Description
The POL-EKO SLWN 240 is engineered for high-volume laboratories where preventing sample oxidation is as critical as temperature precision. The “N” in the model name highlights its Nitrogen Blow capability.7 By introducing dry nitrogen into the 245-liter chamber, the system effectively purges oxygen, creating an inert environment that protects sensitive materials from degrading, burning, or changing color at high temperatures.Gas Flow Management:The SLWN 240 is configured to ensure that the nitrogen purge is both effective and measurable:SLWN1 Version: Includes a laboratory rotameter that can be officially calibrated?essential for regulated pharmaceutical and aerospace applications.8SLWN2 Version: Equipped with a technical rotameter (non-calibratable) for standard industrial processes where high-precision certification isn’t required.9Efficient Purging: The system is designed to provide a flow rate capable of replacing the chamber’s volume multiple times per hour, as required by standards like ISO 589:2003 for moisture determination in hard coal.10Forced Air Performance:In a chamber of this size, temperature uniformity is maintained through forced air convection.11 The fan actively circulates the heated nitrogen/gas mixture, ensuring a temperature variation of only 12$pm$2.5?C at 105?C.13 This prevents “dead zones” where gas might stagnate or temperatures might drop, ensuring consistent results for all 10 possible shelf positions.+1Smart Control & Security:Interface: The 4.3″ Smart controller provides a clear overview of parameters.14 It allows for complex multi-segment temperature profiles to automate multi-stage curing or drying processes.15Safety: Built-in Class 2.0 (Smart) or Class 3.1 (Smart PRO) over-temperature protection ensures the unit remains safe even during unattended overnight runs.16Documentation: Integrated USB and LAN ports allow for easy data export, providing a full audit trail of both the temperature and the timing of each run.17Primary Applications:Industrial Electronics: Curing large batches of PCBs and semiconductors in an oxygen-free environment.Chemical Production: Drying large volumes of oxygen-sensitive powders or resins.Fuel & Energy Labs: Moisture analysis in coal and coke (ISO 589) where preventing oxidation is mandatory.18Advanced Materials: Heat treatment of polymers or metals that are prone to oxidative degradation.
