Optional Functions
Optional Functions

Low-temperature mold testing

Uses: Enables the chamber to create controlled low-temperature and humidity conditions for mold cultivation and evaluation of material resistance to fungal growth.

Features
  • The cooling capacity is managed by an electronic expansion valve that improves energy efficiency and keeps power use in check.
  • A top exhaust system that helps limit heat buildup in the surrounding workspace.
  • Precise temperature and humidity control with minimal fluctuation and a broad operating range to suit diverse testing protocols.
  • Standard dual cable ports on each side of the chamber for easy connections when running powered tests.

Condensing method Air-cooled/water-cooled

For air-cooled models, performance specifications are based on an ambient temperature of +25 °C and relative humidity of ≤85% measured with the chamber empty. For water-cooled models, reference conditions are an ambient temperature between +15 °C and +35 °C, relative humidity of ≤85%, and cooling water temperature of ≤+28℃, also measured without test samples inside the chamber.

Start by thinking about the materials you need to test and the exact conditions you plan to recreate. Once you share those details with us, our team can suggest a test chamber that matches your testing process and performance targets.

Yes. To maintain stable operation, it’s important to use purified water with controlled levels of resistivity, conductivity, and total dissolved solids (TDS). This helps avoid mineral buildup and keeps humidity readings accurate.

Of course. If you need official verification, we can arrange calibration reports issued by certified third-party labs to confirm the test chamber’s performance.

Both cooling methods are effective, but your choice depends on your facility layout and utility connections. If you’re unsure which one fits your environment best, our specialists will walk you through the pros and cons of each option.
