Cooling Tower Solid Chemical Water Treatment

Safer Chemical Handling. A Sustainable Solution. Easy Chemical Storage.

A Safer Alternative to Liquid Chemical that Actually Works for Cooling Tower Efficiency. 

We get it, there are a lot of chemical companies that say they are going to save money, time etc. etc. but often they don't deliver on the promised results.

Our business is to help you decrease water use and chemical use, and minimize energy costs. We pay close attention to the goals you have set (or developed or put into place) for your building and will aim to achieve what matters most to you:  keeping your people safe and systems running efficiently.

By Switching to Solid Chemistry you Will:

  • Keep Your Team Safe: No more handling 55 gallon drums or splashing and spilling of highly acidic or alkaline chemicals
  • Save on Freight Costs: Liquids can cost almost four-times the amount of
    to ship
  • LEED Potential: CO2 reduction is a direct result of switching to solid chemistry.
  • Less Frequent Delivery/Less Refills Required: Solid Chemistry discs are stacked in the dissolver (up to 4 per dissolver) and allows for complete product use.


The packaging for RMC Solid products is fully recyclable. This includes the HDPE for the bottles, the fiberboard packaging for the product, the paper for the labels, and the wrapping for the discs.

Yes, RMC recommends that all chemical feed equipment be installed within a weatherproof enclosure. Your RMC representative will provide information regarding a suitable enclosure.

Whether the equipment is panel-mounted in advance or installed loose in the field, the equipment essentially has 3 tie points for water/solution and 3 anchor points for the mounting bracket. All water/solution connections are easy to tie to, with tubing compression fittings for the inlet water and chemical solution outlet and hose barb for the overflow port. Once the units are installed, start-up and commissioning take minutes.

The Ultra-M dissolve units were designed for increased reliability, quality and durability so our solid chemistry can be dissolved with confidence given any situation. The Ultra-M was built with the advantage of a non-electric mechanical level system and integrated flow control providing accurate chemical dosing for a variety of water treatment systems. All materials of construction are chemically compatible to the solid products in use.

The products are designed to dissolve readily and rapidly to generate safe solutions. Water and ambient temperatures have a small impact on dissolution; these temperatures are often very consistent over shorter periods of time, making it easy to adjust feed rates as necessary. Most products can be field tested for solution strength, allowing for dialing in pump and feed settings during start-up and normal operation.

Yes, CO2 reduction is a direct result of switching to solid chemistry. Assuming a 2,000-ton average load at 5 cycles of concentration, switching from liquids to solids reduce CO2 emissions by 56 tons annually. This can help achieve LEED credits.

4 gallons of RMC Solid Treatment Chemicals are equivalent to a 55-gallon drum of liquid chemical treatment. Use what is needed, when itis needed, with no chance of liquid spill or component separation. No mixing equipment needed.

Yes! Solid chemistry requires best in class raw materials to make high quality products. In fact, solid chemistry can be more effective than liquids in some cases because of the mix of scale and corrosion inhibitors along with the polymeric technology incorporated into the formulation.

With over 20 years of application experience and a continual evolution of product and equipment technology, Solid Chemistry is proven to be a very effective and sustainable solution for cooling tower, boiler, and closed loop applications. With any technology, it takes professional water treaters to properly select, size, and implement solutions; RMC’s water and energy team is ready to..

Solid products have been used since the early days of water treatment, whether it be potatoes, tannins, etc. The Solid Chemistry form used by RMC has been in use for over 25 years.

RMC has had Solid Chemistry in their line for at least 10 years, with longer experience if you include folks who have used products prior to RMC’s incorporation of the technology.

Yes, RMC Cooling water products for scale and corrosion control utilize trace chemistry for ease of testing and control. RMC is also market leader in boiler water treatment technology using solid products to treat boilers operating above 150 PSI.

Solid product chemistry has been effectively used to treat cooling water systems in excess of 1000 tons. The development of the program which includes the applicable products and equipment will be provided by your RMC Technical Representative.

I find the dry chemical is a lot better for storage vs liquid drums. Safer to change when depleted.

Raymond LaPierre, Lead Maintenance Operator, Cacique

Dry or solid chemicals have shown us that they are more versatile and easy to handle, economical and safer. We've fixed issues with chemical spills and lowered the cost of transportation and with application closer to the systems. Liquid chemicals are heavier by their presentations, with all of us having to take many precautions but even more with liquids, with possible more chemical spills and higher costs in transportation and applications away from the system at high operating cost.
