In this issue of Healthcare Matters, we are pleased to feature Meltones Ltd as our Water Treatment Company of the Month.
Meltones Limited, founded in 1989 by Anthony and Carmelita Fernandez as Mach Engineering, started in the marine industry specialising in ship spares and ventilation systems. They expanded into energy-efficient lighting through Mach Electronics and later diversified into renewable energy and HVAC water treatment, partnering with the Great Little Water Company (GLWC) using non-toxic solutions. Their main focus on clean water treatment in HVAC systems is crucial for ensuring efficient and reliable heating and cooling, especially in medical facilities.
Tony added, “A non-toxic formula is used to address major issues such as scaling, fouling, corrosion, and biological growth (bacteria) within these systems. This preventive approach helps to maintain system efficiency and longevity. Additionally, we offer emergency cleaning services to clear and restore fouled heating and cooling coils. Along with these treatments, our specialised consultancy services are offered for HVAC water management, including critical analysis of steam boiler water reports and tailored recommendations to ensure optimal system performance.”
Tubes and tube plates in LTHW boilers can develop cracks over time because of overheating due to scale and sludge. Tony described a time when GLWC’s services were called upon for a significant project.
“We were contracted by a hospital in Berkshire to clean the heating system by removing scale and sludge, and after just one more overheating issue, the boilers began functioning well with no further breakdowns. Although the boilers were only five years old, further inspection revealed that improper modifications during a previous inspection created potential stress points, leading to failures. We recommended rounding the edges of the cut plates and re-welding to prevent future issues and premature failures however, due to repeated failures, the Trust decided to replace the boilers. Our recommendations helped them secure a settlement from the construction company for new boilers. We also suggested installing a water softener and conducted ongoing maintenance, which resulted in exceptionally clean boiler tubes after six years. This highlighted the effectiveness of our CT-01 treatment and our commitment to ensuring systems meet manufacturer specifications.”
CT-01 and CT-02 are non-toxic, food-grade solutions that don’t require COSHH training. It’s a green solution, that helps to maintain healthy water chemistry by breaking down scale and sludge without environmental risks. Additionally, CT-01 improves thermal efficiency by removing hard scale, reducing energy use and CO2 emissions, and it can also soften water by removing calcium ions, preventing further scale buildup.
The NHS is one of GLWC’s main customers. GLWC is well versed in treating closed loops, and these present no real threats directly to patients unless leaks from the system reach patient areas, “We want NHS sites to accept us as the GLWC The HVAC Closed Loop Doctors. We have treated an existing CHW loop in Oxford NHS and an NHS site in Tooting, where we successfully cleaned the chilled water loops and presented this for successful commissioning and warranty of the equipment and system offered to the client,” said Tony.
Soon, GLWC will be introducing its Ultra Filtration Equipment that will be much more affordable in comparison to both softeners and expensive RO units.
“We have observed that recently installed Domestic Hot Water Plate Heat Exchangers (PHEs) are running with hard water, leading to hard scale build-up. This reduces heat transfer and outlet temperatures, which, in hospitals with long water runs, can create conditions favourable for legionella growth and also system breakdowns.”
