Mixing Tanks & Systems

White Mountain offers two types of mixing tanks, plastic and metal.

Poly mixing tanks include High Density Polyethylene (HDPE), Polypropylene (PP), Polyvinylidene (PVDF) and Teflon (PTFE).

Metal tanks are usually 304 Stainless Steel, 316L Stainless Steel, Hastelloy C and other exotic metals. 

Poly Mix Tanks for Agitation

Polyethylene / Polypropylene / PVDF / PTFE / 316Lss / Hast C – and other materials of construction. FDA + USP VI poly tanks and Industrial/Sanitary/BioPharma metal and stainless mixing vessels.

POLY MIXING TANKS

POLYETHYLENE – PE TANK

FDA Resin White Translucent FDA 21 CFR177.1520 Linear PE tanks offer very good chemical resistance and stress-crack resistance. The operating temperature is from 140 F (60 C) down to -94 F (70 C). HDPE has good impact resistance and can be used for sanitary conditions.

Typical uses: caustics, metal finishing, plating and brine. Strong oxidizing agents, aromatic hydrocarbons and solvents should be avoided. PE we offer is an FDA approved resin.

Fluorinated PE tanks are often used for ultra pure water storage where ozone is used for sterilization. Cross linked PE is not typical for sanitary use so we generally do not offer that.

POLYPROPYLENE – PP MIXTANK

USP VI Resin White
Autoclaveable
Non Cytotoxic, USP VI and FDA 21 CFR177.1520

PP tanks offer very good chemical resistance and excellent stress-crack resistance. Operating temperature is from 220 F (104 C) down to 32 F (0 C). PP tanks feature fair impact resistance and can be used for sanitary applications. PP mixing tanks are good for many organic chemicals and etching chemicals. Strong oxidizing agents and aromatic or chlorinated hydrocarbons should be avoided.

KYNAR – PVDF PROCESS VESSEL

Polyvinylidene Tank
USP VI Resin
Great corrosion resistance and high temp, very high purity
Non Cytotoxic, USP VI and FDA 21 CFR177.1520

PVDF tanks offer superior resistance to inorganic acids, strong oxidizing agents and halogenated compounds. PVDF tanks also offer excellent resistance to stress-crack but only fair resistance to impacts. It has a temperature operating range of 230 F (110 C) down to -40 F (-40 C)

TEFLON – PTFE BLENDING VESSEL

PTFE tanks offer superior chemical and corrosion resistance. PTFE also has a wide range of temperatures from 260 C down to -270 C. PTFE is an excellent material for sanitary applications as it is inert but also is more costly. PTFE is not as strong as other plastics but can be obtained with fillers to increase its physical strength.

Mixer shaft/impeller are available with USP VI Teflon and ETFE coating.

Stainless/Metal Mixing Tanks

304SS – STAINLESS STEEL TANK AND MIXER

304 Stainless Steel is perfect for pharmaceutical and chemical industries due to high corrosion resistance. 304 SS tanks can be used at wide temperature ranges and have high physical strength.

316LSS – STAINLESS STEEL VESSEL AND AGITATOR

316L SS alloy has a higher corrosion resistance than 304 SS and has a higher operating temperature range. This material is resistant to strong acids – preferred for more aggressive applications such as digesters, tanks and evaporators.

HASTELLOY – GRADE B AND C AGITATED TANK

Hastelloy C is a nickel-chromium-molybdenum-tungsten alloy with superior corrosion resistance and is highly resistant to pitting and cracking. Hastelloy C can be used in a wide variety of applications including corrosive chemicals at elevated temperatures, flue gas scrubbers and nuclear fuel reprocessing. This alloy has a high cost for construction and polishing.
