Industrial Dampers for Refineries
Kelair dampers are essential to the safety and operational efficiency of systems used by petrochemical manufacturers and oil refineries.
Plant operators, engineers and management within the chemical process industry know the significance of precision, caution, and reliability of equipment to comply with environmental health concerns. Inefficient and uncontrolled systems releases unstable gases into the environment, disrupting the ecosystem and contaminating the air, food, and atmosphere. This processing of chemicals demands particular attention to pollution control through efficient and reliable equipment with Kelair dampers.
How are dampers used within refineries?
With increasingly stricter environmental regulations which mandate lower emissions, dampers are used by many companies within the oil/gas and petrochemical sector in a variety of circumstances, from offshore drilling rigs to gas compression systems. Refineries transport streams of fluids between chemical processing units which can create chemical emissions and odors. Kelair’s custom industrial dampers are designed and engineered to exceed even the highest safety requirements, and directly address challenges for optimal performance.
The dampers used within oil refineries and petrochemical plants must be designed and engineered in a way that helps companies maintain environmental conditions and pressurization between hazardous and non-hazardous areas. Dampers are used to dilute and remove potentially dangerous concentrations of toxic gases, filter dust and other chemical contaminants, and can also be used to isolate and control ventilation in case of an emergency.

Butterfly dampers have the simplest design and the fastest turnaround. They are the economical choice for applications ranging from light duty to heavy duty and low temperature to high temperature.
Kelair's Louver Dampers are applicable for light duty industrial ventilation to heavy duty, high volume flow control and isolation applications. Parallel or opposed blade, outboard bearings and linkage, adjustable packing glands and double skin airfoil vanes are all standard on louver dampers from Kelair.
Slide Gate / Guillotine Dampers
These types of slide gate or gullotine dampers are used primarily as shut off devices. Kelair's rugged, heavy duty designs are available round or square with sizes from 4" up to 96" making them an ideal solution for industrial applications.
Diverter & Tee Dampers
Diverter Dampers also called Tee Dampers are used to redirect air stream (hot gas or otherwise) from one outlet to another. These types of dampers are widely used in incineration systems to divert process air and gas to the incinerator or by-pass to the atmosphere.
Kelair’s Refractory dampers are manufactured to withstand temperatures up to 1900 F in corrosive, particulate and/or process gas environments. Refractory dampers from Kelair help reduce heat loss to surroundings and provide erosion protection for the frame.
Inlet Vane Dampers
Inlet Vane Dampers work with fans and blowers to enhance their performance by controlling air volume and fan shut-off. They can be mounted to the fan inlet to conserve power at reduced airflow. These types of dampers reduce fan pressure without reducing speed. Kelair’s design boasts no external linkage, eliminating pinch points and damage to the assembly.
Kelair’s Backdraft dampers are engineered to allow airflow in one direction and prevent reverse airflow. They are typically wall or roof mounted and applied to mechanical HVAC ventilation systems. Backdraft dampers control airflow in ventilation systems either to modulate or to shut off moving air through a fan opening when it is turned off. Backdraft dampers can utilize pneumatic or electric actuators or be gravity controlled.
Stack Cap Dampers
Stack Cap Dampers or Stack Isolation Dampers both isolate the stack opening to prevent foreign material from entering when not in use and conserve warmth when the stack is shut down or during maintenance. Kelair’s Stack Cap dampers deliver accurate air flow and isolation at high temperatures and high volumes, reducing the stack effect when offline thereby protecting ductwork from the elements.
