For Executive Chefs
Your combi oven is scaling. Your HACCP log doesn't know.

Scale on the steam generator reduces heat transfer and creates hot spots — that’s a food safety risk, not just an equipment cost. TDSBot logs water quality at every appliance continuously, giving you timestamped records for every health inspection and a data-driven descale schedule that isn’t guesswork.

For Facilities Teams
Every appliance. Every site. One dashboard.

Managing water quality across a hotel kitchen means different thresholds for different appliances, different service intervals, and no way to know which one needs attention without walking the floor. TDSBot shows the status of every device in real time — and alerts you before something fails, not after.

Appliance coverage

Every water-using appliance
in your operation

TDSBot installs on the water supply line to each appliance. Different appliance types have different water quality requirements and different failure modes from poor water. One sensor, precisely placed, tracks the metric that matters for each.

Combi Oven
Scale on steam generators costs 8–12% energy per mm

Scale on the steam generator reduces heat transfer and creates hot spots. One millimetre of scale across three combi ovens adds $3,000+ to the annual energy bill.

TDSBot tracks
TDS, estimated cumulative hardness load (derived from onboarded inlet chemistry), estimated scale accumulation, data-driven descale schedule. Alert when threshold is approaching. Hardness and scale figures are estimates — confirm periodically with lab testing.
Warewasher
Spotting and blocked nozzles are water quality failures

Scale blocks spray nozzles, causes rewash cycles, and reduces detergent efficiency by 15–30%. Hard water is the most common cause of spotted glassware.

TDSBot tracks
TDS vs spot-free threshold, filter depletion, % time within set TDS target. Alert when output TDS rises above your spot-free limit.
Ice Machine
Scale on evaporator plates reduces yield and contaminates ice

Above 125 mg/L hardness, scale on evaporator plates reduces ice yield and in extreme cases contaminates ice with calcium flakes. An unmonitored machine can fail a HACCP inspection.

TDSBot tracks
Hardness estimate, cumulative hardness load, data-driven descale interval. Alert before scale affects yield or contaminates product.
Laundry / Linen
Hard water degrades linen quality and increases detergent spend

Above 150 mg/L: faster linen degradation, higher detergent spend, drum scale. TDSBot tracks softener output to confirm treatment is working before quality drops.

TDS output from water softener, hardness estimate, % time within target softness range. Alert when softener resin is exhausting.
Coffee & Beverage
Hotel coffee is often the most visible water quality failure

Guest coffee complaints are usually water complaints. Alkalinity above 75 mg/L dulls extraction; TDS above 250 ppm creates heavy, bitter shots. Full SCA inference and corrosion tracking available.

TDSBot tracks
TDS, SCA inference, LSI + Larson-Skold, cumulative hardness, filter depletion. Full Coffee Pro tier analytics available.
Guest Water Stations
Filtered water amenity needs monitoring too

Guest-facing filtered water is often the least monitored system in a hotel. An exhausted filter supplying unfiltered water is a quality and brand risk.

TDSBot tracks
Filter output TDS, depletion prediction, flow rate, % time in target. Alert before guests notice a change.

Data-driven descaling

Stop descaling on a schedule. Start descaling on data.

TDSBot estimates average hardness (mg/L as CaCO₃) from inlet water chemistry you enter at onboarding — typically from a lab test or utility CCR report — and tracks estimated cumulative hardness load: the calculated total of calcium carbonate passing through each appliance. This estimate is compared against manufacturer-published scale tolerance thresholds. When it reaches the threshold, you descale. Not before. Not after.

% of time water was within your target range

Set a TDS target range per appliance. TDSBot measures every minute and reports the percentage of time filtered water stayed within range. One number per appliance per month — your treatment is either working or it isn't.

89%The warewasher was within its TDS target range 89% of operating time last month. That 11% outside range concentrated in the last 4 days — when the filter was exhausting. TDSBot flagged it on day 2. Service was scheduled before a rewash cycle was needed.

Compliance & documentation

Warranty claims. HACCP audits. Your records are already there.

TDSBot logs continuous TDS and temperature data with timestamps for every device. This record can support warranty assessments and health inspections. Hardness figures are estimates based on onboarded inlet water chemistry — for regulatory purposes, lab-confirmed hardness data may also be required.

HACCP water quality records

TDS and temperature measured continuously by TDSBot sensors and logged with timestamps for every device. Exportable as a dated PDF to support health authority inspections. Total hardness figures shown in reports are taken from the tested water hardness you entered at setup — TDSBot does not measure hardness directly.

