High-demand chiller applications, such as refrigeration units, often face frost buildup. Overworking these systems leads to ice formation, reducing efficiency and increasing maintenance needs. Many units use advanced chiller thermostats, specifically capillary thermostats, to ensure precise refrigeration control and prevent frost.
How a Capillary Thermostat Enhances Refrigeration Control
Stemco capillary thermostats maintain precise temperature control within chiller systems. These thermostats use an external sensor bulb to monitor temperature. When the temperature drops to a set threshold, the thermostat contacts open, shutting down the compressor and preventing further cooling. This action stops frost formation. Once the temperature stabilizes and the frost dissipates, the thermostat contacts close, reactivating the compressor. For more information on our line of thermostats, visit the product page.
Integration of Secondary Chiller Thermostats
Some chiller setups use a secondary thermostat, typically another capillary thermostat, for enhanced efficiency and protection. This secondary thermostat prevents the chiller or compressor from operating under specific conditions. For instance, an air conditioning system may use a secondary thermostat to stop compressor activity when the outdoor temperature falls below 50°F, protecting the equipment from damage and inefficiency.
