Frequently Asked Questions

1. What temperature ranges are available for these walk-in chambers?
We offer four standard temperature ranges: A (0 to 120℃), B (-20 to 120℃), C (-40 to 120℃), and D (-70 to 120℃).
2. How do you ensure the observation window remains clear?
The chambers use a three-layer vacuum-coated window combined with Philips energy-saving fluorescent lamps, which prevents fogging without needing a wiper.
3. What materials are used for the chamber construction?
The interior is made of high-quality SUS304 stainless steel. The insulation consists of Germany Bayer refractory grade high-strength PU polyurethane foam and ultra-fine glass fiber.
4. Is the electrical system safe from water leaks?
Yes, our design features complete separation of water and electricity. The humidification system pipelines are isolated from the power supply, controller, and circuit boards.
5. Which international standards do these chambers meet?
The equipment complies with various standards including GB/T2423, National Military Standards (GJB150), IEC68-2-14, and EIA364-32 among others.
6. What type of power supply is required for operation?
The standard requirement is AC 380V ± 10%, 50Hz, using a three-phase five-wire system.
