Case Study
Overview
This 151 bedroom hotel is in a hard water area and historically had not implemented any solution to resolve the resulting problems. As a consequence, the water systems were badly scaled up, which was impacting on the operation and running costs of essential pieces of equipment.
Key Issues
During a site survey and initial inspection, the following areas of concern were raised by the Maintenance Manager:
- Dishwashers and ice machine were badly scaled
- Rational steam ovens were badly scaled and required callouts for a full descale every month
- Potential for increased waterborne bacteria, especially Legionella, due to scale build-up throughout the system
- General Housekeeping issues due to scale such as showerheads, taps and other water fittings which were regularly scaled up
- Waste downpipes on the outside of the building were choked with limescale
Our Solution
In December 2020, after the site survey and discussion with the maintenance manager, an IntegroTM 4 was installed on the mains water supply covering the cold-water tank system.
In addition, and for extra protection to the hot water system, an IntegroTM 2 v3 was installed directly before the calorifier.
Environmental Benefits
In addition to the quantifiable savings on energy consumption, labour/call-out charges, equipment downtime, cleaning and Legionella control, the hotel are enjoying the following additional benefits:
- Reduction in scale and corrosion to critical equipment, meaning decreased engineer visits and reduction in spare parts which would otherwise carry direct and indirect increases in the hotel's carbon footprint
- Reduced chemical use
- Extended life of all water related equipment and improved efficiency
- Improved water quality and efficiency of hot water equipment
Summary
Since installation in December 2020, the IntegroTM technology has been reported to have been working really well throughout the hotel to eliminate existing scale and prevent any further build-up and the hotel are continuing to use the system to great effect.
What the customer had to say?
“I haven’t had Rational out to descale the steam ovens since we re-opened, we used to have to call them every month to do a full descale so the system is working really well. The dishwashers are also all keeping free from scale. I have noticed a difference in the limescale build-up, it’s virtually non-existent since installing the technology. They have caused a few leaks though, where the limescale has been eaten away round joins and valves, but that was to be expected and is a good thing because it identified issues we would never have seen and enabled us to repair them before they caused too much damage.”
