E Series Walk In Type Temperature (& Humidity) Chamber

Overview of Equipment:

Energy-saving challenge

The E Series has a newly designed walk-in type chamber that has ecology in mind.
It features various new technology and designs that reduces power consumption by as much as 60% (compared to conventional models) to save energy and boost performance.

Significant reduction in power consumption
The new refrigeration system controls the refrigeration capacity with high accuracy and achieves significant power savings.
Communication network
It features remote monitoring, data transfer via USB flash drive, e-mail alerts when an abnormality occurs, and more.
Meets your performance requirements
Combined with the ideal air conditioner unit to meet the test area capacity and specimen heat load, this system enables selection of the required model.

E-mail alerts
In the event of an alarm, receive alarm details to a registered e-mail address.
Automatic control in test area
The automatic control system enables operation at maximum capacity to the setting and maintains minimum performance after reaching that setting. The system quickly responds to door operation and heat-generation load fluctuations during testing to always ensure a stable test environment.
Improved temperature and humidity distribution and permissible heat generation load performance
The air circulation system, which provides a smooth air flow, and an improved heat exchange efficiency ensure a more accurate temperature and humidity distribution and enhanced permissible heat generation load.

Energy Saving:

New high-accuracy refrigeration system
(Patent No. 5427211)ESPEC is developing original control systems, such as the wide range refrigerator control system that comprises a DC inverter and electronic expansion valve, and an active map system that controls and operates multiple refrigerators with minimum power consumption. These achieve high performance and wide energy savings.

Equipped with all-weather type LED lamp
(Patent No. 5340985)
LED illumination lights up the entire temperature and humidity control range. Features excellent response when lit up, and the illuminance is 2.5 times and the power consumption is one-fifth that of conventional models.

Frost-free expansion
(Patent No. 5355501)
The system comes standard with a function that automatically defrosts the evaporator simply by setting the time with the instrumentation timer during frost range operation. In addition, the frost-free expansion option uses a low humidity dehumidifying system to ensure a frost-free environment across the entire control range, and it reduces power consumption.
Reduced electrical equipment capacity
With cross output control, the maximum current value is lowered during operation, and the electrical equipment capacity of the test area is reduced. (EBE, EBL, EBR)
