Filter Kits
The filter kits for Noren heat exchangers are designed to screw directly onto Noren heat exchangers and prevent dirt and dust from accumulating in the heat exchanger core.
The reusable aluminum filters are designed to be washed and reused.
The disposable polyethylene filters are designed for use up to twelve months (depending on the amount of dirt and dust in the environment), after which they are discarded and replaced.
Fans
Replacement parts for heat exchanger fans can be requested through our sales department. Standard fans are typically used in applications where there is little to no possibility of exposure to moisture or water.
Universal fans are for damp locations that can be used in various environments. Typically, these have encapsulated motors. Non-standard fans are washdown fans used in applications where the environment is moist.
Gaskets
Noren’s specially designed gaskets allow our heat exchangers to maintain an air tight seal, preventing contamination in the control panel and uphold various UL and NEMA integrity standards. We use high-quality neoprene seals to facilitate this process.
