Product Description
How a Perimeter Induction Unit Works
A perimeter induction unit works on a simple principle. Primary air is supplied to the unit at a set temperature and pressure. As this air passes through a nozzle inside the unit, it induces, or pulls in, room air across a heating or cooling coil. The two air streams mix inside the unit and are delivered back into the space at the temperature the room needs.
Because this process is driven by air velocity and nozzle design rather than a fan or blower, this HVAC induction unit has no moving parts to wear out. That is also why it runs quietly and needs comparatively little maintenance next to a fan coil unit, which depends on a motor and blower wheel that both require regular service.
This mechanical simplicity is part of why induction units have stayed in use since the 1950s, and why many buildings that installed them decades ago are now looking at a replacement induction unit rather than a full HVAC redesign. A modern unit can usually be swapped into the same footprint as the original, without the added ductwork a fan coil retrofit would need.

APPLICATION
Our induction unit is commonly used in office buildings, schools, hotels, high-rise towers, and other commercial spaces where a perimeter zone needs steady heating and cooling. In modern retrofit and new construction projects alike, this perimeter induction unit is increasingly built to work at lower operating pressure while still delivering high capacity output, which keeps energy use down without giving up performance.
Because the induction unit has no moving parts, it runs quietly and needs very little upkeep. It adapts easily to a wide range of conditions and does not carry the added energy load that a conventional fan coil system typically requires. Many buildings today are converting to a perimeter induction unit specifically to hold the right temperature and airflow balance between the perimeter zone and the inner core offices, where heat gain and heat loss patterns are usually very different.
Installation is straightforward, and once in place, this commercial induction unit requires significantly lower maintenance than fan coil systems over its service life. It is also priced to fit within most retrofit budgets and can be built into almost any existing enclosure, which matters when a building was not originally designed around a specific unit size. This makes it a practical replacement induction unit for buildings looking to upgrade aging systems without a full renovation. For more detail on capacities and dimensions, refer to the EB Air induction unit brochure below.
BENEFITS
Benefits of Induction Units
- Lower energy use, since induced air mixing does the work that a powered fan would otherwise need to do
- Quiet operation, with no fan or motor to generate running noise
- Significantly lower maintenance requirements than fan coil systems, with no motor or blower wheel to service
- A compact footprint that fits into most existing perimeter enclosures without structural changes
- A long service life, with many units from decades past still running reliably today
- Consistent heating and cooling for perimeter zones without adding new ductwork
KEY FEATURES
- Works as a floor-mounted induction unit or a ceiling induction unit, with a drain pan available on both configurations
- No moving parts, so operation stays quiet and maintenance requirements stay minimal
- Runs on lower inlet pressure than older-generation units, which lowers energy and operating costs
- Available in low-noise and high-capacity models with a higher induction ratio
- Fits into most existing enclosures, which keeps retrofit costs down
- Offered in vertical, horizontal, and linear induction unit formats to match different building layouts
- Adjustable collars and adjustable base height let the unit be fine-tuned on site
- Long induction unit models available for projects that need a single unit to cover a larger area instead of multiple smaller units

Induction Unit vs Fan Coil Unit
Building owners comparing a perimeter induction unit to a fan coil unit usually come down to two questions: how much maintenance the building can take on, and how much energy the system is going to use over its lifetime.
A fan coil unit relies on a motor and blower wheel to move air, which means moving parts that wear down, filters that need regular changing, and a fan that draws power continuously while it runs. An induction unit skips the fan entirely. It uses the velocity of the primary air supply to induce room air across the coil, so there is no motor to maintain and no blower-related energy drawn at the unit itself.
This is also why induction units have become a common retrofit choice again in commercial towers. A building that already has induction units installed rarely needs new ductwork to bring in a modern replacement unit, while switching to a fan coil system usually does, since fan coils need supply and return ducting that older induction-based buildings were not built with.

FAQs
Q1. What is a perimeter induction unit?
A perimeter induction unit is an HVAC terminal unit installed along the perimeter of a building that uses primary air to induce room air across a heating or cooling coil, delivering conditioned air back into the space without relying on a fan or blower.
Q2. What is the difference between a floor-mounted and a ceiling-mounted induction unit?
A floor-mounted induction unit sits at floor level along the perimeter wall, while a ceiling induction unit is installed overhead. Both are available with a drain pan and are chosen based on the building layout and available space.
Q3. Are induction units quiet?
Yes. Since an induction unit has no moving parts, it operates quietly and does not produce the motor or blower noise that a fan coil unit typically generates.
Q4. How much maintenance does an induction unit need?
Very little compared to a fan coil system. With no motor or blower wheel to service, a well-installed induction unit needs only minimal upkeep, which is part of why many older units are still in service today.
Q5. Can an induction unit replace an existing old unit without extra ductwork?
In most cases, yes. Since the building already has the induction supply infrastructure in place, a new induction unit can usually be fit into the same enclosure without the added ductwork a fan coil retrofit would need.
Q6. What sizes does EB Air’s induction unit come in?
EB Air offers standard length units as well as long and extended length induction units, up to 56 to 77 inches, along with vertical, horizontal, and linear configurations to match different building layouts.
Q7. How does an EB Air induction unit compare to standard units on the market?
EB Air’s induction units use an aerodynamic nozzle design to operate at a lower inlet static pressure than many standard units, which helps reduce fan energy consumption at the air handling unit and can lower sound levels in the space.
Q8. Are induction units suitable for retrofit projects?
Yes. A retrofit induction unit is often the practical choice for older buildings, since it can usually be installed within an existing enclosure and connected to existing building infrastructure, which keeps renovation costs and disruption to a minimum.
