Main Features and Buyer Value

Five Working Modes for Daily Recovery

The VU-CTM1 hot cold therapy system supports cold only, heat only, cold and heat alternating, heat and cold alternating, and air wave compression. These modes allow users to choose cooling comfort, warming relaxation, alternating temperature stimulation, or compression support according to different recovery needs.

Cold and Heat Alternating Therapy Design

This ice and heat therapy machine provides deeper cold therapy at about 4°C and stronger heat therapy at about 41°C. The cold and heat alternating mode works with a programmed cycle, helping users experience both cooling and warming effects in one session for joint stiffness, swelling discomfort, or muscle tension care.

Air Compression with 3 Intensity Levels

The hot cold therapy unit includes air wave compression with 3 levels and a pressure range of about 30–70 mmHg. The built-in airbag design offers dynamic pressure support, which may help improve local circulation comfort and reduce swelling feeling during knee, calf, thigh, or shoulder use.

Rechargeable and Portable Structure

The VU-CTM1 hot cold therapy system uses a detachable 18650 lithium battery with 11.1V and 2900mAh capacity. The rechargeable design reduces cable restrictions during use, while the 1.2kg lightweight structure makes it easier for users to move between home, gym, clinic, and travel scenarios.

Comfortable Fit for Multiple Body Areas

This ice and heat therapy machine uses three adjustable Velcro straps to help secure the device comfortably around different body shapes. It can be promoted as a knee massager, shoulder recovery wrap, calf care device, or thigh support product, helping buyers expand one model into multiple sales applications.
