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[cite: 1]. 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[cite: 1]. Certified to **IP69K water tightness standards**, these units withstand high-pressure, high-temperature chemical jet washdowns (up to 100 bar at 80°C)[cite: 1]. 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[cite: 1]. 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)[cite: 1]. WE DRIVE HONGKONG LIMITED provides technical sourcing, ratio verification, and custom PCS motor adapter matching for Neugart HLA hygienic planetary drives worldwide[cite: 1].

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[cite: 1]:
| 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[cite: 1]. 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[cite: 1].
