Heil Quaker ICP 1054395 Restrictor Plate

The Heil Quaker ICP 1054395 Restrictor Plate is a critical OEM metering device component designed to regulate refrigerant flow and maintain precise evaporator pressure in compatible air conditioning and heat pump systems. Unlike adjustable thermal expansion valves, this fixed-orifice flow control plate ensures consistent HVAC system performance by managing the pressure drop necessary for efficient phase change. Manufactured to strict ICP specifications, the 1054395 is engineered for high durability in high-pressure environments, preventing common issues like liquid slugging or evaporator freeze-ups. For contractors performing a restrictor plate replacement, this genuine ICP replacement part guarantees factory-standard flow rates and seating, which is essential for maintaining the SEER ratings of the original equipment. Proper installation is vital for ensuring the refrigerant flow regulation matches the compressor's output, particularly in residential split systems where precise subcooling and superheat measurements are required for optimal heat transfer efficiency.

• OEM Precision: Guaranteed compatibility with Heil, Quaker, and Inter City Products (ICP) air handlers and condensers.
• Durable Construction: High-grade materials resist erosion from high-velocity refrigerant flow.
• Fixed Orifice Reliability: Eliminates moving parts found in TXVs for simplified refrigerant metering and lower failure rates.
• Optimized Efficiency: Maintains calibrated pressure drops across the coil for maximum cooling capacity.

Common Questions

How do I know if my restrictor plate needs replacement?
Technicians should check for signs of clogging or debris within the orifice, which often manifests as inconsistent evaporator temperatures or abnormal high-side pressures. If the plate shows signs of physical erosion or scoring on the seating surface, replace it immediately to prevent metering inaccuracies.

Is this part compatible with R-410A systems?
The Heil Quaker ICP 1054395 Restrictor Plate is designed to handle the operating pressures of modern refrigerants, but always verify the specific orifice size against the manufacturer's charging chart for the tonnage of the outdoor unit.

Can I clean a restrictor plate instead of replacing it?
While superficial debris can be removed, any pitting or internal wear to the orifice bore will alter the flow coefficient. For critical HVAC repair, replacing the plate is the only way to ensure the system returns to its design specifications.
