Greenhouses & Plant Growth Chambers: Precise temperature and humidity control is critical for optimal plant growth. TH100 manages both parameters simultaneously with dedicated heating/cooling and humidifying/dehumidifying outputs.
Warehouses & Storage Facilities: Protect sensitive goods – from electronics to pharmaceuticals – by maintaining stable temperature and humidity levels to prevent damage or spoilage.
Clean Rooms & Laboratories: Perfect for environments requiring strict environmental control. Dual-loop monitoring with RS-485 communication enables centralized supervision and data logging.
Food Processing & Cold Storage: Maintain food safety and quality with reliable temperature and humidity regulation. 2 relay outputs allow control of multiple equipment (compressors, heaters, humidifiers, dehumidifiers).
Textile & Printing Industries: Fiber and paper products are highly sensitive to humidity changes. TH100 ensures consistent environmental conditions for quality production.
Mushroom Cultivation Chambers: Different growth stages require specific temperature and humidity profiles. TH100 provides the precise dual-loop control needed for optimal yields.
Livestock & Poultry Houses: Maintain animal comfort and health with proper environmental control, reducing stress and improving productivity.
