4. Simple operation

Simple operation: the touch screen controller displays Chinese menu bar and is easy to operate;

Host computer: optional remote monitoring computer, the control system realizes redundant control and remote monitoring;

Using a high-precision temperature sensor, the measurement accuracy is high and the drift is small.

The compressor suction and exhaust pressure is displayed in real time for easy inspection and maintenance; (optional function).

The internal silencer of the unit and the bottom vibration reduction design reduce the transmission of vibration and noise.

The Test Chamber can design the test interface according to user requirements.

5. Complete functions

Complete test functions: high/low temperature constant temperature test, high-low temperature cycle test.

It has complete functions such as remote control of the host computer and dry air purging (optional), making it easy for users to choose according to the situation.

6. Easy maintenance   

Self-diagnosis: The control system has a self-diagnosis function. When overtemperature, compressor overpressure, overload, fan overload and other faults occur, the controller will display the cause of the fault in Chinese and give detailed solutions;

Maintenance: Install a water filter in front of the condenser to facilitate regular cleaning and prevent the condenser from being clogged, causing a reduction in cooling rate or even over-pressure protection shutdown;

History records: Both the touch screen and the optional PC display interface can view temperature history records and alarm records.

2. Relevant standards

3. Box structure

The Test Chamber is composed of four major parts: the insulation box, the refrigeration unit, the air supply device, the control and safety protection system. It adopts an integral design and can be used after it is installed on site and connected to the power supply.

1.1 Cabinet

The box body adopts an overall upper and lower structure, with the working room at the upper part and the unit system at the lower part.

The side walls of the thermal insulation box equipment are in order from the inside to the outside: stainless steel inner wall—external reinforcement—insulation material layer—decorative shell

1.2 Shell

Advanced hot and cold plate nano paint

1.3 Insulation layer

PU (polyurethane) foam + ultra-fine centrifugal glass wool composite insulation layer with high temperature resistance and suitable thermal insulation effect, thickness 100mm.

1.4 Inner wall

The inner wall of the box is made of 1.0mm SUS304/2B stainless steel plate, and all seams are TIG welded continuously to ensure that there will be no leakage after long-term testing.

The outer wall of the inner box is welded and the main positions are reinforced.

Drainage holes are designed on the inner wall bottom plate to drain the condensed water in the box out of the box.

1.5 box bottom

The channel steel at the bottom of the box is welded and formed, with a load-bearing capacity of ≥100kg/m².

Cabinet layout

Directly in front of the upper part of the Test Chamber is the door of the box, and behind the box is the air-conditioning air supply system.

Air conditioning supply

Side air supply: The air conditioning box is at the rear of the studio, with a circulating fan, heater, copper tube aluminum fin evaporator, humidifier, etc. installed inside.

A 0.1HP stainless steel long-axis motor is installed on the top of the box, and a stainless steel centrifugal fan impeller is installed on the top of the air-conditioning box. The air is evenly supplied through the air outlet baffle fixed inside the volute to meet the temperature uniformity requirements.

door

Single hinge anti-collision door (left hinge, right handle), door opening size 1000W×1000H mm, rotating hinge can ensure that the door opening angle is not less than 120°;

The door hinges adopt reinforced hinges to ensure free opening and closing.

An anti-frost electric heating belt is installed on the inner edge of the door, and the control system automatically turns on the heating and defrosting according to the temperature of the studio.

Observation window

A set of multi-layer laminated glass observation windows with a viewing area of ​​300×400 is installed on the door. When the studio temperature is lower than the ambient temperature, the controller automatically turns on the defogging function of the observation window.

The observation window is composed of pressure-resistant tempered glass + multi-layer hollow electric heating frost-proof glass.

The electric anti-frost glass is the most advanced conductive coated glass in CHINA. This observation window has the advantages of high light transmittance, good heat insulation effect, and no resistance wire on the glass surface to affect the observation. When the studio temperature is lower than the ambient temperature, the system automatically Turn on the defogging function of the observation window to ensure clear observation under any Operating Conditions.

illumination

There is a set of 9W lighting fixtures built into the observation window to ensure that the specimens in the box can be clearly observed under any Operating Conditions.

test hole

One Φ50mm test hole is installed on the left side of the box, located in the center (customer can specify)

Control cabinet
