## Summary description

Oventrop Unibox E RTL is a white pipe-mounted device for limiting the temperature of the fluid in heating or cooling pipes. Model 1022731 monitors and restricts inlet fluid temperature to protect system components and ensure safe operation. It is designed for integration into hydronic installations where controlling pipe fluid temperature is required.

## Long description

The Oventrop Unibox E RTL white is a pipe-mounted inlet fluid temperature limiter designed for hydronic heating and cooling systems. This compact device monitors the temperature of the fluid entering a section of piping and activates a control action when the preset threshold is exceeded, protecting downstream components and helping maintain safe operating conditions. The white enclosure and inline connection make it suitable for visible installations where a discreet, professional appearance is required.
Advantages
The device provides reliable, automatic temperature limitation using a mechanical sensing element, reducing the need for manual intervention. Its compact form factor permits straightforward installation on supply pipes without significant space requirements. The unit is compatible with common hydronic systems and is built to withstand conditions typical for heating and cooling circuits. By limiting inlet fluid temperature, it helps prevent damage to sensitive components and contributes to system safety.
Suitable for
Residential and commercial hydronic heating systems
Underfloor heating manifolds and distribution cabinets
Cooling circuits where inlet temperature control is required
Protection of heat exchangers, pumps and valves from excessive inlet temperatures
Key specifications
Mounting: pipe-mounted inline installation
Function: limits inlet fluid temperature by activating control action at set threshold
Material and finish: white enclosure suitable for visible installations
Compatibility: designed for use in hydronic heating and cooling circuits
Operation: mechanical temperature sensing for automatic response
Size: compact design for installations with limited space
How to use
Install the Unibox E RTL on the supply pipe in the position recommended by the system designer, ensuring correct flow direction and adequate access for adjustment and inspection. Connect the device into the piping using appropriate fittings and sealing methods for the system pressure class. After installation, verify that the temperature limit setting matches the requirements of the heating or cooling circuit and test operation by gradually increasing inlet fluid temperature to confirm activation at the intended threshold. Regularly inspect the unit for secure mounting and signs of wear.
Usage recommendations
Use the Unibox E RTL as part of a coordinated control strategy: pair it with properly sized pumps, valves and temperature controls to ensure stable system performance. Follow local codes and manufacturer guidance for mounting height, pipe insulation and access for maintenance.
