Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Inspect wiring connections regularly and ensure terminals remain tight. Keep the transformer clean and dry to prevent moisture damage. Periodically check load levels to avoid overheating and ensure consistent voltage performance.

• Overheating under excessive load.
• Loose terminal connections causing intermittent output.
• Primary/secondary voltage mismatch issues.
• Insulation degradation from moisture or heat exposure.
• Reduced efficiency due to winding wear.
• Core saturation at high load conditions.
