the vessel's outer shell, creating multiple independent flow channels for steam, hot oil, hot water, or chilled water/glycol.

This Half Limpet Coil Reactor construction offers several advantages over a plain jacket: it can safely handle higher working pressures on the heat-transfer side, provides more even heat distribution along the vessel height.

Half-Limpet Coil Vessel itself is available in SS304, SS316, or mild steel (with lining options for corrosive applications), and can be paired with anchor, turbine, propeller, or high-speed disperser agitators depending on the batch viscosity and mixing intensity required. 

Standard fittings include a manhole, inspection window, sampling valve, bottom discharge valve, safety relief valve, and thermometer pocket, with insulation cladding recommended to preserve the efficiency gains of the coil design. Optional additions include multi-zone coil control panels, vacuum operation, PLC/PID temperature automation, and mechanical seal upgrades.
