Environmental Test Chambers
Tenney Temperature / Humidity Cycling Chambers |
||
|
Classic Tenney Series Our Classic line of Tenney Series test chambers employ leading edge technology with the most efficient and environmentally friendly test equipment possible. State-of-the art controllers allow precise, effective monitoring and programming of your chamber. An exact blend of insulations ensure efficient chamber operation and maximize floor space by minimizing equipment footprints. Time-proven mechanical refrigeration, in single or cascade systems, allow years of worry-free use. And, environmentally safe CFC-free refrigerants provide the safety you demand. Features

|
| Standard Features 40, 64 Cubic Feet | ||
| CONSTRUCTION All models feature vapor-tight, continuously welded stainless steel interiors. Structural reinforcement is used at all critical points. Through-wall ports are continuously welded. A combination of fiberglass and polyurethane insulation surrounds the chamber to maximize insulating characteristics, thus ensuring minimal thermal transfer. |

CONTROL SYSTEM FOR HUMIDIFIED UNITS
|
||
CONTROL SYSTEM FOR TEMPERATURE-ONLY UNITS Features include:
|
||
| CONTROL TOLERANCE ±0.3°C and ±2% RH typical after stabilization. |
||
| RESOLUTION Setpoint and chamber temperature are displayed with 0.1°C or 0.1°F resolution, and 0.1% RH on humidified units. |
||
| SENSORS A platinum RTD sensor measures temperature. Humidity is measured by an electronic, capacitive sensor that requires no wet wick or water supply. The sensors provide excellent control and display accuracy with minimum maintenance. |

REFRIGERATION SYSTEM
|
||
| HUMIDITY SYSTEM Tenney VaporFlo®: the humidity system is constructed of 100% non-corroding parts and is equipped with its own lowwater protection system. The system operates at atmospheric pressure and is specially vented to prevent unwanted siphoning. |
||
| HEATING SYSTEM Low-mass nichrome, open wire heating elements are used to reduce thermal lag and providerapid response to instrument demand. The heating elements are isolated from the workspace to reduce radiant influence on the test item. The chamber is protected via a fusible link for heater shutdown in the event of high temperature runaway. |
||
| ELECTRICAL All wiring complies with NEC. Circuit breakers are used throughout the electrical system and are located, along with other electrical components, 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 it as required, then dischargesthe air through a grille at the ceiling level. The compact design of the conditioning plenum allows the Tenney Series to offer the largest possible proportional interior to exterior volume. |
