FAQ'S FOR BOILERS
Q Where does the ScaleAway Unit get installed?
A Usually in the "make up" line for both open and closed loop systems. Depending upon the physical structure, the unit might also be installed in the recirculating condensate line.
Q What additional hardware is necessary for installation?
A Typical installations are directly in-line and might require some standard plumbing fittings. This would hold true for steam, fire tube, open or closed boiler systems.
Q How do you size a ScaleAway Boiler Filter?
A The size is based upon the put-through flow rate. In other words, how many GPM the boiler filter will have to handle.
Q At what point will the scale be removed?
A The scale will begin to loosen and turn into a "soft scale" within 24 hours. Over the next 30-45 days scale will slough off and come through in the water stream. To prevent clogging it will need to be filtered out by a sediment/particulate filter prior to the ScaleAway.
Q Are there any tests
that should be taken?
A To determine if the filter is still working properly tests could be taken for zinc, copper and pH. After the installation test for these substances often during the first two weeks to establish a "baseline" and once a month thereafter.
Q How will we know
when the disks need to be replaced?
A You will notice a significant drop in the zinc and copper levels along with a drop in the pH. If the levels continue to drop, replacement time is near.
Q How often do the media packs need to be replaced?
A On average, once a year. Replacement time will vary.
Q Can we stop using
chemicals?
A Yes. No scale or biological control chemicals are needed.
Q What changes can we expect to see?
A Typically, pH will increase. Copper and zinc levels will also increase. Water can run at higher TDS before blowdown is necessary. Units will run at greater efficiency.
Q Is it a problem if
we don't use the equipment all year ?
No, just make sure not to drain the water from the filter. Once exposed to water, if it then becomes exposed to air, the material will deteriorate more rapidly than normal.
Q If we shut the system
down can algae and bacteria grow ?
A If there is no water in the equipment algae and bacteria will not grow. The filtration material inside the filter is bacteriostatic, so no bacteria or algae can grow inside the filter.
Q If the filter is installed outside does it need to be protected from the elements?
A As water will be flowing through it, it cannot be allowed to freeze.
Q How do we determine
the system is running efficiently?
A You can test for the difference in thermal efficiency between the incoming and outgoing water. But a visual inspection after 30 days and every 30 days thereafter is best.
Q How do your systems
compare with chemical treatment?
A In general our systems are less expensive, require no EPA regulations, are not considered hazardous waste and are recyclable.
Q How are your systems less than chemicals?
A. The main savings are: the reduction of fuel which means your systems will operate at greater efficiency, less blowdown which means your cost for utilities will be greatly reduced, minimal or no downtime which means reduction in labor costs and elimination of acid wash, no hazardous materials to deal with which means reduction in accidents and lowering of workman's comp costs as well as less injuries and missed time, and many other day to day operational factors. When all things are considered and the total operational costs are taken into account, our systems cost much less than chemicals.
Q Are the systems
corrosive?
A. No. Zinc is a known anti-corrosive and is the most common element used for metal plating to protect against corrosion.
Q Are these magnets?
A. NO and most definitely NO, NO !!
