What are Environmental Testing Chambers
Environmental testing chambers allow you to create highly controlled and simulated environments to test a product's performance and durability. These chambers are able to simulate temperature, humidity & thermal shock. By permitting rapid changes in the environment, temperature chambers can determine the lifespan & performance of a product.

High efficiency and Stable performance of Scroll Compressor
In the reciprocating compressor, the refrigerant gas leaks from the high pressure to low pressure, creating a top clearance volume. The compressed gas remains here, causing re-expansion and lowering the efficiency. In contract, in the scroll compressor, a sickle-shaped intermediate pressure section is formed between the high pressure and low pressure, so only a slight amount of gas leaks. Furthermore, all compressed refrigerant is discharged. Thus, the volume efficiency at a high pressure ratio is higher than that of the reciprocating compressor. Because of this, compared to the reciprocating compressor, the cooling capacity does not drop even at low temperatures of -40: or in high ambient temperature (Models with scroll compressor mounted).
Stable performance even when ambient temperatures are high
Structure of scroll compressor and fluid injection
When a discharge gas temperature rises in the scroll compressor, discharge gas can be cooled by injecting a part of the liquid refrigerant of the receiver to the middle pressure region of the compressor. Then the motor, refrigerating machine oil become lower than constant temperature, so no decline of coolability will happen, and it is possible to operate efficiently.
Vibration and noise of scroll compressor
The scroll compressor can consecutively perform suction, compression, and discharge in one rotation of the scroll. This design greatly reduces sharp fluctuations of compression torque (rotation power) and produces less vibration and noise in comparison with a reciprocating or rotary type compressor.
Theory of scroll compressor operation
The gas sealed between the sickle-shaped compressed air area formed between the fixed scroll and revolving scroll is compressed toward the center and discharged from the discharge port at the center.
High reliability with simple structure
Trouble with the unit is usually arising from the compressor section. With the scroll compressor, there is no suction or discharge valve, and there are only five main components in the compression mechanism (one-sixth the number compared to Hitachi reciprocating model). This simple structure reduces the risk of troubles (models with scroll compressor mounted unit).
Energy saving performance is improved by inverter control of scroll compressor.
Inverter control of scroll compressor (600W) performs great energy saving effect at all the area of temperature・
temperature/humidity control range.
Improved temperature change rate performance.
Improved the performance of temperature change rate of material temperature control to 15℃/min (EC-25EX Series).
