BWT AQA therm HRC – hardness-reducing cartridge

The AQA therm HRC softens water for filling and topping-up heating systems, which acts as a form of heat transfer and obtains maximum performance from modern water-based heating systems. Only then can you achieve optimum energy efficiency and operational reliability.

Treated water has altered corrosion chemical parameters, and it is recommended that the heating water is adjusted through the use of inhibitors to prevent corrosion.

Warning! Only AQA therm SRC should be installed where aluminium materials are used. Do not use AQA therm HRC with aluminium.

Main features:

  • Hardness-reducing cartridge
  • Standards-compliant softened fill water
  • Capacity of 3 or 14 m³ x °dH
  • Includes two sizes of cartridge
  • Easy-to-use, one-way system, no return required

2 different sizes of cartridge for topping up the heating system with treated water compliant with standards:

  • AQA therm HRC small
  • AQA therm HRC large
