- Circulating 25% Glycol solution through a chiller feeding 3 off AHUs
- AHUs used to cool production areas through ducting and wall plenums
- Press-fit stainless-steel pipework from 108mm down to 45mm
Controls system
- Centralised control panel with running and error notifications for all pumps
- Level display and pump control system for each tank including dry-run protection
- Connections for BMS if required
All systems
- All 3-piece stainless steel valves
- Negates the need for unions therefore reducing costs
- Prolongs service life reducing costs and system downtime
- All variable-speed pumps with Bluetooth connectivity
- Maximum energy efficiency reducing costs and carbon footprint
- Negates the need for flow control valves reducing costs
- Increases efficiency of systems
- Maximum system control
- All high-flow filters
- Maximum service life
- Increased system efficiency
ACAS Engineering worked alongside several other contractors to ensure that the project was delivered exactly to client specification and functioned at the highest possible levels of efficiency and reliability, ensuring the client could proceed without concern for years to come.