Water quality records your warranty team didn't have before

Most hospitality operations have no continuous water quality records at all — if an appliance fails and a warranty question arises, there is nothing to show. TDSBot gives you a continuous, timestamped log of TDS, temperature and flow rate at every appliance. TDSBot does not certify compliance with any standard.

What operators say

From the people running
the kitchens

“We were descaling our combi ovens every 90 days across the property. TDSBot showed us that the kitchen 1 units needed it at 54 days — and kitchen 2 could go to 110 days. We cut our descale chemical spend by 30% and stopped the unplanned downtime that was hitting us in dinner service.”
PLPierre LaurentExecutive Chef · Hotel Méditerranée · Nice, France
“The HACCP documentation alone was worth it. We had a health inspection last quarter — the inspector asked for our ice machine water quality records. I exported three months of timestamped TDS and hardness data in two minutes. She said she'd never seen documentation that complete.”
AKAyşe KılıçFacilities Manager · Grand Hotel Ankara
“Across 18 properties, we were running every filter on a calendar — change every 6 months, regardless of throughput. TDSBot showed us that four high-occupancy properties needed changes at 3.5 months, and two low-occupancy ones hadn't hit 60% depletion at 6 months. We're saving about $40,000 a year in unnecessary filter spend.”

Common questions

From facilities managers
and F&B directors

Hard water above 150 mg/L as CaCO₃ deposits calcium carbonate scale on heating elements, heat exchangers and steam generators. In combi ovens, 1mm of scale increases energy consumption by approximately 8–12% and creates hot spots that damage heating elements. In commercial warewashers, scale blocks spray nozzles and reduces wash temperature. In ice machines, scale on evaporator plates reduces ice production and can contaminate ice. Annual scale-related costs for a mid-size hotel kitchen typically run $8,000–25,000 in energy waste, service calls and reduced equipment life.

Yes. TDSBot devices install inline on the water supply to each appliance category — combi oven, warewasher, ice machine, laundry, coffee station, guest water. Each device reports to the same fleet dashboard with per-device TDS readings, cumulative hardness load, filter depletion forecast, and percentage of time water was within the set target range for that appliance type.

TDSBot estimates average hardness from onboarded inlet water chemistry and tracks cumulative hardness load — the actual grams of CaCO₃ that have passed through each appliance. This is compared against the manufacturer's scale tolerance for that appliance type. When cumulative load reaches the threshold, TDSBot alerts you to descale — before scale accumulation affects efficiency, not on a fixed 3-month or 6-month schedule that may be too early or too late for your specific water and throughput.

A mid-size hotel (100–200 rooms) with a full kitchen typically runs 8–12 devices: 2–3 on combi ovens, 1–2 on warewashers, 1–2 on ice machines, 1 on the laundry feed, 1–2 on the coffee station, and 1–2 on guest water stations. Each device is independent and reports to the same dashboard. You can add or remove devices as your operation evolves.

TDSBot installs inline on the water supply line to each appliance — between the filter outlet and the appliance inlet. Quick-connect fittings work with 1/4″ to 1 1/2″ lines. A skilled facilities technician can install each unit in 15–20 minutes during a brief shutdown of that appliance's water supply. No need to shut down the whole kitchen. Full installation guide and video included.

No — TDSBot monitors water quality; it does not treat water. Your existing softeners, RO systems, and filter cartridges stay in place. TDSBot tells you when those systems are performing, when they're degrading, and when they need service — so you can manage them proactively rather than reactively. Think of it as the intelligence layer on top of your existing water treatment infrastructure.

TDSBot sends alerts and work order triggers via webhook or API to your CMMS. Filter depletion alerts, descale scheduling alerts, and threshold breach alerts can all be configured to create work orders automatically in your maintenance system. We support standard webhook formats compatible with Archibus, IBM Maximo, Planon, and most major CMMS platforms. Custom integrations available at Protect tier and above.

Most hospitality operations have no continuous water quality records at the appliance level — if a warranty question arises, there is nothing to show. TDSBot changes that by providing a continuous, timestamped log of TDS, temperature and flow rate at each device, exportable as a PDF for any date range. What TDSBot records are not: a compliance certificate, a guarantee of warranty coverage, or a substitute for the manufacturer’s own service records. Hardness figures shown in reports are based on the total hardness value you entered at onboarding — typically from a lab test or CCR — not a real-time ion measurement by TDSBot sensors.

TDSBot's account hierarchy supports group → property → appliance in a single dashboard. The group engineering director sees all 15 properties and all devices. Each property manager sees only their own site. Alerts can be routed to the relevant property team, with an escalation roll-up to the group level for critical alerts. Multi-property groups with 100+ devices qualify for volume pricing — contact partners@watertds.com to discuss rates.
