Neugart HLA Hygienic Design Stainless Steel Planetary Gearboxes
The Neugart HLA Hygienic Design Planetary Gearbox Series (featured model: HLA070 1-Stage 5:1 Ratio) is the world's first **EHEDG-certified hygienic design planetary gearhead**, engineered specifically for food processing, primary packaging, pharmaceutical dosing, and chemical washdown environments. Built with high-grade electropolished stainless steel casings featuring smooth, rounded contours, the HLA series eliminates horizontal flat surfaces, blind pockets, and exposed bolt threads where organic residue or bacteria can accumulate. Certified to **IP69K water tightness standards**, these units withstand high-pressure, high-temperature chemical jet washdowns (up to 100 bar at 80°C). Pre-filled with **NSF H1 food-grade synthetic grease**, HLA reducers utilize specialized radial shaft seals with PTFE sealing lips to prevent lubricant leakage into food zones. Incorporating precision ground helical gearing, HLA gearboxes deliver exceptional positioning accuracy (<3 to <5 arcmin backlash) and high dynamic efficiency across 3 frame sizes (HLA070, HLA090, HLA115). WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio verification, and custom PCS motor adapter matching for Neugart HLA hygienic planetary drives worldwide.

Standard Washdown Gearbox to Neugart HLA Hygienic Upgrade Guide
Direct replacement guide for upgrading conventional painted or epoxy-coated washdown gearboxes to EHEDG certified Neugart HLA stainless steel planetary units:
| Conventional Washdown Reducer | Hygienic Risk / Failure Mode | Current Neugart HLA Equivalent | Key Performance & EHEDG Advantages |
|---|---|---|---|
| Epoxy Painted / Anodized Servo Reducer | Paint flaking under 100 bar high-pressure cleaning contaminates food line | Neugart HLA070 Stainless Reducer 100% Electropolished | Solid high-grade stainless steel casing will never chip, flake, or corrode under caustic washdown. |
| Square Aluminium Washdown Gearbox | Horizontal flat surfaces and sharp corners trap washdown water and bacteria | Neugart HLA090 Hygienic Reducer EHEDG Self-Draining | Curved, self-draining outer contours eliminate standing liquid and bacterial growth pockets. |
| Standard IP65 Sealed Planetary Reducer | Chemical cleaning agents degrade rubber seals, leading to oil leakage into product | Neugart HLA115 IP69K Reducer IP69K + NSF H1 Grease | Dual PTFE radial shaft seals + NSF H1 food-grade synthetic grease guarantee 100% safety. |
Expert Technical Sourcing & Washdown Motion Control Notes
When retrofitting washdown processing equipment or upgrading to strict EHEDG/FDA sanitary guidelines, switching to Neugart HLA series planetary gearboxes delivers immediate performance benefits: zero paint flaking risks via electropolished stainless steel construction, IP69K high-pressure water tightness, self-draining curved surfaces, ultra-low torsional backlash (<3 arcmin), and total peace of mind in splash and contact food zones. Simply provide us with your existing reducer designation or servo motor part number, and our technical engineering team will deliver a 100% compliant replacement specification and proposal.
