Every dimension in this book is issued per project on the dimension
sheet. We do not print figures we have not measured on the assembly that ships.

SUDITEK / INDUSTRIAL01 - The line
01 - Position
Two floors that get inspected.
Suditek Purity builds stainless drainage for the commercial kitchen and the food production
hall: the two floors where somebody arrives with a swab, a clipboard or a hose.
The kitchen
Bursty flow, solids arriving with one bucket, a nightly washdown by whoever is on the closing shift. The
floor is walked on, wheeled over, and sometimes seen by a customer.
Discreet slot runs where the floor is visible
A basket at the low point
A cleanout at the end of the run
The production hall
Continuous washdown, product on the grating, pallet trucks, cleaning chemistry, and an audit that asks for
the cleaning procedure rather than the brochure.
Made-to-measure trench under the line
One outlet per run, not one per hall
Access where the line can be rodded
A drain is not hygienic because the steel is 316. It is hygienic because somebody decided, before
the first cut, what would make it cleanable.
What we do not claim: food-contact certification we do not hold, flow or
load figures we have not measured, and anything outside the drainage layer.
03
SUDITEK / INDUSTRIAL02 - Six rules
02 - Rules
Six rules, and nothing in the range gets past them.
Borrowed from the way a food plant audits equipment, not from the way drains are sold. A fitting
that fails one of these does not go in the range.
01
No crevice to hide in
Internal corners radiused, welds dressed flat, no overlap where two sheets meet. The body is one continuous surface from flange to outlet.
Finger test on the first article: along the inside corner, then over every weld. If it catches, the part is reworked, not re-described.
Basket and grating seats are pressed, not welded on - a welded seat leaves a step.
No folded lip inside the water path. Folds trap film; film is where the count comes from.
02
Out by hand, in one move
Basket, slot insert, grating and seal lift without a key, a hook or a procedure. One hand, one movement, with a glove on.
Timed on the first article: out, and back in, in under a minute by one person.
No fastener in the removal path. If a screw has to come out, it will not come out at 2 a.m.
Seals and inserts drop back into one position only - no refitting upside down.
03
Fall does the work
The body is set so the last metre still drains. Water that has to be pushed is water that sits, and a puddle is a documented non-conformance on an audit.
Outlet end checked on a level floor: no standing water beyond the invert after a full flush.
Falls coordinated with the slab before the body is set - the body cannot fix a flat floor.
Long runs get an outlet at both ends where the fall allows it; asked at quotation, not after.
04
Seal or separation - never neither
Every outlet in the range is either sealed or separated: a 50 mm water seal against sewer gas, or a separator against fat reaching the discharge. Measured in place, with the basket fitted.
Seal depth measured at the worst point of the seal, not the nominal one.
Rooms that go days between washes get a different cartridge - declared before we quote.
No anti-odour claim that is not a water seal or a dry trap. There is no third method.
05
Bonded, not butted
The flange turns into the waterproofing and the body is anchored to the slab. The steel-to-floor joint is a detail, not a bead of sealant applied on site.
Flange geometry issued with the section drawing so the membrane detail can be drawn first.
Anchors specified per slab type - a fixing that pulls out leaves a gap you cannot see.
No reliance on a site-applied fillet as the only seal. It is a second line, never the first.
06
Documented, not described
Dimension sheet, section, material certificate, cleaning procedure. Issued with the order, per project, per market.
Every claim on this site maps to one of the four documents - nothing is left as an adjective.
Heat number on the certificate matches the batch on the part.
Cleaning procedure written for the person holding the hose, not for the file.
Each rule is checked on the first article of a family and recorded: finger
test, timed removal, flush test, measured seal depth, flange drawing, document set.
04
SUDITEK / INDUSTRIAL03 - Two families, two modules
03 - Range
Two channel families. Two modules that fit both.
The families split by the floor they serve. The modules are what turn a channel into a working
run: solids stop in a basket, and the line stays reachable.

SUDITEK / INDUSTRIALSS400X - KitchenSlot 400
08 - Series / SS400X
KitchenSlot 400 Series
A continuous slot along the wall or the run, flush with the finish, body below and seal under it. The kitchen gets a line on the floor instead of a hole in it - and the trolley wheel that rolls over it does not drop in.

Access
rodding eye at each end
A slot is a promise about what will never go down it. Break the promise once and the run is opened with a rod forever.
How it fails
A slot narrow enough to look right and wide enough to pass nothing: it becomes a surface drain.
No rodding eye at the ends: the only way in is to lift the whole run.
An insert sealed in place - the joint becomes the reservoir nobody swabs.
What decides the size
What is allowed down it: liquid only, or liquid and fine solids
Cleaning method - if it needs a brush, the slot width follows the brush
Whether it is front of house, which decides the finish and the flush detail
Flow: a slot is chosen for appearance first, and sized second
Where it goes
Open kitchens, pass-throughs, bars, patisserie and front-of-house serveries; prep rooms and central kitchens where the floor is walked on and seen.

09 - Series / SS200X
ProcessTrench 200 Series
One continuous trench across the low edge of a production floor, grating flush, fall built into the body. Everything the shift washes down arrives here - so the trench, not the outlet, is what has to take it.

Length
on request
The trench is sized to the run, not the run to the trench. On a refit that usually means a shorter basket and a deeper body.
How it fails
Sections that do not align at the joint: the step holds water and the squeegee finds it.
An outlet at the low end only, with the fall running the other way: the far end silts up.
A slot grating over a wide body: the gap is what a squeegee pushes into, not out of.
What decides the size
Run length and the fall available across it
Solids: a bar grating is a decision about what you are willing to hand-pick
Whether a pallet truck or racking crosses it - that decides the grating and the load class
Who lifts the gratings, and whether they can lift a section alone
Where it goes
Production halls, washdown lines, breweries and dairies, meat and ready-meal plants, industrial kitchens with intensive washdown.

If the basket needs a tool to open, it will not be opened. That is the whole design brief.
How it fails
A basket that sits below the grate and is invisible: it fills, water backs up, nobody knows why.
Perforations too fine for the solids and too coarse for the water - the wrong trade either way.
A ledge under the basket: everything that passes the perforation settles on it.
What decides the size
Solids size and volume per shift - that is the perforation and the basket depth
Trapped or free-discharging: the answer changes the body, not the basket
Whether a hose is aimed at it, which decides the grating
Which channel it drops into, and at what point in the run
Where it goes
Under sinks and dish tables, at doors and low corners, and in-line on a trench run where solids arrive in bursts.

A cleanout that needs a key is a cleanout that gets sealed shut with mastic and forgotten.
How it fails
A cover sealed with mastic: it becomes a bump in the floor and is never opened again.
A gasket that perishes with no replacement listed, so the cover is left loose.
A frame fixed to the screed only: it rocks under a trolley and the grout line opens.
What decides the size
What crosses it - foot traffic, trolley, or pallet truck
Whether it is for rodding, inspection or sampling
Cover finish: anti-sliding or smooth
Body depth against the slab, and where the run sits below it
Where it goes
The ends of runs, downstream of a DebrisGuard, at the head of a discharge, and anywhere the line has to be reached without lifting a whole trench.

A run is a kit, not a part.
Sections, branches, corners, outlets, end caps and gratings are separate parts from the same
module - so a damaged grating is a part number rather than a new channel.
