The standard SCH-1 heater has an electroless nickel-plated brass
reservoir and fluid passage body (4). The heater is mounted at the back
of the workcell, near the fluid pump and consists of an electrical
enclosure (5) and a fluid-heating reservoir.
A platinum RTD is used to provide temperature feedback from the fluid
passage body to an adjustable digital temperature controller at the front
of the workcell. The fluid heating reservoir consists of a fluid passage
body and high-pressure housing (3). The heater cartridge and heat
limiter are located within the fluid passage body.
