- Page 3 CLEANING GUIDE FOR OUTDOOR HEAT EXCHANGERS 1. GENERAL RULES It is strongly recommended to regularly clean coil of the heat exchanger, at least once a year. Insufficiently maintained equipment will have a short life expectancy, compared with an identical equipment with regular routine maintenance. An insufficiently maintained equipment exposed to an aggressive environment, may be quickly deteriorated, even if an appropriate protective treatment has been applied for the manufacturing of equipment.
- Page 4 Adiabatic system Misuse of adiabatic systems can become an aggravating factor in heat exchanger soiling. As a reminder: - Only PROFROID adiabatic supplied systems must be used on PROFROID exchangers. Any other system of misting, spraying or watering is prohibited - The quality of the water must be regularly checked according to the criteria described in our Instruction and Operation Manual (IOM), see specific chapter of the manual.
- Page 5 Cleaning with clean water (low pressure) - For slightly dirty coils, it is also possible to clean with clean water. - Initially clean with a non-metallic brush (soft brush). - Suck the front surfaces with a vacuum cleaner. - After brushing and vacuuming, clean the coil with a jet of water (ideally flat jet). Use clear water at the pressure of the tap water network (3 bar max).
- Page 6 3. HIGH PRESSURE CLEANING – MODERATELY SOILED COILS Turn off the entire unit, and secure the unit against unintentional power-on. Comply with the site's specific safety instructions. Cleaning with a water pressure washer For moderately soiled heat exchangers: wet or oily dust, residues with little clogging,… it is possible to use a pressure washer. - Choose a nozzle to obtain a flat jet (25°) - Before proceeding on the heat exchangers, it is recommended to activate the hose outside of the heat exchangers, then start the cleaning at a distance greater than the minimum distance allowed.
- Page 7 5. HEAT EXCHANGERS WITH HERESITE® COATING Turn off the entire unit, and secure the unit against unintentional power-on. Comply with the site's specific safety instructions. For maintenance on heat exchangers coated with HERESITE® treatment, please refer to SAKAPHEN® INSTRUCTION TECHNIQUE INS/TEC/18 procedure attached below.
