The Frick Industrial Refrigeration temperature controller-limiter is a critical safety and operational component designed for heavy-duty industrial cooling environments. Engineering to meet the rigorous standards of global refrigeration, this device serves as both a primary thermostatic controller and a failsafe high-limit safety cutout.

Redundant Safety Protection

• High-Limit Cutout: The limiter function is designed to trip and shut down equipment if temperatures exceed safe operating parameters, preventing catastrophic compressor failure or oil carbonization.
• Manual Reset Requirement: In compliance with safety regulations, once a high-limit trip occurs, the device requires a manual reset by an operator, ensuring the cause of the overheat is investigated.
• Corrosion Resistance: Built to withstand the harsh environments of ammonia-based refrigeration systems, featuring robust housings and chemical-resistant sensing elements.

Precision and Versatility

• Wide Range Settings: Highly adjustable setpoints allow for fine-tuning based on the specific thermal requirements of different refrigerants and lubricants.
• Reliable Switching: Features heavy-duty electrical contacts capable of direct integration into compressor control panels and PLC-based management systems.
• Industrial Legacy: Backed by Frick’s century-long expertise in refrigeration, these units are the standard for reliability in food processing, chemical cooling, and large-scale ice production.

Typical Applications

• Screw and reciprocating compressor discharge temperature monitoring
• Lubricating oil temperature control in large refrigeration skids
• Process fluid temperature regulation in chemical plants
• Industrial-scale walk-in freezers and cold storage facilities
