Custom Indoor AHU


Varying purpose-built solutions

STULZ provides individualized solutions for specific data center and other mission critical applications. Below are custom air handling examples that are currently deployed in enterprise data centers.

Customization

  • Customization through various design options and cooling systems: Direct Expansion, Chilled Water, Direct Adiabatic, Free Cooling

  • Different unit configurations: horizontal and vertical airflow, with and without duct system

  • Ultrasonic Humidification for ducted and room mounted systems

Horizontal AHU

The horizontal AHU, available with direct expansion (DX) and chilled water (CW) cooling,  is designed specifically to meet customer requirements.  A specialized fan wall array ensures uniform airflow while meeting low power consumption requirements.  Counterbalanced fan inlet backdraft dampers minimize air recirculation. 

Modular Split AHU

The modular split AHU is available with DX and CW cooling. A vertical center split allows the modular AHU to fit in service elevators and maneuver within tight spaces.  Its modular design allows easy reassembly and rewireing on-site using minimal labor (via frame and electrical connectors).  The unit can also be deployed and/or operated as a half unit by only utilizing one side, therefore increasing redundancy.

Horizontal Stackable Fan/Coil Unit

Stackable chilled water fan coil unit reduces total footprint while maintaining unit serviceability.  Designed to easily stack units securely.  Electrical connectors provided between stacked units to reduce on-site installation time and cost.

Horizontal Split Sectional AHU

The horizontal split sectional AHU is available with DX and CW cooling.  It is sized and split to fit in a standard freight shipping container for intermodal transportation.  Unit can be easily reassembled and rewired on site using minimal labor (via frame and electrical connectors).  Air discharge sound attenuators provided for low sound applications.

WallFlow

The WallFlow horizontal AHU is based on a highly successful custom design that is deployed in multiple locations. Its standardized design enables shorter delivery times while still offering various options or individual customization.
