Drawer-In-Housings (DIH)
High-efficiency gravity magnets for dry products. Alternating rows of magnetic tubes force a zig-zag cascade through the field for maximum capture with low re-entrainment.
- Available with 1″ (Standard), 2″ (Mid-Tube), and 3″ (Large-Tube) magnetic tubes
- Cleaning methods: SimpleClean™ (manual), EZ-Clean, Self-Clean, and Continuous-Clean
- Square or round housings, sanitary finishes, custom transitions, multi-drawer configurations
Choose Your Cleaning Method
SimpleClean™ (Manual)
Economical for low tramp loads. Non-magnetic wipe-off zone lets you clean tubes quickly outside the flow.
EZ-Clean
Slide-out handles; wiper seals strip metal to a catch pan for fast, repeatable cleanouts.
Self-Clean
Pneumatic actuation opens the drawer and discharges captured tramp automatically—great for remote installs.
Continuous-Clean
Cleans while product flows. Sealed discharge isolates fines and dust for high-uptime operations.
Standard Tube DIH — 1″ Tubes
Classic multi-row drawer housing using 1″ tubes on 2″ centers for broad application coverage and high purity. Offered in SimpleClean™, EZ-Clean, Self-Clean, and Continuous-Clean models; food/sanitary builds available.

Full DIH spec table (all sizes, clearances & flow by bulk density) available on request.
Mid-Tube DIH — 2″ Tubes (MTH)
For difficult-flowing products at higher rates. 2″ tubes on 4″ centers reduce bridging while maintaining rare-earth intensity. Available in EZ-Clean and Self-Clean; Continuous-Clean by application.
Standard Sizes (sample)
| Model | Opening (L×W) | B (in) | C (in) | D (in) | Tubes | Rows |
|---|---|---|---|---|---|---|
| MTH 12×12 | 12×12 | 22 | 27.75 | 9 | 3 | 2 |
| MTH 14×14 | 14×14 | 24 | 29.75 | 9 | 3 | 2 |
| MTH 16×16 | 16×16 | 26 | 31.75 | 9 | 4 | 2 |
| MTH 18×18 | 18×18 | 28 | 33.75 | 9 | 4 | 2 |
Additional sizes and optional transitions available.
Large-Tube DIH — 3″ Tubes (LTH)
For powders with severe bridging (e.g., flour, powdered sugar). 3″ tubes on 6″ centers sit below steep diverters to keep flow moving while maintaining rare-earth capture. EZ-Clean and Self-Clean available.


Standard Sizes (sample)
| Model | Opening (L×W) | B (in) | C (in) | D (in) | Tubes | Weight (EZ/SC) |
|---|---|---|---|---|---|---|
| LTH 12×12 | 12×12 | 22 | 24 | 10 | 2 | 140 / 225 lb |
| LTH 14×14 | 14×14 | 24 | 26 | 10 | 2 | 160 / 235 lb |
| LTH 16×16 | 16×16 | 26 | 28 | 10 | 2 | 200 / 255 lb |
| LTH 18×18 | 18×18 | 28 | 30 | 10 | 3 | 220 / 280 lb |
Ask about sanitary finishes, metal-detectable seals, and high-wear options.
Body Shapes, Transitions & Finishes
- Square or round housings (round often used in sanitary/plastics installs)
- Custom transitions (flanges/adapters), custom tube spacing, multi-drawer arrangements
- Food/Sanitary builds, metal-detectable/X-ray inspectable seals, Hydex® wipers, and optional wear-resistant coatings
Special Applications

RotoDrawer™
Rotating tube bundle keeps cohesive or oily powders moving while maintaining capture—useful where fixed tubes can bridge or smear.

OX® Drawer-In-Housing
Heavy-duty DIH for sticky/abrasive media. Specialty wipers and wear-resistant options reduce sticking, galling, and buildup; available EZ or Self-Clean.
Why Industrial Magnetics (IMI)?
IMI combines food-safety certifications, measurable magnet performance, and U.S. manufacturing with real application engineering. The result is separation equipment that’s easier to specify, validate, and audit—without sacrificing flow.
Food-Safety Certifications
- HACCP International certified sanitary Drawer-In-Housings (Food Zone)
- USDA AMS accepted dairy, meat & poultry versions
Measurable, Auditable Performance
IMI’s Opti® rare-earth circuits are designed around FSMA/HACCP/GFSI audit criteria with minimum, repeatable thresholds (gauss & pull) and documentation.
About Opti® circuitsStrength Where It Matters
- UHI-52™ rare-earth captures fine metal & work-hardened stainless
- Opti-L large-tube circuits exceed 12,000 gauss and Opti-T handles up to 356°F
