20% DBNPA

What is DBNPA?
DBNPA formula is 2,2-Dibromo-3-Nitriloproprionamide.

When is DBNPA used?
It is used in recirculating cooling water systems and closed loop systems to control microbial growth. Its advantages are it is effective over a wide pH range against the microorganisms typically found in these systems. It is good for killing aerobic bacteria, fair for anaerobic bacteria and fungi, and poor for algae.

What is the feed rate of DBNPA?
12 to 48 ppm is for maintenance dosage. 480 max slug dosage. Use to monitor performance. This product is 20% in concentration.

For new cooling tower startups, consider our ChemWorld 101 Cooling Startup Kit. This kit includes the following:

One 5 gallon pail of ChemWorld Q-ALK-PC - This product is required to clean the debris and greases prior to startup.
One 5 gallon pail of ChemWorld 1334 - ChemWorld 1334 is scale and corrosion control cooling tower chemical. After startup, you can perform testing of your water hardness and alkalinity and we can tune in your exact chemical for long term protection.
One 5 gallon pail of ChemWorld 56 - ChemWorld 56 is a 12.5% sodium hypochlorite product that is required to kill bacteria. This is the cheapest easiest product to get your system up and going, you can convert to tablets or a stablized bromide product after startup.
One LakeWood 140 Cooling Tower Controller - You will need to set the controller to feed and bleed the cooling tower water to maximize cycles and to minimize chemical usage rates. An optional dual biocide water treatment can be implemented after startup. This is model 1239597 (which is board mounted unit that has the flow assembly on the left).
One 1167435 Cooling Tower Blowdown Valve (1" NPT) - This will be required when the cooling tower calls to release cooling tower water.
Two Stenner 45MHP10 Adjustable Head Pumps - One pump is required for the corrosion/ scale prevention chemical and for the biocide. Each pump is rated to 100 psi, which should be enough to feed the chemical into the system. The ideal spot to feed the chemical is into the return header of the cooling tower. These Stenner Pump kits come with chemical injection valves that will allow for quick injection of each chemical into the side stream water loop that is used to monitor the cooling tower conductivity.
One complete CWTK-200 Cooling Water Treatment Test Kit. This kit is contains every test you will need to set up and fine tune your water treatment program.
One Chemical Metal Test Station Cabinet - You need to keep your test kits and lo sheets in one clean location. This test kit is ideal for cooling towers. Items in the photo of the test kit not included.
