Frequently Asked Questions

What is a sub zero temperature controller?

A sub zero temperature controller is a device that regulates temperature below 0°C in cold storage, freezers, and industrial processes. It uses sensors and control algorithms to maintain a set temperature, preventing freezing damage or ensuring proper preservation. For example, in vaccine storage, it keeps vaccines at -20°C or -70°C as required. Our controllers support various sensor inputs, like PT100 or thermocouples, and offer features like alarms and data logging. They are essential for industries where temperature accuracy is critical. With adjustable setpoints and hysteresis, they provide flexible and reliable temperature management, protecting your valuable products and ensuring compliance with industry standards.
Our sub zero temperature controllers can handle temperatures from -200°C to 400°C, depending on the model and sensor type. For sub-zero applications, typical ranges are -50°C to 0°C, but some models support -200°C for cryogenic uses. The choice depends on your specific process. For instance, the XRKC XMTG-2001 supports -50°C to 400°C with K-type thermocouples. We offer models with different ranges, so you can select the one that matches your needs. If you have a unique requirement, our engineers can customize the controller to hit the exact temperature range and resolution you require, ensuring optimal performance.
Yes, many of our sub zero temperature controllers have dual outputs, allowing them to control both heating and cooling devices. For sub-zero applications, they typically control a cooling unit, but they can also manage a heater for defrosting or temperature stabilization. By using PID control, they switch between outputs based on the error signal, maintaining precise temperature. For example, in an environmental chamber, the controller might activate a heater to prevent overshoot or to maintain a set point during external temperature changes. This dual functionality makes them versatile and cost-effective, reducing the need for separate controllers. You can configure each output with independent setpoints and alarms, giving you full control.
Absolutely. We specialize in OEM/ODM services for sub zero temperature controllers. You can customize the housing design, LED colors, display labels, and even the PCB layout. We can also modify the firmware to include your branding or specific functions. Our in-house R&D team has extensive experience in creating tailored solutions for various industries. From concept to production, we work closely with you to ensure the controller integrates seamlessly with your equipment. We provide samples for validation and support with documentation.
