Laddomat 21-60 thermal return increase for boilers with pump

Laddomat 21-60 thermal return flow booster – Efficient control for your buffer storage tank

Product description

The Laddomat 21-60 offers a compact and reliable solution for optimal charging of your buffer tank. Combined with precise hot water control, the Laddomat 21-60 quickly reaches the desired operating temperature of the boiler while ensuring a high, consistent water temperature.

It is designed to optimize the operation of the heating system by feeding the buffer tank at a low flow rate, thus ensuring ideal stratification. This significantly improves the tank's performance and extends the service life of the connected boilers.

How it works and advantages

During the heating process, the Laddomat 21-60 actively promotes the achievement of the optimal operating temperature by selectively increasing the temperature in the boiler's return line. This effectively prevents boiler corrosion and extends the boiler's service life.

During the final firing phase, the integrated thermal valve shuts off the bypass outlet, ensuring the buffer tank is fully charged. Furthermore, the residual heat in the boiler (ember bed) is optimally utilized through self-circulation – a function that works reliably even during a power outage.

Assembly and maintenance

The robust construction with high-quality sealing surfaces allows for quick and easy installation of the Laddomat 21-60. The design is engineered for maximum durability and trouble-free operation, supporting the long-term operation of the heating system.

Ball valves with Teflon gland seals and a robust metal lever ensure easy maintenance. These allow maintenance work without draining the system and easily handle high flow rates at the end of the heating cycle and during self-circulation.

Technical data

The Laddomat 21-60 is available with a thermocouple in various versions (53°, 57°, 63°, 66°, 72°, 78°, 83°, or 87°C). Models such as the Laddomat LM 6 (non-EU) and the Laddomat LM 6A (ErP) are available for the pump.

It boasts connection options for Cu28 and R32, as well as optionally available R40 and R50 adapter sets. The recommended maximum boiler output is up to 80 kW.
