Customizable Features

Our makeup air units are fully configurable to meet the specific performance, efficiency, and environmental requirements of your facility. Each system is engineered to deliver precise temperature control, optimal humidity levels, and low operating cost across a wide range of applications.

Cooling Options

Choose from chilled water, DX, or direct and indirect evaporative cooling systems. Evaporative cooling offers a significant energy advantage by cooling air without driving temperatures below the dew point, avoiding unnecessary moisture removal and the need for energy-intensive re-humidification. This allows facilities to maintain comfortable or process-required humidity levels while dramatically reducing cooling energy compared to traditional refrigeration-based air conditioning.

Heating Options

Available heating configurations include hot water, steam, direct or indirect gas, and electric resistance. Systems can be tailored to provide seasonal heating, process heating, or precise temperature control for sensitive environments.

Filtration Options

Multiple filtration stages are available, including pre-filters, high-efficiency filters, HEPA/ULPA, odor control media, and electrostatic precipitation. These options ensure superior indoor air quality and compliance with clean air or process standards.

Cabinet Construction

Units are available in indoor or outdoor-rated cabinet designs, with customizable sizes and configurations to integrate seamlessly into new or existing building systems.

We Prefer Fans Over DX

Fan-based air handling systems provide a more efficient, reliable, and flexible alternative to traditional packaged DX equipment. By using multiple high-efficiency fans with independent control instead of a single large fan and refrigeration-heavy architecture, these systems deliver better performance across a wider range of operating conditions.

Higher Energy Efficiency

Individually controlled fans operate only at the speed and quantity required to meet real-time airflow demand. This maintains peak static efficiency over a wide operating range and avoids the constant high-energy operation common with single-fan DX systems. The result is lower electrical consumption and reduced total operating cost.

Greater Reliability and Redundancy

In a multi-fan system, airflow is maintained even if one fan or motor requires service. The remaining fans automatically compensate, allowing the unit to continue operating without interruption. This built-in redundancy eliminates single points of failure that can shut down conventional DX systems.

Superior Part-Load Performance

Most HVAC systems operate at part load the majority of the time. Fan-based systems excel in these conditions, dynamically adjusting airflow and pressure to match actual building demand instead of cycling compressors on and off at full capacity.

Easier Installation and Retrofit

Modular fan arrays allow for shorter equipment length and more compact cabinet designs, making them ideal for retrofit projects or installations with limited mechanical room space. Single-point power connections and modular components also simplify installation and future expansion.

Simplified Maintenance

Each fan and motor operates independently, isolating any failures to a single component rather than the entire system. This reduces downtime, lowers maintenance risk, and eliminates the need for complex bypass or emergency systems.

High Quality Construction

Our makeup air units are built to deliver long-term reliability in demanding commercial and industrial environments. Every system is manufactured under strict quality control procedures and subjected to rigorous testing to ensure consistent performance, structural integrity, and serviceability throughout its operational life.

Modular System Design

Modular construction allows units to be easily transported, maneuvered into tight spaces, and assembled on site. This design approach reduces installation time, simplifies future expansion, and supports retrofit applications.

Heavy-Duty Structural Frame

Each unit is constructed on an all-welded, tubular steel frame engineered for strength and durability. Integrated lifting brackets provide safe handling during installation and maintenance.

Premium Cabinet Materials

Cabinet construction is available in steel, aluminum, or stainless steel to match environmental conditions and corrosion requirements, ensuring long service life in both indoor and outdoor applications.

Industrial-Grade Finishing

All cabinet panels, roof, base, interior partitions, and doors receive a prefinished powder coating for superior corrosion resistance, durability, and long-term appearance.

Designed for Serviceability

Every system is engineered with accessibility in mind, allowing efficient start-up, adjustment, component replacement, retrofits, and full unit servicing. This reduces downtime and ensures your equipment remains operational and cost-effective throughout its lifecycle.

Engineered for Performance. Built for Value.

Our makeup air units are designed to deliver exceptional performance while maintaining some of the lowest total installed and operating costs in the industry. Each system is fully engineered, factory-built, and rigorously tested off site, then delivered intact and ready for installation — reducing field labor, minimizing risk, and accelerating project schedules.

From concept to commissioning, our engineering team provides full technical support, including system selection, application design, controls integration, and long-term service assistance. Whether your project requires energy optimization, precise humidity control, or a complete fresh-air solution, our makeup air units provide a reliable, cost-effective path to long-term performance.
