heat-exchange-equipment

A heat exchanger is a technical apparatus in which heat is exchanged between two mediums having different temperatures.

Type of heat exchangers:

Shell-and-tube exchanger
Plate-type heat-exchanger (dismountable type, welded type)
Spiral-type heat exchanger
Submersible heat exchanger

Shell and tube heat exchangers benefit from a wide operating temperature range, resistance to pressure hammer, high efficiency, wear resistance, durability, maintainability, operational safety and the ability to operate in aggressive environments.

Gasketed plate heat exchanger:

Compact design
Competitive delivery time
Easy maintenance
High heat transfer efficiency
Resistant to contamination
High turbulence due to individual plate design
The gasket material enables multiple use

Welded plate heat exchanger:

Plate pack welding is fully robotised
Competitive delivery time (316L steel - 4 months; titanium, 254SMO, nickel - less than 6 months)
Reinforced frame elements to withstand mechanical expansion of the plates
No leaks in the corners of the plates
Comfortable design for maintenance (all sides open)
Operating pressure: vacuum…50 bar (g.)
Design temperature: -52 С ° …+400 С °
Min delta temperature inlet – outlet: 2 С°

Spiral-type heat exchanger:

No dead spots
Highly effective channel cleaning
High heat transfer coefficients in "difficult" medium
Channel geometry for maximum product removal
Circular shape completely eliminates stress on the components
Ideal for liquids containing solids, fibres, sludges, slurries and suspensions
Heat transfer area up to 800 m2
Design pressure: Vacuum...45 bar (g)

Submersible heat exchanger:

In the submersible coil heat exchanger, one heat transfer medium moves through a coil that is submerged in a tank with another heat transfer medium. The speed of the liquid in the shell side is negligible and hence the heat transfer from the liquid is comparatively low. These heat exchangers are used due to their simplicity and low cost in small installations.

Application:

Water/steam water condenser
Chlorine vapour condenser
Hydrogen (drying) cooling
TEG heat exchanger (thermoelectric generator)
Amine and glycol heat exchanger
Top condenser
Heater/cooler, liquor condenser
Raw bottom product heat exchanger
Cooling the ammonia water tank
Condenser of a rectification column
Produced water heat exchanger
Crude oil heat exchanger/cooler
Ethylene oxide/ethylene glycol units
Heat recovery units at refineries
Heat exchanger for primary refineries
Solvent/gasoline chiller
Also: pharmaceuticals, food industry, petrochemicals

Air-cooling unit (ACU)

General-purpose air cooling units (ACU) are heat exchange equipment and are designed for:

For cooling gases and liquids
Condensing steam and vapour-liquid medium in technological processes of chemical, petrochemical, oil-refining, oil and gas industry with medium pressure from 0,6 to 10 MPa (6 - 100 kgf/cm2) or under vacuum with residual pressure not lower than 665 Pa, temperature not higher than 400 C and viscosity at the outlet to 5*10 -5 m/s2.

The unit can consist of 3 horizontally arranged tube sections made up of finned bimetallic tubes. The sections are mounted on a metal structure. The fan wheel drive is placed on a separate frame. The fan wheel, rotating in the collector cavity, drives air through the inter-tube space of the sections, cooling the product. The cooled process product moves inside the bimetallic finned tubes, transferring the heat through their walls to the cooling agent. The cooling medium is atmospheric air. The units can be equipped with a humidifier, heater and louvers. Louvers are available with manual adjustment or automatic rotation of the shutters. The units can be equipped with recirculation system consisting of panels, upstream, downstream and side louvers. The recirculation device ensures that the air heated in the pipe sections is recirculated to prevent overcooling of the product in winter.

The following types of air coolers are available:

ACH- horizontal air cooling unit
ACZ - zigzag-shaped air cooling unit
ACS - small-flow
Package type designs
Units with recirculation of heated air

Applications:

Refining industry
Gas processing industry
Petrochemical industry
Chemical industry
Gas industry, etc.

Spray drying units

The spray dryer allows the production of powder products by water evaporation and can be used with solutions, suspensions and emulsions.Once the necessary operating parameters have been set, the dryer will be the solution to obtain powder products or fine sinter with fixed and constant characteristics (moisture, particle size distribution, density).

The process involves spraying the concentrated liquid to be supplied into small droplets in a chamber in which hot air is circulated.

Designed for any capacity required by the Customer;
Feed rates from a few hundred grams to over 100 tonnes per hour;
Continuous operation provided by fully automatic control;
Possibility of use with both heat-resistant and heat-sensitive products;
Spray drying system with fluidised bed and closed loop, turbine dryer, indirect heat exchanger, external fluidised bed and dust collector.

Applications:

Petrochemicals;
Pharmaceuticals;
Food industry.

Cooling towers and components

Cooling towers are considered to be the most efficient means of cooling water for industrial facilities worldwide. With economic and environmental factors in mind, it is always important to consider the fact that the construction and operation of evaporative cooling towers requires the use of sufficiently efficient modern fillings.

We offer a wide range of different types of cooling towers, with individual solutions for each individual Customer's project:

Fan cell-type cooling tower
Hybrid cooling towers
Natural draught cooling tower
Mini-cooling towers
Air condenser
