FRP Cooling Towers

FRP cooling towers built under the POLO brand.

Weldon Engineers manufactures its complete cooling tower range under the POLO brand, from compact 10 TR bottle towers to multi-cell rectangular units of 600 TR and above. Every tower is moulded in fibre reinforced plastic, so it will not rot, rust or corrode the way timber and mild steel towers do.

What to know before you specify

A cooling tower rejects the heat your process cannot keep. Warm return water is distributed over a fill pack, ambient air is drawn through it by an axial fan, and a small fraction of the water evaporates. That evaporation carries the heat away, which is why tower selection is driven by wet bulb temperature rather than dry bulb.

Our engineering team sizes each tower against your actual heat load, flow rate, range and approach, then builds the unit to suit the site. Because we handle design, manufacture, erection, commissioning and after sales service in house, there is one accountable party from enquiry through to annual maintenance.

FRP construction is specified for good reason. The shell is chemically inert, it tolerates the aggressive water chemistry found in chemical plants and distilleries, and the moulded panels arrive light enough to lift into place without heavy cranage. That keeps installation short and structural steelwork modest.

POLO Round FRP Cooling Tower

Compact bottle shape tower for tight plant rooms and terraces

The round bottle tower is the most space efficient unit we build. Its circular plan gives even air distribution around the full circumference, so it delivers rated duty from a footprint that a rectangular tower of the same capacity cannot match.

Features

Seamless moulded FRP shell in a single bottle profile
Induced draught axial fan with a tapered FRP fan stack
PVC honeycomb fill for high surface area per cubic metre
Sprinkler type rotary distribution needing no external pressure
Mesh air inlet screen that keeps debris out of the basin

Specification

Capacity range: 10 TR to 200 TR
Shell material: Fibre reinforced plastic
Fill: PVC honeycomb, 19 mm flute
Fan: Aluminium alloy axial, direct or belt driven
Distribution: Rotary sprinkler head
Design wet bulb: 28 degrees Celsius, adjustable to site

POLO

POLO FRP Square Type Cooling Tower

Modular square tower that banks into multiple cells

The square tower uses cross flow louvres on all four faces and a flat top fan deck. Because the plan is square, cells can be banked side by side to build capacity in stages rather than replacing the tower when the plant grows.

Features

Cross flow louvres on four faces for balanced air entry
Flat fan deck carrying the motor above the drift eliminator
Bolted FRP panels that can be replaced individually
Multi cell banking for staged capacity expansion
Optional FRP ladder and handrail to the fan deck

Specification

Capacity range: 25 TR to 400 TR per cell
Configuration: Single cell or banked multi cell
Air flow: Induced draught, cross flow
Fill: PVC film fill with integral drift eliminator
Basin: Moulded FRP with overflow, drain and make up
Reference install: 100 TR at Kandhari Beverages, Saha

POLO

POLO Rectangular FRP Cooling Tower

Multi-cell counter flow tower for large industrial heat loads

For heat loads beyond the practical limit of a single square cell, the rectangular tower places several counter flow cells on a shared basin. Each cell has its own fan and can be isolated for maintenance while the rest of the tower keeps running.

Features

Shared FRP basin with independently isolatable cells
Counter flow arrangement for the closest achievable approach
Individual fan per cell, so part load running stays efficient
Walkway, ladder and handrail for safe fan deck access
Header piping and valving supplied to match plant layout

Specification

Capacity range: 200 TR to 1000 TR and above
Cells: Two to eight on a common basin
Air flow: Induced draught, counter flow
Fill: PVC film fill, low fouling grade available
Fan drive: Belt drive or gearbox with hollow shaft motor
Reference installs: 600 TR at Devan’s Samba and 400 TR at NIFTEM Kundli

POLO

POLO Field Erected Cooling Tower

Site built towers for capacities beyond factory transport limits

Where the duty is too large to ship as moulded assemblies, we erect the tower on site. Panels, fill, mechanical equipment and distribution arrive as a kit and our erection crew builds against the civil basin your contractor has cast.

Features

Built onto a client cast RCC basin to suit the plot
FRP casing over a hot dip galvanised or pultruded FRP frame
Erection, alignment and commissioning by our own crew
Thermal performance testing witnessed at handover
Layouts developed against your civil and piping drawings

Specification

Capacity range: 500 TR upward, project specific
Structure: Pultruded FRP or hot dip galvanised steel
Casing: FRP panels with UV stabilised gel coat
Basin: Client cast RCC, designed by us
Scope: Supply, erection, commissioning, performance test
Approvals: MES, CPWD, PWD, DRDO, BHEL and AAI
