drop. The relative high pressure drop maintains channel velocity and shear stress at a high level, thus reducing maintenance requirements - which is important for the wastewater. Tranter is involved in another heat exchange project at
Gävle Hamn, which has a strategically important location just 170km from Stockholm and a catchment area that extends from Uppland and Dalarna northwards..
Aviation fuel
Among other things, Gävle Hamn has, for some time, been supplying Arlanda airport with all its aviation fuel directly by train. One train replaces just over 30 tank trucks, which previously transported the fuel through Stockholm up to Arlanda. Gävle Hamn has total storage capacity of 950 000m3
in around 140 tanks. The large oil and chemical tanks in the port have
previously been heated with fossil fuel in the form of oil. This relatively expensive method of heating is now being replaced with green district heating. The district heating specialist Palmat System chose
Tranter’s plate heat exchangers for the order it received from Gävle Rörteam, which is installing the district heating in Gävle Hamn. “Tranter represents cutting edge technical knowhow.
Combined with their fast, reliable deliveries, this is a decisive competitive advantage in our customers’ eyes,” says Per-Arne Tönners of Palmat System in Stockholm. In other heat exchanger news, SWEP has developed
an SMO 254 steel version of its DP300 brazed plate heat exchanger (BPHE). The DP300 is already available in AISI 304 and AISI 304/316 steels, and the company says that this new high-molybdenum SMO 254 model gives customers even greater flexibility in their choice of materials for demanding applications. SMO 254 offers higher resistance against corrosion, for eample in cooling towers and ground source heat pumps where a high chloride content in the water can be an issue.
Flexible chillers
The DP300 is an efficient and versatile true dual BPHE optimised for the environmentally preferred refrigerant R410A. The DP300 is a natural choice for flexible chillers and climate control applications, where its ability to offer full performance at both full- and half-load is a major advantage. In 2010 the company won the Frost & Sullivan Europe
Market Share Leadership Award in the BPHE market after capturing nearly 40 per cent of the market. SWEP has continually focused on improving the heat
transfer capability of its products. Enhanced material selection, such as the use of new types of stainless steel, has increased product resistance to corrosion. The company’s primary focus has been on three business
segments: air conditioning, heating and refrigeration. It is also actively trying to convert the technology used in S&T exchangers - which are used widely in air conditioners - for use in BPHEs. It is looking to replace the traditional use of other PHEs in heating applications with appropriate brazed heat exchangers that are more effective, compact and reduce the overall size of the system. l
