Unicrimp adds OB41 Anti-Corrosion Zinc Galvanising Spray


U


nicrimp, a leading supplier of


cable accessories, has further enhanced its market-leading OB41 portfolio of sprays and cleaners, with the addition of the Anti-Corrosion Zinc Galvanising Spray. This product offers an effective solution for cold galvanising of welded fabrications and metal structures that are susceptible to rapid corrosion without adequate protection. The OB41 Zinc Anti-


Corrosion Galvanising Spray is perfect for galvanising steelwork, pipework, and other metal surfaces that have undergone welding or modification. It is particularly useful for re-galvanising safety railings, fencing, and areas where the original coating is deteriorating due to aging or wear and tear. The spray creates a protective layer that resists flaking, chipping, discolouration, and abrasion, ensuring long-lasting durability. Additionally, it can be used as an industrial undercoat for steel, cast iron, or wood prior to painting, making it a versatile solution for a range of applications.


How to use: 1. Shake the can well for 2 minutes before use. 2. Surfaces must be clean, dry, grease and dust free. 3. Spray from approximately 15 cm away for even coverage. 4. After use, invert the can and spray to clear the nozzle.


The spray is touch dry in 15-30 minutes and fully cures within 16 to 24 hours. It also boasts a 36-month


shelf life from the date of manufacture, offering long-term usability. More information can be found on the Unicrimp website

City Plumbing continues expansion of Solfex range with heat pump accessories


C


ity Plumbing has introduced a range of cost-effective heat pump accessories including cylinders, diverter valves, feet and fluid to its exclusive brand Solfex, providing installers


with all they need to complete renewable installations with ease. With a long history of innovation in renewable energy


technology, the Solfex air source heat pump installation accessories build on the specialist range of solutions already available in City Plumbing branches. The new range includes Solfex’s unvented heat pump cylinders, which feature a high-flow, high-gain, full bore coil design to provide superior performance. The Solfex cylinders are supplied with all the required components and controls to provide seamless compatibility with the majority of heat pumps, and all come with a 10-year warranty. Solfex’s diverter valves have high kV, ideal for high flow rates.


They feature motorised valves, are compact and easy to install. The new heat pump feet range provides a variety of options


to best fit the installation needs. This includes pairs of premium 600mm feet with integrated spirit levels for correct positioning, through to the flexi foot kits, designed to support heat pumps by providing a sturdy base whilst preventing vibration transmission to the ground. The new range of heat transfer fluids offers key functions, including low viscosity and high thermal conductivity for optimised heat pump performance. The fluids are biodegradable, non- hazardous and contain a specially formulated biocide and an additive to increase thermal stability. The Solfex brand, which is nearly 20 years old, has its roots in the renewables market and has flourished over the past two decades and expanded its offering to encompass a broad range of sustainable technologies. With a background in installation, the Solfex team has meticulously curated its offering, ensuring that everything is easy to install, user-friendly, and suited for the UK market. Hemal Morjaria, Managing Director - Heating and Renewables at City Plumbing, says: “This


extension of the Solfex range to include wider renewable solutions demonstrates our constant evolution as a business. “City Plumbing is focused on providing high-quality, cost-effective solutions for installers as we move


towards more sustainable energy solutions, so widening the Solfex range into air source heat pump accessories means our installers can have the convenience of being able to access all the products they need from one location.”

FERNOX POWERS A QUICK RECOVERY BY HELPING SOLV GROUP RESTORE HEAT FAST


F


ernox recently assisted solv group in restoring a broken-down boiler for a customer in Belfast. After being approached by the mechanical, electrical and facilities management service provider, Fernox recommended its unique


