ミヤワキ List of Products and Services

The "LMG1 type" is a safety addition device specifically designed for the steam instantaneous water heater "QuickHot LM15 series." It is a system product that detects the hot water supply of the LM15, opens the steam solenoid valve (commercially available), and closes the steam solenoid valve when hot water is not being supplied. This reduces the load on the water heater itself and prevents the backflow of hot water that can occur in the event of a water heater failure. 【Features】 ■ Design considering safety - Reduces the load on the water heater - Automatically cuts off the supply of steam when hot water supply is stopped ■ Model that has passed leaching performance tests *For more details, please download the PDF or feel free to contact us.
