The Only HVAC Scent System That Energizes The Fan Before Delivering Scent
Every other HVAC scent system on the market has the same blind spot: they pump fragrance oil into ductwork whether the fan is running or not. That means wasted oil, inconsistent scent delivery, and — worst case — oil pooling in idle ducts that creates maintenance headaches and an unpredictable guest experience.
The ScentBeat HVAC Pro Kit eliminates that problem.
Here's how it works: The PowerTend Relay is wired to the HVAC fan circuit and energizes the relay to activate the fan. After the fan has begun moving air sufficiently, the ScentBeat diffuser begins delivering fragrance. When the scent cycle is complete, the fan is kept running for a short periood to ensure full distribution throughout the facility, preventing unwanted scent oil buildup. If the fan isn't running, scent doesn't flow. Period.
It's a simple concept that no one else has put together — and it changes the reliability and economics of commercial scent delivery.
What's in the Kit
- PowerTend Relay — Wired to the HVAC fan circuit to energize the fan relay, acting as the gatekeeper that prevents scent delivery into static ductwork.
- Installation Kit — Required tubing, mounting components, and power cord.
- Sold Separately - ScentBeat Scent Diffuser — ScentBridge's commercial-grade HVAC scent delivery system, designed for inline installation in commercial duct systems.
What You Get at Launch
- Remote Control & Scheduling — Manage the entire system from the IntelliTend app. Set schedules that align with facility hours, occupancy patterns, or event timing.
- System Status at a Glance — See whether the diffuser is running, the fan is energized, and both devices are communicating — all from one dashboard. Know the status before your client calls to ask.
- Dual Wireless Connectivity — The PowerTend Relay communicates to the cloud via WiFi and to local devices via BLE. Add the SecureSend Gateway for standalone cellular connectivity that keeps IoT traffic off the corporate network (requires service plan).
What's Coming Next
- Automatic schedule synchronization between the Relay and diffuser to optimize fan run times and maximize scent coverage
- Power consumption monitoring for the diffuser, enabling usage tracking and service interval planning
- Configurable alerts for system anomalies — fan not running during scheduled hours, diffuser offline, connectivity issues
Why This Matters
For scent service providers, this is a service quality and cost story. No more wasted fragrance oil. No more callbacks because the scent isn't right. No more guessing whether the system is actually running. You get confirmed delivery, remote visibility, and a reason to charge for a premium, managed service.
For facility managers, this is a reliability and control story. You know the system is working because you can see it — not because someone told you it was. Scheduling is automated, status is confirmed, and you're not relying on site visits or vendor check-ins to know what's happening in your ducts.

What makes this different from other HVAC scent systems?
The ScentBeat HVAC Pro Kit is the only commercial scent delivery system that coordinates running the HVAC fan with fragrance delivery, eliminating messy buildup and wasted scent oil. Other systems deliver scent on a schedule or timer regardless of whether the fan is on — leading to wasted oil and inconsistent results.
Who installs this?
The ScentBeat diffuser installs inline in commercial ductwork and the PowerTend Relay is hardwired to the HVAC fan circuit — both should be installed by a qualified HVAC technician or electrician. The PowerTend Plug is plug-and-play.
Does this require WiFi?
The system works over WiFi out of the box. For installations where WiFi isn't available or corporate policy restricts IoT devices on the network, add the SecureSend Gateway (sold separately) for standalone cellular connectivity.
Do I need a subscription?
Basic features — remote on/off, scheduling, and connectivity confirmation — are included on the free Basic tier via WiFi. The Commercial tier adds cellular connectivity and phone support (custom alerts, data history and hierarchy coming soon). The Enterprise tier adds BlueStreak IntelliTend Network Operations Center monitored service with proactive alerting.
Can I monitor multiple locations from one dashboard?
Yes. The IntelliTend platform supports multi-site management. Monitor and control all your ScentBeat HVAC Pro Kit installations from a single dashboard, whether you have two locations or two hundred.
What fragrance oils does the ScentBeat diffuser use?
The ScentBeat system uses ScentBridge fragrance oils. Contact ScentBridge or BlueStreak for fragrance options and refill scheduling.
