Tenney Compact Junior
These benchtop chambers are well-suited for use in electronic,
military, and pharmaceutical quality assurance and reliability testing,
as well as research testing and production processes. In keeping
with the needs of today's lab, we specifically designed these benchtop
and floor chambers to have a compact exterior, yet an ample interior
workspace to maximize valuable floor space.
Features of Tenney Junior
Benchtop Test Chambers
Construction
- All models feature vapor-tight, continuously
welded stainless steel interiors.
- Structural reinforcement is used at all
critical points.
- A combination of fiberglass and polyurethane insulation surrounds
the temperature chamber to maximize insulating characteristics,
thus ensuring
minimal thermal transfer.
Control Tolerance
- ±0.3°C after stabilization
Control System for Tenney Jr. and TU Jr. Benchtop
Chambers
- The proprietary controller can be used
to manually set the chamber at a given temperature, or it may
be used to
enter, store, and execute a temperature profile.
Benchtop Chambers Control System Features
include:
- The ability to store 8 programs with
16 segments each.
- Programs can be linked together or
looped to create a sequence of up to
121 segments.
- RS-485 communications.
- 2 event outputs which can be
controlled manually, or may be
turned on/off during each segment of
a program.
- Guaranteed soak feature.
- Digital displays for both the chamber
setpoint, and the actual chamber
temperature.
Resolution
- Setpoint and chamber temperature
are displayed with 0.1°C or 0.1°F
resolution.
Sensors
- A platinum RTD sensor measures
temperature in the chamber.
- The sensors provide excellent control and display accuracy with
minimum maintenance.
Refrigeration System
- Tenney Hermeticool®: air-cooled,
readily accessible hermetic system uses
accurately calibrated capillary tubes
rather than mechanical expansion
valves.
- This simplifies the system and reduces the likelihood of leaks.
Heating System
- Low-mass nichrome, open wire heating
elements are used to reduce thermal
lag and provide rapid response to instrument demand.
- The heating elements are isolated from the workspace to reduce
radiant influence on the test item.
Electrical
- All wiring in Tenney temperature chambers complies with NEC.
Electrical components are located in a readily accessible, integral
control
panel.
Conditioning System
- Uniform conditions are assured through
the use of a vertical-down recirculating
conditioning stream.
- The system draws air from the bottom of the workspace, conditions
as required, then discharges the air through a grille at the ceiling
level.
- The compact design of the conditioning plenum allows the test
chambers to offer a larger proportional area of interior volume
to exterior volume than afforded by conventional chambers.
Door
- Since the temperature chamber is continuously welded,
the door remains as the final sealing surface
to maintain atmosphere integrity.
- All doors are equipped with double gaskets that trap air for
the purpose of insulation.
