ELECTRIC LIQUID & PROCESS FLUID HEATERS
Corrosive Chemical Liquid Heater
Custom corrosion-resistant electric heating equipment for chemical liquids and demanding process fluids.
The Corrosive Chemical Liquid Heater is designed for controlled heating of chemical liquids, aqueous solutions and process fluids where composition, concentration and temperature require careful material and seal selection.
The design can be customized in heating power, flow, pressure, connection, shell material, element sheath, watt density, seal, control and protection. Final material selection is based on the customer’s complete fluid data and operating conditions.
Product Overview
The Corrosive Chemical Liquid Heater is an industrial inline or immersion heating unit for chemical liquids and process fluids that cannot be treated as ordinary water or oil service.
A typical inline design includes a pressure-bearing shell, inlet and outlet, removable flanged element bundle, terminal box, insulation, sensors, drain and vent connections. Tank or vessel duties can use a compatible immersion assembly.
The main selection issue is chemical compatibility. Fluid name alone is not sufficient; concentration, temperature, impurities, pressure, flow, cleaning method and possible phase change must be confirmed before materials are selected.
Xiangyuan Machinery can supply the heater only, the heater with an independent control cabinet, or a package including instruments, valves and piping selected for the confirmed process fluid.
Key Features
The Corrosive Chemical Liquid Heater can be engineered around the actual medium, duty, installation and control requirements of the project.

Structure, Materials, Control and Safety
Structure of the Heater
An inline chemical-liquid heater normally uses a pressure-bearing shell with compatible wetted surfaces and a removable flanged heating element bundle. The internal flow path is arranged to provide suitable velocity and avoid stagnant hot zones.
The unit can include vent and drain connections, temperature and pressure ports, insulation, external cladding, compatible gaskets, terminal enclosure and maintenance supports. A vessel version can use a flanged immersion bundle.
The structure is customized for cleaning, flushing, drainage, element removal and prevention of trapped liquid. These details are confirmed from the process and maintenance method.
Materials and Customization
Material selection must be based on complete chemical data. SS316L may be suitable for some duties, while other fluids may require different alloys or non-standard wetted components. No single material should be assumed suitable for all corrosive chemical services.
Element sheath material, weld filler, shell, flange, gasket and sensor sheath should be reviewed as one wetted-material system. Operating temperature can significantly change corrosion behavior.
Element diameter, watt density and spacing can be adjusted for fluids that may decompose, polymerize, crystallize or form deposits at elevated surface temperature.
Control System
Temperature can be controlled by PID and SCR or staged power regulation through an independent cabinet or the customer’s PLC/DCS. Outlet-liquid temperature is commonly used for inline duty; vessel temperature can be used for batch duty.
Optional monitoring includes element sheath temperature, flow, level, pressure and upstream or downstream process conditions.
Control logic can prevent energization without confirmed liquid coverage or flow, limit power during start-up and generate alarms for high temperature, low level, low flow or electrical fault.
Safety Protection
Typical protection can include an independent over-temperature cutoff, low-flow or pump interlock, low-level and dry-heating protection, pressure monitoring, ground-fault protection, protective grounding and emergency stop.
The heater must not be energized until the heating elements are fully wetted or the required liquid flow is confirmed. The operating procedure should also prevent unexpected concentration changes, crystallization, polymerization or gas generation around the heating surface.
For hazardous-area applications, explosion-proof terminal boxes and matched electrical configurations are available. Relevant explosion-proof products have obtained Chinese explosion-proof certification Ex db IIC T1–T6 Gb. The final configuration is confirmed according to the liquid hazard, site classification and actual operating conditions.
