WZS pump groups are designed for fast, convenient and optimal implementation of the hot water circulation system at the hot water storage tank. Clever compact design of groups minimizes the risk of incorrect execution of DHW installation. WZS groups have been designed for installation both with and without hot water storage tanks equipped with a dedicated circulation connector. All WZS groups are factory checked for leaks. They are equipped with an energy-saving WILO circulation pump (max 5 W) and a thermostatic mixing valve ATM (35÷60°C) with a burn protection function.

is in:

• thermostatic valve ATM 563, Kvs 2,5 m3/h
• WILO circulation pump (max 5 W)
• thermometer 0÷120°C with built-in shut-off valve
• 4 built-in check valves
• shut-off valves
• bleed and vent valve
• MSW safety valve
• EPP insulation

Technical parameters:

• Kvs: 2.5 m³/h
• connection: 5x Rp3/4''
• maximum pressure: 10 bar
• temperature control range: 35÷60°C
• maximum temperature of the medium: 90°C

USE:

• Used in domestic water installation.
• Mounted near the hot water tank
• Helps to quickly make an optimal DHW circulation system.
• The ATM thermostatic valve prevents burns and allows you to safely raise the temperature in the tank (e.g. to heat up or increase the amount of hot water).
