• Enthalpy core
Application

Suitable for very large residential or small commercial applications, the compact SER 3204D comes with access panels on both sides of the unit for installation versatility.

How it works

The SER 3204D unit brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. The enthalpic core at the center of the unit transfers heat and moisture from the incoming air to the outgoing air that was cooled and dried by the building's air conditioner.

When it is warm and humid outside and the indoors are cooled and dehumidified already, the ERV pre-cools the fresh incoming air and transfers a portion of the incoming humidity into the exhaust air, reducing the ventilation load. Reducing the load on the homes air conditioner, saves on cooling costs. This unit is designed for warmer, humid climates with longer cooling seasons.

Defrost cycle

The unit has a built-in defrost mechanism that activates at 23°F in order to prevent the energy transfer core from freezing. Also included are a condensation drain pan & spout.

Dimensional information is in inches (mm)

Fans

Two (2) factory-balanced fans with backward curved blades. Motors come with permanently lubricated, sealed ball-bearings to guarantee long life and maintenance-free operation.

Energy Recovery Core 

Two (2) AHRI certified core made from water vapor transport durable polymer membrane that is highly permeable to humidity. The ERV core is freeze tolerant and water washable. Core dimensions are 12” x 12” (305 x 305 mm) with a 12” (305 mm) depth.

Frost Control

A preset frost control sequence is activated at an outdoor air temperature of 23°F (-5°C) and lower. During the defrost sequence, the supply blower shuts down & the exhaust blower switches into high speed to maximize the effectiveness of the defrost strategy. The unit then returns to normal operation, and continues cycle.
