The condensate neutralizer CondenSAFE product line from Calefactio offers a quick, clean, and convenient solution. Top lid design provides direct access to the engineering media bag, so no disconnection is required to replace the media. To protect the environment and building components, we have included a 12-month time indicator, so the user knows exactly when to replace the media bags. If they are not changed regularly, your water will continue to pass, but will no longer be treated. It is therefore important to change your media bags every year to protect the drain against corrosion.
