The devices are designed to cool viscous products (with a viscosity up to 2x10¯m2 / s); oil refining, petrochemical and related industries. The device consists of three horizontally arranged pipe sections, made up of finned bimetallic pipes. The structural feature of the apparatus is a reduced coefficient of finning φ = 7.8 with a diameter of the supporting tube of 38 mm. The sections are mounted on a metal structure. The drive of the fan wheel is placed on a separate frame. The fan wheel, rotating in the cavity of the collector, drives the air through the annulus, cooling the product.


General characteristics in accordance with GOST R 51364-99

The devices are designed to cool viscous products (with a viscosity up to 2x10¯m2 / s); oil refining, petrochemical and related industries. The device consists of three horizontally arranged pipe sections, made up of finned bimetallic pipes. The structural feature of the apparatus is a reduced coefficient of finning φ = 7.8 with a diameter of the supporting tube of 38 mm. The sections are mounted on a metal structure. The drive of the fan wheel is placed on a separate frame. The fan wheel, rotating in the cavity of the collector, drives the air through the annulus, cooling the product.

At the request of the customer, the unit can additionally be equipped with a humidifier, air heater, jalousie. Blinds are made with manual adjustment or with a pneumatic drive turning the dampers. It is possible to produce apparatus with a recirculation system consisting of panels, upper, overflow and side louvres.

The recirculation unit recirculates the air heated in the pipe sections to prevent the product from subcooling in the winter. Apparatus can be equipped with fan wheels made of composite materials, and electric motors - with speed converters. The use of converters leads to a reduction in power consumption and simplification of the design of the fan wheels by eliminating the installation of a pneumatic actuator for automatically adjusting the angle of installation of the blades and simplifying the maintenance of the fan wheels.

Type of climatic performance of apparatuses U1 and UHL1 according to GOST15150-69. The device is intended for installation in areas with seismicity of 7 and 9 points (SniP 11 -7-81) and high-speed wind pressure on IV and V geographical area (SNiP 2.01.07-85). Connecting and overall dimensions in accordance with TU 3612-008-0021 8880-2004
