Oil & Gas

Delta T Thermal Solutions provide welded and spiral heat exchangers that meet the demands for the oil and gas industry. PLATECOIL®, MAXCHANGER® and ECONOCOIL® provide strong resistance from corrosive media, two-phase mixtures, extreme pressures, and intense temperatures. Furthermore, these heat exchangers can be exceptionally compact. Delta T offers all major types of calculations and stability analysis, including motion load, wind load, seismic load, nozzle load, and finite element analysis calculations if required. 

Oil & Gas Production and Refining

  • Optimization of heat recovery, cooling, condensation, dehydration and reboiling systems
  • Distillation column exchangers: fractionators, hydrocrackers, recrackers and hydrogen sulfide strippers
  • Waste heat recovery and feed water heating 
  • LPG reliquefaction

PLATECOIL® Prime Surface Plate Heat Exchanger Panels and Packages

Multi-Zone PLATECOIL® Prime Surface Heat Exchangers excel in steam heating applications.

PLATECOIL® banks find widespread use in tank heating applications to optimize pumping of heavy fractions.

PLATECOIL® Prime Surface Plate Heat Exchanger panels are made from die-formed channels pressed into flat sheets. Panels are then fabricated into pre-engineered modules, complete with piping, supporting structure and manifolds, or formed into vessel shells or jackets. Embossing pattern and number of panels are functions of capacity and pressure drop specified for the application. Two embossing patterns are used in oil and gas applications:

  • Multi-Zone PLATECOIL® provides uniform heating when using steam, especially with high flow rates and where low pressure drop is necessary. 
  • Serpentine PLATECOIL® offers high heat transfer capabilities at low-to-moderate flow rates for heating or cooling of liquid phase mediums.

As integral, one-piece units, PLATECOIL® banks comprise a rugged, high-strength design well suited as suction heaters and tank heaters for use with viscous products. There are only two connections, one inlet and one outlet, to make in the field.

Heating Crude Oil To Remove Sand And Water

Emulsions of viscous crude, water and sand are heated with steam or glycol using PLATECOIL® heat exchangers in treater tanks to remove the sand and separate produced water.

Crude Oil Desalting

Emulsions of viscous crude, water and sand are heated with steam or glycol using PLATECOIL® heat exchangers in treater tanks to remove the sand and separate produced water.

Waste Liquids Heating

The treatment of waste products for pollution control purposes at refineries requires heated tanks. PLATECOIL® exchangers are versatile products for these requirements. Steam heats the waste mixture, reducing its viscosity to facilitate the settling out of solids. Large surface areas, as required, can be provided by a combination of internal and external PLATECOIL® units. This also permits easy zoning of the heating surface.

Storage Tank Heating

Storage Tank Heating

PLATECOIL® units configured as suction heaters warm viscous products prior to pumping to speed unloading and save energy. PLATECOIL® heaters are also clamped on externally, allowing total accessibility. When heating sensitive lube oil, an air gap is provided to prevent overheating. 


MAXCHANGER® single- and multiple-pass designs fit virtually any application requirement. The unique geometry of the patented MAXCHANGER®’s variable interspaces produce extremely high “U” values. Channels formed between the specially dimpled, welded plates direct the two heat transfer media countercurrently through alternate paths for maximum efficiency, immediate thermal response and a close temperature approach capability of less than 1°C (2°F). These welded 316L SS or titanium units, rated to 70 barg (1,015 psig) and 538°C (1,000°F). 

Constructed for Long Life Cycles

The 1-mm (0.039-in.) thick dimpled heat exchanger plates are sandwiched between top and bottom plates specified to withstand the design pressure. Special spacers separate the plates, isolating the channels and establishing countercurrent flow. Four corner angles (or half-pipes) are welded to side plates, top and bottom plates and to the heat exchange plate points, forming inlet and outlet headers.

The corner angle fittings or corner half-pipe fittings, enable inlets and outlets—NPT or flanged—to be located in any number of configurations for maximum flexibility in tight spaces.


PLATECOIL® and ECONOCOIL® Bayonet Heater are great for tanks because you can put it in an existing tank without having to modify the tank.
