HC2 Gas Fired Heaters
Thermal Fluid Heating Systems
The pre-engineered HC2 thermal fluid heater is available in standard sizes from 500,000 to 100 MM Btu/hr. Configuration options include vertical up-fired, vertical down-fired, and horizontal. This system is skid mounted with a burner and integrated control panels.
To view all heater models, technical specifications, and standard dimensions download our pre-engineered HC2 brochure.
Sigma Thermal also offers custom thermal fluid heater designs for a wide variety of project-specific design challenges.
Pre-Engineered Design Features
Dual helical coil design with 3 flue gas passes along the coil
Liquid or vapor phase service up to 675°F
Flue gasses are significantly cooled, eliminating the need for most internal shell insulation
Vertical and horizontal configurations
The heater shell is externally insulated with mineral wool insulation and covered with aluminum cladding
High turndown gas or oil-fired burners for use with traditional or alternative fuel sources
Advanced control systems with standard configurations for simple and cost-effective control and for PLC-based control with HMI
Available option for economizers to increase thermal efficiency to 93% or higher LHV Basis
Option for ultra-low emissions burners meet the most stringent requirements
Option for alternative area classifications and code compliance such as CSA, ATEX/CE, etc
