Product Introduction

This unit uses a side-by-side Z-circuit whose charge and internal geometry favor winter heating recovery while retaining some cooling-season transfer. Half-inch copper tubes sit in a minimum 16-gauge galvanized or stainless frame. The physical circuit differs from the equal bidirectional model and should be oriented for its intended dominant heat-flow direction; reversing the installation can reduce the winter benefit it was selected to provide.

Key Features

Cold-climate optimization

Circuit charge prioritizes heat transfer from winter exhaust to cold outdoor supply air.

Passive sealed tubes

Working fluid circulates inside 1/2 in copper tubes without pumps.

Robust section frame

Galvanized or stainless framing supports the two coil faces across the air-stream partition.

Applications

For cold-climate clean facilities with high winter outdoor-air heating loads and separated exhaust and supply paths.

Solutions for Your Application

The heating-biased circuit is installed backwards relative to winter air temperatures.Mark supply, exhaust and seasonal heat-flow orientation clearly and verify it before commissioning.

Frost develops on the exhaust-side face at low outdoor temperature.Model the frost threshold and provide bypass, preheat or staged airflow control.

Available Options

Confirm winter and summer conditions, rows, circuit orientation, fin spacing, coating, frame alloy, bypass and frost controls.
