PRECAST CONCRETE
The Sector
Precast concrete manufacturing depends on curing: loading freshly mixed concrete on pallets at an elevated temperature for a set period so it gains strength from its hydration reaction, before unloading and packaging. That heat is usually supplied by hot air or water, circulated around the curing chambers, either as a batch process or continuous operation.
Many precast sites, particularly those in rural locations, have no connection to the mains gas supply and heat is generated using fuel oil or LPG boilers, with higher costs and carbon emissions.
Decarbonisation in Precast Concrete
Because curing temperatures typically sit in the 35–40°C range, this is well within the operating envelope of high temperature air source heat pumps. That makes precast concrete one of the more straightforward sectors to decarbonise: the heat pump technology is well suited to the process of continuous or batch curing on a schedule.
For sites already running on fuel oil or LPG rather than mains gas, the economics of switching to zero carbon electricity are often more favourable.
How We Bring the Change
First, we assess your curing process, by understanding your chamber construction, curing cycles, heating system, loading patterns, current fuel usage and cost. Where a phased approach is required to demonstrate the switchover, we'll convert one production line or factory area first, prove the numbers, and scale from there, exactly how our first precast concrete project was delivered.
Thermal buffer tanks are built into the design where the curing schedule can support it, so you're not just switching fuel, you're using the heat in an optimised way.
