Fluid heater for ships
(horizontal) GEA Bloksma

The Bloksma oil & water heater has a removable tube-bundle with U-bends. This construction allows a free expansion of the tubes. The tube sheet is bolted between two flat gaskets. U-bended seamless drawn tubes (St. 35.8) are roller expanded into the tube sheets. In case of thermal oil the tubes are additionally seal-welded. The cover is provided with welded flanges according to ISO or (compact) SAE norms to reduce space-requirements. This SAE connection is preferred by module-builders.

The standard version of the heater is made of mild steel. Other materials, such as stainless steel and copper-nickel with coated cover and coated intermediate ring are possible. All steel parts are shot blasted and painted with a layer of heat-resistant aluminium coating, silver coloured RAL 9006.Heaters are supplied with a rust-preventing layer for storage up to 6 months. Insulation (optional) by mineral wool mats, covered with galvanised steel plate. Alternative constructions are available for use as tank-suction heater or tank heater
