Ace Roto-Mold Tanks
Ace Roto-Mold Tanks are built to last offering polyethylene liquid & water storage tanks in all shapes and sizes up to 12,500 gallons. Ace rotationally molded products exceed industry standards & expectations.
Ace Roto Mold Plastic Tank Categories Include:
WHAT CHEMICALS CAN BE STORED IN ACE TANKS?:
Identify the chemicals to be stored in the tanks. Be certain to obtain a Certificate of Composition, MSDS (Material Safety Data Sheet) or other data from the chemical supplier so that the actual chemical compounds can be identified properly to evaluate the effect of the chemical on polyethylene storage containers. Be sure to check that the tank, fittings and fitting gasket material are compatible with the chemicals to be contained and the anticipated storage temperatures. Review the Chemical Resistance Chart. This will determine if the chemical to be stored is compatible with polyethylene. If this resistance data does not list the chemical you intend to store in the tank, contact the chemical manufacturer for recommendations regarding storage in polyethylene tanks.
WHAT MATERIALS ARE USED TO MAKE ACE TANKS:
Ace Roto-Mold tanks are offered in medium and high density polyethylene. The polyethylene utilized in the manufacture of Ace Roto-Mold tanks depends upon the size of the tank. There are minimal differences in the characteristic between medium and high density polyethylene. High density polyethylene offers a slightly higher density, chemical resistance and impact resistance than medium density polyethylene. Vertical Tanks 3100 gallons and larger, Cone Bottom Tanks 4600 gallons and larger, all Septic and Cistern tanks, all Crop Care Tanks as well as the 2350, 2750 and 3250 gallon Free Standing Leg Tanks are all made standard in high density polyethylene. Please note that all Ace Roto-Mold tanks are available in high density polyethylene if requested.
HOW HEAVY A MATERIAL CAN POLYETHYLENE TANKS HOLD?:
Ace Roto-Mold standard tanks have a specific gravity of 1.7. Our vertical tanks ranging from 20-625 gallons are standard with a specific gravity of 2.0. Specific gravity is the ratio of the chemical weight per gallon divided by the weight of water per gallon (8.33 lb per gallon) As an example, if a chemical weighs 10 lb per gallon, the specific gravity of the chemical is 10.0/8.33 = 1.2 SG. (Metric: kilogram/cubic meter or gram/liter) Substances with a specific gravity greater than 1.0 are heavier than water, those with a specific gravity of less than 1.0 are lighter than water.
WHAT IS THE WALL THICKNESS OF ACE TANKS?:
Wall thickness varies from top to the bottom of the tank. Our tanks 2000 gallons or smaller tend to have an even wall thickness due to the roto-molding process. Ace Roto-Mold standard tanks have a specific gravity of 1.7. We use the right amount of material and resin grades in order to insure that specific gravity is reached. We do provide wall thickness maps for our Vertical tanks 5000 gallons and up as well as our Cone Bottom tanks 4600 gallons and up.
WHAT IS THE WARRANTY ON ACE TANKS?:
Den Hartog Industries’ polyethylene tanks are warranted to be free from defects in materials and workmanship under normal use and service for a period of 24 months on polyethylene Stock Tanks, 60 months on Septic/Cistern tanks and 36 months on all other polyethylene tanks. Warrantor’s responsibility extends solely to repair and replacement of your Den Hartog product and its component parts. Warrantor does not assume responsibility for, nor shall be liable for, any special, incidental or consequential damages.
IS THERE UV PROTECTION IN THE RESIN YOU USE?:
Ace Roto-Mold tanks are molded from polyethylene compounded with the latest technology in ultraviolet (UV) light stabilizers. The UV stabilizers will reduce the harmful effects of ultraviolet light exposure and are intended to extend the life of a tank over similar materials that are not compounded with stabilizers. Our UV rating is “15? on most product materials, which generally means that after 15,000 hours of exposure to the sun, there will be 50% of UV protection remaining. This rating also needs to consider location and prolonged exposure to the sun.
DO YOUR TANKS CONTAIN ANY BPA’S?:
Our tanks are made from polyethylene. Bisphenol A (BPA) is not used as a component in the manufacture of polyethylene. BPA is primarily used in polycarbonate and in epoxies used to line cans. Polyethylene does not leach chemicals and has been used for direct food contact for many years.
ARE ACE TANKS FDA COMPLIANT & ARE THEY SUITABLE FOR WATER STORAGE?
Ace Roto-Mold tanks are manufactured utilizing FDA compliant resins. All Ace Roto-Mold natural colored above ground tanks and below ground cisterns are safe for water storage. Natural, black, blue and green colored tanks are in full compliance with current FDA standards for polyethylene tanks.
WHAT IS THE MAXIMUM TEMPERATURE THAT YOUR TANKS CAN WITHSTAND?
Depending upon the chemicals to be stored, Ace Roto-Mold tanks will handle sustained temperatures of up to 120° F (49° C) and intermittent temperatures of up to 140° F (60° C). Consult the chemical manufacturer or Chemical Resistance Chart for recommendations regarding storage in polyethylene tanks and service temperature limits. Please note that higher service temperatures will lower the specific gravity rating of your tank.
WILL FREEZING TEMPERATURES HURT MY POLY TANK?
Freezing temperatures will not have an effect on a polyethylene tank, however if you plan to keep a liquid in the tank that you know will freeze, be sure to leave sufficient room for expansion. Be aware there is a greater chance of a polyethylene tank cracking during transportation in cold temperatures. Fittings that are exposed to chemicals will have a low temperature rating equivalent to the freezing limit of the chemicals the fitting is exposed to. Note that heaters, heat bands or chemical inhibitors that prevent chemical freeze up will allow the fittings to be exposed to ambient temperatures below the freeze point of the chemical. Again, the low temperature rating of all fittings must be above the point at which the chemicals free or solidify.
