OZ Technology Inc. is the exclusive developer of environmentally safe refrigerants HC-12a and HC-22a. HC-12a and HC-22a, are Earth friendly and non-ozone depleting. Scientific analysis and field experience over the last decade have proven HC-12a and HC-22a are compatible replacements for ozone-depleting refrigerants. HC-12a and HC-22a have also proven to be safe and energy efficient.

HC-12a and HC-22a are 100% natural, environmentally friendly and non-toxic. Our products, when properly applied in refrigeration systems have consistantly reduced power bills by 30%-50% and correspondingly help to extend the life of system components.
