Section 1:
Introduction
Process Technology’s SH In-Line Heater is designed to pr ovide energy-efficient, safe heating of solvents and nonflammable gasses (such as nitrogen). Wetted surfaces of the heater are constructed of chemically milled (etched) 316
stainless steel. The heater is a compact, completely welde d, insulated, pressure resistant vessel. It is designed for use in
either Single Pass or Multi-Pass Flow applications. The junction box includes two threaded couplings for optional gas
fittings, which could be used to keep the junction box under positive gas pressure.
The SH In-Line Heater can withstand operation at a variety of temperature and pressure conditi ons. The maximum
operating condition for the SH In-Line Heater is 160
o
C at 50 PSI.
Warning: Safe operation of the equipment requires that each of the temperature sensors be wired
properly into a customer supplied control system, in accordance with local regulations, where applicable.
Refer to Section 3.5 for additional information. Failure to use the supplied temperature sensors for their
intended purposes may void all or part of the equi pment warranty. Consult factory for technical assistance.
This SH In-Line Heater consists of:
316 stainless steel fluid path
304 stainless steel, insulated housin g
Two J- type thermocouple Heater over-temperature se nsors
One J-type thermocouple Process control sensor
TCO, over-temperature fuse
½-inch OD stainless steel tube inlet and outlet connecti ons
Optional Heater Equipment may include:
E or K-type thermocouples or RTD temperature sensors
Custom inlet and outlet connections
This SH In-Line heater control system consists of the following:
Solid state control relays
PID temperature controller (series E5CK)
Over-temperature controller
Ground-fault protection (Earth leakage protection)
Optional System Equipment may include the following:
Circuit breaker and electrical disconnect
Built to SEMI and CE standards
Remote control electrical interface
RS-232, RS485 serial communication interface
Warning: The heater design and over-temperature protection devices vary depending on the specific
application. This heater (reference model and serial numbers in Appendix) was designed and built for a
specific inert gas heating application. This manual provides information for inert gas heating applications
ONLY. This heater should not be used to heat process solvents or combustible fluids.

SAFETY NETWORK:
The SH inline heater is protected from accidental damage or unsafe operating conditions with a network of safety interlocks. The safety
interlocks will disengage power to the heaters until power is manually restored at the control. The safety interlocks offered on the SH
inline heater are listed below.
TCO Heater Over-Temperature Fuse:
Any over-temperature situation will cause the main load contactor to disengage, and sound the audible alarm. This will require a manual
reset of the heater once the overheat event has been corrected. The over temperature sensor has a fixed setting of 169°C (336°F).
(Maximum Heater Temperature)
Safety Limit Controller (SLC):
This over-temperature controller is a separate controller mounted inside the control enclosure. It uses a separate temperature sensor to
monitor the hot-zone temperature in the heater.
This over-temperature controller has two different settings:
1. Over-temperature cutoff (SP2). This setting needs to be adjusted manually by the customer, to be set at 135°F (57°C).
This setting will cut off power to the heaters if the internal temperature rises above this value, but will automatically reengage the heaters when the temperature drops below this value. This is not an alarm set point.
2.
High Limit (HSP1). This high-temperature alarm setting is set at 145°F (63°C). If this temperature is detected at this
sensor. the controller will disengage the main load contactor and sound the audible alarm. This will require a manual
reset of the heater once the overheat event has been corrected.
Heat Sink Thermal Cutoff:
The heat sink for the solid state relays (SSRs) is equipped with a bimetallic temperature switch. If the cooling fan on the heat sink wer to
fail, the temperature of the het sink would gradually rise, resulting in eventual SSR failure. This switch willl cause the main load
contactor to disengage, and sound the audible alarm. This will require a manual reset of the heater once the overheat event has been
corrected. The over temperature sensor has a fixed setting of 176°F (80°C). (Maximum Heat Sink Temperature)
