DBHZ₂ / CDBHZ₂ Square Cross-Flow FRP Tower
Air across the fill, water down through it — the low tower you can service from the side.
In a cross-flow tower the air runs horizontally through the fill while the water falls vertically, so the fill and distribution system sit within reach from the access door. Overall height is lower than a counter-flow tower of the same duty, gravity distribution keeps pump head low, and the FRP casing gives a long service life. Low-noise DBHZ₂ and ultra-low-noise CDBHZ₂ versions are both available, with multi-cell arrangement for larger capacities.
Specification
| Tower type | Square cross-flow, FRP casing, low overall height |
|---|---|
| Noise class | DBHZ₂ low-noise · CDBHZ₂ ultra-low-noise |
| Water distribution | Gravity distribution — low required pump head |
| Fill access | Side access for fill and distribution maintenance |
| Casing | FRP — corrosion resistant, long service life |
| Arrangement | Multi-cell modular for large capacity |
| Wall clearance | Single tower 2 m · double 2.5 m · triple 3.5 m · four or more 5 m |
| Air clearance | Outlet to obstruction at least 5 m; wall height below tower height |
| Pipe connection | Flanges to S311, P = 9.8 × 10⁴ Pa; pipe weight carried by separate racks |
Design notes
- Service from the sideFill and spray system are reachable through the side panels, so maintenance does not need a platform on the roof.
- Low silhouetteThe cross-flow layout cuts overall height, which suits roofs and plant rooms with a headroom limit.
- Gravity distributionWater distributes under gravity, so the circulating pump does not have to pay for extra head.
- Clear installation rulesPublished wall-clearance and outlet-clearance figures let the layout be right the first time, before hot-air recirculation shows up as lost capacity.
Options
- Ultra-low-noise build with outlet hood
- Stainless basin and fasteners
- Basin heater and anti-icing control
- VFD drive with temperature-based control
Applications
- Hotels, hospitals and commercial buildings
- Rooftop and low-headroom installations
- Light industrial process water
- Retrofit where plot height is constrained
