Water Extraction & Drying Equipment in Toronto: What Restoration Pros Use

# Water Extraction & Drying Equipment in Toronto: What Restoration Pros Use

The single biggest visible difference between a professional water-damage response and a DIY attempt is the equipment. A homeowner with a wet-dry vacuum and a couple of box-store fans has a fraction of the extraction capacity, a fraction of the airflow, and zero of the dehumidification capacity required to dry a structure within the IICRC S500 timeline. That capacity gap is why the difference between same-day mitigation and "we'll get to it Monday" is often the difference between a $12,000 claim and a $35,000 mold-remediation claim.

This post walks through the equipment IICRC-certified mitigation teams use in Toronto: extraction tools, air movers, dehumidifiers, thermal imaging, and the psychrometric calculations that determine how it's all sized. For the broader restoration lifecycle, see [Fire & Water Damage Restoration Toronto 2026: Complete Guide](/blog/fire-water-damage-restoration-toronto-2026-complete-guide).

RenoHouse's role: the mitigation phase — including all equipment deployment — is performed by IICRC-certified partners (Restorx Disaster Restoration, ServiceMaster Restore, Steamatic, FirstOnSite, PuroClean). RenoHouse executes the rebuild that follows.

Extraction Equipment

The first job on any water loss is removing standing water as fast as possible. Extraction speed sets the tone for everything else.

Truck-mounted extractors. The workhorses of professional water restoration. These are large vacuum systems mounted in a service van, with capacities of 5–15 gallons per minute (GPM) of pickup. Common units in the Toronto market:

Hydramaster CDS-4.8 / Boxxer 421 — the most common heavy-duty truck-mount. Heated water, high vacuum, dual-3" hose capability.
Sapphire Scientific 870 SS — slim profile fits van layouts; common with smaller fleet operators.
Prochem Performer 405 — economy truck-mount common with newer operators.

A truck-mount can extract a flooded 1,000 sq ft basement in 2–4 hours, vs 12–18 hours for a portable extractor. For Toronto's older homes with deep basements (often 1,200+ sq ft below grade), the truck-mount is the difference between same-day and multi-day extraction.

Portable extractors. When access doesn't permit a hose run from the van, portable units come in. Common picks:

Mytee LTD12 (12-gallon, 200-PSI heated extractor).
Hydroforce Olympus M1200H (12-gallon, heated, dual-stage vacuum).
Phoenix Bandit 12 (compact, single-floor work).

Portables run 12–18 hours of continuous operation per shift. Less aggressive than truck-mounts but indispensable for upper-floor and high-rise condo work.

Submersible pumps. For deep standing water (over 4 inches), high-capacity submersible pumps (Wayne PC4, Liberty 280) move large volumes fast — 50+ GPM — to grates, sumps, or sanitary connections.

Air Movers (Fans)

Once standing water is extracted, the next phase is airflow. Air movers create a high-velocity stream across wet surfaces, accelerating evaporation. The IICRC S500 calculation: one air mover per 10–16 linear feet of wet wall, plus one per 200–300 sq ft of wet floor.

Three air-mover types dominate Toronto restoration fleets:

Axial air movers. High-volume, high-velocity. The most common type for general drying.

Phoenix Axial Air Mover — industry workhorse, 3,200+ CFM, low amp draw.
Dri-Eaz Sahara X3 — 3,300 CFM, very low amp draw (you can run more units per circuit).
B-Air Vento — economy axial unit, common in mid-tier fleets.

Centrifugal "snail" air movers. Tighter, more focused airflow. Common in early-stage drying when concentration on a specific surface matters.

Phoenix Focus — 3,000 CFM in a focused stream.
Dri-Eaz Velo — directional snail, useful for under-cabinet and tight spaces.

Low-profile air movers. For drying carpets, under-cabinet voids, and crawl spaces.

Dri-Eaz Stealth AV3000 — flat profile, fits where standard movers don't.
Phoenix XPS — extra-low-profile for tight access.

A mid-sized Toronto basement loss commonly runs 12–24 air movers in parallel for 3–5 days.

Dehumidifiers

Air movement evaporates water *into* the air. The dehumidifier removes it. Without proper dehumidification, drying just relocates the water from materials into the indoor air, where it eventually re-condenses on cold surfaces or escapes via uncontrolled paths.

Three dehumidifier classes are used in restoration:

Conventional refrigerant dehumidifiers. Older technology, work well above 70°F and 60% RH but lose efficiency in cold or low-humidity conditions. Mostly retired from professional fleets. Low-Grain Refrigerant (LGR) dehumidifiers. The current professional standard. LGR units pre-cool the incoming air, then condense at colder coils, allowing them to extract moisture down to lower grain levels (about 35–40 grains per pound). Common picks:

Phoenix R175 — 175 pints/day, very common in Toronto fleets.
Phoenix DriZone HD — heavy-duty for large-cavity drying.
Dri-Eaz Revolution LGR — 145 pints/day, very efficient.
Dri-Eaz Drizair 1200 — workhorse mid-size LGR.

