3.7L Viper Evap+ Coil Cleaning solution

The same solution, sized for the whole job

This is the identical Viper Evap+ coil cleaning solution that comes in the 500ml bottle, just in a 3.7 litre drum instead. If you are cleaning more than a handful of units this season, or you know you will be back for more solution anyway, this is the size that makes sense.

Who buys the 3.7L

• Landlords maintaining units across more than one rental property
• Airbnb and short-stay hosts with several systems to keep on top of
• Big households running a ducted system plus one or more split systems
• Small businesses and trades cleaning client units
• Anyone who has worked out they are going to be doing this every year

The maths on it

Litre for litre, the 500ml bottle works out to $79.90 a litre. The 3.7L drum works out to $28.92 a litre. That is roughly 64% less per millilitre for buying the bulk size, before you count the time saved not reordering every couple of units.

How it works

Same formula, same job. It breaks down the biofilm, oil and dust built up on evaporator coils that a plain water rinse leaves behind. Spray it onto the coils, give it time to work, then flush and wipe down as set out in the kit instructions.

Buying the drum on its own assumes you already have the applicator and catchment gear. If you do not, start with a cleaning kit and keep this size in mind for the refill.
