Shell & Tube Heat Exchanger – Industrial Heat Transfer Solutions A Shell and Tube Heat Exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher- pressure applications. As its name implies, this type of heat exchanger consists of a shell ( a large pressure vessel ) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes ( through the shell ) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes : plain, longitudinally finned, etc. ✕ ❮ ❯

  Fin Tubes – High-Performance Finned Tube Heat Exchangers A Finned tube heat exchanger will typically have tubes with fins attached to the outside of them. There will finned tube square usually be a liquid flowing through the inside of the tubes and air or some other gas flowing outside of the tubes, where the additional heat transfer surface area due to the finned tube, increases the heat transfer rate. For a cross flow fin tube exchanger, the fins will typically be radial fins either circular or square, as shown in the pictures ✕ ❮ ❯

Expansion Bellows – Metal Expansion Joints for Industrial Piping Systems Expansion joints are often included in industrial piping systems to accommodate movement due to thermal and mechanical changes in the system. When the process requires large changes in temperature, metal components change size. Expansion joints with metal bellows are designed to accommodate certain movements while minimizing the transfer of forces to sensitive components in the system. ✕ ❮ ❯

Evaporator & Condenser Coils – Efficient Heat Exchange Solutions Evaporator coils contain the system’s refrigerant as it converts from liquid to gas. The refrigerant moves through an expansion valve and into the evaporator coils. Heat transfer occurs in these coils, creating a cold surface. The blower moves air across the cold surface, creating the conditioned air that cools your home. The gaseous refrigerant moves to the outdoor unit. Condenser coils in the outdoor unit house the refrigerant during its return to liquid form. The compressor increases pressure on the gas, using it to condense into liquid. The heat is dispersed into the air outside. The liquid refrigerant moves back inside for the cycle to begin again. There is really no difference between a Hot water coil and a Chilled water…

Industrial Dust Collector Systems – Air Filtration & Pollution Control A Dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high – volume dust loads, a dust collector system consists of a blower, dust filter, a filter – cleaning system, and a dust receptacle or dust removal system. It is distinguished from air cleaners, which use disposable filters to remove dust. Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams, or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere. Dust collection is an online process for collecting any process – generated dust from…

  Blower wheel - Centrifugal, Axel Fans & Pump Impellers Blowers are machines whose primary function is to provide and accommodate a large flow of air or gas to various processes of many industries. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine. We fabricate Blower Units from the smallest size up to the largest size according to the CFM of it or original specification, modification by the customer requirement. We used material such as Stainless steel, Aluminum, mild steel and Zn coated. ✕ ❮ ❯

  AHU & HVAC System Solutions Expert Heating, Ventilation and Air Conditioning Services Heating, Ventilation and Air Conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC & R or HVACR. In some contexts "ventilating" is dropped (shown as HACR). ✕ ❮ ❯
