NOVAFLO case study

NovaFlo is the best solution on the market to avoid risks of condensation that could lead to the formation of mold in the restricted space between the cold room and the building’s drywall.

Our product development team worked with certain Norbec customers to develop NovaFlo, a forced ventilation system around the cold room.

Before being tested in real situations, this solution was subjected to several rounds of AEF computer simulations in order to ensure the correct dimensioning of the components.



Condensation problems under a floor

The cold, which over time succeeded in getting through the insulated floor of a cold room caused the formation of ice between the concrete slab and the insulated floor. This ice formation caused deformation at the floor level.



A new shim system is in place

The shims allow the floor to be raised and allow convection air to circulate around the chamber, limiting the accumulation of condensation.

The shim system is now part of the Norbec standard offering.



Mold problems persist

Although shims are effective in most situations, mold problems on drywall are still possible.

Customers and installers tell us about mold problems on drywall when dismantling cold rooms.



Launch of NovaFlo

Norbec assesses where the risks are higher by using airflow and heat transfer analysis methods. A turnkey solution including a properly sized ventilator system is developed.

Provide constant ventilation

Norbec must find a solution in case of fan breakdown



Added fan stop detection option

In order to ensure the correct operation of its system, Norbec offers the option of integrating the NovaFlo with its I3 module, which will emit an alarm signal when the fans are switched off.

Technical details 1

1   Optional access hatches are placed on the edge around the ceiling of the cold rom to allow a visual inspection of the space.

2   The junction between the sealed bulkheads in order to provide sufficient air pressure.

3   Powerful fans are positioned in strategic places on top of the room in order to allow optimal air circulation.
