ESBE GxA & GxC

The ESBE series GRA200 are circulation units intended for heating circuits where an outstanding flow and temperature control are required. Equipped with two shut-off valves with thermometers, check valve, high class insulation shell and a high efficiency circulation pump. The units are delivered with a 3-way rotary progressive mixing valve which ensures best regulation performances independent from flow rate and low oversizing risk.

The Series GRA200 comes with actuator series ARA661 with 3-point control signal, 230V AC, or actuator series ARA639 proportional control signal,24V AC/DC. The circulation units are available in DN25 and DN32 with either a Wilo or Grundfos pump. 
The Series GRA300 with very compact dimensions are equipped with actuator series ARA661. Series GRA300 is available in DN20 with a Wilo pump with PWM control signal.

• Outstanding flow control thanks to the progressive characteristic of the valve
• 2 different types of actuator: 3-point or proportional control signal (depending on version)
• QuickFit interface between actuator and valve - no tools needed
• 2 different high efficiency circulation pumps
• Available in 2 sizes: DN25, DN32
• High class insulation shell
• Pretested and ready to use
• Compact design

The ESBE series GDA200 are direct supply circulation units designed for applications, where an energy transport in the most efficient way is required. Equipped with two shut-off valves with thermometers, check valve, high class insulation shell and high efficiency circulation pump. 
The direct groups series GDA200 are available in DN25 and DN32 with either a Wilo or Grundfos pump. Series GDA300, with very compact dimensions, is available in DN20 and comes with a Wilo pump with PWM control signal.
