The Client –
Plastics Blow Moulder
The Challenge –
Energy Efficient Upgrade
The Solution –
Complete Cooling System Design
For a client with a legacy cooling system, a full system upgrade gave them the opportunity to benefit from the latest in energy efficient cooling technology.
Our client, an end user, specialises in plastics blow moulding and initially asked Aqua to carry out an energy evaluation on their existing factory set up. Our engineering team then designed an upgraded system with estimated annual costs savings from reducing overall energy consumption. When it comes to energy calculations, we are completely transparent and pride ourselves on living up to our predicted savings.
The suggested upgrade centred around utilising highly efficient free cooling technology, alongside inverter driven pumps. New chiller units were added to two production lines – on the injection moulding side and the blow moulding. Based on our client’s annual production schedule, energy cost savings were forecast at over £70,000. The free cooling also reduces the run hours on the chiller units, increasing their overall life expectancy.
An additional advantage for our client from moving to the new system was the warranty, giving them peace of mind for the years ahead.
The full solution included:
- Energy efficient design review with energy calculations
- Free cooling chillers
- Inverter driven pumps
- Mechanical installation & final commissioning
- Aftersales support
“Our client had become exasperated with their old system, experiencing long lead-times from the manufacturer when they needed to source replacement parts and then discovering some spares had become obsolete. That said, I think the prospect of a full system upgrade initially made them nervous because of the anticipated costs involved. However, our energy review quickly established that upgrading their equipment would bring them so many advantages. As well as a very quick payback – less than 2 years – they will make significant energy and cost savings every year” explains Aqua Sales Manager, Shaun Lancaster.
