Five Generations of Cool Touch Technology

Plastic Shell+Brass Waterway

Plastic shell wraps all copper water channels, using air and plastic to insulate

Solid Brass Body

The thermostatic valve core is placed on the left to shorten the distance of the hot water channel, and the cold water is mixed at the hot water inlet end

Zinc Shell+PPA WATERWAY

The PPA plastic water channel is used for water, and the air between the water channel and the metal shell is insulated

BRASS SHELL+PPA WATERWAY

The thermostatic valve core is placed on the left to shorten the distance of the hot water channel, and the cold water wraps around the PPA waterway, so that heat will not be transferred to the surface

SOLID BRASS+PPA SLEEVE

The cold water is between the copper shell and the water channel to isolate heat conduction, and the surface of the shell and the cold water have the same temperature.
