Product Description Step-in Low Temperature Damp Heat Test Chamber Walk-in Cryogenic Humidity Environmental TesterProduct DescriptionProduct Features1. Feature IntroductionThe combined walk-in constant temperature and humidity chamber provides the industry with temperature and humidity environmental tests for large parts, semi-finished products, and finished products, such as computer terminals and automotive components. The constant temperature and humidity system is mainly composed of a control panel, a power distribution panel, thermal insulation panels, a blower, a heater, a humidifier, and a refrigerator. The main specifications can be divided into 4 standard indoor sizes and 24 different condition test specifications.2. With Multiple Expansion FunctionsIt can display SV and PV curves simultaneously, and can be freely switched between Chinese and English. The external USB port can be directly connected to a printer to realize local data curve printing, which is convenient and fast without the need to connect to another computer. (The compatibility of the printer needs to be considered). Without any converter, it can be connected to the computer local area network through an RJ45 standard communication network cable, which is convenient for remote monitoring and supports multi-machine control and management when connected online simultaneously. (Requires a computer to be connected). Regarding the uniformity characteristics of temperature and humidity distribution, a multi-vane blower is used to provide a strong air supply circulation, avoiding any dead corners and making the indoor temperature distribution uniform.

Sum UpThis equipment is applicable to reliability tests simulating environmental conditions such as high and low temperature constant, gradual change, sudden change or damp heat tests for various electrical and electronic products, other products, components and materials. The high and low temperature and damp heat test chamber of MENTEK is designed and manufactured in accordance with the international standards GB/T10586-2009 and GB/T10592-2008.The equipment meets the following standardsGB/T2423.1-2008 Test A: Low TemperatureGB/T2423.2-2008 Test B: High Temperature (Partially)GB/T2423.3-2006 Test C: ab Constant Damp HeatGB/T2423.4-2008 Test Db: Changeable Damp HeatGB/T2423.34-2012 Test Z/AD: Combined Temperature and Humidity Test or Other Temperature and Humidity Tests within the Performance Range of the Equipment Structure of the Test ChamberThe whole test chamber has a prefabricated assembly structure, and a transition room and an observation room can be configured as required. The structure of the chamber body has excellent corrosion resistance and high seismic resistance, and it will not deform. It is convenient for reinstallation, disassembly and construction.Sheet Metal MaterialsThe outer shell of the test chamber is made of powder-sprayed galvanized colored steel plate, and the inner chamber is all made of SUS304# stainless steel plate.Thermal InsulationThere is a thermal insulation interlayer consisting of a rigid polyurethane foam with a thickness of at least 10 cm plus glass wool. The PARKlN combination is adopted around the chamber plates to increase the airtightness of the chamber plates. It has an excellent moisture-proof function, and the density of the PU foam reaches the international standard, ensuring excellent thermal insulation performance.Chamber DoorThe double safety anti-freezing door can prevent accidents and ensure the safety of the operators inside the chamber.Air Supply Circulation in the Test SpaceThe mature air supply system employs a multi-blade aluminum impeller that can withstand high and low temperatures. It is driven by a motor to supply air through the upper louver and return air from the lower side. The uniformity within the temperature range of -60°C to 100°C is less than 2°C (distributed according to the international 10-point standard).Heating and Humidity System(The heater uses finned alloy electric heating tubes with a long service life.)HumidifierIt adopts a humidifying cylinder (boiler method) for humidification. Compared with the traditional surface humidification (water tray method), it has a faster speed, higher control accuracy, and there will be no contamination from water - related impurities inside the chamber. It has good low - humidity performance and is convenient to clean. The humidifying tube uses a full - stainless - steel seamless sleeve with insulation greater than 50 MΩ, and is equipped with an anti - dry - burning controller.Water Consumption and Energy SavingIt is standardly equipped with an RO pure water filtration device for real - time water replenishment, eliminating the need for manual water addition. The humidity is precisely dehumidified and controlled in three zones to save water consumption. For high - temperature and high - humidity conditions such as 70°C and 85%RH, the refrigeration and dehumidification system is designed to be turned off, greatly reducing water consumption.Feature IntroductionThe combined walk - in constant temperature and humidity chamber provides the industry with temperature and humidity environmental testing for large - scale parts, semi - finished products, and finished products, such as computer terminals and automotive components. The constant temperature and humidity chamber is mainly composed of a control panel, a power distribution panel, insulated storage panels, a blower, a heater, a humidifier, and a refrigerator. Its main specifications can be divided into 4 standard indoor sizes and 24 different test specifications under various conditions.With Multiple Expansion Functions- It can simultaneously display SV and PV curves and allows for free switching between Chinese and English. The externally reserved USB port can be directly connected to a printer to achieve local data curve printing. It is convenient and fast without the need to connect an additional computer. (Printer compatibility needs to be considered.)- Without any converter, it can be connected to a computer local area network using the RJ45 standard network cable for communication, facilitating remote monitoring. It supports simultaneous multi - machine control and management when connected online. (A computer is required for connection.)Uniformity of Temperature and Humidity DistributionIt utilizes a multi - blade blower for a powerful air - supply circulation, avoiding any dead corners and ensuring uniform distribution of temperature and humidity inside the chamber.Complete Safety Protection DeviceIn case of an abnormal situation, the control screen will automatically display the fault status, cut off the power switch, and provide troubleshooting methods.Optional Ultra - Low Humidity RangeAn optional chemical rotary adsorption dehumidifier can be used to achieve an ultra - low temperature and low - humidity area. As shown in the schematic diagram, the refrigeration system is used for dehumidification by freezing (the air inside the chamber passes through an evaporator below the dew - point temperature, causing water to precipitate). The ultra - low humidity area is assisted in dehumidification by an external rotary chemical dehumidifier, such as reaching a condition of 10°C and 10% RH. The Munters rotary dehumidifier, a globally leading brand, is selected, ensuring reliable performance!Company ProfileCertificationsShip to Client's Factory Our PartnersPackaging & Shipping
