CalDensate — Acidic Neutraliser for Combination Boilers
The Problem
Condensing boilers produce water vapour during combustion, the water vapour condenses and latent heat passes into the system. Acidic water known as ‘condensate’, is produced. If the condensate is pumped straight to the drain, it can have a harmful effect on the environment.

The Solution
CalDensate is designed to treat the acidic waste produced by condensing boilers. The tough, non-corrosive, in-line unit is quick and easy to fit. There is no need to dig a condensate trap. CalDensate is so versatile; it can be fitted with all makes of condensing boiler — even those that are situated above ground floor level. The acidic waste from condensing boilers (condensate) damages the environment. Dealing responsibly with condensate is easy with CalDensate.

CalDensate Replaceable Cartridges
The unique replaceable cartridges for CalDensate makes the unit even more environmentally friendly. Replacing the special cartridge does not require the complete replacement of the CalDensate unit and the cartridge only needs to be replaced every 12 months.
Ask for the Densate R cartridge.
Installing CalDensate meets BS6798 and Domestic Heating Guide requirements to discharge condensate safely away from the building.
In less than 2 years, condensing boilers could be adding 50 million litres of PH4 acidic waste to our drains every week.
