Classic Tenney Series - Wide Range Testing

Classic Tenney Series

The Tenney Classic Series of temperature and humidity test chambers deploys
environmentally friendly technology that uses CFC-free refrigerants. The time­proven mechanical refrigeration systems are available in single or cascade
systems and allow for years of worry-free use.

The Classic Series temperature and humidity test chambers are available in
10, 20, 30, 40, and 64 cubic feet models, all of which are available with
single or cascading refrigeration systems.

Features

• Semi hermetic refrigeration system

• Vertical recirculation conditioning system

• Automatic defrost for door gaskets

• Control tolerance between ±0.3°C and ±2% RH typical after stabilization

• Non-corroding parts on all humidity capable units

• Low water protection

dry bulb range of +20°C or +85°C as limited
by a 3°C dew point. Test data based on 24°C
ambient, sea level, 60 Hz. On 50 Hz or higher
than 24°C, ambient performance may be
reduced. Consult factory regarding any
special cooling requirements.
