Precision Level Control: Float Switches and Sensors

Accurate liquid level management is critical for preventing compressor slugging and ensuring efficient evaporator performance. Stellar provides national sourcing for industry-standard level controls, including mechanical float switches and electronic level sensors from leading brands like Hansen, Phillips, and Danfoss. Whether you are managing oil recovery or high-level alarms in a surge drum, our sensing solutions provide the rugged reliability needed to thrive in harsh, high-pressure environments. We stock both complete assemblies and replacement internal kits to ensure your level management remains precise and responsive.

Dynamic Monitoring: Pressure and Temperature Transducers

In an automated refrigeration system, transducers are the primary eyes and ears of your PLC. Stellar offers a wide array of industrial-grade pressure and temperature transducers designed for rapid response and long-term stability. These devices convert physical system vitals into the electronic signals required for advanced capacity control and leak detection. By sourcing high-accuracy sensors from manufacturers like Danfoss and Johnson Controls, we help you maintain the tight operating envelopes necessary for regulatory compliance and maximum energy efficiency.

System Automation: Defrost Timers and Sequencers

The efficiency of your "cold side" depends on the precise timing of defrost cycles and system sequencing. Stellar provides the specialized timing controls and electrical sequencers necessary to manage fan delays, heater cycles, and valve positioning. From simple mechanical defrost timers to advanced solid-state sequencers, we provide the components that prevent ice buildup and ensure consistent temperature control for your inventory. By maintaining a reliable supply of these high-wear electrical parts, we empower your maintenance team to perform scheduled swaps before a component failure impacts your facility's bottom line.
