Our cellular inlet louvres improve the air flow into the cooling tower. They not only hold back unwanted elements (e.g. leaves) but also prevent water splash-out which can cause icing and loss of expensive water and treatment chemicals. Moreover, an inlet louvre restricts the amount of sunlight entering the cooling tower thereby impeding algae growth. Also the tower‘s clean appearance is maintained.

Cellular louvre type

  1. Prevents water splash-out
  2. Prevents ingress of leaves into the cooling tower
  3. Restricts the amount of sunlight into the cooling tower impeding algae growth

Low pressure drop

Flexibility in material and dimensions allows adaptation to plant requirements according to customer request
Long service life due to chemical and UV resistance of PP and PVC Opposed Blade Louver Dampers are used where the system requires air flow control or balance and can be used for on-off service.

Custom Louver Dampers

Parallel Blade Louver Dampers are available for open-close service, fixed flow balance control, and for use as a variable control damper at the inlet box of a fan to pre-spin the air entering the fan wheel.
Multi-louver parallel blade fan inlet dampers, with air foil blades, provide excellent fan control. High strength adjustable blade linkage with self-aligning rod ends is available, in addition to refractory lining for operation in high-temperature conditions.
Multi-louver parallel blade isolation dampers for open-close service or fixed flow balance control are manufactured with stainless steel spring seals that reduce leakage to less than 1%. Self-aligning blade shaft packing glands are available to maintain exact concentricity of the packing to the blade shaft at all times, providing maintenance-free service.
Fan outlet multi-louver opposed blade dampers are designed to provide balance flow control. Internal stainless steel spring seals furnish tight shut-off, allowing isolation of the fan for maintenance. Heavy duty adjustable blade linkage with high strength spherical rod ends provide precise blade movement, while self-lubricating high temperature spherical carbon sleeve bearings running on stainless steel shaft allow for maintenance free service.
