Environmental simulation high and low temperature alternating cycle test chamber

Environmental simulation high and low temperature alternating cycle test chamberIt is possible to set the required high and low temperatures, as well as the time required for the required temperature, in the instrument parameters at once. The test chamber will follow the set program to make the test effect closer to the natural climate, simulate a more severe natural climate, and thus increase the reliability of the tested sample.

The outer box is processed and formed by CNC machine tools to ensure accuracy and aesthetic appearance

The equipment casing is made of stainless steel or A3 steel plate and processed by machine tools. It is easy to clean, resistant to aging, and has the characteristics of durability, wear resistance, and corrosion resistance.

The inner liner is made of SUS304, 8k mirror stainless steel plate, which is bright, beautiful, and corrosion-resistant.

Insulation material: high-density aluminum silicate fiber cotton, which has the characteristics of high temperature resistance and low heat transfer coefficient compared to similar glass fiber masks. The insulation thickness is 100mm to ensure that the temperature inside the test room will not be transmitted to the outside of the equipment, making the test temperature more accurate.

Install an observation window at the center of the test chamber door to observe changes in the indoor sample. The observation window is made of three-layer insulated tempered glass with double-layer adhesive on the inside and outside

The composite conductive film has the advantages of transparency, heat insulation, and resistance to steam frosting. It is equipped with high-quality lighting to assist in observing the test conditions inside the test chamber when there is insufficient light.

The internal circulation system adopts Taiwan, China's high temperature and humidity resistant long shaft motor, equipped with high and low temperature resistant aluminum multi wing impeller, to achieve forced convection vertical diffusion circulation, so that the temperature in the laboratory is uniform and constant.

A double-layer high tensile silicone sealing strip that is resistant to high and low temperatures is used between the test chamber door and the box body to ensure the sealing of the testing area. The main door plate is made of stainless steel, which is beautiful, durable, and uses a non reactive door handle, making it easier to operate, durable, and not easily damaged.

The lead test hole (on the left side of the machine) can be used for external testing of power or signal lines (with a diameter of 50mm, one is standard). If the aperture and number of holes need to be increased, they can be specified when ordering. ）

Refrigeration system: Choose fully enclosed French Taikang (or American Gulun) compressors. Adopting air-cooled single machine compression/air-cooled stacked compression refrigeration method.

Heating system: Nickel chromium alloy electric heating heater.

Wind circulation system: using multi wing air supply fans for strong air circulation, avoiding any dead corners, and ensuring uniform temperature distribution in the testing area. The design of air circulation for air outlet and return meets the testing standards for wind pressure and speed, and can quickly stabilize the temperature at the moment of opening the door.

Heating, cooling, and system independence can improve efficiency, reduce testing costs, extend lifespan, and decrease failure rates. The output power of temperature control is calculated by a microcomputer to achieve high precision and efficiency in electricity consumption.

Safety protection system: no fuse switch, anti dry burning device, extreme high and low temperature protection, temperature deviation alarm, compressor overpressure, overload, overcurrent protection, phase loss, reverse phase, short circuit, leakage protection.

Standard configuration:

(1) One large vacuum tempered glass perspective window with embedded heating element.

(2) One test hole with an inner diameter of ￠ 50mm and one foam silicone plug (the diameter and number of holes can be added according to customer requirements).

(3) 2 stainless steel compartments with 8 stainless steel supports.
