Trane MOD1562 RTAA/WA Electronic Expansion Valve (EXV) Module

Description

Trane MOD1562 RTAA/WA EXV Module Overview

The Trane MOD1562 is a factory-engineered Electronic Expansion Valve (EXV) Module designed specifically for Trane RTAA and RTAA/WA series chillers. This module serves as the dedicated control interface for the electronic expansion valve, precisely regulating refrigerant flow into the evaporator to maintain optimal superheat levels and maximize overall chiller efficiency. Replacing a failed or degraded EXV module with a genuine Trane part ensures your chiller operates within factory-specified parameters and protects the integrity of your refrigeration circuit.

Key Features

• OEM Trane replacement module engineered for RTAA and RTAA/WA chiller platforms
• Controls the electronic expansion valve for precise refrigerant metering
• Maintains accurate superheat control to protect compressors and optimize capacity
• Direct drop-in replacement — no field modifications required
• Supports reliable, long-term chiller operation and system uptime
• Genuine Trane quality construction for consistent performance

Application

The MOD1562 is intended for use in Trane RTAA/WA air-cooled and water-cooled scroll chiller units. It is a critical component of the refrigerant circuit control system, working in conjunction with the chiller’s main control board to dynamically adjust expansion valve position based on operating conditions. Proper EXV module function is essential for maintaining system efficiency, preventing liquid floodback, and ensuring stable operation across varying load conditions.

Why Choose a Genuine Trane Replacement?

Using an OEM Trane module like the MOD1562 guarantees compatibility with your existing chiller controls, firmware, and communication protocols. Aftermarket alternatives may not provide the same level of integration, potentially leading to control errors, fault codes, or reduced efficiency. Trust genuine Trane parts to keep your RTAA/WA chiller running at peak performance.
