QLKE and QDKE - Single Tube Cooler
.webp)
overview
QLKE
The QLKE single tube cooler is made of 1/2” (12,7 mm) tubes with a circuit sized for the conditions of the cooling water. The tubes are mounted in a bundle of aluminum or copper fins.
QDKE
The QDKE single tube cooler is made of 15mm tubes with a circuit sized for the conditions of the cooling water. The tubes are mounted in a bundle of aluminum or copper fins.
Removable Header
To assist with the mechanical cleaning of the cooler, the coil body is fixed between tube plates with a removable header (water box). The header is also equipped with drain and venting plugs. Headers can be made of Rilsan® coated steel, stainless steel, or titanium.
The cooler may be internally cleaned by simply removing the headers and using a brush (accessory) inside the tubes.
Technical Information
Tube specifications
- Available tube materials are copper, copper-nickel (90/10), stainless steel or titanium.
- The tubes are mechanically expanded into the fins to give absolute contact between the two materials.
Fin specifications
- The standard fins are aluminum, but can also be copper that resists a saline environment very well.
- The fins on the tubes give an increased heating surface to compensate for the low heat transfer coefficient on the air side.
- The pitch between the fins is selected to get required cooling duty and air pressure drop conditions.