Protector+ Filter Fluid F9, which actively helped the filter to remove significant levels of contaminants from the system, and restored full operation of the boiler, avoiding a costly replacement. The East Belfast Mission supports the community in Belfast through services


such as temporary housing for the homeless. In its Skanios building, two of the critical gas boilers which provide heat and hot water to residents failed in the main plant room, and an urgent solution was needed. The team from the Skanios building contacted a service provider but after the initial repair was unsuccessful, the heating system was temporarily disabled for ten days. As such, East Belfast Mission approached solv to tackle the problem. Despite succeeding in getting one of the boilers operational again, after assessing the second, they found that it was repeatedly failing due to a significant build-up of sludge in the system, due to prolonged inactivity. For further specialist advice, the team contacted Fernox and Richard Thompson, Ireland Country Manager, who attended the site. He recommended installing side filtration and dosing with Protector+ Filter Fluid F9 as an effective


approach that would require minimal disruption for the building occupants. Protector+ Filter Fluid F9 is designed to provide premium protection for mixed-metal heating and cooling


systems and is only to be used alongside a system filter. Its unique combination of a high-performance inhibitor and an active dispersant enables the chemical water treatment to lift and deliver contaminants to the filter for the safe collection of corrosion, debris and scale. Crucially, the problematic second boiler in the Skianos building was able to run during the two-week period that the Fernox treatment was left to sit in the system for. Solv found that when they returned, it had resolved the issue, and the second boiler had been restored to full working order as well. Given the client had believed the second boiler to be beyond repair and required replacement, Protector+ Filter Fluid F9 saved them having to spend potentially tens of thousands of pounds. With its innovative, best-in-class and environmentally friendly formulation, Protector+ Filter Fluid F9


improves the effectiveness of the system filter while ensuring full protection against corrosion and scale formation, which as a result, extends system life and maintains optimum efficiency. “We would recommend Fernox without hesitation as the team provides a level of support and expertise which is hard to match,” commented Stephen Kane, Managing Director of solv. “We have been using Fernox products for around ten years and throughout this time, we have benefitted greatly from their technical support, both from the company as a whole and directly from Richard, and this adds real value to our business. The combination of Fernox products, expertise as well as its pre- and post-treatment testing has played a


huge part of our success on many projects, including this one.” For more information about Protector+ Filter Fluid F9 and other Fernox products and services, visit www. fernox.com. For more information about solv, visit: www.solvgroup.com.


www.fernox.com Gilberts delivers the low-down


eading independent air movement specialist Gilberts is delivering the low-down on how building services can meet the challenge of the changing office landscape. The drivers of reduced energy costs, creating a healthier working environment and flexible office


spaces are combining to see increasing demand for underfloor air distribution (UfAD): up 8% according to market data(1). Gilberts’ uniquely-designed GFS floor swirl diffuser brings new dimensions for designers and users


of the internal space. Its performance characteristics mean GFS can help towards WELL, LEED and BREEAM accreditation. Gilberts’ GFS circulates air from the floor void with no need for direct ducting. As a result it can


be positioned anywhere across the floor plan. And GFS maximises agile offices: all that is needed is repositioning of the diffuser- often just swopping a floor tile- with no need to reconfigure the air circulation paths nor ducting. The patented design enables the choice of horizontal or diagonal (45) swirling omni-directional


or diffused airflow at floor level. Heating and cooling is quickly and effectively delivered where the occupants are. Excess heat generated by the occupants- people and machines- and airborne pollutants are displaced upwards and out, optimising indoor air quality and comfort. Gilberts has incorporated a volume control damper into the diffuser which regulates the quantity of


airflow as required for occupant comfort and doubles as a dirt trap. The diffuser plate removes easily to facilitate cleaning, adjustment or maintenance. Whilst predominantly used for air supply, GFS can, like all Gilberts’ swirl diffusers, also function as the


ventilation extract, further simplifying the design & specification process. Dave Harding, Gilberts Sales & Marketing Director, comments: “The efficiency of UfAD systems-


delivering heating & cooling at low level is established. Our GFS enhances those proven USPs. It gives much greater flexibility over how the occupied space is used, even as that usage changes. It’s a simple consideration to the specification that can have a huge impact on the appeal for owners and tenants.”
