Our Technology

Engineered to be smarter

From skin-level sensors to cloud-connected software, every layer of the system is designed to work as one.

Skin-contact temperature monitoring

Embedded digital KelviTEC™ thermistors measure actual skin temperature—not device temperature—in real time. The result is a continuous feedback loop that keeps treatment accurate and safe.

Precise, rapid temperature control

Thermoelectric technology delivers exact temperatures from 39°F to 108°F and switches between cold and heat in under 15 seconds, delivering true rapid contrast therapy.

No ice, no water to change

Kelvi heats and cools electronically, not with liquid. That means no ice or water to change, no open fluid containers, no mess.

Connected by design

Software and settings update remotely, and clinicians can push custom protocols directly to the patient's device via the Kelvi Clinician App over Bluetooth.

The Kelvi System

Comprehensive thermotherapy therapy in one package

The Kelvi Console and Smart Wrap work together seamlessly to deliver precise, consistent therapy from 39 to 108°F.

Kelvi Pro-e console

The console

The Kelvi Pro-e console is the brain of the system. This portable unit has a simple, interactive display, and controls the temperature, duration, compression, and therapy mode. WiFi and Bluetooth keep the system connected, so clinicians can push protocols directly to the device and software stays current without any effort from the patient.

What People Say

Real results, real recovery

"The Kelvi was definitely a game changer for us. It is incredibly convenient, primarily when it comes to the ability to contrast within seconds without having to add ice or add water."

WNBA Athletic Trainer

"My favorite thing about the Kelvi is that I can contrast — cold and hot. I love that I can adjust the settings any time I want. I play overseas and I've brought my Kelvi with me. Being able to have that flexibility has helped me tremendously."

WNBA Athlete

"Through high school, college, and pro I've used a bunch of different products to help me recover and Kelvi has been especially helpful to help me recover. Super easy to use. The contrast is an awesome feature. I've seen gains in my recovery, recovering faster and I can use it multiple times a day."

NFL Quarterback

"I'm speechless with what this thing can do for you. It is out of this world. When talking about recovery, this is it."

Elite Runner

"Kelvi was a huge part of my recovery after shoulder surgery. I experienced a lot of pain so the long cold treatments were really helpful. I also used heat and contrast when I started physical therapy which helped with stiffness and soreness."

Police Officer

"I've had multiple surgeries and used Kelvi after my last shoulder surgery and noticed a significant improvement in pain and recovery time. I used cold immediately after surgery and contrast for a few months. It was great to not have to worry about adding ice and water like I did with other devices."

USMC Veteran

"I've used the Kelvi as an athletic trainer with my clients across a variety of settings: high level athletes, public safety employees, and my own family. It's great to have a device that can do 3 different types of treatments for extended periods of time. I was really impressed by the technical aspects of the system and how easy it was for my patients to use."
