York 2EC0401 Single Enthalpy Kit

Description

York 2EC0401 Single Enthalpy Kit Overview

The York 2EC0401 Single Enthalpy Kit is a precision-engineered economizer accessory designed to maximize the energy efficiency of compatible York rooftop HVAC units. By measuring the enthalpy — the combined heat content of temperature and humidity — of outdoor air, this kit enables the economizer to make intelligent decisions about when to use free cooling, reducing mechanical cooling loads and lowering operating costs.

How It Works

Unlike simple dry-bulb economizer controls that rely on temperature alone, an enthalpy-based control accounts for both temperature and moisture content of the outdoor air. The York 2EC0401 Single Enthalpy Kit monitors outdoor air conditions and signals the economizer controller to open or modulate the outdoor air damper only when outside air is truly suitable for free cooling — preventing the introduction of hot, humid air that would increase the system’s cooling burden.

Key Features

• Single enthalpy sensing for outdoor air economizer control
• Designed for use with compatible York rooftop HVAC units and economizer systems
• Measures combined temperature and humidity (enthalpy) of outdoor air
• Helps prevent introduction of high-humidity outdoor air during economizer operation
• Supports energy savings by enabling true free-cooling when conditions are favorable
• OEM York replacement kit for reliable, factory-matched performance
• Straightforward installation into existing York economizer assemblies

Benefits

• Reduces mechanical cooling runtime and associated energy costs
• Protects indoor comfort by avoiding humid outdoor air infiltration
• Extends equipment life by minimizing unnecessary compressor operation
• Ensures economizer compliance with energy codes requiring enthalpy-based control

Application

Ideal for commercial HVAC technicians and building engineers maintaining or upgrading York rooftop units equipped with economizers. The 2EC0401 Single Enthalpy Kit is the correct OEM solution for systems requiring outdoor air enthalpy sensing as part of an integrated economizer control strategy.
