Complementary Equipment

Everything the cooling circuit needs besides the radiator is selected with it, so the whole circuit is delivered as one coordinated package.

Complementary equipment

Plate Heat Exchangers

Plate heat exchangers transfer heat between two separate fluid circuits in a very small volume. In engine and cogeneration plants they separate the radiator circuit from the engine or process water, recover heat for district heating and protect the engine circuit from the quality of the external water.

• Gasketed or brazed plate packs selected for the duty, the temperatures and the allowable pressure drops of both circuits.
• Plate and gasket materials chosen for the fluids: water, glycol mixtures, oil or process water.
• Supplied with the radiator or mounted on the heating module skid with the pumps and valves of the circuit.

Complementary equipment

Shell & Tube Heat Exchangers

Shell-and-tube heat exchangers carry high pressures, high temperatures and fouling fluids that plate units cannot. They are used where the duty, the fluid or the cleaning requirement calls for a robust tube bundle.

• Tube bundle, shell and headers designed for the duty and the design pressure and temperature of both sides.
• Tube materials selected for the fluids and the cleaning method.
• Supplied loose or integrated into the cooling package with the radiators and the auxiliaries.

Complementary equipment

Oil & Fuel Coolers

Engine lubricating oil and return fuel must be kept within the temperatures the engine manufacturer specifies. TECS builds fan-mounted oil and fuel coolers in its own factory, sized for the heat to be rejected and the site ambient.

• Finned-tube coils for oil or fuel with electric fans, frame and connections.
• Sized for the heat rejection, flow and allowable pressure drop given by the engine manufacturer.
• Delivered as stand-alone units or integrated with the main radiator.

Complementary equipment

Expansion Tanks

The expansion tank takes up the volume change of the coolant between cold start and full load and keeps the circuit filled and pressurised. TECS sizes and builds the tanks for each radiator and circuit.

• Stainless-steel tanks in SS304L or SS316L.
• Sized for the coolant volume of the radiator and the circuit and for the operating temperature range.
• Filler neck, pressure cap, sight glass, level switch and connections as required.

Complementary equipment

Control Panels & Junction Boxes

Every TECS radiator leaves the factory with its fans wired. Junction boxes and control panels bring the motors, isolators and signals together in one place for the site electrician.

• Junction boxes with isolators per fan, or control panels with starters, protection and speed control.
• Enclosures and cable glands to the IP rating and the site atmosphere.
• Wiring and function tests at the factory.
