MKS
The MKS Series 49UL is a thermal management system for heater jackets. The MKS Series 49UL uses polyimide or PTFE-woven heater jacket options. The MKS Series 49UL has a temperature range up to 200°C.[1][2]
The Series 49UL uses heater jackets that wrap around components to provide controlled heat. The system combines power and communications in one assembly to simplify installation and networked control.[2]
The Series 49UL controller supports RS485 Modbus RTU communications and can be accessed through a tablet-based application. The controller provides adjustable temperatures, alarm control, status indication, remote setup, and diagnostics across a heater network.[2][3]
The heater jackets use either Polyimide or PTFE materials. The heater construction is intended to support high operating temperature, thermal efficiency, low particulate generation, and low volatile organic compound outgassing.[2]
The Series 49UL fits into process lines where components, lines, or auxiliary vessels need stable temperature control. The system is used to help prevent condensation and solidification in heated process hardware.[2][4]
The Series 49UL is used with process equipment such as gas analyzers, endpoint detectors, bubbler cylinders, mass flow controllers, manometers, and valves. The system is also applied to analytical instruments, evaporators, chambers, and custom heater assemblies.[2]
MKS announced the Series 49UL Thermal Management System on February 11, 2020.
