HC2 Thermal Fluid Heaters

The HC2 Gas fired thermal fluid heater is available in standard sizes from 1 to 100 MM Btu/hr. Configuration options include vertical up-fired, vertical down-fired, and horizontal. Custom heater designs are also available to meet a wide variety of project-specific design challenges. Sigma Thermal also offers HC1 gas fired thermal fluid heaters, biomass-fired thermal fluid heaters as well as options for electric process SHOTS electric heaters.

Design Features

  • Designed to meet all area classifications and to endure harsh environments, including offshore, arctic, and deserts
  • Capacities from 1MM to 100MM Btu/hr – custom sizes also available
  • Advanced control system options – Sigma Automation
  • Double helical coil design for three passes of flue gas along conservatively designed coil surface area
  • Base efficiencies can exceed 88% (LHV Basis) depending on process inlet temperatures, and with an optional economizer can exceed 93% (LHV basis)
  • Flue gasses are significantly cooled, eliminating the need for most internal shell insulation
