Heat pump protection kit iSTOP 1 inch KIT108706O

Comprehensive heat pump protection – iSTOP 1 inch set

The iSTOP® set is a ready-made solution for installers and owners of monoblock heat pumps, providing comprehensive protection against the effects of contamination, pressure drops and freezing. It is a convenient package of devices that minimizes the risk of failure and extends the life of the heating system.

The set consists of three key components that complement each other: a dirt separator, a filling valve and two anti-freeze valves. This ensures not only effective protection, but also stable and efficient operation of the entire installation.

Set composition and its functions

• Dirt separator DirtmagPro® 1” (no. 545706): A key element in maintaining the efficiency of the heat pump. It captures mechanical contaminants, including harmful ferromagnetic particles, which, when deposited in the system, restrict flow and reduce heating efficiency. The rotating flange makes it easy to clean the separator.
• Installation filling valve (no. 553640): Maintains optimal pressure in the heating system, automatically replenishing water losses. This simple solution prevents problems related to insufficient pressure, which can lead to reduced performance or heat pump failure.
• Anti-freeze valves 1” (2 pcs, no. 108601): An innovative solution from Caleffi, representing the last line of defense against damage to the heat pump in the event of a power failure during frost. These valves react to a drop in temperature and automatically drain water from the installation, preventing it from freezing and cracking system components.
