Heating Skid Systems
Introduction
A heating skid is a pre-assembled modular unit with a complete thermal solution designed for efficient heat distribution for pre-treating the fuel gases for turbine or process heating to regulate the temperature, pressure and flow rate of a process fluid before it enters the main process chamber.. These skid steer heater preheat fuel gases to a temperature above the dew point. Our heat exchanger skid technology delivers reliable performance in demanding environments, from asphalt processing to petrochemical operations. These skid load heaters can also superheat the fuel gas which is a process of heating the gas to a superheated state which prevents the condensation of fuel gases during the downstream process.
About Heating Skid Systems
Key Components of a Heating Skid System
- Electric heater bundle: An electric heater, such as a circulation, immersion, or tube heater, is used to heat the fuel gas over the hydrocarbon and water dew points in order to avoid liquid buildup in the turbine’s condensation chambers.
- Pressure vessel or housing for the heater bundle: They are enclosed spaces that can contain and hold gases, liquids, and vapors at pressures that are significantly higher or lower than those of the surrounding atmosphere.
- Heater operation control panel: An industrial control panel (ICP) is made up of two or more control and monitoring components, including network switches, programmable logic controllers (PLC), switches, main circuit breakers, and other components for electrical system operation.
- Temperature sensors: The temperature of the fluid or gas to be processed in a heating skid is measured by temperature sensors, which are electronic equipment.
- Pressure safety valve: They are used to maintain pressure in the event of a pressure overflow by releasing gases or liquids.
- Flow control valves: Liquid condensate is drained using a variety of valve types, including on-off, safety, and flow control valves.
- Power & instrument wiring: The purpose of power and instrument wiring is to link the different pieces of equipment so that the heating skid system may function properly.
- Skid basis for simple site installation: Temp skid is a system that offers a platform that makes it simple to move and install the whole heating system.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Heating Skid Systems.
There are many factors that influence the thermal capacity required for your application such as the desired target temperature; volume of fluid to be heated; acceptable heating time; and ambient conditions where the heating skid is located. Our technical group performs detailed heat loss calculations based on these specific parameters in your process to arrive at the correct thermal capacity. We manufacture heating skids with capacities suitable for both pilot projects and large-scale industrial applications.
Once a heating skid is properly engineered for your application’s requirements, it will accommodate the specified temperature range which in most cases is typically an ambient inlet temperature up to approximately 300° C or greater for specialty thermal oil service. When we engineer systems we take into account many factors including the thermal properties of the fluid being heated, limitations of the pressure vessel materials and also applicable safety margins.
The maximum operating pressure of the heating skid is determined by the design parameters of the unit’s components (vessel material, wall thickness, and design specifications). Standard heating systems are designed to operate between 10 and 25 Bar (150 – 360 psi). In addition to standard heating systems there are also custom-designed systems that can operate at higher than standard operating pressures. All skid loader heater meet ASME Section VIII and the European Pressure Equipment Directive (PED) and use appropriate safety factors.
Yes, every heating skid is custom built based on your application process to meet your installation requirements. Examples include different piping configurations, different materials, different types of sensors, and different control logic. Our flexible designs allow for compatibility to your existing facilities.
Every system adheres to ISO 9001-2015 quality standards, ASME Section VIII pressure vessel requirements, and applicable electrical codes. We gladly accommodate additional standards specific to your industry or jurisdiction.
