AerisGuard Bioactive Multi-Enzyme Coil Cleaner is a professional-grade, concentrated enzymatic cleaner formulated for HVAC and refrigeration evaporator coils. A blend of proteases, lipases, cellulases and amylases digests and removes organic matter — biofilm, grease, dust, microbial residue and other contaminants that build up on coil surfaces.
Removing that build-up restores heat exchange, improves airflow and system efficiency, and prepares the coil for a follow-on protective treatment. This listing is the 200 mL concentrate, which makes 4 litres of cleaning solution at 20:1.
Key Features and Benefits
- Targeted biofilm removal — the multi-enzyme formulation penetrates and digests complex organic deposits, including mould, bacteria, fungi and biofilm, for a deep clean of the coil.
- Coil-safe — described by Aeris as pH neutral and non-caustic, and safe for all metal coil types, including aluminium and copper, without corrosion or surface damage even with repeated applications. The SDS lists the concentrate at pH 7.0–9.5.
- Biodegradable — Aeris describes it as completely biodegradable and safe to wash down the drain.
- System performance — removing build-up restores heat transfer, reduces fan load and can lower energy consumption while improving indoor air quality.
- Prepares coils for long-term protection — removing residual contaminants lets a subsequent bioactive coil treatment adhere effectively and function for up to 12 months.
- Standards — Aeris states the product meets DA19 requirements for maintenance and complies with AS/NZS 3666.4 for microbial control.
Typical Applications
- Cleaning evaporator coils in commercial, industrial and residential HVAC systems.
- Servicing refrigeration coils in cold rooms, chillers and food storage equipment.
- Regular maintenance schedules to prevent microbial growth, biofilm accumulation and efficiency losses.
- The preparation step before applying a bioactive coil protection treatment.
Application Instructions
These steps summarise the Aeris procedure (IFU-001, linked below). Isolate the unit before cleaning and use RCD protection throughout.
- Prepare the area. Contain the work area with plastic sheeting, vacuum away visible dust and debris, and check the drain line is clear — flush it if needed.
- Dilute. Mix the concentrate with warm water at 20:1. Aeris quotes 30–60 °C in the IFU and 40–60 °C on the product sheet. 200 mL makes 4 litres. Use the diluted solution within 24 hours and discard any left over.
- Apply. Spray evenly for full coverage of the coil, starting at the top and working down so the solution penetrates between the fins. Prioritise the most soiled areas, and treat both sides of the coil wherever access allows.
- Dwell. Allow 15–20 minutes, or longer for heavily soiled coils, for the enzymes to break down organic deposits.
- Rinse. Remove loosened debris and residual cleaner. Aeris specifies pressure rinsing at a minimum of 45 °C on direct-expansion refrigerant coils and a maximum of 100 °C on chilled- or hot-water coils, with the lance held at 45° and worked in 300 mm passes until the water runs clear and foaming stops. Keep hot water away from smoke and fire detectors.
- Protect. Once the coil is clean and dry, Aeris recommends its AerisGuard Coil Treatment to establish a bioactive barrier that inhibits mould, bacteria and biofilm regrowth for up to 12 months. Contact CCW for availability.
Application rate
Aeris publishes two figures. The product sheet gives 20 mL per m² for small coils and refers larger coils to the IFU. The IFU gives 3 L of diluted solution per m² of coil face (1.5 L per side for a 1 m² coil, 12 fins per inch, 100 mm deep). Size the job on the IFU figure for anything beyond a small split-system coil, and contact CCW if you need help working out quantities.
Safety
Under its Safety Data Sheet (issued November 2023), the undiluted concentrate is classified as hazardous (Reproductive Toxicity, Category 1B). The diluted in-use solution is not classified as hazardous. It is not classified as dangerous goods for transport.
- Handle the concentrate with nitrile or neoprene gloves and wear eye protection where splashing is likely.
- Use respiratory protection in poorly ventilated areas; the Aeris IFU specifies a P3 half- or full-face mask for coil cleaning.
- Read the SDS before use.

Frequently Asked Questions
How much solution does the 200 mL bottle make?
4 litres, at the 20:1 dilution.
Is it safe on aluminium fins?
Yes. Aeris describes it as non-caustic and safe for all metal coil types, including aluminium and copper, even with repeated use.
Does the coil need rinsing afterwards?
Yes. Aeris’s procedure pressure-rinses the coil after the dwell time until the water runs clear and foaming stops.
How long should it dwell?
15–20 minutes, longer on heavily soiled coils.
Can I mix it up the day before?
No. The diluted solution remains effective for up to 24 hours; discard anything left after that.
When should I use Heavy Duty Cleaner instead?
Where the coil is fouled with heavy grease or oil rather than organic build-up, the alkaline AerisGuard Heavy Duty Cleaner is the stronger option.
