When every square foot counts, your HVAC choices have a big job to do. Tight corridors, compact restrooms, and high-traffic foyers all demand equipment that performs well—without eating up valuable space. That’s where the IEC STY/STW Vertical Recessed Cabinet Series fits in perfectly. This unit was designed for close quarters, and it’s been proving itself in the field since 1988.
Built for Tight Spots—Since 1988
International Environmental Corporation (IEC) introduced the STY/STW series more than three decades ago. Since then, it’s become a favorite for recessed wall applications in both retrofit and new construction projects.
Contractors and engineers trust it for one simple reason—it consistently delivers solid performance in places other units just can’t fit.
What Makes the STY/STW Stand Out?
✅ Between-the-Stud Installation - Designed to fit snugly between standard wall studs, this unit makes the most of the space you already have—ideal for renovations or small-area applications.
🛠️ Service Made Simple - With a fully removable front panel, your facility team or service techs can easily access all components without dismantling the wall or surrounding finishes.
💨 Powerful Output - Don’t let the size fool you—this unit delivers up to 275 CFM and 6,100 Btuh, enough to comfortably manage conditioning in smaller zones.
🔇 Quiet Operation - Operating as low as 53 dBA, the STY/STW keeps noise levels low, making it a great fit for spaces where peace and quiet matter.
🔧 Three-Speed Flexibility - Whether you’re aiming for a gentle breeze or maximum cooling, the three-speed fan gives you adaptable comfort control.
The Value of Working with IEC
IEC has earned its reputation by building durable, reliable equipment that’s engineered with real-world use in mind. Their commitment to serviceability makes life easier for contractors and maintenance teams, while their rigorous quality standards give engineers peace of mind.
From healthcare and education to hospitality and commercial office spaces, IEC’s fan coils continue to support building performance across the country.
Space Saving Superstar
For projects where square footage is limited but performance can’t be, the IEC STY/STW Vertical Recessed Cabinet Series checks all the boxes. It’s compact, dependable, and easy to maintain—making it a smart fit for today’s space-conscious commercial designs.
