Alternative solutions for energy efficient process heating and hot water Hospitals all over the UK have been utilising ARI-Armaturen’s impressive range of engineered systems. ENCOsys® plate heat exchangers have been a major solution for companies looking for a proficient heating and hot water system that will ensure a secure and economical future for their site be approximately seven per cent more energy efficient when compared to a basic shell and tube heat exchanger. One of the most significant savings however, is that unlike shell and tube heat exchangers, ENCOsys® does not need to be stripped down for insurance inspections allowing for further cost savings, reduced downtime and dramatically improved health and safety risks associated with this work.
With so much pressure to reduce spend and improve energy efficiency measures, many organisations have been forced to adopt demanding targets to cut greenhouse gas emissions and are therefore looking for alternative solutions to update energy and heating systems. Reliable and resourceful systems Offering reliable and resourceful systems with considerable savings in energy and cost (when compared to more traditional systems such as shell and tube calorifiers), ARI-Armaturen’s ENCOsys® is a compact, low maintenance steam-to-water plate heat exchanger. Suitable for various applications including domestic hot water, low temperature hot water, and process heating, these innovative units are currently in operation in many healthcare sites and hospital plant rooms over the UK. Designed to provide hot water instantaneously whatever the load conditions up to 2100kW, there is no need for a water storage vessel. Having

no water storage vessel is an added advantage because it also helps to eliminate a potential breeding place for Legionella and other bacteria’s, therefore reducing the requirement for regular inspections. Sites with ENCOsys® units installed benefit from improvements to operating efficiency with reduced heat loss from equipment, improved temperature control as well as better thermal efficiency, all resulting in vast improvements to operation efficiency and energy savings. This system is more responsive to changes in the secondary operating conditions resulting in far tighter temperature control. Generally, the water temperature leaving shell and tube heat exchangers tend to cycle in a pattern similar to a sine wave which means the temperature set point may have to be set higher to ensure the unit meets the required load at all times. By using the ARI-ENCOsys®, temperature control is considerably improved, typically providing an estimated three per cent energy saving. Based on these factors, ENCOsys® can

Compact design Another benefit of the ENCOsys® heating systems is that the physical design is extremely compact, with the largest unit occupying around 3m3 and the smallest unit occupying less than 1.5m3 resulting in a smaller footprint than many other alternatives on the market as well as allowing for significant savings in valuable floor space. Nicholas Davies, ARI-Armaturen UK Ltd sales director, said: “By heating the secondary water and sub-cooling the condensate in the same plate heat exchanger, substantial energy savings can be achieved and the cost of ownership is further reduced because improved energy efficiency means lower fuel bills and low CO2 emissions.” ARI-Armaturen boast a wealth of knowledge and technical experience in energy management systems so from assessing your initial requirements, through to conduction of surveys to final commissioning, the installation process can be completed in a short timeframe, leaving you rest assured that you have been provided with a quality product and quality service. This range of well-engineered, packaged solutions from valve specialists ARI-Armaturen UK Ltd come fully assembled to specific requirements and tested ready for connection.
