Overview
The SDW series walk-in high and low temperature wet heat test chamber is developed for large specimens that cannot enter small-scale testing, and can also be used for batch testing of small products, components, and even materials.
Product Details
SDW series walk-in high and low temperature wet heat test chamberIt is developed for large samples that cannot enter small-scale testing, and can also be used for batch testing of small products, components, and even materials.
The circulating air in the test chamber is used for efficient and stable temperature and humidity regulation, ensuring the accuracy and reproducibility of test results regardless of the shape and type of the test sample.
1SDW series walk-in high and low temperature wet heat test chamberFeatures:
Modular design: flexible combination, easy disassembly and assembly.
Standardized Unit: Designed with exquisite craftsmanship.
Long life, fully welded anti slip flooring.
Low energy consumption: Adopting PID+PWM+VRF (cooling, dehumidification) and PID+SSR (heating, humidification) control technologies, energy consumption is more than 40% lower than traditional control schemes.
● Easy to operate: MV technology realizes automatic control of compressor start stop, which can effectively prevent misoperation caused by setting parameters and greatly reduce the difficulty of operators' work.
IILarge walk-in test chambercomponent:
1. Studio
The studio consists of an insulation box (stainless steel inner wall, PU foam insulation, sprayed outer surface), a gate, a pressure balance device, a drainage device, lead holes, lighting fixtures, etc.
It is recommended to prioritize the models in the specification table. When these types of boxes cannot meet your needs, we can provide customized test boxes.
Thermal insulation box: Priority should be given to selecting a 100mm thick box with a high temperature resistance of 100 ℃; Thickness of 150mm, high temperature resistance of 150 ℃;
2. The gate
Double layer silicone rubber seal, anti frost electric heater installed on the door and door frame, automatic control heating defrosting.
Priority selection of sizes for main door openings: single door 1m wide X2m high and 1.4m wide X2m high
Double door 1.6m wide X2m high and 2m wide X2m high
Lead hole: Available in diameters of 50, 100, and 160mm.
3. Observation window
Multi layer insulated glass observation window 400X500mm, other specifications can be customized.
4. Unit
The unit is installed on the chassis at the rear of the studio, including the refrigeration unit and distribution panel.
The semi enclosed compressor cascade water-cooled unit, environmentally friendly refrigerant, three-dimensional pipeline vibration reduction design, nitrogen protection welding, continuous adjustment of refrigeration and dehumidification capacity from 0-100%, automatic adjustment of gas-liquid bypass, evaporation temperature adjustment and other comprehensive technologies are applied to ensure the efficient and reliable operation of the refrigeration unit.
A set or combination of refrigeration units with 15 specifications of 4-75Hp can meet the needs of any temperature rise and fall rate from 0-15 ℃/min.
5. Air conditioning box
A professionally designed internal circulation air supply system ensures efficient heat exchange in the heat exchanger and stable flow and temperature fields within the working chamber.
The circulating airflow is drawn in from below the air conditioning unit, flows through the coil heat exchanger and heater for cooling and dehumidification, and mixes with the water vapor from the external humidifier to enter the top centrifugal fan. The fan outlet is designed with double-layer louvers
Wind fence ensures that the air flow can be evenly delivered into the working room, thereby ensuring high stability of temperature and humidity.
3、 Advantages:
High strength fully welded anti slip bottom plate, with minimal deformation and long service life.
The gate adopts a sloping locking design, which can ensure good sealing effect of the test chamber even in the climate.
Lock the handle to facilitate opening the door from inside and outside the studio, ensuring the safety needs of personnel.
Low cost operation and maintenance.
Use environmentally friendly materials and refrigerants.
● Wide temperature and humidity range.
1. Control:
The temperature is measured using Ptl00 sensors, and the humidity is measured using Vaisala capacitive humidity sensors.
The SDEl300 control system adopts a 10 'color LCD touch screen human-machine interface, which can use tables and various text processing. The built-in chart program editor can easily complete complex program editing. The program curve can be named in both Chinese and English or with numbers for easy searching. The program curve can be edited on a PC and imported through a USB flash drive or network.
An independent temperature safety protection device with adjustable upper and lower limits.
Configure three color indicator lights and emergency stop switch.
The communication SDEl300 has flexible and diverse communication storage functions. Provide upper computer software for communication via TCP/IP, capable of monitoring up to 16 test chambers simultaneously, with USB interface for storage and serial interface for micro printers.
2. Controller highlights:
● Large capacity: Program capacity of 1000 pieces * 1000 segments.
Record and store the set values, measured values, and sampling time of the test chamber in the memory, with a maximum storage time of ten years.
● Program loop and connection functions.
● Pre order power on function.
Password protection and power-off protection functions.
● Self diagnostic function.
The SDEl300 control system can preset a large number of standardized testing process curves for easy user access.
