Product catalog summary
Intended Use
Fan coolers are designed for cooling liquids, primarily hot water, using external air. They are suitable for industrial plants and manufacturing processes that require cooling of liquids. These units are intended for outdoor installation.
Unit Description
The CHW series includes three sizes, each with multiple fans arranged in one or two rows. The main components are fin heat exchangers, axial-flow fans, and casing frames. The heat exchangers are made of copper pipes with a 16mm diameter and aluminum fins spaced at 2.5mm. Standard connectors are screwed. Heat exchangers come in two versions: three-row for all sizes and two-row for size 1 with specific fan configurations.
Working Conditions
These coolers can operate with liquid temperatures up to 110°C and pressures up to 1MPa. They are equipped with three-phase electric motors and can include a control system for adjusting fan operation based on outdoor temperature and cooling needs.
Designations
Fan coolers are designated by size (1, 2, 3), number of fans, and number of heat exchanger rows. For size 1, options include 1W, 2W, 3W, 4W, and 6W fans, with II or III rows. Sizes 2 and 3 have 4W or 6W fans with III rows.
Technical Data
Technical specifications include air flow rates, basic dimensions, and weights for both II and III row heat exchangers. Single fan specifications cover speed, voltage, motor power, and current. Noise levels are provided for different configurations.
Cooling Performance
Rated cooling powers and liquid flow rates are given for specific ambient and liquid temperatures. Cooling power increases with higher liquid temperatures and lower ambient temperatures. Coefficients for adjusting cooling power based on temperature changes are provided.
Control and Automation
The control set includes a speed controller for automatic fan speed regulation, a control box for reducing fan operation, and a band temperature sensor. A manual and connection diagram are included, but short-circuit protection is not.

HEATING AND VENTILATION UNITS ВОЗДУШНО-ОТОПИТЕЛЬНЫЕ АГРЕГАТЫ CHW FAN COOLERS ВЕНТИЛЯТОРНЫЕ ГРАДИРНИ INTENDED USE Fan coolers are used for cooling liquid, mainly hot water, with outer air. They are used in plants, in manufacturing processes requiring cooling of cooling factors and in other objects where decrease of liquid temperature is needed. Coolers are fitted for outdoor assembly. Вентиляторные градирни CHW предназначены для охлаждения наружным воздухом жидкости, в основном воды. Применяются на промышленных предприятиях, в производственных процессах, и других объектах, где есть необходимость снижения температуры жидкости. Вентиляторные градирни устанавливаются снаружи здания. UNIT DESCRIPTION Series of types of the cooler includes 3 sizes with several fans placed in one or two rows in each. The cooler consists of: ›› fin heat exchangers ›› axial-flow fans ›› (casing) frames Coolers elements are made of copper pipes with outer diameter of 16mm, walls thickness of 1mm and aluminium ribs with spacing of s=2,5mm. Connectors in standard version are screwed. Heat exchangers has III rows (for all sizes) or II rows (only size 1 for 1W, 2W and 3W fans quantity). Fans may be placed in: ›› one row 1,2 or 3 fans ›› two rows 4 or 6 fans Модельный ряд градирен состоит из 3 типоразмеров, в состав каждой входят несколько вентиляторов, расположенных в одном или двух рядах. В конструкцию градирни входят: ›› ламельные теплообменники; ›› осевые вентиляторы; ›› корпуса. Теплообменники изготовлены из медных трубок наружным диаметром f16мм и алюминиевых пластин с шагом s=2,5мм. Патрубки в стандартном исполнении подсоединяются к системе с помощью резьбы. Теплообменники выступают в двух версиях: трехрядные (для всех типоразмеров) или двухрядные (только CHW-1- 1W, 2W, 3W). Вентиляторы могут быть расположены в: ›› одном ряду (1- 3 шт.); ›› в двух рядах (4 - 6 шт.). WORKING CONDITIONS УСЛОВИЯ РАБОТЫ Coolers may operate at liquid temperature of 110 C and at pressure of 1Mpa. Fans are provided with three-phase electric motors. Coolers may be equipped with device control system allowing for gradual attaching particular fans, depending on outdoor temperature and requirements of liquid cooling. В градирни может подаваться жидкость максимальной температурой 110OC и максимальным давлением 1МПа. Вентиляторы оборудованы трехфазными электродвигателями. Градирни могут быть укомплектованы автоматикой, дающей возможность постепенного включения вентиляторов в зависимости от температуры наружного воздуха и необходимой степени охлаждения жидкости. Fan cooler Size Number of fans Number of heat exchanger rows CHW-1 -3w -II 1; 2; 3 unit size 1: 1w; 2w; 3w; 4w; 6w unit size 2 and 3: 4w; 6w for unit size 1: II or III rows for unit size 2 and 3: III rows Вентиляторная градирня
