Product Introduction

The largest selected dedicated outdoor-air system uses a long multi-section cabinet and a 20-55 ton refrigeration range. It is intended for central ventilation and latent-load control across large clean manufacturing buildings, with multiple compressor stages and high-capacity heating options matched to outdoor design conditions.

Key Features

Central latent-load treatment

The 15000 CFM platform treats a building-scale outdoor-air stream before distribution to multiple controlled zones.

Multi-stage capacity

Several refrigeration stages support load following across a much broader capacity range than the smaller cabinets.

Large accessory envelope

The extended chassis accommodates substantial heating, filtration and control sections for year-round operation.

Customization	Compressor staging, heat source and distribution interfaces can be configured for the intended application and operating environment.

Applications

Large pharmaceutical plants, semiconductor support buildings, central clean manufacturing ventilation and multi-zone healthcare facilities.

Solutions for Your Application

A central ventilation stream varies significantly between occupied and reduced-production periods.Use staged refrigeration and variable fan control to follow the scheduled airflow and moisture load.

The extended cabinet requires careful roof or grade-level coordination.Define structural support, shipping splits, service clearance and duct transitions before final equipment selection.

Available Options

Multi-stage compressors, reheat, electric or hydronic heat, high-grade filtration, energy-recovery integration, redundant controls and remote monitoring interfaces can be selected.
