WJT Series Forced Draft FRP Cooling Tower - Low Noise, Built for Indoor Industrial Use
WJT Series Cooling Towers Structure
Natural draught jet type cooling tower works on water jet principal. In this system the required amount of water to be cooled is sprayed from top of the cooling tower through special jet nozzles. When water comes out of nozzles, it forces the air column in the downward direction of the cooling tower resulting in the low pressure zone inside of the cooling tower. Due to this process atmospheric air comes inside the cooling tower for the required heat transfer of the hot water to be cooled.
- Designed for operating economy & negligible maintenance.
- The special characteristics of Fiber-reinforced plastic provide excellent resistance to corrosion
- These cooling towers works on water jet principal.
- These Cooling towers offer low maintenance due to fan less-fill less construction.
Wetpoint WJT Series is a forced draft FRP cooling tower manufactured by Wet Point Aqua Equipments Pvt. Ltd. in Gwalior, Madhya Pradesh, India. Available from 5 TR to 500 TR, it is designed for low noise operation and indoor or space-constrained industrial installations – where conventional induced draft towers cannot be used due to height restrictions, enclosures, or noise sensitivity.
Trusted by plant engineers, HVAC consultants, and procurement teams across 50+ cities in India since 1996, the WJT Series is the go-to forced draft cooling tower for machine tool shops, DG set rooms, pharmaceutical utilities, and commercial HVAC plant rooms.
What is a Forced Draft Cooling Tower?
In simple terms: A forced draft cooling tower uses a fan at the base or side of the unit to push air into the fill, cooling hot water flowing downward. The fan works before the air contacts the hot humid fill – making it quieter and more accessible for maintenance.
In a forced draft cooling tower, the fan is positioned at the bottom or side of the tower and pushes air through the fill media. Hot process water enters from the top, flows down through the fill, and is cooled by the rising airstream. The cooled water collects in the basin below and is returned to the process.
Because the fan operates in the cool incoming airstream – rather than in the hot, humid discharge air – it runs cooler and generates less noise at the outlet. This is what makes the WJT Series ideal for indoor, basement, and enclosed plant room installations where noise and height are constraints.
How the WJT Series Forced Draft Cooling Tower Works
Here is the cooling cycle step by step:
Step 1 – Hot water intake: Hot process water (from DG set, chiller, HVAC, or process equipment) enters the top distribution header of the WJT tower.
Step 2 – Air push: The centrifugal fan at the base pushes ambient air upward through the PVC honeycomb fill media.
Step 3 – Evaporative cooling: Hot water flows downward over the fills while cool air flows upward – the temperature difference drives evaporative heat transfer, cooling the water by 5–8°C depending on wet bulb conditions.
Step 4 – Drift elimination: FRP drift eliminators at the top capture water droplets carried by the airstream, minimising water loss.
Step 5 – Cooled water return: Cooled water collects in the FRP basin and is pumped back to the process equipment, completing the cycle.
Key Features of the WJT Series Forced Draft FRP Cooling Tower
Low Noise Design - Suitable for Noise-Sensitive Environments
The WJT Series uses a centrifugal fan with vibration isolators and a rubber anti-vibration mounting base, which significantly reduces structural vibration and airborne noise compared to axial fan induced draft towers. This makes it the preferred low noise cooling tower for hospitals, commercial buildings, residential complexes, and factory floors where noise complaints are a concern.
Compact, Low-Profile Design for Indoor Installation
Unlike induced draft towers that discharge air vertically and require unobstructed overhead clearance, the WJT Series has a low overall height and side or top air discharge options – making it suitable for indoor installation in factory sheds, basement plant rooms, and enclosed equipment bays. Ducted airflow arrangements are available on request for installations requiring air intake and discharge through walls or roofs.
FRP Construction Throughout
The casing, basin, fan cylinder, and drift eliminators are all manufactured from UV-stabilised, corrosion-resistant FRP. There is no painted metal in the air and water stream – no rust, no paint flaking, no structural degradation from cooling water treatment chemicals. FRP construction is standard on every WJT unit – not an optional upgrade.
IE2 and IE3 High-Efficiency Motor Options
All WJT Series units are fitted with IE2 or IE3 rated induction motors (415V, 3-phase, 50Hz), reducing energy consumption and qualifying for BEE energy efficiency incentives. Motor enclosure rating is IP55 as standard – fully protected against dust and water jets – suitable for outdoor installation where required.
PVC Honeycomb Fills for Maximum Thermal Efficiency
High-surface-area PVC honeycomb fill media provides maximum contact between air and water with minimal air pressure drop. Optional splash fills or trickle fills in PP material are available for high TDS or high suspended solid water quality – common in Indian industrial water conditions.
Spares and Components of WJT Series Cooling Towers:
Water Distribution Pipes
Non-corrosive PVC/FRP piping is used for distributing water to the jet nozzles efficiently. These pipes are designed for low pressure drop and durability.
Inlet Louvers
Plastic or FRP inlet mesh prevents dust, leaves, and other contaminants from entering the cooling tower, ensuring clean operation and reducing clogging.
Fasteners & Clamps
Galvanized or stainless-steel fasteners, clamps, and supports are used for securing internal components and ensuring structural integrity.
Collection Basin / Sump
FRP basin collects cooled water and ensures leak-proof storage before recirculation.
Make-up Valve / Float Valve
Used to maintain water level automatically in the cooling tower basin by regulating make-up water supply.
Support Structure Components
Galvanized steel supports, brackets, and frames ensure stability and proper alignment of all tower components.

The WJT Series - When Noise and Space Are Non-Negotiable
Most cooling towers are designed for open outdoor installation. The WJT Series is engineered for the other 30% of applications – where the site is indoors, the headroom is limited, the neighbours are close, or the noise regulations are strict.
If you’re cooling a DG set inside a hospital basement, a chiller plant in a commercial building, a CNC machine on a factory floor, or a pharma utility in a GMP facility – the WJT Series forced draft FRP cooling tower was built for exactly that application.
Manufactured in Gwalior by a cooling tower manufacturer in India with 30+ years of experience, every WJT unit is custom-engineered to your site conditions and backed by genuine spare parts and after-sales support.
Frequently Asked Questions About WJT Series Forced Draft Cooling Towers
The WJT Series is a forced draft FRP cooling tower manufactured by Wet Point Aqua Equipments Pvt. Ltd. in Gwalior, India. It uses a centrifugal fan at the base to push air through PVC honeycomb fills, cooling hot industrial process water. Available from 5 TR to 500 TR, it is designed for low noise, indoor, and space-constrained installations in pharmaceutical, HVAC, DG set, and machine tool applications.
The WJT Series uses a centrifugal fan at the base that pushes air into the tower (forced draft). The WDF Series uses an axial fan at the top that draws air up through the fill (induced draft). WJT is better for indoor and low-noise applications; WDF is better for outdoor, high-capacity installations where energy efficiency is the priority. See our detailed induced draft vs forced draft guide for a full comparison.
WJT Series cooling towers operate at 55 dBA to 70 dBA depending on model capacity. The 5 TR WJT-I operates at ≤55 dBA – quieter than normal conversation – making it suitable for hospital corridors, data centre rooms, and residential proximity installations. Larger models (300–500 TR) generate up to 70 dBA, which is comparable to a standard office environment. Sound attenuation packages are available for applications with stricter noise requirements.
Yes – the WJT Series is specifically designed for indoor installation. Its compact, low-profile design and side/top air discharge configuration make it suitable for factory sheds, basement plant rooms, enclosed equipment bays, and rooftop plant rooms with limited headroom.
