Dutch households. The site of the buffer facility is located in an area of now defunct salt mines. Gasunie and Petrogas gas-systems, who are managing
a glycol dehydration and regeneration unit through BTE Technische Handelsonderneming, have chosen Tranter as their preferred supplier of welded plate heat exchangers. Petrogas Gas-Systems is a globally active turnkey gas facilities contractor and is also able to handle servicing and maintenance requirements.
All-welded plate heat exchangers are able to withstand both very high pressures and high temperatures. The contract in the Netherlands was awarded to Tranter due in no small part to the many advantages that welded plate heat exchangers have over tube heat exchangers. “Firstly, Tranter’s welded plate heat exchangers take
up significantly less space than the tube heat exchanger alternative, possibly as much as 50 per cent less installation space. Secondly, these welded plate heat exchangers require almost no maintenance at all, which of course is a major financial benefit in both the short and long term,” says Hans de Groof, head of the team responsible for Petrogas’ installation and implementation at Gasunie in Zuidbroek. The Petrogas installation at Gasunie’s nitrogen storage
facility is an advanced multi-pass solution with a long thermal length. In Tranter’s solution, glycol passes through the welded plate heat exchangers no fewer than five times. This ensures that the necessary process of regenerating glycol for the dehydration of the huge quantities of nitrogen involved is made as efficient as possible.
True dual evaporator for chillers SWEP has launched the DP700, a brazed plate heat exchanger with the function of an evaporator and condenser for chillers. It is designed for R410A chillers, with a cooling capacity range up to 700 kW. The DP700 enables high performance and low pressure
loss on the secondary side, and is short and compact which creates space for other system components. SWEP’s AsyMatrix plate design for high performance
is another feature of the product. The AsyMatrix channel configuration increases thermal performance, reduces refrigerant charge and decreases the pump power needed for the circulation of chilled media. Meanwhile the company also has launched its e-business

shop to the US market. This features fast and secure online orders, a user-friendly web interface, a delivery scheduling system and live expert advice from SWEP’s local support. “The shop provides a comprehensive overview of our products and accessories and makes it easy for our customers to plan their orders and deliveries. It makes the business of selling brazed plate heat exchangers easy,” said Pär Björkman, company segment manager dealer. ■
Precise repeatable tensioning O
ne of SWECO most recent technological breakthroughs, Fusion Screens, has a unitary construction
which integrates the screen gasket directly into the tension ring. This complex robotic construction creates precise repeatable tensioning and engineered uniform integral strain relief. The integral gasket, which is comprised of the gasket, strain relief, and screen frame are one moulded part.

The screen’s manufacture boasts no silicone/no adhesive as the mesh is fused into the screen frame and centre disc. Another recent innovation is the GyraMax Gyratory Sifter, which can increase your plant’s productivity by reducing the costs associated with routine maintenance and unscheduled repairs. Screen changes are quick
and easy, even for multi-deck screeners. With the GyraMax, you can change any screen at any level
of the machine from either end without disturbing the other screens or ball trays. Additionally, SWECO offers high speed
vibrating rectangular separators, high-capacity centrifuges, size reduction mills and replacement parts and screens for any piece of screening equipment in use today. ■
