The CTH Superheated Water Heaters are our high capacity direct fired hot water heaters. A direct fired hot water heater imparts its thermal energy
directly into the process fluid, in this case water. The CTH utilizes a multi-tubular design composed of two distinct sections of heat transfer. The
combustion chamber, which is referred to as the radiant section, is fully encapsulated by parallel piped tubes running tangentially with the burner
flame. This chamber is place atop the convection section, where the exhaust gases pass through the convective section, continuing the heat transfer
The CTH has also been designed to be supplied with a variety of forced draft burners, provided by some of the world’s leading burner manufactures. This
allows us to utilize a variety of fuels, meet stringent emissions requirements and even allow our customers the opportunity to select the burner of
their choice. In addition, the CTH is constructed with several inspection doors to allow easy access to both the radiant and convective sections of
the hot water heater. This allows for a more thorough inspection and cleaning of the heater and internal pipes. If the combustion fuel is prone to
ash or unburnt particle generation a blower can be placed in the inspection doors to potentially help lessen the cleaning process.
The CTH Superheated Water Heaters come standard with an integrated combustion air preheater. The configuration of the combustion air preheater eliminates
the requirement for ducting between the two components, insulation for the preheater, and additional expenses for the installation of the combustion
air preheater. The simple addition of the combustion air preheater increase the efficiency of the heaters to upwards of 96%.
The CTH Superheated Water Heaters’ are designed and constructed to various local code requirements around the world. The most common codes are ASME with
National Board registration for the United States, CRN for Canada and CE/PED/TUV/DIN for Europe. Additional code requirements may be met if necessary.
Package systems are available for the CTH Superheated Water Heaters. These package systems can be customized to meet each of our customers’ needs, including
but not limited to: pump skids, expansion tanks, drain tanks, pipe spools, tank towers, ladders and platforms, and ancillary components.
