Alco Controls Thermal Expansion Valves (TXVs/TEVs) modulate refrigerant flow into the evaporator coil based on superheat measurement, ensuring maximum cooling efficiency and preventing liquid floodback. Their sensing bulbs and capillary designs react automatically to load changes, maintaining proper refrigerant charge under varying conditions. Installing Alco Controls TXVs enhances system capacity control, reduces energy consumption, and delivers consistent temperature regulation in comfort and process-cooling applications.
