Since the Covid pandemic, indoor air quality (IAQ) is no longer an afterthought. Facility managers, engineers, and building owners are putting clean, healthy air at the top of their priority lists—alongside energy efficiency, smart controls, and long-term system performance.

At VHF, we’re seeing two technologies consistently come up in these conversations:

✅ UV-C disinfection by Evergreen UV

✅ Variable frequency drives (VFDs) by Invertek Drives

These aren’t just upgrades—they’re foundational tools in modern building design and retrofit projects. Let’s break down why.

What UV Light Actually Does in Your HVAC System

You’ve probably heard that UV lighting improves indoor air quality. But how?

UV-C light:

Kills or inactivates airborne pathogens like viruses, bacteria, and mold
Keeps HVAC coils clean, which improves heat transfer and efficiency
Reduces biofilm buildup, lowering pressure drop and energy usage

Evergreen UV specializes in HVAC-integrated UV-C systems, designed for both air disinfection and surface treatment inside air handlers and ductwork. Their systems are widely used in healthcare, education, office buildings, and public spaces—anywhere IAQ is critical.

The benefits go beyond health:

Less coil fouling = fewer maintenance calls
Cleaner coils = lower fan energy use
Continuous disinfection = peace of mind for occupants

You get a more efficient HVAC system and improved indoor air.

Smarter Fan Control with Invertek Drives

If you're not already using VFDs, you’re likely overventilating—and overpaying for energy.

Variable frequency drives (VFDs) allow you to:

Control fan speed based on real-time demand
Extend equipment life by reducing mechanical wear
Dramatically reduce energy consumption, especially at partial load

Invertek Drives are compact, reliable, and incredibly easy to commission. They’re an ideal fit for:

Retrofit air handlers
Constant volume to variable volume upgrades
New DOAS or demand-controlled ventilation systems

When paired with sensors or a building automation system, these drives help optimize airflow while keeping energy use in check.

The Real Power? Using Both Technologies Together

Here’s where things get exciting:

When you combine UV-C disinfection with variable-speed fan control, you get cleaner, safer air delivered more efficiently and more quietly.

This is especially powerful in applications like:

K–12 schools, where both IAQ and noise levels matter
Healthcare environments, where cleanliness is critical
Office buildings, where occupant confidence affects return-to-work strategies
High-rise residential, where comfort, air quality, and energy cost are all top concerns

Why It Matters

Design trends like DOAS, bipolar ionization, and air quality monitoring are here to stay. But they’re only as effective as the equipment supporting them. That’s where Evergreen UV and Invertek Drives shine.

At VHF, we work with both brands because:

They’re proven in the field
They offer fast lead times and flexible options
They fit the types of buildings we see in the Midwest—existing facilities with real-world challenges

Planning a Project Focused on IAQ or System Efficiency?

Let’s talk about how UV disinfection and VFDs can play a role in your design. Whether you're retrofitting an older school or building a state-of-the-art wellness center, VHF is here to help you size, select, and budget the right mix of equipment.
