前田鉄工所 Product Lineup

The "BUL type, BTL type, and BPL type" are non-corrosive FRP main body and stable sand filtration type hot water circulation filtration devices for bathtubs. The "BUL type" is a filtration unit that does not incorporate a heating source such as a heater or heat exchanger, and is configured by connecting it to bathtub water heated by other heat sources (boilers or heaters). In addition, we offer the "BTL type" and "BPL type," which incorporate heat exchangers as heating devices. 【Features】 ■ Non-corrosive FRP main body ■ Sand filtration type ■ Significant fuel cost savings ■ Detects the temperature of bathtub water and controls the temperature via a switching valve (BPL type) *For more details, please refer to the PDF materials or feel free to contact us.
