Packaged Thermal Fluid Heaters The HI-R TEMP® Line
Flow Diagram
Operating Concept
The HI-R-TEMP thermal
fluid heater is a forced circulation water tube design in which
thermal fluid under pressure circulates through a set of nested, parallel
connected coils while forced draft combustion gases travel across
the coils. The hot gases envelope the entire tube surface making maximum
use of both radiant and convective heat to achieve very high heat
transfer rates.
A recirculating pump is selected to give the proper flow rate and
pressures for each application to optimize motor horse power required
while maintaining low film temperatures to ensure long fluid life.
Temperature controls monitor the output temperature and regulates
the supply of fuel and air to the burner and provides efficient combustion
over the complete modulating range of the heater. High efficiency
is maintained, without thermal shock, over the full operating range,
not only at high fire.
The high velocity flow and small fluid volume in the unit result in
immediate response to load changes.
The built in safeguards which monitor the flame and other safety interlocks
assure maximum operational safety of the heater.
Marine Design
Vapor offers a specialized version of this heater for the marine environment.

Controls
An integral control panel contains all controls
and indicators necessary for the safe operation of the unit. A programmed
operating sequence is also incorporated for simplified startup.
Free Start-Up Service
A qualified service representative is on hand for two consecutive
days during start-up to assure trouble-free operation and provide
on-site operator training.
Built to Meet Standards
Every unit is built to ASME Standards, Hartford inspected and National
Board registered. Coast Guard, American Bureau of Shipping, Factory
Mutual, Industrial Risk Insurers, Lloyds and other approvals are also
available upon request.
Factory Tested
All units are fire tested for up to three days at the factory, with
their individual controls to assure proper operation and to allow
for control adjustments, which avoid installation delays.
