EWK-DR 930 Cooling Tower developed for temporary installations with “SMART” control panel for continuous performance monitoring

Project Overview

Client and Scope: Our client, a leading provider of rental equipment for fluid temperature control, required a highly efficient cooling solution for their international sites. Vistech Cooling Systems was tasked with delivering two containerised GRP cooling towers (model EWK-DR 930) which would allow for easy transportation between locations.

Technical Solution

Cooling Tower Model: EWK-DR 930 This cooling tower was specifically selected for its advanced features:

  1. External Frame 20’ Container Adapted: The external frame has been adapted to the size of a 20’ container consisting of a self-supporting, steel structure coated with polyurethane to protect against harsh environmental conditions.
  2. Corrosion-resistant GRP casing of the tower: This provides total structural protection in aggressive environments, significantly cutting lifetime operating costs compared to traditional steel models.
  3. Heat Transfer Capacity: 1,800.28 kW
  4. Energy-efficient fan: With a consumption of 28.5 kW, the centrifugal fan provides excellent airflow at low noise levels.
  5. Innovative Solutions: SANIPACKING® anti-legionella technology for preventing bacterial growth.
  6. Smart Control Panel: With an autonomous PLC system that integrates predictive maintenance algorithms to optimise energy use, monitor performance, and recommend maintenance actions.
The tower’s external frame has been adapted to fit a 20′ container, allowing for easy transport and installation in constrained spaces

Challenges and Solutions

Challenges:

  1. Environmental Corrosion: Since the cooling tower needs to be easily relocated, it must endure a wide range of environmental conditions. The team prioritised long-term material durability, ruling out steel options due to their susceptibility to corrosion.
  2. Restricted Space: The tower may need to be installed in a tightly confined area, depending on its location, requiring a design that accommodates limited space

Solutions:

  1. GRP Construction: The cooling tower was constructed from fibreglass-reinforced polyester, which is both durable and corrosion-resistant, particularly in coastal or industrial environments. The 20’ external frame was coated with polyurethane to protect against harsh environmental conditions.
  2. Customised Design: The tower’s external frame was adapted to fit a 20′ container, allowing for easy transport and installation in constrained spaces. Prefabrication enabled a more rapid site install process.
EWK-DR series towers are designed for easy transport, fully assembled on protective structures

Outcomes and Client Benefits

Containerised Cooling: The EWK-DR series is designed for easy transport, fully assembled on protective structures, making them a great fit for temporary installations.

Plug and Play: With a robust chassis and a “SMART” control panel for continuous performance monitoring, they’re ready to be connected and start working right away.

Energy Savings: The energy-efficient fan and smart control panel contribute to reduced operational energy consumption.

Minimal Maintenance: Thanks to the SANIPACKING® fill and drift eliminators, which include anti-legionella treatments, the tower requires less frequent maintenance.
