商品紹介

The induced-draft counterflow tower uses a top axial fan to draw ambient air upward against warm condenser water distributed above the fill. Evaporation removes heat before cooled water collects in the lower basin and returns to the refrigeration plant. A square FRP casing, removable louvers and modular fill pack provide a compact alternative to crossflow arrangements where footprint matters.

主要な特徴

Counterflow air and water paths distribute heat transfer across the full fill depth.

The fan at the discharge draws air uniformly through lower inlet louvers and reduces recirculation at the intake.

FRP casing panels and stainless support members resist continuous wet service and treatment chemistry.

Access doors, removable fill cassettes and an open basin support inspection of water-contact components.

お客様の製品に関する懸念事項

A cooling tower must reject the design load while controlling footprint, water distribution and maintenance access.

Limited roof area restricts the size of heat-rejection equipment.A vertical counterflow path concentrates fill depth and fan discharge within a compact square plan.

Uneven spray distribution leaves dry fill zones and reduces capacity.A full-coverage header and serviceable nozzles wet the modular fill pack uniformly.

Drift can carry treatment chemicals beyond the tower.Dedicated drift eliminators change exhaust-air direction and capture entrained droplets.

Basin sediment blocks strainers and accelerates corrosion.Accessible sloped basin surfaces, drain points and removable strainers simplify routine cleaning.
