FUME HOOD MONITORING AND CONTROLS

SUREFLOW™ room controls are designed to maintain room balance in Variable Air Volume laboratories by ensuring that the exhaust is greater than or less than the supply by a set volume. SUREFLOW controls also directly control heating and cooling in the space to maintain a comfortable temperature.

TSI's controls are able to go the additional step and close the loop on room pressure. TSI's exclusive through-the-wall room pressure sensor measures the actual room pressure differential. The SUREFLOW controls use this information to reset the difference between the exhaust and supply air volumes to account for long-term changes in the building.

Finally, SUREFLOW controls are designed to give you flexibility. These controls will work with almost any control component.
