MCH heaters for instant water heating
Tankless heating is a power-density and safety problem: you need a lot of heat in a short flow path, with the live circuit completely isolated from the water.
Isolation by construction
In an MCH element the tungsten circuit is buried inside dense alumina. The outer surface is ceramic, not a live conductor, which makes water-electricity separation a structural property rather than an extra coating that can wear off.
- 4,500 V / 1 s withstand, leakage < 0.5 mA
- High power density for short flow channels
- Fast response to flow and temperature changes
- Tube, ring and flat plate formats
- Lead-free, RoHS / REACH compliant
Module-level supply
Most customers here buy an assembly rather than a bare chip: heater, flow channel or housing, thermal fuse, thermostat, seals and connectors, tested as one unit with 100% end-of-line dielectric and power checks.
- Heater + housing + protection in one part number
- Custom flow path and inlet / outlet geometry
- Dry-burn protection and thermal cut-out
- Function test at rated voltage before shipment
Specifications
Questions buyers ask
We integrate a thermal fuse / thermostat in the assembly and validate the trip point under no-flow conditions during design verification.
We supply the co-fired element and lead assembly; housing and flow-channel integration is done on your side. Send the flow rate, inlet temperature and target outlet temperature and we will propose the element geometry and power.
Discuss flow heating
Flow rate, inlet / outlet temperature, available space and voltage are enough for a first proposal.
