Core Structure & Components
STRUCTURE & CASING
The tower enclosure is made in special alloy (Mg-Al-Zn) coated steel panels. These panels exhibit superior corrosion resistance and self-heal when scratched during the service period. The panels are bolted and sealed for water tightness. The casing is complete with maintenance access doors for internal inspection convenience.
DRY COOLING COILS
The dedicated dry cooling coils are used exclusively for the purpose of dry cooling, fitted with particularly shaped aluminum fins around the coils tubes to maximize surface area of heat transfer. The standard coils tubes is made in stainless steel 304 (0.6mm thickness) or red copper (0.8mm thickness). Each coil is tested under 30 bar nitrogen gas pressure for 24 hours.
AXIAL FAN SECTION
The axial fan(s) are fitted with resin or al-alloy airfoil blades perfectly balanced and coupled to a weather-proof three-phase electric motor. The fan casing is a galvanized steel cylinder to draw air vertically and avoid recirculation risk.
ELECTRICAL CONTROL
Each dry tower is under control of an electrical control unit. The control box can be made in powder coated carbon steel or stainless steel. PLC systems can be programmed for digital or remote control according to project demands.
SURFACE FINISH
Delivered in alloy coated steel finish without additional painting, providing a durable industrial-grade surface.

Frequently Asked Questions
Q1: What materials are used for the cooling tower casing?
The enclosure uses special Mg-Al-Zn alloy coated steel panels, which offer superior corrosion resistance and self-healing properties compared to standard galvanized steel.
Q2: How are the dry cooling coils tested for quality?
Each coil undergoes a rigorous testing process under continuous nitrogen gas pressure of 30 bar for a full 24 hours to ensure there are no leakage points.
Q3: What are the options for cooling coil tube materials?
Standard options include Stainless Steel 304 with a 0.6mm wall thickness or Red Copper with a 0.8mm wall thickness. Other thicknesses can be provided upon request.
Q4: Can the cooling tower be controlled remotely?
Yes, while standard towers come with a manual electrical control unit, we offer PLC programming for digital or remote control functions to meet specific project demands.
Q5: What information is needed for a proper model selection?
Key data includes the application type, required water flow rate (m³/h), inlet and outlet water temperatures, the highest ambient wet-bulb temperature of the location, and power supply specifications.
Q6: Are the fans designed for noise control?
Yes, the axial fans use airfoil blades and the tip speed of the impeller is specifically limited to keep noise levels within acceptable industrial limits.
