LK 556 AntiFreeze
• Protects heating system from freeze damage
• The valve is maintenance free
• Set includes two AntiFreeze valves and two
insulation pieces
LK 556 AntiFreeze protects your heating system, usually in an
air/water heat pump, if the fluid temperature should drop below
+3°C by draining the system. This prevents the heating system
from freezing.
If the valve opens and drains the system, no action is required
to reset the valve, the system can be refilled again as soon as
normal circulation in the heating system is resumed.
Insulation is available as an accessory for maximum energy saving.
Refer to Accessories & Spare parts.
