Product Introduction

This H2 core uses 1200 mm plates and module widths from 350-1200 mm. Its 90-degree profile envelope is approximately 1697 mm, making it physically distinct from the two smaller units. At 2.0-3.0 mm spacing, documented maximum differential-pressure capability is 1500-1700 Pa depending on the exact build. The large passive core suits central facilities but requires careful transport, casing support and frost management.

Key Features

Large single-core capacity

The 1200 mm diagonal handles central AHU flow without assembling many small exchangers.

High differential option

Tighter-gap constructions provide documented structural pressure capability for separated streams.

Passive operation

No wheel motor, belt or pumped loop is required for sensible heat transfer.

Applications

For large clean-facility air handlers requiring separated supply and exhaust sensible heat recovery without rotating components.

Solutions for Your Application

The 1697 mm envelope cannot pass through the plant access route.Coordinate external casing, lifting path and sectional delivery before manufacture.

A large frosted core blocks exhaust airflow during cold weather.Use bypass, preheat, face-and-bypass or defrost control based on the actual psychrometric frost point.

Available Options

Confirm airflow, profile angle, width, spacing, pressure differential, seal, casing, bypass, drainage, frost protection and lifting.
