ENVIRONMENT-FRIENDLY REFRIGERANTS

Atmospheric greenhouse effect and ozone depletion caused by refrigerant emissions have led to significant changes in air conditioning and refrigeration industry, as well as to the development of the new, low global warming potential refrigerants.

At Kaltra, we constantly strive for innovation and venture new paths to protect the environment. One of the directions is adapting and using low-GWP refrigerants in our equipment to comply with the latest stringent regulations that aimed to safeguard and protect the environment.

To date, we use eco-friendly refrigerants in many of our products, including water chillers and heat pump equipment, air conditioning systems and condensers.
