Performance characteristics of aging box LH-50:

The heating airflow method solves the inherent defect of uneven temperature in the original rotary disc type;

The maximum temperature is 300 degrees, with an accuracy of plus or minus 0.5 degrees, and a temperature uniformity of ≤± 1%;

LTDE programmable control system, curve heating, automatic shutdown and startup;

The aging chamber, also known as the aging test chamber, adopts advanced heating airflow methods from abroad to solve the inherent defects of uneven temperature in the original rotary table type. At the same time, it greatly improves the safety of sample placement, and the effective space utilization rate is more than 200% of the original rotary table type. It is suitable for aging adaptability testing of automotive components, electronic components, instruments, capacitors, resistors, rubber components and other materials at high temperatures.

The new aging test chamber adopts LTDE programmable control system, which can perform programmed temperature rise constant temperature rise constant temperature drop standby within the rated temperature range according to work needs. After the operator sets the program, the instrument will work according to the program and automatically shut down (standby) after completion. The instrument has an over temperature automatic power-off protection function and a dual secondary protection system to ensure the safety of the instrument and test piece. Energy saving and environmental protection are advanced aging testing equipment today

Aging box LH-50 detailed information:

Box structure and materials used
● Outer box material: The outer box is made of high-quality cold plate treated with phosphate film salt and sprayed with high-temperature plastic, with a color of computer gray
● Studio materials: Made of stainless steel double-layer inner liner, movable stainless steel electropolished shelf, tempered glass window,
Internal structure: The bottom of the box is equipped with a specially designed heating chamber, a reasonable air duct structure, airflow circulation design, and forced circulation of the fan. The air inside the box is sucked into the heating chamber by the fan motor and flows back into the working room through the air duct from the two sides and the back three side distributed heat dissipation vents, and then enters the heating chamber, repeating the process to achieve a comprehensive three-dimensional heating effect, ensuring that the air inside the box reaches the maximum amplitude and uniformity. Unique geometric cavity clean design, with two shelves inside the box that can be adjusted in height according to user requirements
● Insulation material: high-density glass fiber cotton, filled with insulation layers in the front, back, left, right, upper and lower layers of the box
Sealing material: The box door and the working room are sealed with high temperature resistant silicone rubber sealing strips to ensure the sealing of the working room. The inner panel of the box door is made of environmentally friendly galvanized sheet. A double-layer tempered glass observation window is installed at the position of the box door, which is transparent and insulated, to observe the changes of the samples inside the box. There is a safety ventilation hole on the back of the box
● Temperature measuring port: PT100 sensor enters from the upper back of the box;
● Terminal post: The terminal post for the heating element is located at the lower rear of the box;
Controller: located under the box, with a built-in control system and compensation wires connected to the PT100 sensor
Heating element: stainless steel electric heater;
● Standard packaging: wooden crate

Temperature control system and its characteristics
Temperature measurement: PT100 high-precision sensor;
Control system: LTDE fully automatic programmable instrument, PID regulation, display accuracy of 1 ℃
● Complete set of electrical appliances: using branded contactors, cooling fans, and solid-state relays;
Time system: can set the heating time, control the constant temperature time, and automatically stop the machine when the constant temperature time is reached;
● Over temperature protection: Built in secondary over temperature protection device, dual insurance;
● Operation mode: Full range adjustable constant temperature, constant operation program running

Wind circulation system
The circulating fan is located in the middle of the heating chamber heater inside the box,
Using a long axis fan motor and multi wing aluminum alloy blades, the air inside the working chamber is forcibly sucked into the heating chamber and automatically flows back into the working chamber through the left, right, and back air ducts, repeating the cycle to achieve uniform and stable temperature of the hot air inside the box

Heating system
Stainless steel heater, located in the heating chamber inside the box, controlled by PT100 sensor response system
The stainless steel heater has LTDE automatic instrument with microcomputer calculation control for heating output

safety protection system
