BABCOCK WANSON LAUNCHES NEW ELECTRIC THERMAL FLUID HEATERS
sterilisation temperature, a comparative hydroformed valve body reaches the mark in just over four minutes, and this difference can significantly speed up production turnaround.
OPTIMISING SUSTAINABILITY
A hydroformed design also reduces the steam requirement, and hence energy use, necessary during SIP. This can represent a significant cost saving, especially when multiplied across all installed valves. As hydroformed valve bodies can be as much as 75 per cent lighter, this also saves costs in installation with fewer supporting structures required.
This energy saving also provides an advantage in sustainability. According to the independent verifier, Trusted
Footprint, comparing 1” tubing, up to 38 per cent less gCO2 equivalent can be saved by using a hydroformed design, like the Bürkert Tube Valve Body, rather than a forged variant. Taking carbon emissions in valve body manufacture into consideration, hydroforming is also far greener. For a 1.5” device, Trusted Footprint confirms that the Bürkert Tube Valve Body generates 58 per cent less emissions in carbon dioxide equivalent during its manufacture, which includes steel production as well as processing techniques, compared to a forged body of the same size.
RELIABILITY AND HYGIENIC CONFORMANCE Although cost saving and sustainability improvements are highly important, valve body performance is fundamental. To ensure optimum durability, the design and manufacturing techniques of the valve body have to meet burst and leak pressure specifications. A safety factor multiple times the required real- world level can be achieved through the hydroforming and annealing processes, combined with the necessary conformance in wall thickness. It’s also essential to ensure that any welding can withstand the sudden temperature changes of sterilization and cooling, as well as resistance to cracking under vibration. Equally crucial is hygienic conformance. 316L stainless steel achieves this, and the design, including weld lines, has to remain corrosion-free under intensive saline testing. Ultimately, a material inspection certificate 3.1 according to EN10204, with a CIP-capable design that meets EHEDG Type EL, CLASS I Certification, as well as 3-A Sanitary Standards, create trust in hygienic conformance.
MEETING STANDARDS IN SUSTAINABILITY While reliability and hygienic conformance should be a given in specification, optimising valve body design can not only increase productivity but can also enhance sustainability. Lower energy use in operation, in addition to the lower carbon emissions in valve body manufacture, can help provide a pharma, food and bev, or cosmetics manufacturer with the sustainability credentials they need from a supplier. Integrating light, strong tube valve bodies, these producers can reduce costs in production as well.

Industrial process heating equipment and solutions specialist Babcock Wanson has launched the EPC EL range of electric thermal fluid heaters, providing customers with an effective low carbon process heater with no direct emissions. The key functionality required by thermal fluid heaters are high turndown, low heat flux, accurate temperature control and high safety level which is incorporated in the design.
heating elements inserted within the carbon steel exchange tubes where the thermal fluid circulates at high velocity, the EPC EL ensures a precise forecast of the fluid temperature at each point of the thermal fluid internal path, with no internal significant recirculation. The 1-D fluid arrangement allows for a more compact volume and greater protection of the thermal fluid when compared to a single vessel design, for improved fluid longevity. Modular in design, EPC EL electric thermal fluid heaters can be configured in series and parallel to meet different applications and site requirements. The single functional unit is composed of two thermal heater elements, each with a maximum power of 60kW. In the event of a thermal heater failure, the EPC EL can continue to operate at reduced power, excluding only the faulty element. A single 100 A thyristor controls the power, for flexibility and modulation. For temperature limitation the heating elements are equipped with temperature sensors, connected directly to the surfaces of the heating elements. The EPC EL is supplied with a
A
multi-tubular type thermal fluid heater, with a series of flanged electrical
separate power and control panel housed in a standard cabinet for ease of access. The panel is fitted with PLC with HMI for simple and clear operator interface. As with all Babcock Wanson process heaters, the EPC EL is extremely durable and easy to maintain. Inside the casing the tubing is fully welded to prevent leakage points. The heating section is installed inside a protective steel frame housing, closed by thermal insulating sandwich panels which are easily removable for inspection. The front of the heater, where the electric elements are located, is protected by a light cover, fitted with fast release bolts and handles that can be lifted by a single operator. The EPC EL is the latest addition to Babcock Wanson’s range of thermal fluid heaters, which include heaters with integrated gas, oil or dual fuel burners to meet the needs of modern industry.
