Newsome Ltd designed, manufactured, installed, and commissioned an integrated HVAC system at the site of a manufacturer of breakfast cereals and bars in Lincoln.
- The oven area consisted of two ovens and a large open area which was serviced by one air handling unit which was woefully undersized for the excess heat produced from the ovens.
- The room experienced consistent temperatures in the region of 40-50°C with product wastage in the region of 30% on certain lines.
- The plan was to divide the area into two areas with a partition wall, creating an oven area and a packing area.
- Our scope was to design and implement a ventilation system to maintain the oven area temperature to a maximum of 8°C at 1.5m above the external ambient temperature and maintain the oven hall at a balanced pressure between adjacent areas.
- The existing air handling unit was rerouted to service the packing area.
- A new HVAC solution was installed to service the oven area.
- The new system comprised of 12 roof input units and 9 roof exhaust units.
- Input units comprised EC Fans, G4 & F7 filtration.
- Exhaust units comprised EC fans and insect screening.
- Temperature and pressure all controlled by a Trend based system.
- Consistent temperatures within the oven hall at the setpoint of 25°C
- Consistent room pressures
- Product wastage reduced from 30 to 18%
