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.

HumidityRange	20%~98%R.H.(10%-98% R.H. / 5%-98% R.H ,is a special optional condition, need Dehumidifier)
Analytic Accuracy/ Distribution uniformity of temperature and humidity	0.1°C; 0.1% R.H/±2.0°C; ±3.0% R.H.

A.Testing Parameter

Temperature range	0℃～+150 ℃(Air-cooled type) Can be customized to below 0℃
Humidity range	20%-98% RH (the distribution range is as follows)
The cooling rate (no-load)	About 1℃/min
The heating rate (no load)	About 3℃/min
Temperature stability	±0.5℃
Analytical accuracy of temperature	0.01℃
Precision of humidity control	±2%R.H
Temperature uniformity	±2.0℃

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 (WL 2835 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
