Symmons introduced the Max Line ASSE 1070 thermostatic tempering device, which it says is a cost-efficient solution for controlling and limiting water temperature to fittings for fixtures such as sinks, lavatories or bathtubs. Designed for applications where the temperature of generated hot water must be tempered and controlled before distribution, water must completely pass over the thermal motor before discharge, ensuring that delivery temperature will be maintained even with water flow far below the rated capacity.
