Snow Melters.

An industrial snow melter is essentially a large heated tank with a submerged combustion burner. Snow is loaded into the top of the tank by a skid-steer, loader, or conveyor. The burner (diesel, natural gas, or propane) heats water inside the tank to roughly 4–10 °C — warm enough to rapidly melt snow without boiling. Loaded snow contacts the warm water, melts in seconds, and the resulting meltwater discharges through a side outlet into a storm drain, oil-water separator, or holding tank. A 60-tonne-per-hour Trecan unit melts about 200 cubic metres of compacted snow per hour — the equivalent of 20 tandem-axle dump trucks worth of haul-away. Single operator, continuous duty, fuel consumption roughly 25–60 litres per hour depending on size and outdoor temperature.

Snow melters become economic when on-site hauling cost exceeds $4,500 per storm event, which is the typical rental threshold for a 20-tonne-per-hour unit. That math kicks in at roughly 18–20 truckloads per storm. For a typical downtown Toronto, Montréal, or Vancouver commercial property of 100,000–250,000 sq ft, two or three major storms per season produce that volume. Below that, a snow hauling contractor at $250–$500 per truckload is cheaper. The other driver is regulatory: many downtown municipal bylaws (Montréal-Plateau, Toronto Yonge corridor, Vancouver West End) prohibit snow stacking above 1.5 m, which forces either melt or haul. Hospital campuses, airports, and university properties almost always justify on-site melt because of operational risk from stacked snow.

Discharge of snow melter meltwater is regulated under municipal stormwater bylaws. In most Canadian cities the meltwater is discharged to a sanitary or combined sewer through an oil-water separator and grit chamber — the regulations care about hydrocarbons (motor oil, fuel residue tracked in by trucks) and grit (sand and rock chips from winter traction grit) more than the salt or chloride content. Toronto, Montréal, Ottawa, Calgary, and Vancouver require a discharge permit for snow melter operations on commercial sites, typically issued by Public Works or Environmental Services and renewed seasonally. We provide the discharge specifications and template municipal application with every rental quote, and the on-site operator carries the discharge permit during operations.

Rental rates in Canada (2025-26 season) run roughly: 20-tonne-per-hour trailer-mounted unit $4,500–$6,500 per week; 40-tonne-per-hour unit $6,500–$9,500 per week; 60-tonne-per-hour unit $9,500–$13,500 per week; 100-tonne-per-hour airport-grade unit $14,000–$18,000 per week. All rates include delivery, on-site fueling, a trained operator on standby during operations, and the discharge permit application. Fuel consumption is billed separately at cost — typically 25–60 litres of diesel per hour of melt operation. Lead time for delivery during a storm event is 24–48 hours; book a rental on the forecast, not after the storm. End-of-season rates from late March through May drop 30–45 % for spring snow events and breakup operations.

Small-scale snow melters in the 1–5 tonne-per-hour range exist for residential and small commercial use — propane-fired or electric tank units priced from $4,000 to $25,000. They are sometimes used by downtown townhouse owners in Montréal, Old Toronto, and Old Québec where there is genuinely no room to stack snow and where regulations prohibit pushing it to the street. For 95 % of Canadian residential properties they do not make economic sense — a snow blower, a salt application, and an occasional truck haul once or twice a season is dramatically cheaper. We do not list residential snow melters in the commercial catalog; if you have a genuine no-stacking residential constraint, contact us and we will source the right small-scale unit from a specialty distributor.

Trecan, headquartered in Dartmouth, Nova Scotia, is the Canadian-designed and Canadian-built market leader and supplies most of the commercial and municipal fleet across Canada. Snow Dragon, based in Cleveland, Ohio, is the major American-built competitor and is common in the Maritimes, southwestern Ontario, and the Lower Mainland. SND (formerly Snow Diesel) makes mid-range trailer-mounted units popular with contractors. Larue Industriel in Saint-Augustin-de-Desmaures, Québec, builds heavy-duty snow blower and snow melter equipment and supplies several Québec municipalities. All four brands are supported with parts and service across Canada through local dealer networks. We list new units through factory dealers and photo-verified used units from contractor retirements with documented service history.