Desiccant dehumidifiers. Use silica or lithium chloride desiccant wheels to extract moisture in cold or very low-humidity conditions. Required for cold-weather drying when refrigerant units lose efficiency. Common in winter Toronto work or for hardwood floor drying. Common picks:

Phoenix 200 Max — 200 CFM desiccant.
Dri-Eaz Pro 6000 — 600 CFM desiccant for large-volume work.

A typical Toronto basement loss runs 1–3 LGR dehumidifiers; large losses or hardwood-floor scenarios may add a desiccant unit.

HEPA Air Scrubbers

For Category 2 and Category 3 water losses (and any mold-affected scope), HEPA-filtered air scrubbers remove particulates and microbial spores from the work area. They also create the negative-pressure environment that contains contamination during demolition.

Common units in Toronto fleets:

Dri-Eaz DefendAir HEPA 500 — 500 CFM, three-stage filtration.
BlueDri AS-550 — 550 CFM, very common in mid-tier fleets.
Abatement Technologies HEPA-AIRE H800 — 800 CFM for larger jobs.

Air scrubbers run continuously throughout demolition and drying on contaminated jobs. The HEPA filter is changed per OEM schedule (often every 1,000–2,000 hours).

Heat Drying Systems

When ambient temperature is too low for refrigerant dehumidifiers to work efficiently — common in unheated Toronto winter losses — heat drying systems are deployed. These elevate the air temperature in the drying chamber, increasing the moisture-holding capacity of the air and accelerating evaporation.

Common picks:

Dri-Eaz Dragon — recirculating heat-drying system; the gold standard.
Phoenix FireBird — direct-fired heat drying; large-volume capacity.

Heat drying is typically deployed on hardwood floor saves, deep cavity drying, and any winter basement loss where the structure cannot be conditioned to 70°F+ by normal means.

Moisture Detection

The crew chief manages drying based on moisture readings, not visual inspection. Three measurement tools are standard:

Pin moisture meters. Probe-based, contact reading of moisture content as a percentage. Penetrate paint and shallow finishes for substrate readings.

Delmhorst BD-2100 — industry standard for restoration; reads wood (12% target) and drywall (~0.5% target).

Non-invasive scanners. Radio-frequency or capacitive sensors that read moisture without breaching the surface. Useful for upper levels, finished surfaces, and large-area scanning.

Tramex MEP — the dominant non-invasive scanner in Toronto fleets.
Protimeter Surveymaster — dual-mode (pin and non-invasive).

Thermal imaging cameras. Reveal hidden moisture by detecting temperature differentials (wet substrates evaporate, cooling locally). Don't measure moisture directly but identify investigation zones.

FLIR E8 / E96 — industry-standard restoration thermal imager.
Hikmicro M11 — economy alternative gaining adoption.

Standard practice: thermal imaging maps the affected area; non-invasive scanner narrows down; pin meter confirms. The crew chief logs daily readings at fixed points and tracks the curve toward the drying goal.

Drying Chambers and Containment

For large or contaminated jobs, the affected area is sealed off as a "drying chamber" — plastic sheeting (6-mil min) over openings, with the dehumidifier sized to the cubic-foot volume of the chamber. This concentrates the airflow and dehumidification energy where it matters and prevents conditioning the rest of the home.

Polyethylene zipper doors, negative-pressure exhaust to outside (for biohazard), and a HEPA-filtered air scrubber inside the chamber are the standard kit.

Psychrometric Calculations

Drying isn't intuition; it's psychrometrics — the science of air-water vapour relationships. The crew chief calculates the required dehumidifier capacity based on:

Cubic-foot volume of the drying chamber.
Initial grains per pound (GPP) of moisture in the air.
Target GPP at drying goal (usually <50 GPP).
Moisture load from saturated materials (per pound of water that needs to come out of the structure).
Temperature of the chamber (warmer = more capacity, but limited by what the structure can tolerate).

The result is a sized dehumidifier (or multiple units) and a target completion timeline. A small under-sized dehumidifier means materials don't dry on time and have to be replaced — a common low-bid mitigation failure.

Daily Drying Logs

A reputable Toronto restoration team produces a daily drying log:

Date and time of reading.
Moisture content at every metering point (typically 8–20 points per affected room).
Air temperature and relative humidity inside the chamber.
Air temperature and relative humidity outside the chamber (control reading).
Equipment running and equipment changes.
Crew chief notes.

The log is the proof of the work. Adjusters review it. If a future moisture issue arises, the log is the homeowner's evidence that the structure was dried properly.

What This Means for the Homeowner

You don't need to operate any of this equipment. What you do need to do is recognize it on site and understand what to expect:

The crew should arrive with a service van or box truck loaded with the kit above. If they show up with a couple of fans in a pickup, that's a flag.
The drying chamber should be sealed and equipped within the first 24 hours.
Daily moisture logs should be available on request.
Final clearance should be supported by moisture readings demonstrating the drying goal was achieved at every metering point.
