Each unit now has three copper panels instead of two and a newly designed heating chamber. Multiple copper fins have been added to one of the panels in the unit to increase copper surface area by more than 300% compared to the previous CZ Infrared™ models manufactured by Well Electronics. The copper fins blend the infrared radiation being emitted from the infrared tubes into a more uniform pattern, producing a strong infrared heat pattern. By modifying the internal dynamics in this way, CZ Infrared™ BLUE EDITION heaters maintain all the benefits that the prior heater had but simultaneously eliminate the drag to airflow caused by the coil in the previous design. More copper surface area means more heat generated at the targeted far infrared heat frequency needed to produce optimal therapeutic results. This again contributes to the 4% efficiency increase over last year’s model. The copper diffuser/fins enhance the production of negative ions. This new configuration not only increases the overall amount of heat produced but also enhances negatively charged, ionized water molecules which travel rapidly across the room to penetrate the objects in the room.
