Pumping group with mixing valve and actuator ESBE GRC221 CRC217+VRG432-25-WILO 61044100

ESBE Pump Group – an effective solution for your heating system

The ESBE GRC221 CRC217+VRG432-25-WILO pump group with mixing valve is a comprehensive solution for heating circuits, providing precise temperature control and optimal energy utilization. Designed for reliability and ease of installation, it will work well in both domestic and more demanding commercial systems. This is a ready-to-install kit that minimizes installation time and ensures reliable operation.

Design and functionality

The pump group combines several key elements that together create an efficient and reliable system:

• Mixing valve: A three-way progressive rotary valve provides precise mixing of heating media, allowing for maintaining a constant output temperature. Its design minimizes the risk of oversizing, which translates into energy savings.
• Actuator: Equipped with an actuator controlled by a PWM signal, allowing for smooth and precise flow regulation.
• Wilo circulation pump: The built-in Wilo circulation pump ensures efficient circulation of the heating medium in the installation. The pump mounting length is 130 mm.
• Check valve: Prevents backflow of the heating medium, protecting installation components from damage.
• Pump ball valve: Facilitates servicing and pump replacement without the need to disassemble the entire pump group.
• Thermometer: The built-in thermometer with a reading range of 0...120 °C allows for continuous monitoring of the heating medium temperature.
• Thermal insulation: High-quality thermal insulation minimizes heat loss and increases the energy efficiency of the system.

Application and benefits

The ESBE GRC221 CRC217+VRG432-25-WILO pump group is an ideal solution for:

• Underfloor heating systems: Provides precise control of the heating medium temperature, which is crucial for the comfort of underfloor heating.
• Heating systems with weather compensation: Works with weather compensators and controllers taking into account internal/external temperature, optimizing energy consumption.
• Installations with glycol: The design of the pump group allows operation with glycol, which expands its range of applications.
• New installations and modernization of existing heating systems.

By using this pump group you gain:

• Precise temperature control: Maintaining a constant temperature in the rooms ensures thermal comfort and energy savings.
• High energy efficiency: Minimizing heat loss thanks to thermal insulation and optimizing pump operation translates into lower heating bills.
• Reliability and durability: The use of high-quality materials (brass, steel) guarantees a long service life of the device. The maximum working pressure is 10 bar.
• Easy installation and servicing: The compact design and ball valve facilitate installation and servicing of the pump group. Connections made in a standard external tapered gas thread (BSPP) and internal BSPP-G (ISO 228-1).
• Expandability: Possibility of expansion with a manifold allows you to create a more extensive heating system tailored to individual needs.

This pump group is an investment in the comfort, savings and reliability of your heating system!
