Manual Introduction
Congratulations on your decision to purchase the THJ80 ThermoJet for your thermal
conditioning application. Used and maintained properly, your THJ80 will give you many years
of outstanding temperature testing performance.
This instruction manual contains all the information needed to install, use and maintain your
THJ80. Please read this manual completely and become familiar with the THJ80 before
attempting to operate it. Take special note of the preventative maintenance section. Timely
maintenance will prolong the life of the ThermoJet. The average operator is not expected to
perform repairs without qualified assistance. In the event the ThermoJet needs repair, please
contact your local FTS representative, or call the SP Service Department.
FTS reserves the right to improve the design, quality, and performance of all its products
without notice.
System Description
The THJ80 is a mechanically refrigerated system designed to provide high volume, high
velocity, temperature controlled airflow to an enclosed, thermally-isolated environment. A
complete system consists of a base unit cabinet, a flexible air delivery assembly, a holding
arm (optional), a shroud (optional), a system controller, and a touch screen.
The base unit cabinet contains the refrigeration system, air filters, air dryer, flow control, and
electrical components. Removable, soundproofed panels provide easy access to the base
unit’s internal component for maintenance or service. The base unit cabinet is supported by
four, heavy duty, full-swivel, lockable casters. Each frame corner will accept a leveler, which
may be purchased separately.
The flexible air delivery assembly is a well-insulated hose connecting the base unit cabinet to
the shroud (or customer specific test chamber). It holds the main airline, purge airline, air
heater, electrical power wires, and thermocouple leads. For improved reliability, no liquid or
gas refrigerant lines are located inside this assembly.

Description of Equipment
The THJ80 is an air temperature forcing system for thermal testing electronic components. It
is available in the following configurations:
THJ80 -80°C to 225°C
1 208 - 230V @ 60Hz / 200V @ 50Hz
2 220 - 230V @ 50Hz
1 Without holding arm
2 Arm with pneumatic head (up/down)
3 Motorized arm
2 RS232 / GPIB
Figure 1 shows a typical thermal test fixture layout. The insulated shroud prevents ambient
air entrainment, creating a well-defined, repeatable heat transfer environment. The shroud is
usually lowered on to the test fixture with the airflow centered on the DUT. Silicone sponge
insulation is commonly used to thermally isolate the DUT from supporting surface. Although
this configuration is the most popular, the ThermoJet can be adapted to test circuit boards
and a wide range of electronic assembly shapes and sizes. A broad range of standard and
custom enclosures are offered by FTS for this purpose.

System Features
The THJ80 ThermoJet includes the following standard features:
•High capacity, reliable, self-contained, two-stage mechanical refrigeration.
•Wide temperature range that covers most military, industrial, automotive, and commercial
testing requirements.
•Adjustable air flow between 5 and 20 SCFM, in 1 SCFM increments.
•Rapid cycling between temperature extremes.
•Internal thermocouple for air temperature control and monitoring.
•External thermocouple for closed loop DUT temperature control.
•DUT controller auto-tuning.
•Up to 49 eight-step ramp soak recipes.
•Alphanumeric recipe names for easy storage and retrieval.
•Data logging.
•Built-in safety features such as a low air flow safety, an Emergency Mechanical Off button,
and a resettable circuit breaker.
•Easy to change, quick-release shroud with silicone sponge seal to isolate DUT from ambient
environment.
•Caster-mounted for easy maneuverability.
•Compact design that minimizes floor space requirements.
System Specifications
Temperature range: -80°C to 225°C
Temperature accuracy: +/- 0.1 °C
Temperature stability: +/- 0.5 °C
Temperature settablility: 0.1°C
Temperature indication: 0.1°C
Outlet Flow: 5 to 20 SCFM

System Options and Accessories
The standard THJ80 comes equipped with a holding arm and pneumatic lift to support the air
delivery assembly, and automatically raise or lower the shroud. The no-arm option comes
with a cradle to hold the nozzle when the arm assembly is not required. See page 18 for
instructions on operation of the motorized arm option.
The system PLC controls all aspects of the temperature testing. FTS designed the control
algorithms and features specifically for the THJ80 to provide an easy-to-learn, user-friendly
operating environment through the touch screen while still providing the flexibility of remote
access and data logging.
