The Laddomat 22

With its construction with a massive cast iron body, it replaces the classic connection of individual hydraulic fittings for the boiler circuit (thermoregulation valve, pump, non-return valve, ball valves, thermometers, fittings and insulation). Laddomat 22 can be used for boilers with output from 15 to 100 kW. The Laddomat 22 is supplied with a 78 °C thermocartridge and a spare 72 °C thermocartridge placed in polystyrene insulation. We use the 72 °C thermal cartridge for boilers over 32 kW or for systems without an accumulation tank, where there is no requirement for a higher operating temperature of the boiler. Connecting with Laddomat 22 is much easier and therefore we can only recommend it.

When connecting the boiler, a thermoregulation valve TV 60 °C (65 °C) or a three-way mixing valve controlled by regulation with a servo drive can also be used to protect against low-temperature corrosion, which will maintain the temperature of the water returning to the boiler min. 65 – 75 °C.

Laddomat 22 has the task of:

Ensure that the boiler reaches operating temperature quickly after ignition
Charge storage tanks to high temperature with low flow rate to achieve optimal stratification in the tank
After heating, transfer the remaining heat from the boiler to the tank
In the event of an interruption in the supply of electricity. Flow and stopping the circulation pump to partially remove excess heat through the non-return valve from the boiler to the tank or system by gravity circulation.
