Diagraph

Internal chamber with 1.2mm thick SUS#304 high &low temperature

resistance stainless steel. Bottom with 2mm thick #304 stainless

steel, with high strength square tube connection reinforcement , loading capacity with ≥250KG/㎡

Full closed air cooling type compressor

Danfoss evaporating pressure regulating valve (ensures no condensing under long time low temperature high humidity operating).

1) Danfoss electric expansion valve. Refrigerant flow with servo control

2) Features

1.Totally enclosed type design, with step motor driving

2.Very short time recover from full close to full open.

3 High Accuracy, long life expectancy.

4.Liner flow change, wide cooling range.

5.Continuous cooling adjustment, no liquid hammer in refrigerating circuit.

6. Motor and valve integrate, high reliability.

Main Advantages:

1.Realized active control for cooling system, able to adjust output according to different mode and working condition.

2. Make the cooling system reach best cooling capacity in wider working range.

3.Energy saving: electric expansion valve will full range self-adapt +active adapt to adjust cooling capacity output, realize energy saving purpose.

1. Humidification System: use humidifying barrel humidify, higher speed than traditional way, and not produce incrust ant, good low humidity performance, easy cleaning.

2. With inlayed type humidifying tube, insulation resistance larger than 50MΩ,with dry burn, explosion-proof function.

3. Humidifying barrel made with stainless steel, and with water level observation window.

1.Temp. Humidity Curve:

Paperless recording: built in recording procedure, able to store 3 months records (24hour /day). Automatic create temp. humidity documents, display setting value, actual value, cycles, temperature range, time etc with number and graphs, and it can be download with EXCEL format.

2.Interface:

External USB interface: able to connect printer directly or connect with mouse control. (expand to RS232 &RS485 communication interface ).Download the data via flash disk.. 3.Realtime monitoring :

Special control software, able to monitor 1~16 sets controller simultaneously.

4.Sequential control:

2 group sequential output control interface, match with 10 time control mode, able to provide ON/OFF signal output according program settings. For example: specimen power test, power off, time setting etc. The testing power shall connect to the independent power supply system.

5.Fault Display:

16 group fault alarm output, alarm reason and solutions prompt with both English and Chinese Language.

6.Appointment Start :

All the test condition can be preset.

1.Memory recovery:

With power off memory automatic recover function, able to set continue the pre-testing procedure or start new one. Power off time, times will automatic record, easy for evaluation.

2.Password:

3.Able to set multi-layer password, prevent unauthorized non-operator use and change the inner parameters.

1.With specimen anti-condensing, over-temperature protection (also with independent adjustable temperature protector)

2. No fuse protection switch

3. Heater over-temp. Protection switch

4.Compressor over-load, over heating

5. Compressor high low-pressure protection

6. System over current protection device

7. Controller fault self-diagnosis and display function

8. Phase-sequence protection function

1. Environment Temp.: 5℃-35℃;

2.Relative Humidity: ≤85%RH;

3.Atmospheric Pressure:80kPa~106kPa

4.Away from strong vibration source

5.Power source:

5.1 380V AC (±10%),60Hz 3 Ph 4 wires +grounding wire, earthing resistance≤4Ω;

5.2 Electric wire requirements:5 core(4 core 16mm2copper wire+6mm2 copper wire connect grounding wire)1 rope electric wire (4 meters),use 3P+N 20Aelectric leakage switch.

5.3 Specimen power control connector adopt relay contact control method, AC220V,2A ( Contact closing when machine running normally, when machine under stop or fault ,contact switch power turn off ,run into protection state )

6.Frequency: 60Hz

7.Humidifying water: resistant rate≥500MΩ;

8. Environment air quality requirement: without high density powder, easy firing, easy explosive air or powder, away from strong electromagnetic source

9. Avoid test or storage of easy firing, easy explosive, volatilization and corrosive specimens.

10 Standard specimen place requirement:

10.1 Specimen weight less than 80KG/m³

10.2 Whole specimen dimensionless than 2/5 of the chamber inner volume, each layer less the 2/5 area. Otherwise will seriously effect the chamber performance or the normal operation.
