ClimateCraft Custom Air Handlers: Unique Cabinet Construction for Best-in-Class Performance

When it comes to designing HVAC systems for demanding environments, not all air handlers are created equal. That’s why ClimateCraft’s custom air handling units (AHUs) are trusted by engineers, contractors, and building owners nationwide. With innovative cabinet construction, advanced fan systems, and flexible material options, ClimateCraft delivers best-in-class performance designed to meet the toughest project requirements.

Innovative Cabinet Construction

At the heart of every ClimateCraft AHU is its bolted standing seam cabinet design—a smarter alternative to traditional caulked construction. Built to comply with ASHRAE/ANSI Standard 111 with a minimum of Class 5 performance, this gasketed and bolted design ensures:

• Low air leakage for improved energy efficiency

• Reduced cabinet sweating for better durability

• Best-in-class low-leakage performance with integrated air seals

• Easy maintenance with removable panels and bolted seams

By eliminating caulking, ClimateCraft units maintain performance over time, reducing both energy costs and maintenance headaches.

The Right Material for the Right Application

Every building is different—and so are the environmental challenges it faces. ClimateCraft AHUs are available in a range of cabinet materials to withstand harsh or corrosive conditions:

• Galvanized or painted steel for standard applications

• Marine-grade aluminum for coastal environments

• Stainless steel for industrial or corrosive airstreams

This flexibility ensures your system is engineered to perform reliably, no matter the application.

Building on a Strong Base

Durability starts from the ground up. ClimateCraft air handlers are constructed on welded structural steel bases ranging from 2x5" to 2x12" with supports no more than 24" apart. Bases are available in:

• Epoxy-painted carbon steel

• 304 stainless steel (unpainted, corrosion-resistant)

• Aluminum for weight-sensitive or corrosion-prone applications

This robust foundation ensures structural integrity and long service life—even in the most challenging conditions.

FanMatrix™ Fan Systems and Arrays

ClimateCraft’s FanMatrix™ technology takes fan arrays to the next level, providing redundancy, energy efficiency, and quieter operation. With multiple direct-drive fans, FanMatrix delivers:

• Redundancy to minimize downtime in critical applications

• Optimized airflow with smaller fans for reduced cabinet footprint

• Improved acoustics with flexible fan sizing and speed control

• Reduced maintenance thanks to direct-drive design and replaceable components

For applications up to 20,000 CFM, the compact FanMatrix option offers the same benefits in a smaller, lighter package—ideal for retrofit or space-constrained projects.

Features and Benefits

• Zero harmonic vibration design eliminates drive lockout bands, extending motor life

• Inertia base fan structure prevents vibration transfer through the building

• 5-Year Motor Warranty for long-term reliability

• Optimized fan quantity for efficiency and redundancy with fewer moving parts

• Easy maintenance with replaceable wheels and motors without dismantling the tower

• Optional motor winch for safe and simple service access

BalanceStream® Technology

For even greater efficiency, ClimateCraft integrates BalanceStream® technology into FanMatrix arrays. This simple yet powerful innovation features only one moving part—a spring-actuated inlet cone that:

• Eliminates backdraft dampers with automatic shut-off in case of failure

• Reduces system instability by preventing fan surge

• Operates efficiently from 10% to 100% of design load

• Improves part-load efficiency, reducing energy use and reheat needs in VAV systems

• Requires virtually no maintenance

With BalanceStream, ClimateCraft AHUs maintain consistent performance while cutting operational costs.
