Product Features
Wide temperature and humidity range
Supports a wide range of temperature and humidity from -10°C to +80°C (standard). Even at low temperatures and low humidity, the non-frost mechanism allows continuous operation without defrosting. The optional dual chiller unit (installed separately) can be added for operation at temperatures as low as -40°C,
Non-frost range can be extended by adding a non-frost mechanism.
Improved space efficiency
Flattened air conditioning unit expands the effective space in the testing room. Sample placement becomes easier, providing an efficient testing environment.
Easy-to-read interior status display panel
The highly visible display panel shows [TROUBLE], [RUN], and [IN/OUT]. It can be installed on either the left or right side of the door, allowing the user to check the room status at a glance. The [ENTERING] indicator is interlocked with the room lamp, allowing the operator to confirm from the outside that he/she is working inside the test room.
operability
- Intuitive touch panel operation: All settings can be made on ETACOM's touch panel. Highly visible UI.
- Programmed operation functionCondition setting for each step, multiple programs can be linked, and repeat settings can be made.
- Trouble ReviewList of past history of abnormalities and actions taken.
- data managementData downloading via USB memory stick and display of historical graphs are supported, enabling paperless management.
- Auxiliary FunctionsDetailed conditions can be input according to the test, such as: timer, humidification delay, weight setting, etc.
- Flexibility in installation of chiller unitsAir-cooled chiller unit can be installed separately, allowing for a flexible layout and outdoor installation.
- LED internal lighting: Effective for delicate work in the testing room.
Environmentally Friendly
Low GWP refrigerant R-448A
With a GWP value of 1387, it reduces greenhouse gas emissions by approximately 65% compared to conventional R-404A (GWP 3920 tired). It is a non-flammable, non-toxic, inert mixed refrigerant. It avoids the worry of reduced refrigerant supply even after regulation, and maintenance costs can be expected to be reduced for the future.
option
It can be customized with a variety of options that improve functionality and ease of use.
-40°C specification
Low temperature operation of -40°C is possible with the addition of a dual chiller unit.
defrost circuit
Manual hot gas method. Effective when samples are frequently loaded and unloaded under low temperature conditions.
non-frost mechanism
Continuous operation is possible without cooling coil defrosting.
Full ceiling blowout specification
Downflow airflow can be created, enabling operation without direct airflow to the sample.
spare room
Suppresses changes in test room conditions when the door is opened and closed.
water purifier
High test quality can be ensured by additional installation even in environments where only tap water is available. Cartridge type for easy replacement.
Floor Reinforcement Plates
For loading and unloading heavy specimens. Required for surface load of 600 kg/m² or more.
Indicator light change
The "Entering" display can be changed to a temperature/humidity display. Convenient when the door is far from the operation panel.
double swing door
W1400 x H1820 mm. can be added or changed to a standard single door.
measurement hole
Inner diameters of φ54 and φ128 mm are available. Mounting position is negotiable.
control hole
150φ inner diameter and can be operated from the outside. Can be used as a set with observation window.
Entrance/exit ramp platform
Aluminum sloping plate (6 mm thick). Available for single and double doors.
Rotating warning lights
Lights up when trouble occurs and can be checked at a distance.
consent
Damp-proof grounding type. 100V/15A, 200V/20A compatible.
paperless recorder
It can be saved to external media and viewed on a PC.
Door section vinyl curtain
Suppresses changes in the internal environment when doors are opened and closed frequently.
Automatic Power-Outage Recovery Function
Automatic recovery and resumption of testing in the event of power failure. Prevents data loss and condition disruptions during prolonged testing.
RS485 interface
Communication interface for connection to external devices and system integration. Available for test data monitoring and control coordination.
Signal Tower
A device that notifies the user of operating conditions and warnings with a lamp display. Test status can be checked from a distance.
emergency stop switch
Safety switch for immediate shutdown of the device in case of emergency. Contributes to the protection of the operator and the test object.
