Close-Type Cooling Towers

HOGAT LLC delivers, installs and maintains the Closed-Type Cooling Towers.

Fabrication of Cooling Towers is certified according to ISO SO9001-2000 Standard.

Closed-Type Cooling Towers are manufactured according to the American standard CTI (Cooling Technology Institute) STD-201. Manufactured Cooling Towers are easily transported by road. Before loading on a truck, the Cooling Towers are divided into 2 sections. This makes it convenient to deliver Cooling Towers to their assembly site.  


The main and important advantages of Closed-Type Cooling Towers are:

  • Compact and lightweight design;
  • The Cooling Tower is ready for operation, assembled at the factory;
  • Available modular installation of Cooling Towers;
  • The Cooling Tower design enable to organize closed cycle of cooling water;
  • Low water treatment costs.

The main application scopes of Closed-Type Cooling Towers are:

  • Small enterprises where heat recovery is required;
  • Cooling of Condensers in Absorption and Compressor Refrigeration Machines;
  • Cooling of air compressors;
  • Engine cooling;
  • Cooling of electric furnaces, etc.
Closed-Type Cooling Towers can be conditionally divided into series:

  • FNB Series. Cooling Towers with Air Counterflow and Closed Cooling System;
  • FBF Series. Cooling towers with combined Airflow and Closed Cooling System with one or two Air Intakes;
  • FKY Series. Backed Cooling Towers with AIr Counterflow and Closed Cooling System.
