Chemical Feeders
Reliable, lightweight feeders are provided for systems lacking appropriate feed equipment. These feeders require no relief valves, gauges, timers, pumps, meters or electricity, and are nearly fail-proof.

Pressure FeederPortable Pressure Feeder: Hydronic Loops
Replaces traditional pot/shot/by-pass feeders.
Employs ambient air and pressure generated by a
hand-pump to feed treatment via any system faucet.

Dedicated Eductor Feeder: Steam Loops
Replaces traditional metering pumps.
Employs an adjustable eductor to draw measured Diffusion Feeder
amounts of treatment into the feedwater.

Disposable Diffusion Feeder: Cooling Towers
Replaces traditional self-contained feed systems.
Employs a fine-mesh bag which allows treatment
to slowly dissolve and diffuse into the water reservoir.


Laboratory Report

Samples are analyzed the day they arrive, and results are recorded in a clean, color-coded layout. Reports are emailed to you and posted online in your client area, available for viewing any time. Click here for the report.


Preventive Treatment

Preventive TreatmentEach treatment chemical is packaged, pure and undiluted,
in a small bottle as a unit dose, which is the quantity needed
to correct the chemistry of 1000 gallons of water. When treatment is required, the report indicates the number of
unit doses to be added to the system.

Chemicals are:

  • Approved system additives, with well-known protective mechanisms.
  • Fed using any commercial chemical feeder or ones we supply.
  • Chemically-compatible with one another.
  • Effective at very low concentrations.
  • Biodegradable and easy-to-handle.
  • Safe to hold in general storage.

Sampling Kit

Sampling KitThe kit will arrive at your door when it is time to sample. Everything you need to obtain a sample and mail it to our
lab is provided. Includes color-coded, customized labels,
clear instructions, and postage-paid return mailer.


Stop-Leak

Kevlar PulpKevlar P
ulp has the perfect fiber size and geometry to flow through hydronic loop pumps and pipes. Supplied at the proper dose, it quickly plugs holes smaller than 3/8", but
does not interfere with valves or larger system apertures.


System Monitor
System Monitor
A system monitor consists of a filament of mild steel,
wrapped with a fine copper wire, and embedded in the
threads of a small nylon bolt. When in place on a system faucet, the system monitor experiences corrosion, scaling
and fouling at the same rate as the system. It provides direct, visual documentation of interior conditions. After a year of exposure, the system monitor is returned to the laboratory where it is graded, photographed and archived. The photograph is posted online in your client area, available for viewing any time.
