Heat Exchangers Improving Efficiency and Reducing Emissions
SPX Flow heat exchangers provide easy inspection and maintenance access and can be cleaned using clean-in-place (CIP) or mechanical cleaning processes. The high thermal efficiency of APV heat exchangers enables a very compact design, resulting in a minimum footprint where space and weight are essential parameters.
June 2018 saw the launch of the latest addition to the APV portfolio of plate heat exchangers. The exciting 2" ported Mira unit offers the best thermal performance yet within the APV range. This means less extensive load bearing foundations, faster installation at lower cost and lower overall capital expenditure.
According to the company, the range of APV gasketed plate heat exchangers offers exceptionally high thermal efficiency with the flexibility to reconfigure solutions to meet changing needs. Plates are designed for efficient flow distribution and optimum turbulence to maximise heat transfer efficiency. Service downtime is minimised due to easy operation and maintenance features including easy-to-mount APV clip gaskets and plate alignment features such as ‘Corner Lock’ and ‘Bubble Lock’ which ensure a stable, well-aligned plate pack every time the unit is closed.
In higher temperature and higher pressure applications, the APV Hybrid series of welded plate heat exchangers stand out as an obvious choice. The high thermal efficiency of the APV Hybrid heat exchangers reduces external energy input demand, while its design flexibility enables very low-pressure drops to be achieved without compromising performance.
The firm adds that optimised plate corrugation patterns reduce the risk of fouling and increase heat recovery respectively, depending on the duty conditions and priorities. The Hybrid heat exchanger can be easily opened for inspection and cleaning by removing the housing covers. The unit is mechanically cleanable on the tube side and plate side is easily CIP-able making it a truly cleanable solution.
In relation to the APV Paraweld series, these semi-welded plate heat exchangers are designed with welded channels to allow handling of aggressive fluids and are available with either conventional or special gaskets to match specific duty requirements. The units are highly suitable, functioning as main propane pre-heaters and propane evaporators, explains the company.
Also available is the Orion Duraflow & Energy Saver, a 4" ported plate heat exchanger designed to cover a wide range of applications and secure even better solutions for customers in the energy sector. By implementing features developed over the past ten years it delivers a more cost effective heat exchanger with a superior ratio between plate thickness and pressure rating. The superior plate stack stability enables the use of thinner and more efficient plates without compromising mechanical strength, claims the firm.
Improved thermal performance is achieved through the graduated chocolate box distribution. The Orion plate exchanger allows improved construction time as maintenance is reduced to a minimum. Any service required can easily be carried out by the staff on site, saving both time and money.
