Why this model

Global voltage, one compact body

Variable-frequency constant temperature across 110–220 V — one model for markets that would otherwise need two.

110–220 V from one model

110–220 V from one model

Wide-voltage adaptation lets the same unit ship to low-voltage and high-voltage markets. One SKU, one spare-parts list, fewer variants in your warehouse.

Constant temperature, variable frequency

Constant temperature, variable frequency

Variable-frequency control keeps the outlet steady while the supply or the flow moves, so the shower does not swing hot and cold when a tap opens elsewhere.

105 × 68 × 191 mm

MOQ 1 pc

The sample price difference comes back
