Manufacturer Custom AHU

Custom Air Handling Units (AHUs) by ER-Flow

Custom Air Handling Units (AHUs) manufactured by ER-Flow are modular systems available in both knock-down and fully assembled configurations. These units are engineered to provide tailored climate control solutions for industrial, commercial, and mission-critical facilities. Designed to deliver optimal indoor air quality, ER-Flow AHUs supply fresh, clean air while precisely regulating temperature and humidity.

Unlike standard off-the-shelf HVAC systems, ERF units are fully customized to meet specific operational requirements, making them ideal for large-scale facilities, cleanrooms, healthcare institutions, and data centers. Each unit is manufactured to the exact dimensions and performance specifications required by the project, ensuring compliance with all design parameters.

Core Functions of Modern Custom AHUs
ER-Flow custom AHUs perform a range of critical HVAC functions, including:

Heat recovery, air recirculation, or fresh air supply
Heating and cooling to maintain precise environmental conditions
Distribution of conditioned air through duct networks
Air filtration, including fine particulate removal and protection against bacteria and airborne pollutants

Types of Custom AHU Configurations
Custom AHUs are available in a variety of configurations to suit the unique requirements of each facility:

Single-pass AHUs: Designed for conditioning and distributing air within a specific zone or space, providing accurate climate control.

Energy Recovery AHUs: Integrated with rotary or plate heat exchangers, these systems reclaim energy from exhaust air to improve efficiency.

Hygienic AHUs: Built for medical and pharmaceutical environments, featuring HEPA filtration, UV-C disinfection, and antimicrobial coatings.

High-performance industrial AHUs: Engineered for large-scale manufacturing facilities, warehouses, and cleanrooms, offering enhanced airflow management and durability.

Advanced Features of Custom AHUs
Many ER-Flow AHUs include advanced features designed to boost performance and energy efficiency:

Modular design: Facilitates customization, expansion, and seamless integration into existing HVAC infrastructures.

Smart automation: Equipped with advanced controls for real-time monitoring and precise adjustment of indoor air quality parameters.

Applications of Custom-Built AHUs

ER-Flow’s custom AHUs are used across a wide range of industries and environments:

Healthcare: Hospitals, laboratories, and pharmaceutical production facilities.
Data Centers: Precision cooling for server rooms and critical IT infrastructure.
