Where It Works
Thermal Transfer
Thermal transfer is the movement of heat from one fluid, gas, or surface to another to either heat, cool, condense, or vaporize a process stream. In industrial applications, thermal transfer is essential for controlling temperatures, improving energy efficiency, and maintaining consistent process conditions.
Example products
After cooler
CO2 condenser
Coolant water cooler
Gas compressor intercooler and aftercooler
Gas fractionation condenser
Glycol cooler
Lube oil cooler
Natural gas cooler
Overhead condenser
Product and rundown cooler
Propane condenser
Reactor effluent cooler
Refrigerant condenser
Heat Recovery
Heat recovery is the process of capturing waste heat that would otherwise be lost and reusing it for a beneficial purpose elsewhere in a facility or process. Instead of allowing hot exhaust gases, steam, or process fluids to release their energy into the atmosphere, heat recovery systems transfer that thermal energy to another stream, reducing fuel consumption and improving overall plant efficiency.
Example products
BFW heater
CO2 superheaters
Crude preheat exchanger
Feedwater heater
Gas/gas heat exchanger
Instrument air dryer regen heater
Methanator feed heater
