DESCRIPTION

225L Laboratory Fast Thermal Test Chamber


The thermal testing system is built based on the thermal test requirement UN 38.3.4.2 of Lithium-ion battery testing requirements of UN manual of tests and criteria. An observation window is mounted on the front panel to monitor the real-time status of recharge batteries. The draining system could easily collect unexpected liquids.


Main Features

1.The constant temperature and humidity test box is mainly composed of control panel, distribution panel, insulation layer, air supply fan, heater, humidifier and refrigeration unit. The main specifications can be divided into 6 standard sizes and 10 specifications under different conditions.

2.The controller can be connected to the computer through LAN interface. Users can design programs on the computer screen, collect test data and records, call program execution, remote control machine switch and other functions.

3.The use of multi-wing air supply fan strong air circulation, to avoid any dead angle, so that indoor temperature and humidity distribution is uniform.

4.Complete safety protection device, if abnormal conditions occur, the controller screen will automatically display the fault status, cut off the power switch, and provide troubleshooting methods.

Working noise

A sound level is less than 75 dB (A) (measured in a soundproof room with 25 C ambient temperature and less echo; measured the average value of 8 points by A weighting; measured the level of each test point is 1 metre from the noise source and the height is 1 metre from the ground).

B.Machine Structure

Material of inner and outer boxes

SUS # 304

Outer box light source

High brightness lamp

Structural design of stratosphere

Effective avoidance of condensation at the top of the box

Observation Window

Observation sample use (W*L 28*35 cm)

Anti-sweat design of windows

Electrical heating device to prevent condensation of water and gas (40 W)

Test Holes

 

Can be used for connect external test power cord and signal (diameter 50 mm)

Machine pulley

Pulleys are movable and positioned with strong bolts (200Kg/wheel)

Insulation Layer

Rigid polyurethane foam

(its advantages are:

1. High efficiency and energy saving, seamless after filling, strong bonding after curing.

2. Seismic and compressive resistance, no cracking, no decay, no falling off after solidification.

3. It has ultra-low temperature heat conductivity, weather resistance and heat preservation.

4. High efficiency insulation, sound insulation, waterproof and moisture-proof after curing.

5. waterproof performance is good, because the foam hole is closed, the sealing rate is 95%, and the rainwater will not permeate through the hole.

Inner rack

Movable adjustable grids and two stainless steel strip grids (5.0 cm per grille)

 Box door

 

Double-channel heat insulation and tight gas to effectively isolate external temperature leakage

C.Safety Protection System

Leakage/Surge Protection

2. Temperature/Humidity Sensor→ circuit break or short circuit (+/- OVER)

3. Layer 1 high/low temperature over-temperature protection → Settings for operation control high and low temperature over-temperature protection

Fault Detection and Control Interface(Automatic Detection and Protection Device for External Faults)

1. High Temperature Overtemperature Protection of the Second Layer→Electronic high temperature overtemperature protection device

2. Layer 3 High Temperature Overtemperature Protection→High temperature overtemperature protection device

3. Protection of water-cut incineration→Humidity water cut-off protection and electric heat water cut-off air incineration protection

4. Compressor protection→Refrigerant pressure protection and overload protection.

5. Extended Protective Device→Reserve two sets of fault detection input expansion protection devices for use.

Fault Abnormal Protection

Cut off control power supply and fault reason indication and alarm output signal when abnormal fault occurs.

Active Water Shortage Indicator

Initiative prompt for lack of water on machine.
