Chemical Filling Machine

Our chemical filling machines handle: industrial acids (hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid), alkalis (sodium hydroxide, potassium hydroxide, ammonia solution), organic solvents (acetone, MEK, toluene, xylene, isopropanol, ethanol), petrochemicals (mineral spirits, kerosene, naphtha), specialty chemicals (adhesives, resins, silicones, lubricants, surfactants), and agrochemicals. Wetted part material selection is chemical-specific — we require a completed Chemical Compatibility Form before final specification to support correct material selection.

Our chemical filling machines are available in: Zone 2 (Ex ec IIC T4 Gc) — for locations where explosive atmospheres occur occasionally during normal operation. Required for most solvent-filling environments. Zone 1 (Ex d IIB T4 Gb) — for locations where explosive atmospheres are present continuously or frequently. Required for filling highly flammable liquids (flash point <23°C) and Class IA flammable liquids. Zone 0 — for use inside vessels and containers where explosive atmospheres are present continuously. Zone 0 is addressed through process design rather than equipment documentation in most filling applications. The correct zone classification is determined by the product flash point, vapor pressure and the filling room ventilation — we can assist with zone classification if needed.

We require completion of our Chemical Compatibility Form (available on request) which specifies: chemical name and CAS number, concentration, temperature at filling, pressure, and any known incompatibilities. Our engineering team then confirms wetted material selection against a comprehensive chemical resistance database. For novel or unusual chemicals, we recommend a material immersion test (30-day soak test) using coupons of the specified wetted materials. We provide the test coupons and a standard test protocol at no charge for qualified projects.

The drum filling machine is optimized for large containers (50L–200L drums) with emphasis on net-weight accuracy (by RFQ) and high throughput (up to 120 drums/hour). The chemical filling machine covers a wider container range (1L–200L) with emphasis on chemical compatibility (broader material options) and regulatory compliance (GHS batch records, ATEX full system). For 200L drum filling of aggressive chemicals (acids, alkalis), the chemical filling machine with drum-size configuration is the appropriate choice. For high-volume drum filling of less aggressive chemicals (lubricants, water treatment chemicals), the drum filling machine is more cost-effective.
