Product Introduction

The 850 mm plate size expands module width to 300-1200 mm and provides more transfer surface than the compact core. Plate spacing from 2.0-6.0 mm supports different pressure and fouling requirements. A non-silicone seal option is documented at maximum leakage of 0.1% at 400 Pa, making this model relevant where low cross leakage and silicone control are important to clean manufacturing.

Key Features

Medium recovery surface

The larger diagonal increases sensible transfer capacity for commercial clean AHUs.

Low-leakage sealing

A documented non-silicone configuration limits transfer between supply and exhaust streams.

Variable passage geometry

Multiple plate spacings balance pressure drop, cleaning access and exchanger compactness.

Applications

For medium clean manufacturing and healthcare AHUs requiring separated airstream heat recovery with controlled cross leakage.

Solutions for Your Application

Exhaust contaminants can transfer even through a small core leakage path.Use the low-leakage seal, maintain supply-side pressure bias and verify the stream risk before applying recovery.

The exchanger is selected for efficiency but its pressure loss raises fan energy excessively.Optimize plate spacing and face area using the complete annual energy calculation.

Available Options

Specify flows, recovery target, plate gap, width, seal chemistry, leakage limit, bypass, drain, frost control and casing.
