A refrigeration system is designed to transfer heat from a lower temperature environment to a higher temperature one—essentially cooling the desired area. This process goes against the natural direction of heat flow (which moves from hot to cold), and therefore requires external energy, usually in the form of electricity.

This is made possible through phase changes of a refrigerant gas. The gas is compressed (increasing pressure = heat), then expanded (cooling down) to absorb heat from the surrounding environment (lower temperature = cryotherapy), in a closed cycle. This cycle can also be reversed (cycle inversion) to produce the opposite effect—releasing heat to the environment (raising temperature = thermotherapy).

This mechanism allows for extremely precise temperature control, which is crucial for both the safety and effectiveness of medical cryotherapy.
In Zamar systems, all components work in synergy to cool (or heat) the ZAMAR fluid, which circulates through thermal wraps and exchanges thermal energy with the patient. The temperature can be set between 0°C and 45°C (depending on the model) and remains stable throughout the treatment.

A Note on Efficiency and Power
Refrigeration systems are widely used in commercial and industrial settings due to their high energy efficiency. The average performance coefficient (COP) is around 3:1 meaning for every watt of electricity consumed, 3 watts of thermal output are produced. This allows ZAMAR to offer the most powerful cryotherapy devices on the market.

Zamar allows for precise control of temperature and pressure via an intuitive digital interface. This ensures:

• Safety: treatments stay within safe therapeutic parameters
• Personalization: each patient receives a tailored protocol
• Documentation: parameters can be recorded for clinical monitoring

Zamar technology has been adopted by orthopedic clinics, rehab centers, and professional sports teams for its measurable and consistent benefits.
