perma NOVA can be used for all applications that are within a temperature range of -20 °C up to +60 °C (-4 °F up to +140 °F). A discharge period of 1 to 12 months can be easily programmed by pushing the selection button on the NOVA control unit. A built-in temperature sensor periodically measures the ambient temperature and the control unit calculates the required gas generation based on this data. This ensures a continuous and controlled discharge. perma NOVA consists of a reusable control unit, a lubricant canister filled with 130 cm³ of grease or oil, and a protection cover.
