Series Biawar - K-2

Biawar - K-2

The Biawar K-2 series is a line of high-performance flow-through water heaters designed for reliable hot water supply in commercial and light industrial settings. Built for everyday use, these units deliver instant hot water without the need for large storage tanks. The series includes two main model groups: the OP-9 / 12 / 15.07 and the OP-18 / 21 / 24.07, both running on 400 V three-phase power. Each heater features a clear LCD control panel, making setup and adjustments straightforward for any technician on site.

Key Features for Installers

Installers will appreciate the straightforward design of the K-2 series. The LCD display shows real-time temperature, power status, and fault codes, which speeds up commissioning and troubleshooting. The units are built with corrosion-resistant heating elements and a compact metal housing that fits easily into tight utility rooms or mechanical closets. Standard pipe connections and clearly marked terminals reduce wiring time and minimize the chance of connection errors during installation.

Flexible Power Options

The K-2 series offers two power ranges to match different site demands. The OP-9 / 12 / 15.07 models provide steady hot water for medium-use areas like staff kitchens, cleaning rooms, or small workshops. For higher demand locations such as large commercial kitchens, laundries, or multi-station wash areas, the OP-18 / 21 / 24.07 models deliver faster flow rates and higher temperature recovery. Both ranges run on standard 400 V three-phase supply, making them compatible with most commercial electrical panels.

Reliable Performance and Safety

Consistent hot water delivery is critical for daily operations, and the K-2 series is engineered to meet that need. Advanced flow sensors activate heating only when water is moving, saving energy and reducing wear on components. Built-in safety features include overheat protection, dry-fire prevention, and thermal cutoff switches. These safeguards protect the unit and the building, giving installers confidence that the system will run safely without constant monitoring.

Easy Integration and Maintenance

Commissioning the K-2 heaters is quick and straightforward. The intuitive LCD menu guides technicians through basic settings, while accessible terminal blocks and removable front panels simplify future servicing. Standard plumbing connections allow easy integration into existing hot water loops, and the durable construction ensures long service life with minimal downtime. Biawar backs the K-2 series with clear documentation and responsive technical support, so installers can complete jobs faster and with fewer callbacks.
