First Company 9-321-53-3 Coil V 3R 18T 18L TXV

Description

The First Company 9-321-53-3 is a V-configuration evaporator coil engineered for reliable performance in fan coil and air handler applications. Built with a 3-row, 18-tube, 18-circuit design, this coil delivers efficient heat transfer and consistent cooling capacity. The integrated Thermostatic Expansion Valve (TXV) provides precise refrigerant metering, optimizing system efficiency and protecting the compressor under varying load conditions.

Key Features

• V-coil (A-coil) configuration for compact, efficient installation
• 3-row coil depth for enhanced heat transfer performance
• 18 tubes and 18 circuits for balanced refrigerant distribution
• Integrated TXV (Thermostatic Expansion Valve) for precise refrigerant flow control
• Designed for use with First Company fan coil and air handler units
• Quality construction for long-lasting, dependable operation

Why Choose a TXV Coil?

A coil equipped with a Thermostatic Expansion Valve automatically adjusts refrigerant flow in response to changing load conditions, maintaining optimal superheat at the coil outlet. This results in improved system efficiency, reduced compressor wear, and more consistent comfort delivery compared to fixed-orifice metering devices.
