DHW heat exchanger for gas boilers OKC 125 NTR with a spiral coil, enameled 1103708101

Domestic hot water heat exchanger for gas boilers

This 125-liter enameled domestic hot water heat exchanger with a spiral coil is a solution dedicated to year-round operation with a gas boiler. The design without an electric heating element makes it ideal for use with a central heating boiler, providing efficient water heating throughout the year.

Construction and application

The OKC 125 NTR heat exchanger is characterized by a single coil with a large heat exchange surface area. This design is particularly beneficial when powered by a boiler or condensing boiler – it ensures fast and efficient water heating. The spiral coil increases the heat exchange surface area, which translates to higher efficiency and shorter water heating times.

Durability and corrosion protection

The materials and technologies used ensure the long-term reliability of the device. The steel tank is coated with a high-quality anti-corrosion Crystal Enamel coating, which increases resistance to hard and chlorinated water. Additional corrosion protection is provided by a magnesium anode, which protects the inner surface of the tank. Modern ThermoGen4 insulation minimizes heat loss to the environment, which translates to lower operating costs. Energy efficiency class C provides a reasonable balance between performance and energy consumption.

• Crystal Enamel coating: Increased corrosion resistance, even in aggressive water.
• Magnesium anode: Additional protection against internal tank corrosion.
• ThermoGen4 insulation: Minimal heat loss and lower water heating costs.
• Steel tank: Durable construction guaranteeing long device life.
• Spiral coil: Large heat exchange surface area for fast water heating.
