If your facility demands cleanable, low‑retentive air handling—think food & beverage production, healthcare, pharmaceutical suites, micro‑electronics or validated cleanrooms—Sinteco’s Hygiene® line is purpose‑built. And if you’re in Kentucky or Southern Indiana, you can source and support these systems through Thermal Equipment Sales.
What makes a Sinteco “hygienic” AHU?
Sinteco’s hygienic construction emphasizes materials, geometry, and washability to minimize residue and speed turnarounds:
Welded stainless‑steel interiors (up to TIG‑welded 1.5 mm skins) with sprayed polyurethane insulation (70–150 mm) on higher‑hygiene tiers—built for frequent, even aggressive, wash‑downs.
Rounded inner corners, sloped bottoms and drain pans to evacuate condensate and wash water—reducing stagnant zones where biofilm can form.
Plug‑fan architecture and monolithic panel systems (polyester/PU or stainless depending on tier) to improve cleanability and limit thermal bridges.
Internal lighting and safety interlocks (options) that simplify inspection and safe maintenance during sanitation.
Sinteco publishes clear hygiene tiers (★ to ★★★★) indicating panel materials, washability, and stainless‑steel content—making spec alignment straightforward.
Options & configurations that fit your process
Energy recovery, free cooling, humidifier and exhaust variants are native options in the Hygiene® range, streamlining single‑vendor design.
SIMUN: for ultra‑dry rooms, the Hygiene® SIMUN integrates a desiccant wheel and controls to drive absolute humidity as low as 0.1–0.2 g/kg—ideal for chocolate, coating, lyophilization support spaces, and low‑dewpoint packaging.
Where Sinteco excels
Food processing (wash‑down zones, maturing rooms, packing)
Healthcare & pharma (ISO‑class clean areas, validated rooms)
Micro‑electronics (particle‑controlled environments)
Sinteco’s own cleanroom and air‑treatment documentation underscores these application fits and the use of high‑efficiency (H13/H14) filtration in associated plenums/air cleaners where required.
Performance & sanitation advantages you can operationalize
Low bacterial retentiveness via smooth surfaces and minimized joints; no/low thermal bridges reduce condensate risk.
Frequent foam‑based wash‑downs on higher hygiene tiers (★★★/★★★★) without degrading the casing.
Monolithic panels & welded frames promote tightness and durability versus jointed, aluminum‑post casings common in basic AHUs.
If your URS references EN 1886 / EN 13053 casing & component performance, those standards define leakage, mechanical class, and component ratings industry‑wide—useful when benchmarking any AHU.
Sizing the hygiene tier: a quick map
AHU ★ — Polyester/PU + galvanized steel; limited washability (dry clean).
AHU ★★ / ★★+ — Polyester/PU with stainless supports and sloped bottoms (★★+ adds SS bottom); occasional to frequent washing.
AHU ★★★ / ★★★★ — TIG‑welded stainless‑steel skins (inner, and outer on ★★★★) with sprayed PU insulation; strong & frequent washing.

Spec snapshot (for quick comparisons)
Materials: up to TIG‑welded SS (1.5 mm) casings; sprayed PU insulation 70–150 mm (higher tiers).
Hygiene geometry: rounded corners, sloped bottoms/pans, tight casings to minimize condensate and debris traps.
Functional options: energy recovery, free cooling, humidification, SIMUN desiccant for ultra‑dry rooms.
Filtration ecosystem: support for high‑efficiency filters (H13/H14) in connected plenums/cleanroom solutions.
FAQs
Q1) Are Sinteco hygienic AHUs truly wash‑down capable?
Yes—models in the ★★★/★★★★ tiers feature TIG‑welded stainless interiors, rounded corners, and sloped bottoms, built for strong and frequent washing.
Q2) Can I achieve very low humidity for sensitive processes?
Yes—the Hygiene® SIMUN variant adds a desiccant wheel, with published capability down to 0.1–0.2 g/kg absolute humidity (application‑dependent).
Q3) Which industries commonly specify Sinteco hygienic units?
Food & beverage, healthcare, pharma, and micro‑electronics—including use within validated cleanrooms and processing rooms.
Q4) What filtration classes are supported?
Project‑specific, but Sinteco’s cleanroom and air‑cleaner documentation reference H13/H14 stages where needed in the overall system design.
Q5) Do these units align with industry standards like EN 1886 / EN 13053?Those standards define casing and component performance used by many specifiers. Confirm target classes during selection/submittal based on your URS.
Q6) Who sells and supports Sinteco hygienic AHUs locally?
Thermal Equipment Sales covers Kentucky & Southern Indiana and can assist with selections, submittals, and startup coordination.
