Product catalog summary
Overview
EXHEAT provides comprehensive solutions for hazardous area electrical process heaters and control systems. Their services include Computational Flow Dynamics (CFD) and Finite Element Analysis (FEA) to optimize heater design and performance.

Key Analysis Areas
  • Normal Operation Thermals: Ensures optimal heater design, including baffle pitches and sensor placement.
  • Low or Zero Flow Fault Condition: Simulates scenarios where reduced flow causes overheating, identifying critical flow rates and maximum shell temperatures.
  • Heat Loss and Design Temperature: Evaluates heat loss along outlet pipes and selects appropriate design temperatures.
  • Tank and Room Heating: Analyzes tank heat-up times and room heating requirements, considering ambient conditions and structural losses.
  • Air Duct Heater Pressure Drop: Assesses pressure drop and air cool-down in ductwork.

Computational Solutions
EXHEAT's CFD/FEA studies assist in the early stages of project design, ensuring tailored thermal requirements and efficient heater specifications. These analyses extend beyond heaters to include upstream and downstream pipework, confirming design adequacy and insulation effectiveness.

Visualisation and Reporting
Advanced post-processing capabilities allow for clear visualization of results, such as velocity, surface temperatures, and pressure variations. Comprehensive reports detail simulation inputs, outputs, and calculated results, aiding in design adjustments.

Available Solutions
  • Normal Operation: Simulates heater performance under standard conditions.
  • Low or Zero Flow Condition: Identifies critical conditions leading to over-temperature trips.
  • Upstream/Downstream Analysis: Evaluates temperature and flow profiles in connected pipework.
  • Tank Heating: Provides analysis of tank warm-up and holding duties.
  • EXHEAT Cast Heater: Offers quick analysis for standard Cast Heaters, with potential cost refunds upon purchase.
  • Duct Heating: Analyzes pressure drop and air temperature changes in duct systems.
  • Room Heating: Calculates heating requirements considering structural losses.

Computational Flow Analysis-1

Hazardous Area Electrical Process Heaters & Control Solutions Computational Flow Analysis EXHEAT’s all-encompassing Computational Flow Dynamics (CFD) and Finite Element Analysis (FEA) offers a variety of computational solutions for your process analysis requirements. By utilising CFD/FEA studies during the early stages of a project, be it pre-FEED, during the main FEED study or detailed design stages, EXHEAT can assist with tailoring your thermal requirements and assisting with the design and specification of your process heaters. Should this lead to an order for our heaters, EXHEAT would be able to provide the heater as designed in a timely manner due to the prior involvement. The analysis are not limited to just EXHEAT heaters but can be increased to include upstream and downstream pipework to confirm acceptable design, whether there is enough insulation to maintain a process temperature or if adding some additional pipework will increase the pressure drop. Slice: Velocity Magnitude (m/s) TYPICAL ANALYSIS The advanced post processing capability that EXHEAT can offer will allow you to clearly visualise the results, whether they show the velocity through a heater, the surface temperature of elements or even pressure variance due to the baffled flow design implemented on many heaters. Normal operation thermals Low or zero flow fault condition Heat loss along an outlet pipe Design temperature selection Tank heat up time or running temperatures A comprehensive report will be produced that provides details of the information used to run the simulation, including process and geometry, output values, tables or images, depending on the analysis completed. Each report will be tailored to the analysis run and offer calculated results which can be used to affect the design of the heater or pipework should they be required to.

Computational Flow Analysis-2

Hazardous Area Electrical Process Heaters & Control Solutions EXHEAT has already utilised the simulation packages to refine the design of process heaters by ensuring items such as the baffle pitches are optimised for the specific process, element temperatures remain at acceptable levels under normal operation, and the heat transfer is sufficient for process requirement. AVAILABLE SOLUTIONS Normal Operation EXHEAT can simulate a heater running in normal operation and demonstrate that the appropriate design has been created for the heater. This will include such things as baffle pitches and form...
