Pusanda High and Low Temperature Alternating Damp Heat Testing Machine

Pusanda High and Low Temperature Alternating Damp Heat Testing MachineCapable of conducting various experiments in different industrial fields, such as product or material testing in multiple industries such as electronics, electrical, automotive, home appliances, chemical, etc. Not only that, it also supports multiple types of tests, such as low temperature tests, high temperature tests, moisture and heat tests, etc. Through these experiments, enterprises or laboratories can not only understand the performance of products in different environments, but also analyze the stability and adaptability of product materials, providing more effective improvement and management solutions for products.

Material of the box

The shell is made of stainless steel plate processed by CNC machine tools, which is easy to clean, resistant to aging, and has the characteristics of durability, wear resistance, corrosion resistance, etc. The inner liner is made of SUS304, 8k mirror stainless steel plate, which is bright, beautiful, and corrosion-resistant.

Insulation material: Polyurethane foam with high-density aluminum silicate fiber cotton. Aluminum silicate fiber cotton has the characteristics of high temperature resistance and low heat transfer coefficient compared to similar glass fiber cotton. 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 hollow tempered glass and double layered laminated conductive film on the inside and outside, which has the advantages of transparency, heat insulation, and is not prone to steam frosting. It is equipped with high-quality lighting, which can assist in observing the test situation inside the test chamber when the light is insufficient.

The internal circulation system adopts a long axis motor that is resistant to high, low, and high humidity, equipped with aluminum multi blade impellers that are resistant to high, low, and high humidity, to achieve forced convection and vertical diffusion circulation, ensuring uniform and constant temperature and humidity in the laboratory.

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, and if the aperture and number of holes need to be increased, they can be requested at the time of ordering).

High quality fixed PU movable wheels are installed at the bottom of the machine, which can easily move and fix the machine.

Temperature controller: 7-inch color LCD touch screen programmable controller, in both Chinese and English, with adjustable backlight function LCD display controller.

Freezing system:

Adopting a fully enclosed French Taikang (or American Gulun compressor) compressor.

Adopting unit or binary low-temperature circuit system design.

Adopting air-cooled single machine compression/air-cooled stacked compression refrigeration method

Adopting environmentally friendly zero DuPont refrigerants from the United States

Heating system;

Finned heat dissipation tube shaped nickel chromium alloy stainless steel electric heater.

Humidification and dehumidification system:

Install an isolated all stainless steel shallow surface evaporative humidifier, which forms wet vapor humidification through heating and detects humidity through a probe;

Adopting evaporator coil dew point temperature laminar contact dehumidification method;

Water supply system:

Concealed water tank for water supply, with a small water pump automatically pumping water into the humidification tank, allowing for the recovery of excess water Water conservation and consumption reduction.

Protection system:

Non fuse protection switch

Compressor overheat, overload, overcurrent protection

High pressure protection of refrigerant

Fan overheat protection

phase sequence protection

overtemperature protection

Machine alarm and automatic shutdown

Pusanda High and Low Temperature Alternating Damp Heat Testing MachineTechnical specifications and parameters:

In order to ensure that the surrounding environment of the test product meets the environmental testing conditions specified in the test specifications, the volume of the test product (W × D × H) cannot exceed 20~35% of the effective working space of the equipment, and it is recommended to choose products that generate heat during testing, which should not exceed 10%. The ratio of the area of the windward fracture of the tested product to the area of the test chamber shall not exceed (35-50)%, and the distance between the outer surface of the tested product and the box wall shall be maintained at least 100-150mm.

The high and low temperature alternating humidity test chamber adopts high-quality equipment and materials, and undergoes meticulous inspection in various stages such as design, research and development, and production to ensure its good quality. Due to its rational design and process, the high and low temperature wet heat test chamber has a long service life and can operate efficiently and stably under different test conditions, ensuring the scientific and reliable results of the experiment.
