REHAU PP-R pipe delivers efficient chilled water and low-temperature hot water distribution

For this project Mibec were contacted to support implementing a district energy system for Peterhouse Technology Park, a new science and tech hub in Cambridgeshire. 

The customer required pre-insulated pipes to distribute chilled water (CHW) and low-temperature hot water (LTHW). The primary objective was to ensure efficient thermal energy transfer while minimising heat losses and maintaining system reliability over long distances. 

The Mibec team found it straightforward to identify REHAU's PP-R pipe as a suitable large-diameter solution with effective thermal insulation over long pipe runs. 

PP-R pre-insulated pipes are a reliable and sustainable solution for modern systems, offering superior performance and longevity. These pipes are highly corrosion resistant, scaling and chemical degradation, ensuring long service life.

REHAU PP-R pipes are durable, versatile and have excellent thermal stability, making them ideal for projects like this. 

Installation

 The pipe was required for a large CHW flow and return, sized at 250mm carrier pipe with an insulated outer diameter of 400mm and a LTHW, sized at 160mm carrier pipe with an insulated outer diameter of 250mm. 

To ensure the pipework was correctly installed, REHAU provided installation training for Gas and Water Ltd. This training gave the on-site team the confidence to install the pipe system successfully and certified then as REHAU Authorised Installers.
