What is the safe-operating temperature range for the AEROSTRIP® diffusers?
The maximum operating temperature of the wastewater is 35 °C (95 °F), which is acceptable for all US municipal applications (we have AEROSTRIP® installations in FL, AZ, and CA). The water surrounding the diffuser must never be allowed to freeze. Temperature limits for storage are -5 °C to 40 °C (23°F to 104°F). If the diffusers are to be stored outside at or below freezing temperatures, frost damage must be avoided. UV inhibitors are added to the AEROSTRIP membranes. However, as with all thermoplastic materials, the membrane can be damaged from long-term exposure to UV light. The diffusers should be kept in their shipping crate until they are ready to be installed. Once installed, it is recommended to maintain 1 m (3.3 feet) of water over the diffusers during prolonged idle periods.
